Interstellar Sleuths

by Invader Xan in Supernova Condensate

“Of course, this identification is simply wrong.” That one remark caused a subdued but audible commotion in the audience, and a handful of shocked responses to be posted on twitter. The remark in question had been made by Jacek Krełowski, … Continue reading →... Read more »

The Universe at the Speed of Light [Infographic]

by Jason Carr in Wired Cosmos

I try to stay active on Twitter so that I can keep up with what’s happening in the world of #astronomy and #science. I actually learn a great deal from many of those that I follow (one of the reasons I love Twitter). One astronomer that I learn from regularly is Dr. Michael Brown (@plutokiller). [...]...

On Software in Astronomy

by sarah in One Small Step

I’ve been giving some thought to software development in astronomy, which is a difficult topic. All astronomers agree that good data processing, and hence good software, is crucial to doing rigorous science. To interpret observational data, to translate electrons on a detector to scientific knowledge, requires a solid understanding of the instrument, the observing conditions, [...]... Read more »

How to spot exo-Earths...

by Invader Xan in Supernova Condensate

It seems like we’re not going to stop discovering new exoplanets anytime soon. Around one sixth of all exoplanets currently known can be observed transiting their star’s disk. Given that transits are precisely what NASA’s Kepler mission is going to spend the next three years looking for, that number is certainly set to increase over the coming months. But with exoplanet transits comes a unique opportunity to study them…... Read more »
