Astro-Vid Of the Week: Stalking the Elusive Annular Eclipse

A simulation of the April 29th eclipse from 1 km above the Arctic.

Created using Stellarium.

This Tuesday, a “ring of fire” annular eclipse will occur that no human eye will witness. This is because the path of the April 29th annular eclipse only briefly touches down for just over 12 minutes over a remote area of Antarctica. In fact, the central part of the Moon’s shadow — known as the “antumbra”— will be for the most part cast off into space, missing our planet entirely.

Watch Today’s Annular Eclipse Live From Australia!

Ready for the first solar eclipse of 2013? As we head toward the start of today’s annular solar eclipse, we thought we’d do something special and offer you an embedded player to watch the eclipse live from Australia. There’s no word on whether the broadcast embedded below will be live from the path of annularity or if the event will be a deep partial from the location presented, but hey, its worth checking out! For a complete discussion of today’s annular eclipse, see our write up on Universe Today.

Astro-Event: The First Lunar Eclipse of 2012.

(Note: I know, we promised a post on Xi Ursae Majoris this week; upcoming events prompted a last minute scheduling change. Trust me, it’s in the pipeline for July!)

A little over 24 hours prior to the big ticket transit of the planet Venus on June 5th-6th is another interesting astronomical event, perhaps less sexy, but worth noting. [Read more...]

It happens sometimes in the world of astronomy journalism. One of the funniest stories I’ve ever heard science journalist Bob Berman tell was that of an irate eclipse chaser. He had used his erroneous article based on a faulty prediction to plan his vacation to St. Kitts, which lay well outside of the path of totality. [Read more...]

AstroEvent: A Pacific-Spanning Annular Eclipse!

Live on the west coast of the United States? This weekend, you will get to witness a rare astronomical spectacle, the likes of which the continental U.S. has not seen since 1994.  On May 20th (21st across the International Date Line) an annular solar eclipse graces our fair planet. This eclipse is “annular” in the aspect that the Moon will be only 31 hours from an apogee of 406,450 kilometers around the time it passes between the Earth and the Sun, and thus will appear too small to cover the disk of our nearest star, as it normally does during a total solar eclipse.

AstroEvent: Will Anyone Welcome the New Saros?

A Remote partial for the hardcore…(Credit: Eclipse Predictions by Fred Espenak, NASA/GSFC).

This week, we’d like to turn your attention to a unique event that no one but a few penguins may witness. July 1st kicks off the month with a partial eclipse of the Sun, the second solar in the past month and the third eclipse overall. The penumbra of the Moon will barely kiss the Earth from 07:53 to 9:22UT and greatest eclipse is a paltry 9.7% around 8:39UT. [Read more...]

January 2010: Life in the Astro-Blogosphere.

Ahhhh…. Another decade is upon us. It’s hard to believe that only ten brief years ago, we had yet to land a probe on Titan, only a handful of exo-planets were known, cell phones were bricks, and a “Gig” was still the pinnacle of computing power. As 2010 is upon us, we realize that we have yet to travel in air locks or have phasers at ready on our hips. Of course, science has made some of our futuristic dreams come true; we now routinely don more computing power on our ears than sent man to the moon, and everything is made of plastic…
