Reflecting
I went for a drive up on a ridge to take some nightscapes while at the IceInSpace AstroCamp, when I noticed the stars reflecting off my (very dirty and dusty) car, so I decided to incorporate them into a selfie.

Turned out better than I'd hoped :)
Thanks for your +1's and shares.

Need to take a moment and remember how glorious things are?

I know, it's quite the day here in the States, so maybe you should take a few minutes and revel in the glory of the night sky as seen in "Helvetia's Dream", a fantastic time lapse video by Alessandro Della.

I have a description of some key moments at:

#BAFact: In about 4 billion years (give or take), the Milky Way will collide with the Andromeda galaxy.


The Andromeda Galaxy is the nearest big spiral galaxy to ours - in fact it's about the same size and mass as our Milky Way. The thing is, it's headed toward us! We've known that for a long time, but new results show that it's aimed more or less right at us, and in a few billion years our two huge galaxies will collide and possibly merge, forming one, even more monstrous galaxy. Some people refer to it as "Milkomeda". I think I like Andromaway better. If you've got a better name, feel free to suggest it!

[Before you ask, yes most galaxies in the Universe are moving away from us as the cosmos expands, but that's on a very, very large scale. Andromeda is quite close to us, so it's not as affected by the Universal expansion.]

Next time you take a photo with your smart phone, you can thank NASA for making that technology possible.

From here to infinity

Amateur astronomer Detlef Hartmann tackled a daunting task: using his home-made 44 cm telescope, observe the "empty" patch of sky Hubble looked at in the first Deep Field - an observation which revealed over 1500 galaxies and changed the way we look at the Universe.

The results are, simply, stunning. I show them side-by-side below, but go to my blog for an animated morphing GIF. I also wrote up the details (with links) and added more than a dash of personal philosophy. Enjoy.

ALPHA CENTAURI HAS AN EARTH-SIZED PLANET!

OK, pardon me for shouting, but I'm pretty excited. :) Alpha Centauri - the closest star system in the sky - has been found to harbor an Earth-sized planet. Alpha Cen is a triple star, with two fairly Sun-like stars orbiting each other, and a third red dwarf orbiting much farther out. The planet was found to orbit the cooler of the two stars in the binary.

The planet, called Alpha Centauri Bb, is only 1.13 tines the Earth's mass, making it one of the smallest exoplanets yet found. Unfortunately, it orbits the star so close in - just 6 million kilometers - that's it's baking hot. We won't be finding any life there we would recognize.

BUT, this means the technique used to find it works for lower-mass planets, making it hopeful we're close to finding an Earth-sized planet orbiting in its star's habitable zone.

I have the details on my blog:
