The count of confirmed exoplanets just ticked past the 5,000 mark, representing a 30-year journey of discovery led by NASA space telescopes.
PASADENA, Calif. (NASA PR) — Not so long ago, we lived in a universe with only a small number of known planets, all of them orbiting our Sun. But a new raft of discoveries marks a scientific high point: More than 5,000 planets are now confirmed to exist beyond our solar system.
MOFFETT FIELD, Calif. (NASA PR) — Scientists recently added a whopping 301 newly validated exoplanets to the total exoplanet tally. The throng of planets is the latest to join the 4,569 already validated planets orbiting a multitude of distant stars. How did scientists discover such a huge number of planets, seemingly all at once? The answer lies with a new deep neural network called ExoMiner.
WASHINGTON (NASA PR) — In 2020, NASA made significant progress on America’s Moon to Mars exploration strategy, met mission objectives for the Artemis program, achieved significant scientific advancements to benefit humanity, and returned human spaceflight capabilities to the United States, all while agency teams acted quickly to assist the national COVID-19 response.
MOUNTAIN VIEW, Calif. (SETI Institute PR) – Thanks to new research using data from the Kepler space telescope, it’s estimated that there could be as many as 300 million potentially habitable planets in our galaxy. Some could even be pretty close, with several likely within 30 light-years of our Sun. The findings will be published in The Astronomical Journal, and research was a collaboration of scientists from NASA, the SETI Institute, and other organizations worldwide.
TEMPE, Ariz. (Arizona State University PR) — As missions like NASA’s Hubble Space Telescope, TESS and Kepler continue to provide insights into the properties of exoplanets (planets around other stars), scientists are increasingly able to piece together what these planets look like, what they are made of and if they could be habitable or even inhabited.
The star Kepler-160 and its companion KOI-456.04 are more reminiscent of the Sun-Earth system than any previously known exoplanet-star pair
Göttingen, Germany (Max Planck Institute PR) — The star Kepler-160 is probably orbited by a planet less than twice the size of the Earth with a star-planet distance that could permit planetary surface temperatures conducive to life. The newly discovered exoplanet, which was found by a team of scientists led by the Max Planck Institute for Solar System Research (MPS) in Göttingen is more than just another potentially habitable world.
MOUNTAIN VIEW, Calif. (SETI Institute PR) — In a new paper published in the Astrophysical Journal Letters, co-authored by SETI Institute scientist Jeff Coughlin, astronomers using Kepler data have identified a planet nearly the same size of Earth that orbits in its star’s habitable zone, where liquid water could exist on its surface.
This new world, Kepler-1649c, is 300 light-years away and orbits a star that is about one-fourth the size of our Sun. Only 6% bigger than the Earth, it shares its sun with a planet much like Venus, Kepler-1649b, which was discovered three years ago. Although NASA’s Kepler space telescope was retired in 2018 when it ran out of fuel, scientists are still making discoveries as they continue to examine the signals Kepler detected.
MOFFETT FIELD, Calif. (NASA PR) — A team of transatlantic scientists, using reanalyzed data from NASA’s Kepler space telescope, has discovered an Earth-size exoplanet orbiting in its star’s habitable zone, the area around a star where a rocky planet could support liquid water.
