Astronomers say one in five sun-like stars likely to have habitable planets

By - November 5, 2013 7 Pictures
Bookmakers may be revising their odds on the question of us being alone in the Universe after scientists revealed that our galaxy could hold billions of habitable worlds. University of California Berkeley and University of Hawaii (UH) astronomers carried out a study using data from NASA’s Kepler space telescope to provide part of the answer to the question, “How many of the 200 billion stars in our galaxy have potentially habitable planets?” The answer they got back was that one in five sun-like stars may have Earth-size planets that could support life.

Kepler finds clouds on extrasolar planet

By - October 1, 2013 2 Pictures
"How's the weather?" has just become a topic of interstellar conversation. Using data from NASA's Kepler and Spitzer space telescopes, astronomers have mapped the first clouds discovered on an extrasolar planet. Not only does this technique give us an interesting bit of pure science, it could also be applied in the search for more earth-like planets according to NASA. Read More

MIT finds exoplanet with an 8.5-hour year

By - August 20, 2013 8 Pictures
Sometimes it seems as if the year just flies by. On planet Kepler 78b, it does exactly that. According to a team of scientists at MIT, the extrasolar world is so close to its sun that its year is only 8.5 hours long. That means that not only could a person go through almost three birthdays in one day, but that the surface temperature would be like taking up residence in a blast furnace. Read More

NASA abandons Kepler repairs, looks to the future

By - August 16, 2013 14 Pictures
If NASA has anything to say about it, Kepler is down, but not out. At a press teleconference on Thursday it announced that it has abandoned efforts to repair the damaged unmanned probe, which was designed to search for extrasolar planets and is no longer steady enough to continue its hunt. But the space agency is looking into alternative missions for the spacecraft based on its remaining capabilities. Read More

Scientists propose using gravity microlensing to keep Kepler in the hunt

By - June 19, 2013 5 Pictures
Last month, NASA declared its Kepler mission to hunt exoplanets at an end when one of the space telescope’s reaction wheels failed. Unable to keep itself pointed in the right direction, it could no longer carry on its hunt for planets beyond the Solar System. That seemed like the end of things, but Keith Horne of the University of St Andrews and Andrew Gould of Ohio State University disagree. They claim that Kepler could still hunt for exoplanets using gravity microlensing to detect how stars with planets distort space. Read More

"Einstein's planet" becomes first exoplanet discovered using new detection method

By - May 14, 2013 2 Pictures
Due to their relative faintness compared to their parent stars, most known exoplanets have been discovered using indirect detection methods – that is, detecting the effects they have rather than observing them directly. There are numerous indirect methods that have proven useful in the detection of exoplanets and now yet another, which relies on Einstein’s special theory of relativity, has joined the list with the discovery of an exoplanet known as Kepler-76b.

Scientists say at least one in six stars has an Earth-sized planet

By - January 13, 2013 2 Pictures
The latest analysis of data coming from NASA's Kepler telescope has revealed that nearly all the Sun-like stars in our galaxy appear to have planets orbiting them, and that at least 17 percent of them – about one in six – are hosting a planet the size of our own in close orbit. Because the Milky Way is estimated to contain some 100 billion stars, this means that our galaxy alone could have at least 17 billion Earth-sized planets, some of which may harbor the conditions for life.
