Experience Eclipse Totality (VIDEO)

Totality — that brief period during a solar eclipse when the Moon is completely centered in front of the Sun’s disk — is a truly amazing sight, so much so that many people who have seen it once (a privileged group that doesn’t include me, sadly!) will travel across the globe in an effort witness it again and again.

During solar eclipse totality the sky not only becomes dark, dropping the temperature and sometimes even allowing stars to be seen, but also the Sun’s outer atmosphere is revealed around the silhouette of the Moon for a few short moments. Unfortunately this is not easily captured on camera because of the rapidly changing lighting situations, and when it is it pales in comparison to the real thing (or so I hear.)

“Diamond ring” effect seen during the Nov. 2012 total solar eclipse

The video above, taken during the November 14 eclipse from Queensland, shows the moments of totality pretty nicely although the streamer effect can’t really be made out. Still, we get a good idea of how the light changes and we can see another effect called “Baily’s Beads”, where sunlight peeks through some of the relief of the Moon’s terrain along its outer limb. Also the “diamond ring” effect can be seen as the Sun is uncovered.

Enjoy, and thanks to YouTube user solareclipse eclipsevidgvale for the upload!

Watch Today’s Total Eclipse Live

Today, tens of thousands of people are gathering in northeastern Australia to witness one of the most amazing and dramatic astronomical events known: a total solar eclipse. At 2:39 p.m. EDT (19:39 UT) the Moon will begin to pass in front of the Sun for viewers around Cairns, Australia, leading up to a brief period of totality at 5:12 p.m. EDT (22:12 UT). At this time, the Sun will be completely blocked by the disk of the Moon, revealing the wispy strands of the Sun’s outer corona. It will be a spectacular view that’s possible at no other time, and will give scientists a chance to study some curious aspectsof the Sun’s atmosphere.

“On a scale of one to ten, a total solar eclipse is a MILLION.” – Fred Espenak, aka “Mr. Eclipse

A Frightful Eclipse Seen From Mars

Yes, Mars gets eclipses too! This brief animation, made from ten raw subframe images acquired with Curiosity’s Mastcam show the silhouette of Mars’ moon Phobos (named after the Greek god of fear) as it slipped in front of the Sun’s limb on September 13 — aka the 37th “Sol” of the mission.

The animation spans an actual time of about 15 minutes.

Soaring Over a Shadow: An Eclipse Seen From Space

The May 20 annular eclipse, seen by many around the world as a “ring of fire” in the sky, was also seen by the astronauts aboard the ISS — although they also got a great view of the shadow that the Moon cast on the Earth as well! This HD video, a time-lapse made from individual photos acquired by Expedition 31 crew members, shows the hazy shadow of the Moon on top of clouds over the Pacific on May 20, 2012 as the Station passed by.

Annular Eclipse Seen From The Moon

The May 20 annular eclipse may have been an awesome sight for skywatchers across many parts of the Earth, but it was also being viewed by a robotic explorer around the Moon!

During the event NASA’s Lunar Reconnaissance Orbiter turned its camera to look back home, acquiring several images of the Earth with the Moon’s fuzzy shadow cast onto different regions during the course of the eclipse. The image above is a 4-panel zoom into one particular NAC image showing the Moon’s shadow over the Aleutian Islands.

And The Sun Is Eclipsed By The Moon

If you didn’t get a chance to see the annular eclipse from where you are, either due to weather or location, here’s a shot of it I managed to grab from Dallas, TX just as the Sun emerged from some low clouds and right before it set beyond the trees.It was visible for perhaps five minutes, but what a great view!

See another shot below:

Watch Tonight’s Eclipse Live!

If you can’t see the annular eclipse occurring tonight from where you are, you can watch it LIVE here on LITD! The feed above (providing it’s not over capacity) will be aired from Petroglyph National Monument in New Mexico, beginning at 9 pm Eastern time — right in prime U.S. viewing location! You won’t need to purchase plane tickets or any special eyewear to watch the eclipse safely from your own computer. :)

The National Park Service will feature a live feed of the May 20 eclipse from Petroglyph National Monument in NM. (NPS)

Viewable from the western US, the Pacific and eastern Asia, the eclipse will feature a “ring of fire” at totality created by the Moon passing in front of the Sun — but at a distance where the Sun is not completely covered. (As a result there’s still a lot of UV radiation coming from the Sun, so as always don’t observe the Sun directly without adequate protection.. find out how to safely view eclipses here.)

The video is provided by LiveStream, the National Park Service and the U.S. Department of the Interior.
