Panorama of a Thousand Black Holes

Today’s astronomy porn comes from the Chandra X-Ray Observatory where the science team has assembled a panorama image revealing more than a thousand supermassive black holes.

Why Do We Need Streetlights that can Guide in the Space Shuttle?

Look at this gawd-awful streetlamp. It is spewing photons all over the place, including people’s eyes when they look at it. Jeebus this irritates me.
Recently I was walking on the downtown mall in Boulder on a nice, cool night. Lots of people, lots of street performers, quite a lovely time. It […]

You’re not drooling over the latest gadgets listed in Penthouse for Astronomers (err, I mean, Sky and Telescope)? Well, I am. Of course, I only read […]

History of the Universe Online Exhibit

I was thumbing through the March issue of Physics Today when I saw a little blurb advertising this:
Cosmic Journey: A History of Scientific Cosmology
This site gives a very thorough account of the history of how we’ve viewed the cosmos. There’s a section on the Greek World view, the ideas of Copernicus, Isaac Newton […]

Google is Getting into the Astronomy Biz

With the advent of larger CCD arrays, improved image time cadence and faster computers, astronomers have been collecting more data than ever. Terabytes of data are being collected and stored from large, ground-based telescopes, space and planetary probes and space-based telescopes.
The challenge these days isn’t collecting the data, but storing, processing, searching and analyzing […]

Intelligent Extraterrestrial Beings Do Not Exist

One of the things I love to do is go through old volumes of astronomy journals and read articles that catch my eye. I know, how sad is that?
One of the really cool benefits of doing it though is that I can read over landmark papers first hand, it gives me a feeling of […]

What Orion Looks Like from My Backyard

Last night, I went out in my backyard to take my estimate of the light pollution present. My backyard is a terrible place for an astronomer, I have three very bright streetlights flooding my backyard with photons. So many in fact that they actually cast a shadow, and I don’t need a flashlight […]

Save Our Skies! Participate in GLOBE at Night Project

We are losing our night skies and from March 8 - 21 you can help do something about it.
Slowly but surely, the stars are fading from view. On average, when we look up at the sky on a clear, dark night, we can see only about 3000 stars and that number is getting smaller […]

Are We Hard-Wired to Believe in God?

OK, wow. I was just posting about how I believe our brains have lots of evolutionary baggage when it is forced to accept new beliefs.
I was just reading this New York Times article on current research that is trying to find out if our brains are wired (by evolution) in specific ways that predispose […]

It’s Reader Appreciation Day at AstronomyBuff

You know, I never expected this blog to get as personal as it has. I’ve written about things I never thought I’d actually share with anyone, but when I’m sitting around, wondering ‘what the hell can I write about today that’s different from all the other blogs?’, stuff comes out that ends up being […]
