Space and astronomy news
Europe, the Middle East, and northeast Africa will see the final partial solar eclipse of 2022 next Tuesday.
When it comes to eclipses, a close shave is better than nothing at all. Just such event happens this coming Tuesday on October 25th when the outer shadow of the Moon grazes the northern hemisphere of the Earth, resulting in a fine partial solar eclipse for Europe and surrounding regions.

The first total lunar eclipse of 2021 occurs early next week and features the largest Full Moon of the year.
Ready for the lunar eclipse drought to come to an end? It’s been a while since we’ve watched the Moon pass through the Earth’s dark inner shadow, to be sure. 2020 featured four lunar eclipses… all of which were faint penumbrals. In fact, you have to go all the waaaaay back to January 21st, 2019 (remember 2019?) to remember the last total lunar eclipse. But that wait ends next Wednesday morning on May 26th, with a very short total lunar eclipse, centered on the Pacific region.

By now, you’ve heard the news. One of the top astronomy events for 2019 is coming right up on the night of January 20th into the morning of the 21st with a total eclipse of the Moon. There’s lots of hype circulating around this one, as it assumes the meme of the “SuperBloodWolf Moon eclipse” ’round ye ole web.

Live on the wrong continent to witness the August 21st total solar eclipse? Well… celestial mechanics has a little consolation prize for Old World observers, with a partial lunar eclipse on the night of Monday into Tuesday, August 7/8th.
A partial lunar eclipse occurs when the Moon just nicks the inner dark core of the Earth’s shadow, known as the umbra. This eclipse is centered on the Indian Ocean region, with the event occurring at moonrise for the United Kingdom, Europe and western Africa and moonset/sunrise for New Zealand and Japan. Western Australia, southern Asia and eastern Africa will see the entire eclipse.
The penumbral phase of the eclipse begins on August 7th at 15:50 Universal Time (UT), though you probably won’t notice a slight tea colored shading on the face of the Moon until about half an hour in. The partial phases begin at 17:23 UT, when the ragged edge of the umbra becomes apparent on the southeastern limb of the Moon. The deepest partial eclipse occurs at 18:22 UT with 25% of the Moon submerged in the umbra. Partial phase lasts 116 minutes in duration, and the entire eclipse is about five hours long.
This also marks the start of the second and final eclipse season for 2017. Four eclipses occur this year: a penumbral lunar eclipse and annular solar eclipse this past February, and this month’s partial lunar and total solar eclipse.
Eclipses always occur in pairs, or very rarely triplets with an alternating lunar-solar pattern. This is because the tilt of the Moon’s orbit is inclined five degrees relative to the ecliptic, the plane of the Earth’s orbit around the Sun. The Moon therefore misses the 30′ wide disk of the Sun and the 80′ – 85′ wide inner shadow of the Earth on most passes.
Fun fact: at the Moon’s 240,000 mile distance from the Earth, the ratio of the apparent size of the Moon and the shadow is approximately equivalent to a basketball and a hoop.
When celestial bodies come into alignment, however, things can get interesting. For an eclipse to occur, the nodes – the point where the Moon’s orbit intersects the ecliptic – need to align with the position of the Moon and the Sun. There are two nodes, one descending with the Moon crossing the ecliptic from north to south, and one ascending. The time it takes for the Moon to return to the same node (27.2 days) is a draconitic month. Moreover, the nodes are moving around the Earth due to drag on the Moon’s orbit mainly by the Sun, and move all the way around the zodiac once every 18.6 years.
Got all that? Let’s put it into practice with this month’s eclipses. First, the Moon crosses its descending node at 10:56 UT on August 8th, just over 16 hours after Monday’s partial eclipse. Two weeks later, however, the Moon crosses ascending node just under eight hours from the central conjunction with the Sun, and a total solar eclipse occurs.
Tales of the Saros
The August 7th lunar eclipse is member number 62 of the 83 lunar eclipses in saros series 119, which started on October 14th, 935 AD and will end with a final shallow penumbral eclipse on March 25th, 2396 AD. If you witnessed the lunar eclipse of July 28th, 1999, then you saw the last lunar eclipse in the same saros. Saros 119 produced its last total lunar eclipse on June 15th, 1927.
The next lunar eclipse, a total occurs on January 31st, 2018, favoring the Pacific rim regions.
Partial lunar eclipses have occasionally work their way into history, usually as bad omens. One famous example is the partial lunar eclipse of May 22nd, 1453 which preceded the Fall of Constantinople to the Ottoman Turks by a week. Apparently, a long standing legend claimed that a lunar eclipse would be the harbinger of the fall of Byzantium, and the partially eclipsed Moon rising over the besieged city ramparts seemed to fulfill the prophecy.
In our more enlightened age, we can simply enjoy Monday’s partial lunar eclipse as a fine celestial spectacle. You don’t need any special equipment to enjoy a lunar eclipse, just a view from the correct Moonward facing hemisphere of the Earth, and reasonably clear skies.
See the curve of the Earth’s shadow? This is one of the very few times that you can see that the Earth is indeed round (sorry, Flat Earthers) with your own eyes. And this curve is true for observers watching the Moon on the horizon, or high overhead near the zenith.
This month’s lunar eclipse occurs in the astronomical constellation of Capricornus. The Moon will also occult the +5th magnitude star 29 Capricorni for southern India, Madagascar and South Africa shortly after the eclipse.
Finally, anyone out there planning on carrying the partial lunar eclipse live, let us know… curiously, even Slooh seems to be sitting this one out.
Update: we have one possible broadcast, via Shahrin Ahmad (@shahgazer on Twitter). Updates to follow!
The final eclipse season for 2017 is now underway, starting Monday night. Nothing is more certain in this Universe than death, taxes and celestial mechanics, as the path of the Moon now sends it headlong to its August 21st destiny and the Great American Total Solar Eclipse.

In a classic swords-to-plowshares move, two converted WB-57F aircraft flown by NASA’s Airborne Science Program will greet the shadow of the Moon as it rushes across the contiguous United States on Monday, August 21st on a daring mission of science.
“We are going to be observing the total solar eclipse with two aircraft, each carrying infrared and visible light cameras taking high definition video,” Southwest Research Institute (SwRI) Principal Investigator on the project Amir Caspi told Universe Today. “These will be the highest quality observations of their kind to date, looking for fast dynamic motion in the solar corona.”
Total solar eclipses provide researchers with a unique opportunity to study the solar corona – the ghostly glow of the Sun’s outer atmosphere seen only during totality. NASA plans a battery of experiments during the eclipse, including plans to intercept the Moon’s shadow using two aircraft near the point of greatest totality over Carbondale, Illinois. Flying out of Ellington Field near Houston Texas and operated by NASA’s Johnson Spaceflight Center, NASA is the only remaining operator of the WB-57F aircraft.
Flying at an altitude of 50,000 feet, the aircraft will intercept the 70 mile wide shadow of the Moon. The shadow will be moving at 1,400 miles per hour – twice the speed of sound – versus the WB-57F aircraft’s max speed of 470 miles per hour. The flight will extend the length of totality from the 2 minutes 40 seconds seen on the ground, to a total of about 8 minutes between the two aircraft.
The two converted WB-57F Canberra tactical bombers will track the eclipse using DyNAMITE (Day Night Airbourne Motion Imagery for Terrestrial Environments), two tandem gimbal-mounted 8.7-inch imagers, one for visible light and one for infrared. These are located in the nose of the aircraft and will shoot 30 frames per second.
This system was originally designed about a decade ago to chase down the U.S. Space Shuttle during reentry following the 2003 Columbia disaster and has, on occasion, provided amazing footage SpaceX Falcon-9 Stage 1 returns during reentry.
The solar corona is about as bright as the Full Moon, and the team plans to make a precise ‘map’ of the solar corona in an effort to understand just how the corona interacts with the solar photosphere and the chromosphere. Of particular interest is understanding how wave energy and ‘nanoflares’ heat the solar corona.
“What we’re hoping to learn is what makes the corona so hot, with temperatures of 1 to 2 million degrees Celsius — or even 4 to 10 million degrees Celsius in some regions — far hotter than the photosphere below,” Caspi told Universe Today. “What keeps it organized in terms of structure? Why don’t we see a snarled, tangled mess?”
As a secondary objective, the team will also make observations of the planet Mercury in the infrared 30 minutes before and after totality, located 11 degrees to the east of the Sun during the eclipse. Mercury never strays far from the Sun, making it a tough target to study in the infrared as seen from the Earth.
And of course, all of this has to happen during the scant few minutes up to and during totality. Each aircraft will fly just inside opposite ends of the shadow of the Moon in a challenging long distance precision formation.
The WB-57F aircraft will also participate in a tertiary objective, hunting for Vulcanoid asteroids near the Sun during the eclipse. Though the 19th century idea of a tiny inter-Mercurial world perturbing Mercury’s orbit was banished to the dust bin of astronomical history by Einstein’s general theory of relativity, there’s still room for undiscovered asteroids dubbed ‘Vulcanoids’ close in to the Sun. NASA flew observations hunting for Vulcanoids aboard modified F-18 Hornet aircraft in 2002 scanning twilight realms near the Sun, and came up with naught.
Eclipse chaser Landon Curt Noll noted during an interview with Universe Today in 2015 that NASA’s Solar Heliospheric Observatory SOHO mission has pretty much ruled out objects brighter than +8th magnitude near the Sun, which translates into asteroids 60 kilometers in diameter or larger.
“We have searched down to magnitude +13.5,” Noll told Universe Today. “Assuming the objects are ‘Mercury like’ in reflectivity (in) the Vulcanoid zone (0.08 to 0.18 AU from the Sun), the search has looked for and failed to find objects as small as 2 to 6 kilometers in diameter.” NASA’s Mercury Messenger carried out a similar search en route to the innermost planet.
Knoll has scoured the sky near the eclipsed Sun with a specialized near-infrared telescope rig during the 2006 total solar eclipse over Libya. Next month, he plans to continue his quest from a site near Jackson Hole, Wyoming.
The action leading up to the the long awaited August 21st total solar eclipse begins at 17:16 Universal Time (UT)/ 10:16 AM Pacific Daylight Saving Time (PDT), when the Moon’s dark inner shadow or umbra touches down along the Oregon Pacific coast. From there, the 70 mile wide shadow will race eastward, gracing 14 states (just nicking Iowa and Montana) before departing land over the Atlantic coast of South Carolina 92 minutes later. Viewers along the path will witness a maximum totality of 2 minutes and 40 seconds, centered on a location very near Carbondale, Illinois. Millions are expected to make the pilgrimage to the eclipse path, while those outside the path in the remainder of North America as well as northern South America, western Africa, Europe and northeast Asia will see varying levels of a partial solar eclipse.
This is the end of a long “total solar eclipse drought” for the United States, marking the first time totality touched the continental United States since February 26, 1979, (totality crossed Hawaii on July 11th, 1991). The last total solar eclipse to cross the United States from coast-to-coast was June 8th, 1918.
NASA has a long history of airborne astronomy campaigns. Noll notes that NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) flying observatory based out of Armstrong research center would make an ideal platform for Vulcanoid hunting during totality. Looking at SOFIA’s flight schedule, however, reveals no plans to carry out such a chase on August 21st. SOFIA’s predecessor, the Kuiper Observatory built into a U.S. Air Force C-141 Starlifter discovered the rings of Uranus during a stellar occultation in 1977.
“This is the first use of DyNAMITE and NASA’s WB-57F platform for astronomy,” Caspi told Universe Today. “This showcases the potential for the platform for possible future observations.”
The DyNAMITE/WB-57B campaign will also be part of the live NASA TV webcast on eclipse day.
Airborne total solar eclipse chasing goes all the way back to August 19th 1887, when Dmitri Mendeleev (he of the periodic table) observed totality from aloft. There’s a great old video of an effort to chase a 1925 total solar eclipse using the airship the USS Los Angeles:
A team also chased a total solar eclipse across North Africa on June 30th, 1973 aboard a supersonic Concorde:
Today, you can even book a ticket for an eclipse-chasing experience aloft. Alaska Airlines plans to attempt to duplicate its 2016 success, and will once again chase totality with a lucky few observers aboard next month.
As for us, we’re planning on watching the eclipse from terra firma at the Pisgah Astronomical Research Institute (PARI) in North Carolina while intrepid researchers fly high above. Watch for our complete eclipse guide out around July 21st on Universe Today and an update on weather prospects, solar activity etc. about a week prior. Finally, we’ll have an after action report out post total solar eclipse, with reader images from across the country.

Ready for the “Great American Eclipse?” We’re now less than six months out from the long-anticipated total solar eclipse spanning the contiguous United States from coast-to-coast. And while folks are scrambling to make last minute plans to stand in the path of totality on Monday, August 21st 2017, a unique project named the Eclipse Megamovie 2017 seeks seeks to document the view across the entire path.
The Project: Sponsored by Google’s Making & Science Initiative and led by Scott McIntosh from the National Center for Atmospheric Research’s High Altitude Observatory and Hugh Hudson from the University of California at Berkeley, the Eclipse Megamovie Project seeks to recruit 1,500 observers stationed across the eclipse path from Oregon to South Carolina. Although individual observers will only experience a maximum totality length of 2 minutes and 40 seconds, the complete span of the Eclipse Megamovie will last 90 minutes, compiled using observer images from coast-to-coast.
“The movie is a tool for scientific exploration,” Hudson said in a recent University of California at Berkeley press release. “We’ll be collecting this level of data for the first time, from millions of observers, and it will be a valuable archive. But we don’t know what we’ll see or what we’ll learn about the interactions between the chromosphere and the corona.”
One portion of the project will have trained volunteers image the Sun from along the eclipse path using DSLRs, while another portion of the project will feature smartphone users imaging totality using a forthcoming Eclipse Megamovie app for a full length lower resolution movie.
Bikers and Baily’s Beads
The only total solar eclipse for 2017, totality for this eclipse occurs along a 114 kilometer-wide path touching on 12 states. Millions live within an easy day drive of the eclipse path, so expect lots of general public interest leading up to eclipse day. August is RV and camping season, so expect camplots to fill up quickly as well. The eclipse also occurs just over a week after the annual Biker’s Rally in Sturgis, South Dakota, affording motorcyclists a chance to stand in the shadow of the Moon en route to the annual pilgrimage.
The last total solar eclipse to cross one of the 50 United States graced Hawaii on July 11th, 1991, and the last time the umbra of the Moon touched down over the lower 48 states was on February 26th, 1979 across the United States northwest. But you have to go all the way back over almost a century ago to June 8th, 1918 to find an eclipse featuring totality which exclusively spanned the United States from sea to shining sea.
Observers have chased after the umbra seeking to extend fleeting totality before. Eclipse chasers documented the January 24th, 1925 eclipse from aloft aboard a dirigible over New York City. On June 30th, 1973, a supersonic Concorde flight chased the umbra of the Moon across northern Africa, extending totality out to 74 minutes.
The team was also on hand to perform a dry run test of the Megamovie Project at this past weekend’s annular eclipse which crossed South America, the Southern Atlantic and Africa and reports that the field test of the promised project app by Mark Bender worked admirably, and the Eclipse Megamovie App should be available to the general public soon.
What sort of science can such a project offer? What is left to learn from a total solar eclipse after centuries of scientific study? Well, some of the most accurate measurements of the solar diameter and the size and shape of the Sun have been made during solar eclipses. A long movie may also reveal streamers and development of the solar corona, the ethereal pearly white glowing outer atmosphere surrounding the Sun. About half as bright as a Full Moon, we only get a brief glimpse of the corona during totality. Also, the Eclipse Megamovie will get another shot at the project in April 2024, when another eclipse crosses the United States from Texas to Maine.
The Eclipse Megamovie is taking volunteers now. The gear setup required is simple, and you might have what’s needed to image the eclipse laying around already.
You’ll need a DSLR camera with a sturdy tripod, a zoom or fixed lens of 300mm focal length or better, and an ability to nail down your GPS location and the time to the nearest second. Once the volunteers are selected, training will be provided to include GPS and time stamping images, flat-fielding and more.
Phone apps will readily supply the GPS part. For time, I’d go with with WWV Radio, which broadcasts a continuous audio time hack out of Fort Collins, Colorado. This is in Universal Time, and has an accuracy of better than a second better than online time sources, which occasionally lag due to spurious web connections.
Keep in mind, you’ll be photographing the eclipsed Sun during very brief moments of totality. You’ll need to have approved solar glasses and filters in place during all partial phases leading up to and immediately after the eclipse. The Eclipse Megamovie project also hopes to catch sight of the Bailey’s Beads phenomenon as final streamers of sunlight pour through the lunar valleys, giving the illusion known as the Diamond Ring effect.
And us? We’ll be casting our hubris at the Universe and catch the eclipse from Columbia, South Carolina. We’re heeding the advice of veteran eclipse chasers, and simply enjoying our first eclipse, and imaging our second, though we may sneak in a few shots for the Eclipse Megamovie project. Universe Today publisher Fraser Cain and astronomer and AstronomyCast host Pamela Gay will lead a group watching from southern Illinois, and we’ve also heard from many other observers from around the world who’ll be visiting the U.S. the August… where will you be?
And we’ve already got a spot picked out for 2024, as the next total solar eclipse crosses Aroostook County and our hometown of Mapleton, Maine… hey, you can never start planning too early, right?
Get set for an eclipse for the ages, and be sure to contribute to the Eclipse Megamovie Project.

In Africa this week? The final solar eclipse of 2016 graces the continent on Thursday, September 1st. This eclipse is annular only, as the diminutive Moon fails to fully cover the disk of the Sun.
The 99.7 kilometer wide path crosses the African countries of Gabon, Republic of the Congo, Democratic Republic of the Congo, Tanzania, Mozambique and Madagascar. The antumbra (the ‘ring of fire path of the shadow annulus as viewed from Earth) touches down in the southern Atlantic at 7:20 Universal Time (UT) on September 1st, before racing across Africa and departing our fair planet over the Indian Ocean over four hours later at 10:55 UT. Partial phases for the eclipse will be visible across the African continent as far north as southern Morocco, Egypt and the southwestern portion of the Arabian peninsula.
Tales of the Saros
This eclipse is member 39 of 71 solar eclipses for saros 135, which runs from July 5th, 1331 to August 17th, 2593. This series finally produces its first total solar eclipse on March 29, 2359.
Annular eclipses occur when the Moon is too distant to cover the Sun as seen from the Earth. The Moon reaches apogee, or its most distant point from the Earth on September 6th, just five days after New and the September 1st eclipse.
How common (or rare) are solar eclipses, annular or total? It’s worth noting that as the 2017 total solar eclipse crossing the contiguous United States approaches, creationist websites are again promoting the idea that the supposed ‘perfection’ of solar eclipses is evidence for intelligent design. If solar eclipses are an example of a higher plan to the cosmos, they’re not a very good one… in fact, in our current epoch, partial eclipses, to include annulars, are much more prevalent. If, for example, the Moon’s orbit was aligned with the ecliptic, we’d see two eclipses – one lunar and and one solar – every month, a much rarer circumstance… a creator could have really used that to really get our attention. And Earth isn’t alone in hosting total solar eclipses: in our own solar system, you can make a brief visit to Jupiter’s large moons and also witness total solar eclipse perfection.
Unlike a total solar eclipse, proper eye protection must be worn throughout all stages of an annular eclipse. We witnessed annularity from the shores of Lake Erie back in 1994, and can attest that a few percent of the Sun is still surprisingly bright. The tireless purveyors of astronomy over at Astronomers Without Borders are working to distribute eclipse glasses to schools and students along the eclipse path.
Are you in the path of this week’s annular eclipse? Let us know, and send those images in to Universe Today on Flickr.
We’ll most likely see more than a few images of the eclipse from space as well. And no, we’re not talking about the cheesy composite that now makes its rounds during every eclipse… solar observing satellites to include the European Space Agency’s Proba-2 and the joint JAXA/NASA Hinode mission typically capture several successive eclipses as they observe the Sun from their vantage point in low Earth orbit.
At this stage, we only know of one webcast set to broadcast the eclipse live: the venerable Slooh website.
Let us know if you’re planning on setting up an ad hoc live webcast of the eclipse, even from outside the path of annularity.
And of course, the big question on every eclipse-chaser’s mind is: when’s the next one? Well, we’ve got a subtle penumbral eclipse on September 16th, 2016, and then the next solar eclipse is another annular favoring Argentina, Chile and the west coast of southern Africa on February 26th, 2017.
Don’t miss this week’s annular solar eclipse, either live online or in person, for a chance to marvel at a celestial phenomenon we all share in time and space.
-Eclipse… science fiction? Yup… read Dave Dickinson’s eclipse-fueled tales Peak Season, Exeligmos, Shadowfall and The Syzygy Gambit.
One. More. Year. Quick; where will you be this time next year on August 21st, 2017? We’re now just one year out this weekend from a fine total solar eclipse gracing the United States from coast to coast. If you think one year out is too early to start planning, well, umbraphiles (those who chase the shadow of the Moon worldwide) have been planning to catch this one now for over a decade.
Get set for the Great American Eclipse. The last time a total solar eclipse made landfall over a U.S. state was Hawaii on July 11th, 1991, and the path of totality hasn’t touched down over the contiguous ‘Lower 48’ United States since February 26th, 1979. And you have to go all the way back over nearly a century to June 8th, 1918 to find an eclipse that exclusively crossed the United States from the Pacific to the Atlantic Coast.
Totality for the August 21st, 2017 eclipse crosses over many major cities, including Columbia South Carolina, Nashville, St. Louis and Salem, Oregon. The inner shadow of the Moon touches on 15 states as it races across the U.S. in just over an hour and a half. The length of totality is about 2 minutes in duration as the shadow makes landfall near Lincoln City, Oregon, reaches a maximum duration of 2 minutes, 42 seconds very near Carbondale, Illinois, and shrinks back down to 2 minutes and 35 seconds as the shadow heads back out to sea over Charleston, South Carolina.
The eclipse will be a late morning affair in the northwest, occurring at high noon over western Nebraska, and early afternoon to the east. ‘Getting your ass to totality,’ is a must. “But I’ve seen a partial solar eclipse,” is a common refrain, “aren’t they all the same?”
Nope. We witnessed the May 10th, 1994 annular eclipse from the shores of Lake Erie, and can tell you that even less than 1% of the Sun’s intensity is still pretty bright, a steely blue luminosity equivalent to a cloudy day.
We crisscrossed the United States along the eclipse path back in 2014, chronicling preparations in towns such as Columbia and Hopkinsville, Kentucky. Last minute accommodation is already tough to come by, even one year out. Cabins in the Land Between the Lakes region near Paducah, Kentucky, for example, were booked full as soon as the August 21st date became available. Think Mardi Gras and DragonCon, rolled into one. Hopkinsville also has an annual Roswell-style UFO-fest on the same date, celebrating the 1955 Kelly-Hopkinsville UFO incident.
Will it be ‘umbraphiles versus aliens?’
Out west, enticing locales include the Grand Teton National Park and Jackson Hole, Wyoming and the northern edge of the Craters of the Moon National Monument site in Idaho. It’s also worth noting that the western United States is a better bet cloud cover-wise, as afternoon summer thundershowers tend to be the norm for the southeast during late August.
Millions live within an easy day drive of the eclipse path, and it happens during prime camping season, to boot. The annual Sturgess motorcycle rally held near Rapid City, South Dakota is just one week prior to totality, and bikers returning from the pilgrimage southward could easily stop to greet the Earth’s shadow on the road home.
2017 Eclipse Panorama from Michael Zeiler on Vimeo.
There’s been talk that Cosmoquest may mount an eclipse expedition based out of Nashville, Tennessee (more to come on that).
Maintaining mobility is the best bet. Our master plan is to return to the States a week or so prior, rent a camper van from Vegas, and head northward. Like millions of Americans, this will be our first total solar eclipse, and the event promises to spark a whole new generation of umbraphiles. And stick around just seven more years, and totality will again cross the United States on August 8th, 2024 from the southwest to the northeast. The Illinois, Missouri and Kentucky tri-state region sees this eclipse as well. This one is special for us, as it crosses over our hometown of Presque Isle, Maine. I remember looking up the next total solar eclipse over northern Maine as a kid, way back when, and figuring out just how old I would be. The top of Mount Katahdin and selected sites along the Maine Solar System model would all be choice locales to view this one. Check out this great old vid of the aforementioned 1979 eclipse over the U.S.:
We also plan on taking the veteran eclipse-chaser’s mantra of ‘experience your first eclipse; but photograph your second one.’ to heart. Lots of fascinating projects are afoot leading up to the 2017 total solar eclipse, including The Eclipse MegaMovie Project to produce a complete video documentary of the eclipse path, plans by a student group to fly and observe the eclipse from balloons during totality, proposals to replicate famous eclipse experiments and more. It’s also worth noting that the bright star Regulus will sit just one degree from the Sun during totality… perhaps someone will manage to measure its deflection via General Relativity in a manner similar to Sir Arthur Eddington’s famous 1919 observation?
Unlike the paths of most eclipses, which seem to have an affinity for wind-swept tundra or remote swaths of desert, this one is sure to draw in the ‘astronomy-curious’ and may just be the most witnessed total solar eclipse in history.
Here’s some eclipse tales and facts to ponder leading up to totality. If you caught the August 11th, 1999 eclipse across Europe, then you saw the last eclipse in the same saros series 145. If you caught the eclipse before that in the same series on July 31st, 1981 across northeast Asia, then you’ll complete a 54 year long triple-saros period after seeing next summer’s eclipse, known as an exeligmos. This cycle also brings the eclipse path very nearly back around to the same longitude.
The Sun is about 400 times larger than the Moon in diameter, but the Moon is 400 times closer. We’ve actually heard this fact tossed out as evidence for intelligent design, though it’s just a happy celestial circumstance of our present era. In fact, annular eclipses are now slightly more common than totals in our current epoch, and will continue to become more so as the Moon slowly recedes from the Earth. Just under a billion years ago, the very first annular eclipse of the Sun as seen from the Earth occurred, and 1.4 billion years hence, the Earth will witness one last brief total eclipse.
But you won’t have to wait that long. Don’t miss the greatest show in the universe next August!
