Highest resolution mosaic of ‘Tombaugh Regio’ shows the heart-shaped region on Pluto focusing on ice flows and plains of ‘Sputnik Planum’ at top and icy mountain ranges of ‘Hillary Montes’ and ‘Norgay Montes’ below. This new mosaic combines the seven highest resolution images captured by NASA’s New Horizons LORRI imager during history making closest approach flyby on July 14, 2015.

Until barely two weeks ago, Pluto tantalized humanity for eight decades with mysteries we could only imagine – seen as just a point of light or fuzzy blob in the world’s most powerful telescopes.
Now the last explored planetary system in our solar system is being revealed for the first time in history to human eyes, piece by piece, in the form of the highest resolution [click to continue…]

As the morning star, the evening star, and the brightest natural object in the sky (after the Moon), human beings have been aware of Venus since time immemorial. Even though it would be many thousands of years before it was recognized as being a planet, its has been a part of human culture since the beginning of recorded history.
Because of this, the planet has played a vital role in the mythology and astrological systems of countless peoples. With the dawn of the modern age, interest in Venus has grown, and observations made about its position in the sky, changes in appearance, and similar characteristics to Earth have taught us much about our Solar System.

Backlit by the sun, Pluto’s atmosphere rings its silhouette like a luminous halo in this image taken by NASA’s New Horizons spacecraft around midnight EDT on July 15. This global portrait of the atmosphere was captured when the spacecraft was about 1.25 million miles (2 million kilometers) from Pluto and shows structures as small as 12 miles across. The image, delivered to Earth on July 23, is displayed with north at the top of the frame. Credits: NASA/JHUAPL/SwRI
Spectacular imagery of huge regions of flowing ice, monumental mountain ranges and a breathtakingly backlit atmospheric haze showing Pluto as we’ve never seen it before, were among the newest discoveries announced today, July 24, by scientists leading NASA’s New Horizons mission which sped past the planet for humanity’s first ever up-close encounter only last week.
New Horizon’s revealed Pluto be an unexpectedly vibrant “icy world of wonders” as it barreled by the Pluto-Charon double planet system last Tuesday, July 14, at over 31,000 mph (49,600 kph). [click to continue…]

CAPE CANAVERAL AIR FORCE STATION, FL – An advanced military communications satellite that will significantly fortify tactical communications amongst U.S. and allied military forces took flight this evening, July 23, during a stunning sunset blastoff of a United Launch Alliance Delta IV rocket from the Florida space coast as threatening weather luckily skirted away from the launch site in the waning hours of the countdown.

Scientists say NASA’s Kepler Space Telescope has discovered Earth’s “older, bigger first cousin” – a planet that’s about 60 percent bigger than our own, circling a sunlike star in an orbit that could sustain liquid water and perhaps life.

An interesting multiple star discovery turned up in the ongoing hunt for exoplanetary systems.
The discovery was announced by Marcus Lohr of Open University early this month at the National Astronomy Meeting that was held at Venue Cymru in Llandudno, Wales.
The discovery involves as many as five stars in a single stellar system, orbiting in a complex configuration. [click to continue…]

CAPE CANAVERAL AIR FORCE STATION, FL – A high powered military communications satellite for the US Air Force is now slated for launch on a United Launch Alliance (ULA) Delta IV rocket on Thursday evening, July 23, following a scrub called on Wednesday due to powerful thunderstorms passing too close to the Cape Canaveral launch pad in Florida.
Heavy rain and thunderstorms within range of the Delta IV launch pad at Space Launch Complex-37 at Cape Canaveral Air Force Station, Florida, forced ULA to [click to continue…]
The pentaquark, a novel arrangement of five elementary particles, has been detected at the Large Hadron Collider. This class of particles may hold the key to a better understanding of neutron stars and the Universe’s strong nuclear force. (Image Credit: CERN/LHCb experiment)
“Three quarks for Muster Mark!,” wrote James Joyce in his labyrinthine fable, Finnegan’s Wake
. By now, you may have heard this quote – the short, nonsensical sentence that eventually gave the name “quark” to the Universe’s (as-yet-unsurpassed) most fundamental building blocks. Today’s physicists believe that they understand the basics of how quarks combine; three join up to form baryons (everyday particles like the proton and neutron), while two – a quark and an antiquark – stick together to form more exotic, less stable varieties called mesons. Rare four-quark partnerships are called tetraquarks. And five quarks bound in a delicate dance? Naturally, that would be a pentaquark
. And the pentaquark, until recently a mere figment of physics lore, has now been detected at the LHC!
So what’s the big deal? Far from just being a fun word to say five-times-fast, the pentaquark may unlock vital new information about the strong nuclear force. These revelations could ultimately change the way we think about our superbly dense friend, the neutron star – and, indeed, the nature of familiar matter itself. [click to continue…]

The crater that contains those puzzlingly bright spots on Ceres may harbor an equally puzzling haze. Or not. The hints of haze on the dwarf planet, seen in some of the images coming from NASA’s Dawn spacecraft, add another intriguing twist to Ceres’ mysteries.
