Time lapse: Helvetia’s Dream

November 6, 2012 | By

Oh my, another lovely night sky (and landscape!) time lapse video; this time from Alessandro Della Bella, and called Helvetia’s Dream: [Make sure you set it to hi-def and make it full screen.] I love the opening shot! Unless it was just digitally zoomed, it must have taken some planning; you have to know just […]

They Came From Outer Space

October 31, 2012 | By

Space is scary. Supernovae explode, flooding their neighborhood with deadly high-energy light and blasting superheated matter outward at a large fraction of the speed of light. Black holes gobble down everything around them, and they’re sloppy eaters, spewing out deadly radiation and belching vast winds of gas. Galaxies collide, asteroids impact, entire worlds are chewed […]

Hubble’s Carineidolia contest

October 14, 2012 | By

On April 24, 2007 – the 17th anniversary of Hubble’s launch – the Space Telescope Science Institute released a devastating picture of the Carina Nebula, a ridiculously complex and gorgeous star forming region about 7500 light years from Earth. Here’s the picture: Like I said, gorgeous! [Click to keelhaulenate.] Any structure with that kind of […]

Science Ranch 2012

October 11, 2012 | By

Science Ranch 2012 has wrapped up, and it was way, way too much fun. Quick background: my wife Marcella and I started up Science Getaways, where we create vacation packages and add science to them. We figured we love learning about the places we visit; their natural wonders, the geography, biology, and more, so why […]

The Sky Is Calling

October 9, 2012 | By

So I sit down to go through my email, and it’s the usual slew of press releases, spam, space enthusiast questions, and marriage proposals. No, wait, I don’t get those last ones. Still, it’s a lot of email. But one cataches my eye. The subject line is "Space Pop". Just that. Huh. So I click […]

Jaw-dropping rotating 3D nebula

October 8, 2012 | By

A little over 2000 light years away, toward the constellation of Cepheus, is a place where stars are being born. It’s a nebula, a gas cloud, and it’s called IC 1396. It’s monstrous, well over a hundred light years across – even at its tremendous distance, it’s wider than six full Moons in our sky. […]

The Helix has pink eye

October 4, 2012 | By

One of the most amazing objects in the sky is the Helix Nebula, an expanding cloud of gas and dust surrounding a dying star. This type of object is called a planetary nebula, and it’s formed when a star a bit more massive than the Sun turns into a red giant and blows off its […]

Time lapse: stunning Australian skies over a pathfinding array

October 3, 2012 | By

In the Australian Outback, hundreds of kilometers from the noise and lights of any city, stand three dozen radio telescopes, each a dozen meters across. Working as a single unit, they patrol the skies looking at cosmic objects emitting low-energy light. Photographer Alex Cherney visited this remote observatory and created a really lovely time lapse […]

A whole star exploded, and no one told me?

September 24, 2012 | By

One of my favorite things to do in the whole world is look at astronomical images. They are a source of great beauty, insight into our Universe, and wonder that we can understand them. As it happens, I spent a solid chunk of my professional research career looking at supernovae remnants, the expanding debris after […]

According to my software, this blog post you are reading is the 7000th article I have published on the Bad Astronomy Blog. Wow. That’s a lot of words. It’s also a lot of astronomy, geekery, science, antiscience, web comics, puns, embiggenates, and "Holy Haleakala!"s (61, to be exact, plus this one to make 62). I […]
