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 BorealisShare This:
Astronomy Images and Video
Beautiful and interesting images and video of the night sky including stars, planets, the Milky Way, and deep-sky objects taken through a camera lens or through a telescope.
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 FeetShare This:
The Jellyfish Nebula, also called IC 443, is the sprawling remnant of a massive star that exploded as a supernova some 3,000 to 30,000 years ago in a gas-strewn patch of the Milky Way in the constellation Gemini. As you can see in the above image by Jeff Johnson, the shock wave from the explosion produced the particularly intricate lacework of nebulosity that makes up the Jellyfish. The nebula, which is about 5,000 light years away, is adjacent to a rich region of star formation called Sharpless 249. [Read more…] about The Jellyfish NebulaShare This:
The tiny northern constellation Triangulum contains the gorgeous face-on spiral galaxy Messier 33, also known as the Triangulum Galaxy. A photogenic target for expert astrophotographers, the Triangulum Galaxy is a next-door neighbor of our Milky Way Galaxy and the most distant object you can see with your unaided eye. As you can see in the above image by Terry Hancock and Ron Brecher, the spiral arms of M33 are festooned with pink star-forming nebulae. The largest, NGC 604, is some 100x the size of the Orion nebula and hosts more than 200 massive stars at its center.
The spiral arms of M33 are loosely bound, and the galaxy is a type-Sc spiral using Hubble’s galaxy classification system. The galaxy spans a diameter of 50,000 light years, about half the diameter of the Milky Way. Indeed, M33 belongs to the so-called Local Group of Galaxies which includes the Andromeda Galaxy, the Magellanic Clouds, and our own Milky Way. M33 may itself be a large satellite of the much larger Andromeda galaxy, Messier 31.
(Note: The Triangulum Galaxy is one of the dozens of deep-sky sights featured in The Armchair Astronomer, a collection of astoundingly beautiful images of clouds of gas and dust where new stars are born. If you haven’t yet downloaded this e-book, you can find it here…)
This video shows the best images of the 6th International Earth and Sky Photo Contest, a program by The World at Night (TWAN) in collaboration with the Global Astronomy Month and the National Optical Astronomy Observatory (NOAO). The contest aims to show the natural beauty of starry sky and help preserve the dark skies which are not yet polluted by artificial lights.
