Space and astronomy news
It’s a great idea, so all the missions might as well join in. Earlier today, Ian reported on how the Lunar Reconnaissance Orbiter mission is offering the chance for the public to ‘ride along’ to the moon by sending their names to be added to a computer chip which will be embedded on the spacecraft. …

As you’re probably aware, NASA has a lot of robotic explorers out there in space, and even more the works here on Earth. I was actually surprised to learn that they have 53 mission already in operation, and another 41 missions in development. But with the human exploration of the Moon charging forward, the robotic …
While finding a planet orbiting another star is incredibly exciting, it’s almost becoming commonplace. The current exoplanet count is up to 270. So now that astronomers know where these exoplanets are located, they are currently devising new techniques in order to study the planets in detail. Using a new method similar to how polarized sunglasses …
Here’s what’s going around the astrosphere. First, I’d like to remind you that the 5th Carnival of Space is happening tomorrow. Get your entries in! Spacescan has some interesting details on India’s plans to send a mission to the Moon. The Astroprof spoke with Mars Society’s Bob Zubrin about going directly to Mars. Pamela Gay …
Astronomers have directly imaged a brown dwarf companion to the star HD 3651. This star is already known to host an extrasolar planet – less massive than Saturn, but sitting within the orbit of Mercury. HD 3651 is slightly less massive than the Sun, and is located 36 light-years away in the constellation Pisces. The …
Like shards of shattered glass caught in a spotlight, the stars appear deceptively passive in the night sky. Yet, each one is an object of extraordinary ferocity. Stellar surface temperatures can reach 50,000 degrees Celsius- over ten times hotter than our Sun – and on a few it can reach over one million degrees! The …

An international team of astronomers have turned up two new Jupiter-sized planets orbiting distant stars. These planets are incredibly close to their parent stars; just a fraction of the distance from Mercury to the Sun. Astronomers believe these planets are being eroded by the intense radiation of their stars. The discovery was made using the …
A network of amateur astronomers has discovered an extrasolar planet located 500 light years away. This incredible discovery was made using a technique that measures the brightness of thousands of stars, watching for a periodic dimming. In this case, the Jupiter-sized planet, TrES-2, orbits its host star every 2.5 days, dimming it by 1.5%. Although …

Astronomers have turned up plenty of extrasolar planets, but a newly discovered binary pair of planets is quite the find. The system consists of a 7-Jupiter mass planet and a 14-Jupiter mass planet… but no star. These planets – or “planemos” – just orbit each other. Their discovery challenges the current theory that planets are …
