A new NASA planet-hunting spacecraft called TESS, which began science operations as Kepler was winding down, will give us thousands of new discoveries in…
Astronomers have found strong evidence of a frigid alien world about 3.2 times more massive than Earth circling Barnard's Star, the dim red dwarf that…
NASA's successor to the Kepler mission, the Transiting Exoplanet Survey Satellite (TESS), is already paying dividends. The satellite was only launched in April and spent…
NASA has announced that it officially activated its latest exoplanet-hunting spacecraft TESS (Transiting Exoplanet Survey Satellite) on July 25th. According to the NASA release, TESS…
How do we spot something as tiny and faint as a planet trillions of miles away? The trick is to look at the star!…
NASA's Transiting Exoplanet Survey Satellite - TESS - will fly in an orbit that completes two circuits around Earth every time the Moon orbits…
NASA is set to launch the Transition Exoplanet Survey Satellite (TESS) telescope into space in about two weeks. The space telescope will use the…
Theoretical physicist Michio Kaku doesn't just hope that humanity finds its way onto other planets... he's even picked out the ones we should be moving…
A new study has found that the seven planets orbiting the nearby ultra-cool dwarf star TRAPPIST-1 are all made mostly of rock, and some could…
New observations, when combined with very sophisticated analysis, have now yielded good estimates of the densities of all seven of the Earth-sized planets and suggest…
Hubble reveals that at least the inner five planets do not seem to contain puffy, hydrogen-rich atmospheres similar to gaseous planets such as Neptune. This…
NASA’s Kepler space telescope was launched in 2009 and measured the brightness of 200,000 stars at unprecedented precision for over four years, with the prime…
NASA has been hunting for extrasolar planets for years using the Kepler Space Telescope. Recently, NASA teamed up with Google to try and work out…
Heather A. Knutson is a professor in the Division of Geological and Planetary Sciences at the California Institute of Technology. Her group is working on…
Dr. Natalie Batalha leads the science investigation effort for Kepler – NASA's first mission to find Earth-size planets beyond our solar system. Kepler is seeking…
Astrophysicist Lisa Kaltenegger is the director of the Carl Sagan Institute at Cornell University. In this talk, held at the American Museum of Natural History,…
This fall marks 20 years since NASA began continuously, global measurements of Earth’s life from space. NASA satellites measure all the plant life on land…
Find out what we know about TRAPPIST-1, the recently discovered red dwarf star with 7 Earth-sized exoplanets. Astrophysicist Emily Rice hosts, with co-host Chuck Nice,…
Recently, a team of astronomers discovered a planet that puzzles them – a pitch black planet that swallows all light. The mysterious planet called ‘WASP-12b’…
The NASA Kepler team has identified 219 new planet candidates, 10 of which are roughly Earth-size and within their star’s habitable zone, the region that…
