A huge part of the Solar System is just made of ice. There are comets, rings, moons and even dwarf planets. Where did all this ice come from, and what impact (pardon the pun) has it had for life on Earth?

UT writer Steve Nerlich and I have collaborated for a couple of podcasts on the 365 Days of Astronomy podcast series where we talk about our favorite space shuttle missions. We actually did the first one last year, and decided to do an encore this year with the end of the space shuttle program upon us. Give us some love and have a listen:
My Favorite Space Shuttle Missions, Part 1
My Favorite Space Shuttle Missions — Part 2
And if anyone is interested in doing their own podcast on 365 Days of Astronomy and sharing your interests in space and astronomy, there are plenty of days available throughout the rest of the year. Find out more at this link.
Most people know how to find two constellations: the Big Dipper, and Orion the Hunter. You can teach a small child to find Orion, and at the right time of year, they’ll find it in seconds. There’s so much going on in this spectacular constellation, from the star formation in the Orion Nebula to mighty red supergiant Betelgeuse, ready to explode. Let’s learn about the history and science of the constellation Orion.

Spacevidcast’s Jason Rhian had a chance to go behind the scenes with the Google Lunar X PRIZE team Omega Envoy to take a peek at their new facility and the progress of their lunar rover. Omega Envoy is one of nearly 30 teams competing to win part of the $30 million dollar pot for sending a rover to the moon and completing specific tasks.

The Earth seems like a safe place, most of the time. But we have evidence of terrible catastrophes in the ancient past, times when almost all life on Earth was wiped out in a geologic instant. What could have caused so much devastation? And will something like this happen again?

The Sun, Moon, stars and planets are visible to the unaided eye, and so they have been visible to astronomers since before recorded history. Some of the earliest records we do have tell us what the ancient astronomers thought about the heavens, and how they used the changing night sky in their daily lives.

Just as sound can echo off distant objects, light can echo too. And the echoes of light bouncing off stellar remnants, black hole accretion disks, and clouds of gas and dust provide astronomers with another method of probing the distant cosmos.

Have you ever wanted to go to space, but lacked the… everything… to be an astronaut? A whole new industry of space tourism will take you where you need to go. There are new companies offering zero-G flights, sub-orbital flights, and there have even been paying customers who have gone into orbit. Is this going to be space travel for the rest of us?

It’s now believed that there’s a supermassive black hole lurking at the heart of every galaxy in the Universe. These monstrous black holes can contain hundreds of millions of times the mass of our own Sun, with event horizons better than the Solar System. They’re the source of the most energetic particles in the Universe, the brightest objects in the Universe, and the place where the laws of physics go to get mangled.

The in previous podcast, we talked about the old way navigators used to find their way around the planet; by looking at objects in the sky, and doing some tricky math. The new navigation system, of course, is the Global Positioning System, and it helps you find your spot on the planet with amazing accuracy. Let’s see where the system came from, and how it works.
