Since the first extra-solar planet was found in 1992, we've made some decent progress in exploring other worlds out there, and may even be zeroing in on that "other Earth."
It's 600 light years from Earth, orbits a star very similar to our Sun in a period of about 290 days, and has a diameter about two and a half times that of Earth. What is it? It's the NASA Kepler mission's most recent exciting confirmed discovery, the extrasolar-planet Kepler 22B.
Of all the questions in science, few have haunted humans as persistently as this: Are we alone? For more than 50 years, scientists have listened for a signal from intelligent life on other planets… and come up empty. Now, they're running short of money. Is it time to give up?
NASA's Kepler mission announces the results from its first four months of observations: 1235 possible planets around other stars!
Among the thousands of vivid and unique Earth-sized planets we have come to know through Science Fiction, NASA's Kepler mission has now given us our first real one: meet Kepler 10b.
It's been a little over a year since NASA's Kepler telescope was launched into space. It's mission: to stare unblinkingly at 156,000 stars in a patch of sky in the constellations Lyra and Cygnus on a quest to spot extrasolar planets transiting their stars. Results so far? As anticipated…astounding.
208 parties in 46 countries on eight continents celebrated Yuri Alexyevich Gagarin between April 6 and 12th of this year. Who is Yuri and why does he deserve such accolades?
For several years there has been a lot of buzz about the detection of extra-solar planets, or exoplanets: planets orbiting stars other than our Sun. However, due to the limits in technology and observational capabilities, to date only large, gas giant planets orbiting close to the stars (so called "Hot Jupiters") have been found, with a possible exception or two.
Artistic rendition of exoplanet Gilese 436 b, created in Celestia In the past fifteen years, the search for other Earths– and possibly life– outside our own solar system has taken off. As of May 2008, 293 extrasolar planets have been confirmed. Most of these planets are big, gas giants like our own Jupiter but new […]
