Taking advantage of a total lunar eclipse, astronomers used Hubble to simulate how astronomers can search for evidence of life beyond Earth by observing potential "biosignatures" on exoplanets. A team of scientists led by the Carnegie Institution for Science has released the largest collection of observations for hunting exoplanets to the public.

"With red dwarfs almost everywhere around our galaxy, and these small, potentially habitable and rocky planets around them, the chance one of them isn't too different than our Earth looks a bit brighter," he said.The new study was published Wednesday in The Astrophysical Journal Letters. A star among planet hunters, Natalie Batalha wields a formidable weapon: NASA’s Kepler space telescope. University of Warwick researchers have identified a white dwarf pulsar – a star type which has eluded astronomers for half a century. By Hannah Morrison Newsbeat reporter. Exoplanet HIP 67522 b is located only 490 light-years away from earth. TESS is now in an extended mission.

Disha Kandpal On July 4, NASA’s Transiting Exoplanet Survey Satellite (TESS) finished its primary mission, imaging about 75% of the starry sky and finding 66 new exoplanets. Astronomers have discovered a planet nearly the same size as Earth that orbits in its star’s habitable zone, where liquid water could exist on its surface, a new study said. The massive size of this planet strongly indicates, that like our Jupiter, exoplanet HIP 67522 b is also a gas giant.HIP 67522 b was identified as a planet candidate by NASA's Transiting Exoplanet Survey Satellite (TESS). According to NASA, this planet appears to be the youngest hot Jupiter ever found.

The co-lead of NASA’s Kepler space telescope, Jessie Dotson, has pursued asteroids and exoplanets, and a lot more besides. New research suggests that aging stars can warm previously frozen Hoth-like planets into supporting life. NASA’s Transiting Exoplanet Survey Satellite (TESS), which will scan the skies to look for planets beyond our solar system—known as exoplanets—is now in Florida to begin preparations for launch in April. This set of travel posters envision a day when the creativity of scientists and engineers will allow us to do things we can only dream of now. NASA described it as the "most similar to Earth in size and estimated temperature" out of the thousands of exoplanets discovered by Kepler. The flying SOFIA telescope has found a planetary system that has similar architecture to our own, in the system Epsilon Eridani. How did we get here? Discovery: 95 new planets! Members of the public can help scientists learn how planets form by sifting through data from NASA's WISE mission, managed by the agency's Jet Propulsion Laboratory.

Hubble reveals that at least three of the TRAPPIST-1 planets do not seem to contain puffy, hydrogen-rich atmospheres similar to gaseous planets such as Neptune.

A new study published on NASA’s official website has reported the detection of an exoplanet. Aaron revealed to a science portal that we can learn a lot about our solar system and how it came to be, by studying these exoplanets.

The knowledge and tools NASA has developed to study life on Earth will be a great asset to the study of planets beyond our solar system. NASA's Spitzer Space Telescope finds new clues. The Jupiter like planet takes only seven days to orbit its star, which has almost the same mass as our Sun. "The more data we get, the more signs we see pointing to the notion that potentially habitable and Earth-size exoplanets are common around these kinds of stars," said study lead author Andrew Vanderburg, a researcher at the University of Texas at Austin.

NASA's efforts in digital communications have been recognized with nominations for six Webby Awards, the highest honor for online communications. How do stars and planets come into being? They include a new planet orbiting a very bright star– the brightest star ever discovered … Also, what's a light-year anyway? "This intriguing, distant world gives us even greater hope that a second Earth lies among the stars, waiting to be found,” said Thomas Zurbuchen, associate administrator of NASA’s science mission directorate in Washington, D.C.Although NASA said that there are other exoplanets estimated to be closer to Earth in size – and others may be closer to Earth in temperature – there is no other exoplanet that's closer to Earth in both of these values that also lies in the habitable zone of its system.This newly revealed world is only 1.06 times larger than our own planet. The seven Earth-size planets of TRAPPIST-1 are all mostly made of rock, with some having the potential to hold more water than Earth, according to a new study published in the journal Astronomy and Astrophysics. New results from the 229th American Astronomical Society meeting reveal that Earth-sized planets can be made of minerals that are distinctly not Earth-like. Go here for the latest news and discoveries from NASA’s new mission to search for new worlds around 200,000 of the brightest stars near the Sun. A young star's stellar outburst brings its water snow line into view. Astronomers have discovered a planet nearly the same size as Earth that orbits in its star’s habitable zone, where liquid water could exist on its surface, a new study said.The presence of liquid water also indicates the planet could support life. It could look something like a large, newly discovered gas giant that takes about 20 years to orbit a star 11 light-years away from Earth; the discovery of this world, and confirmation of a sister planet, makes this the closest known multi-planet system to our own. Astronomers have discovered two planets using NASA's Kepler telescope: a super Earth inferno and its Neptune-like companion. Finding potential life-bearing worlds among the stars is NASA's next big challenge.
