Solar System Tour: The Sun
Everyone knows about the sun, it’s that really bright thing that rises every morning and sets every evening. Not everyone knows much about it though. For example, did you know the sun is actually a star? Ok, so maybe you knew that. But if you’re so smart, what’s it made of? The sun is almost entirely hydrogen, with a bit of helium mixed in and a tiny amount of all …

Rings around the Earth – Implications
Last week I posted a video that speculates what it would look like if the Earth had rings like Saturn. Well, over at Quantum Rocketry, Joe Shoer has two excellent follow-up posts.

Hubble Servicing Mission Pictures
Last weekend, NASA astronauts rendezvoused with the Hubble space telescope and repaired and upgraded the observatory in a series of five extremely challenging spacewalks. Their mission is now accomplished, Hubble has been set free to continue orbiting and doing cutting edge science, and the shuttle will be landing tomorrow morning. On Monday, the Big Picture had an awesome series of photos of the launch and the mission. And if that’s …

In a little over five hours from now, seven astronauts will be blasted into space for the final Hubble repair mission. I could write all about it, but Mike Brown posted a wonderful entry about the mission, so I will just post a teaser and direct you to his blog, Mike Brown’s Planets: This week, for the sake of astronomy, seven people will strap themselves on to the top of …
