| NASA's Kepler mission announces a planet bonanza, 715 new worlds Posted: 26 Feb 2014 12:33 PM PST NASA's Kepler mission announced Wednesday the discovery of 715 new planets. These newly-verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system. Nearly 95 percent of these planets are smaller than Neptune, which is almost four times the size of Earth. This discovery marks a significant increase in the number of known small-sized planets more akin to Earth than previously identified exoplanets, which are planets outside our solar system. |
| 'Super-Earths' may be dead worlds: Being in habitable zone is not enough Posted: 26 Feb 2014 04:49 AM PST In the last 20 years the search for Earth-like planets around other stars has accelerated, with the launch of missions like the Kepler space telescope. Using these and observatories on the ground, astronomers have found numerous worlds that at first sight have similarities with the Earth. A few of these are even in the 'habitable zone' where the temperature is just right for water to be in liquid form and so are prime targets in the search for life elsewhere in the universe. New results suggest that for some of the recently discovered super-Earths, such as Kepler-62e and -62f, being in the habitable zone is not enough to make them habitats. |
| Water detected in a planet outside our solar system Posted: 25 Feb 2014 07:17 AM PST Water has been detected in the atmosphere of a planet outside our solar system with a new technique that could help researchers to learn how many planets with water, like Earth, exist throughout the universe. The team of scientists that made the discovery detected the water in the atmosphere of a planet as massive as Jupiter that is orbiting the nearby star tau Boötis. |
