The Aurora…As It Actually Appeared from Alan Dyer on Vimeo.

If you live in a subtropical or temperate part of the globe, or if you live in a light-polluted northern or southern metropolis, you may have gone a long time without seeing a live show of the aurorae borealis or australis. So for your viewing pleasure, I present to you in the above video a real-time view of a recent auroral display that shows a very close approximation what of this famous and mesmerizing upper-atmospheric phenomenon looks like when you see it with your own eye [Read more…] about Real-Time Video of Aurorae Borealis

Video of Solar Eclipse from 35,000 Feet

March 9, 2016 by Brian Ventrudo Filed Under: Astronomy Images and Video

Eclipse expert Mike Kentrianakis captured this video from a Alaska Airline flight 870 from Anchorage to Honolulu. The flight made a planned diversion to intercept the path of the eclipse in the Pacific just north of Hawaii. From this vantage point, with a clear view of the horizon and well above the clouds, it’s easy to see the Moon’s shadow approaching like a storm from a great distance and at a speed of more than 1,200 mph. During totality, the Sun’s chromosphere and corona become visible, with prominences, streamers, and the usual display of the diamond-ring effect and Baily’s Beads just as the eclipse begins and ends [Read more…] about Video of Solar Eclipse from 35,000 Feet

Here’s a little Christmas present from the imaging team in charge of the OSIRIS camera on the Rosetta spacecraft, the little European probe that has been orbiting comet 67P/Churyumov–Gerasimenko. Though they were criticized for keeping the images to themselves for many months, the team has finally released a treasure chest of images online for the first time since Rosetta encountered the comet in August 2014. More images of the comet will be released into the albums in time. You can explore the images and albums of the Rosetta encounter with Comet 67/P at the link above [Read more…] about Fly Along With a Comet

Short Video of Comet C/2015 F4 (Jacques)

July 30, 2015 by Brian Ventrudo Filed Under: Solar System

At the end of July 2015, the little comet C/2015 F4 (Jacques) passes the splendid double star Albireo, the star that marks the nose of Cygnus, the Swan. The comet was discovered on March 27, 2014 by C. Jacques at an observatory in Brazil. The comet is a dim 11th magnitude which makes it a very challenging object for visual observers. It may not get much brighter, but the video below gives you a view of this visitor from the outer solar system.

The video was captured by Tom Wildoner, aka the Leisurely Scientist. He assembled the video from 66 individual 30-second exposures using a Canon 6D and Celestron C6-A SCT on an equatorial mount.

Comet C/2015 F4 makes its closest approach to the Sun on August 10, 2015 at a distance of 1.64 astronomical units.
