Alien Worlds: How Common Are Habitable Planets?
2013-11-05 02:51:36

[ Watch the Video: Earth May Not Be So Unique After All ] redOrbit Staff & Wire Reports - Your Universe Online New statistical analysis of data obtained by NASA’s now-retired Kepler spacecraft has revealed that one out of every five sun-like stars have at least one Earth-sized planet in the habitable zone. “What this means is, when you look up at the thousands of stars in the night sky, the nearest sun-like star with an Earth-size planet in its habitable zone is probably only...

Scientists Meet To Discuss 833 New Exoplanets
2013-11-04 16:21:02

Lee Rannals for redOrbit.com - Your Universe Online An international group of scientists are gathering for the second Kepler Science Conference this week at NASA’s Ames Research Center in Moffett Field, California. Researchers will be discussing the latest findings from the Kepler Space Telescope data, which includes the discovery of 833 new candidate planets. Ten of the new exoplanets are less than twice the size of Earth and orbit in the habitable zone. New Kepler data shows that...

NASA will video stream a news briefing at 10:15 a.m. PST (1:15 p.m. EST) Monday, Nov. 4, to announce new results from the agency's Kepler mission. The briefing, taking place during the Kepler Science Conference, will be in building 152 at NASA Research Park in Moffett Field, Calif. With its 2009 launch, Kepler became the first NASA mission capable of finding Earth-sized planets in or near the habitable zone -- the region around a star in which orbiting planets may have surface temperatures...

Exoplanets With Too Much Carbon Are Most Likely Waterless
2013-10-26 04:14:31

redOrbit Staff & Wire Reports - Your Universe Online Diamond planets and other worlds that are rich in carbon might be waterless, NASA researchers explained earlier this month at the 45th meeting of the American Astronomical Society Division of Planetary Sciences in Denver. Torrence Johnson, a Senior Research Scientist at the Jet Propulsion Laboratory (JPL) in Pasadena, California, and his colleagues explain that since our sun is a carbon-poor star, the Earth is a planet that is...

Astronomers Discover Seventh Planet Orbiting Nearby Star System
2013-10-25 15:26:17

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have discovered a seventh planet orbiting a dwarf star, known as KIC 11442793, making it the first Kepler planetary system with this many alien worlds. The star is about 2,500 light years from Earth and its planetary system could be a record holder. All seven planets in the system orbit much closer to their host star, meaning the system is very crowded when compared to even our own Solar System. Scientists say that the...

More Than 1,000 Exoplanets Have Been Discovered Since 1992
2013-10-25 14:17:10

Lee Rannals for redOrbit.com - Your Universe Online The search for extra-terrestrial planets has been ongoing for at least the past 21 years. Since the early days of exoplanet hunting, the number of such planets identified by scientists has pushed beyond a thousand, thanks largely to the advent of high-tech space observatories, such as the Kepler Space Telescope. Exoplanets, or alien planets, are those planets that exist outside of our Solar System. So far, scientists have discovered...

Sun Intensity Will End Life On Earth In No More Than 3.25 Billion Years
2013-09-19 10:33:04

[ Watch the Video: Earth Will Enter The Hot Zone In Several Billion Years ] Brett Smith for redOrbit.com - Your Universe Online In one of the longest range weather forecasts ever made, a team of UK scientists has determined that the sun’s growing intensity will lead to the evaporation of the oceans and end of life on Earth in about 1.8 to 3.2 billion years – according to a new report published in the journal Astrobiology. Using planets outside the Solar System and their stars as...

Exoplanet With Water-Rich Atmosphere
2013-09-06 07:43:41

John P. Millis, PhD for redOrbit.com - Your Universe Online The search for a habitable planet beyond Earth is on. Scientists have been searching the heavens to find an exoplanet that is just the right distance from its host star to support liquid water, all the while targeting a surface gravity we would be familiar with and an atmosphere oozing with oxygen. Such a planet has not yet been found, but progress has been made, and we continue to find smaller and smaller planets closer to the...

Exoplanet Discovered That Makes Full Orbit In Under Nine Hours
2013-08-19 09:55:32

Lee Rannals for redOrbit.com - Your Universe Online Scientists from MIT have discovered an exoplanet 700 light-years away that fully orbits its host star every 8.5 hours. The scientists wrote in The Astrophysical Journal the earth-sized planet, Kepler 78b, has one of the shortest orbital periods ever detected. They have estimated its surface temperatures may reach more than 5,000 degrees Fahrenheit due to its extremely close orbital position. Kepler 78b is so close to its star the...
