Chandra Sky Map - Joe DePasquale runs through the process of creating the map and some helpful tips for using the interactive tool.
Fomalhaut is a magnitude 1.16 star in the "Piscis Austrinis" or "Southen Fish," and one of the first stars discovered with an extrasolar planet (previously). It has been dubbed "The Eye of Sauron" after a stunning picture taken in 2008 of its debris ring. There was some controversy about the exoplanet, dubbed "Fomalhaut b" though as it turns out, its orbit is stranger than expected.
Well now, this is an interesting discovery... Reexamination of data collect through HARPS has resulted in finding three additional planets bringing the total to six. One of which is safely within the goldilocks zone of its star.
NASAs Kepler mission has discovered over 1,100 extrasolar planet candidates. Including, "68 Earth-sized, 288 super-Earth-sized, 662 Neptune-sized, and 165 Jupiter-sized planets". 54 are found in their star's habitable zone, with five of those considered "near-Earth sized" [more inside]
Amid news of new extrasolar planet discoveries, including a system with a possible 7 planets, Greg Laughlin and Sam Arbesman have released a paper that will be published next month in the open-access journal PLoS One. "A Scientometric Prediction of the Discovery of the First Potentially Habitable Planet with a Mass Similar to Earth" (pdf of full paper) boldly predicts that: "the first potentially habitable planet will be discovered, in this case, as early as May 2011, and likely by the end of 2013." NASA's Kepler mission is set to release data on hundreds of candidate planets early next year. The mission has discovered 7 so far. (Pre-vio-usly)
Scientists at NASA will announce the first findings from the Kepler mission next month. The results have caught scientists off-guard but they aren't giving any hints as to what mission co-investigator David Latham "was not prescient enough to anticipate". [more inside]
Scientists have discovered a planet composed of scorching hot ice. Originally thought to be a gas giant due to its mass, its actually only four times the size of Earth and most likely composed of exotic forms of ice, such as Ice VII and Ice X with s surface temperature of 300° C.
