NASA’s Tally of Planets Outside Our Solar System Reaches 6,000 – NASA

It’s been 30 years since the discovery of the first planet around another star like our Sun. With every new discovery, scientists move closer to answering whether there are other planets like Earth that could host life as we know it. NASA/JPL-Caltech The milestone highlights the accelerating rate of discoveries, just over three decades since … Read more

Astronomers Map Stellar ‘Polka Dots’ Using NASA’s TESS, Kepler – NASA Science

Scientists have devised a new method for mapping the spottiness of distant stars by using observations from NASA missions of orbiting planets crossing their stars’ faces. The model builds on a technique researchers have used for decades to study star spots. By improving astronomers’ understanding of spotty stars, the new model — called StarryStarryProcess — … Read more

NASA Data Reveals Possible Reason Some Exoplanets Are Shrinking – NASA

A new study could explain the ‘missing’ exoplanets between super-Earths and sub-Neptunes. Some exoplanets seem to be losing their atmospheres and shrinking. In a new study using NASA’s retired Kepler Space Telescope, astronomers find evidence of a possible cause: The cores of these planets are pushing away their atmospheres from the inside out. Exoplanets (planets … Read more

Scorching, Seven-Planet System Revealed by New Kepler Exoplanet List – NASA

A system of seven sweltering planets has been revealed by continued study of data from NASA’s retired Kepler space telescope: Each one is bathed in more radiant heat from their host star per area than any planet in our solar system. Also unlike any of our immediate neighbors, all seven planets in this system, named … Read more

Why NASA’s Roman Mission Will Study Milky Way’s Flickering Lights – NASA

NASA’s Nancy Grace Roman Space Telescope will provide one of the deepest-ever views into the heart of our Milky Way galaxy. The mission will monitor hundreds of millions of stars in search of tell-tale flickers that betray the presence of planets, distant stars, small icy objects that haunt the outskirts of our solar system, isolated … Read more
