Eclipse from Chongqing Municipality (Xinhua/Liu Chan)

The total solar eclipse which just occurred on the 22nd of July 2009 was the longest maximum duration of the 21st century. Not since Saros 1991 have astronomers and eclipse chasers been treat to such an event! Totality lasted over six and a half minutes at maximum. duration. The event started in India along the western shore near Surat moved towards Butan and reached the southern tip of Nepal and the northern edge of Bangladesh.

For other lucky astronomers like Vietnamese student Dang Anh Tuan at Hanoi National University of Education, the eclipse path also took the event over cities like Chengdu, Suining, Chonging, Wuhan, Xiaogan, Hangzhou, and Shanghai – and event which yielded five minutes of totality. Leaving Shanghai the shadow path raced across the ocean, to fall across islands such as Toshima and Akusaki south of Japan and eventually the Marshall islands. Where was the longest point? The maximum eclipse duration of 6 minutes and 43 seconds occurs far off the coast in the Pacific Ocean! Are you ready to become an eclipse chaser? Then follow me… (...)

Lunar, Solar Eclipses Hold Secrets to Other Worlds

Anne Minard — Wed, 10 Jun 2009 17:17:55 +0000

Want to know about the atmospheres of planets around other stars, and the stars themselves?

Start at home.

A pair of papers in this week's issue of Nature is advocating continued studies of both lunar eclipses, when the Moon transits Earth's shadow, and solar eclipses — when the Moon comes directly between Earth and the sun.

Kaguya Captures Eclipse — From the Moon

Nancy Atkinson — Fri, 20 Feb 2009 00:03:34 +0000

Here's something you don't see everyday. In fact, this is the first time this has ever been seen. On Feb. 10 Japan's Kaguya spacecraft in orbit around the moon successfully took an image of a penumbral lunar eclipse. That's the Earth passing in front of the sun, as seen from the Moon. From the Moon! The image was taken just at the moment when the Earth covered up most of the sun, creating a diamond ring effect. If we're lucky on Earth, we can see this effect in a solar eclipse, when the Moon blocks the Sun as seen from Earth. Here, Earth’s atmosphere is lit up by the sun, creating the ring and just enough sunlight is sneaking by on one side of the Earth, creating the diamond. Sensational! Plus, there's a movie of the eclipse, too!

January 26 Annular Eclipse Photos

Nancy Atkinson — Tue, 27 Jan 2009 03:44:16 +0000

An annular solar eclipse earlier today was visible in South-East Asia, southern Africa and Australia. Thanks to M.R. Taufik from Bontang, Indonesia for sharing this image of a complete ring or annulus of light from the sun peeking out from around the moon. Because the moon's orbit is elliptical, its distance from Earth–and its apparent size—varies. Annular eclipses happen when the moon looks too small to completely cover the sun. Such an event that occurs about 66 times a century.

August 17, 2008 Partial Lunar Eclipse Caught "Down Under"

Tammy Plotner — Mon, 18 Aug 2008 14:42:21 +0000

If you read this week's SkyWatcher's Forecast, then you knew several areas of the world were in for a partial lunar eclipse event. While the Moon basically just did a glancing pass through the umbral shadow, the effect was still dramatic and I was hoping that at least one photographer out there would have a picture and story to share!

Friday's Total Solar Eclipse can be Watched on the Internet

A solar eclipse at totality (NASA/F. Espenak)

If you've ever wanted to see a solar eclipse, this might be the time to do it. It is a very rare chance to see an eclipse at totality because the Moon's shadow is so small and, more often than not, it falls on sparsely populated regions of the planet. Often eclipse hunters are resigned to planning expensive trips to these locations, sometimes only to be disappointed by poor weather. But there's an answer. This Friday's eclipse will swing over Canada, the tip of Greenland, parts of Russia, China and Mongolia, including the Gobi desert, although nothing can replace actually travelling to one of these locations to witness this celestial event, NASA will transmit the eclipse live over the Internet. Excellent, now we can do some eclipse-chasing without leaving our armchairs…

Homer's "Odyssey" May Chronicle Ancient Eclipse

Nicholos Wethington — Tue, 24 Jun 2008 14:50:18 +0000

It's likely that sometime in your education career, an English teacher had you enjoy (or suffer through, depending on your tastes) at least part of that classic of classics, Homer's Odyssey. It tells the story of Odysseus, a Greek general, who embarks on a 10-year journey back home after battling in the fall of Troy. The tale is filled with imagery that is referenced often in contemporary films and books. As old as it is, one would think that we've learned pretty much all we can from the book, but a new analysis of celestial events referenced in the Odyssey reveals that Homer may have documented a total solar eclipse.

Solar Sonic Boom: Eclipses May Generate Atmospheric Shocks

Ian O'Neill — Thu, 22 May 2008 14:39:13 +0000

Something strange happens during a solar eclipse. As the Moon's shadow passes over the surface of the Earth, observers have noticed mysterious bands of shadow ripple ahead and behind the eclipse. It seemed possible that these bands were a result of constructive and destructive interference of sunlight around the limb of the Moon (an effect known as diffraction), or atmospheric turbulence may have had a part to play. However, a new theory has come to light. As the Moon's shadow travels across the Earth's surface, it may be possible that the shadow cools the atmosphere suddenly, creating a pressure difference. This gives rise to a sonic phenomenon: a shock front. This may refract the path of light from the lunar limb and through the atmosphere, creating the bands of light and dark. The solar eclipse may be a sonic phenomenon as well as an optical one…

Send in Your Eclipse Pictures, Tell Your Stories

Fraser Cain — Fri, 22 Feb 2008 17:54:09 +0000

How was your view of this week's lunar eclipse? The skies actually opened up here in Vancouver, and we were able to see good portions of the eclipse. The kids were really excited, and got to stay up late watching the eclipse – it was all they were talking about the next day.

So send me your pictures of the eclipse, and I'll run a quick gallery. Email them to me at info@universetoday.com, and I'll try to post them in the next few days.

And to tide you over, here's an image captured by ESA astronomers from Spain.
