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 AquariumShare This:
Here’s a short video to brighten your day. The writer and film maker Wylie Overstreet took his big 12″ Newtonian telescope into the streets of Los Angeles to show the Moon to passersby. The result? Well, see for yourself. But it’s nice to know that so many overstimulated city dwellers can still enjoy nature at its finest.
You can see a thousand pictures of the Moon, but it’s never the same experience as seeing it for yourself, especially through a good telescope. Even if you don’t know the name of a single crater or sea, the Moon’s stark beauty, the etched features and long shadows and large range of gray scale and brightness, make it one of the most appealing and accessible sights in the sky. And as more experienced stargazers know, you can get the same experience when seeing much fainter objects. With a little practice, of course.
This fine little production is a great reminder that we should look up more often. And when possible, share what you see with those around you.
This is the first in a series of short documentary videos about amateur astronomers, star parties, and the lure of the night sky. It was created by Jon Baker at Stab You Productions and supported by the folks at Explore Scientific. Been a while since you’ve brought your telescope out? Then play this video for a little inspiration…Share This:
Here’s an incredible video that’s as close as it comes to the actual feeling of being under a clear dark sky. Created by Ben Canales and John Waller of Uncage the Soul Productions, this short work features 20 high-school students at a summer astronomy camp in Oregon. The producers simply ask, “What do you feel?” The film also visits the Oregon Star Party where 600 astronomers camp out with their scopes.
This isn’t a timelapse. It’s a video of the night sky in real time. It shows what’s possible with current camera technology, in this case a Canon MH20f-SH set at ISO400,000, along with a fast 20 mm Sigma Art lens.
In this video, along with wide-field views of the late-summer sky, you can see stars reflected in the primary mirror of a big Dob as it turns, a live view of the star Capella through an eyepiece, and a view of the Perseid meteor shower. Just amazing.Share This:
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:
