For the first time, the Chandra X-ray Observatory has detected an exoplanet eclipsing its star. Having x-rays of a planet gives greater insight into its properties. The planet, which is 63 lightyears away, is over 30 times closer to its star than we are to our sun and completes its orbit in only 2.2 Earth days.

The porpoise galaxy used to be a spiral galaxy until it drifted too close to the elliptical galaxy seen under it, and then got pulled apart. Some see the pair as a penguin with an egg, but I also think it looks a bit like a hummingbird. What do you see?

Over 100 years ago, Albert Einstein first predicted the existence of gravitational waves. Essentially, gravitational waves are ripples in the space-time continuum caused by major events in the cosmos, such as a supernova explosion. These newfound results show that Einstein may have been right all along. The data could be used to create better detectors for gravitational waves, and also sets the stage to improve our knowledge about the Universe.

"Since, in the long run, every planetary society will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring — not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive." - Carl Sagan More information about PHAs and a larger version of the image here: http://1.usa.gov/1c71Dob
This week on StarTalk radio: Dark Matter and Dark Energy If dark matter is the longest unsolved problem in astrophysics, how can Neil deGrasse Tyson answer your Cosmic Queries this week? Well, it turns out we do know something about the stuff that makes up 96% of our universe. For instance, how it affects the rotation of galaxies, and what would happen if it disappeared. And whether dark matter is increasing as the universe expands. You’ll find out if there are connections between black holes and dark matter and what Hawking Radiation is. Did the recent experiments on the ISS explain why dark matter doesn’t interact with ordinary matter? Plus, Neil tells comic co-host Leighann Lord why he thinks dark energy should be named Fred.
