Simulating a Supernova in an Aquarium

NOVAE – An aesthetic vision of a supernova from Thomas Vanz on Vimeo.

Astronomers have a reasonably good handle on what happens during a supernova, an immense stellar detonation that occurs when a massive star that’s run out of fuel collapses and explodes with the brightness of 10 billion suns . These events are relatively rare, with just one or two each year, on average, in a galaxy the size of our Milky Way. While the math and physics of a supernova explosion are reasonably well understood, it’s up to visual artists and computer-generated imagery (CGI) experts to help us visualize a supernova explosion in all its glorious violence and complexity [Read more…] about Simulating a Supernova in an Aquarium

Lunar Sunrise, Lunar Sunset

August 24, 2018 by Brian Ventrudo Filed Under: Astronomy Images and Video

The folks at NASA Goddard in Greenbelt, MD, have put together a glorious video of an accelerated sunrise and sunset on the Moon that will reward you with some of the finest images ever taken of our nearest neighbor, and perhaps inspire you to see some of these features with your own telescope. NASA set this visualization of sunrises and sunsets on the Moon to the strains of Claude Debussy’s most famous work, Clair de Lune. Watch the whole thing. It’s a great way to spend a few minutes.

From NASA’s notes [Read more…] about Lunar Sunrise, Lunar Sunset

The Outer Rim of the Milky Way

The outer rim of the Milky Way as seen in late summer towards the constellations Cassiopeia and Perseus.

“Peer at things up close and you may learn their true form
but guessed at from afar, they seem like something else.
Vastness such as this is beyond comprehension:
all I can do is sigh in endless wonder”. – Su Tung-P’o (1060 A.D.)

A Video Retrospective of an Extraordinary Solar Eclipse

August 17, 2018 by Brian Ventrudo Filed Under: Celestial Events

It was the most watched event in astronomical history, and it called forth awe from hardened scientists, barstool astronomers, and small children alike. It was the Great American Eclipse of August 21, 2017. It was a much-hyped and all-to-fleeting event, and like you, I wish I could see it again. We can’t, of course, but we can enjoy the video and images of expert astrophotographers who spent much time and effort documenting this extraordinary eclipse. Here are a few of my favorite videos below… [Read more…] about A Video Retrospective of an Extraordinary Solar Eclipse

The Tears of St. Lawrence

August 10, 2018 by Brian Ventrudo Filed Under: Celestial Events

Perseid meteors appear to emanate from a point (called a radiant) in the northern constellation Perseus. The peak of the meteor shower occurs on or about August 12 each year. Image credit: NASA.

It’s the best celestial show of the northern summer months, one that can be enjoyed without a telescope, camera, or much expertise in celestial matters at all. It’s the Perseid meteor shower, an annual event in which sand-sized bits of an ancient comet streak through the Earth’s upper atmosphere and elicit “oohs and ahhs” from experienced and untutored stargazers alike.
