Through the looking glass: Observations from NASA's Kepler mission ended in 2018, but scientists are still pouring over what it recorded. That data can include information about new solar systems and ...

The unusual system of three “super puff” planets has at least one more planet, revealed by its gravitational tug on other planets An unusual planetary system with three known ultra-low density ...

Move over TRAPPIST-1 – there’s an exciting new planetary system in town. Meet Kepler-385, home to seven Super-Earths that were just discovered in existing data. Located about 4,670 light-years from ...

A team of researchers led by Bill Cochran of The University of Texas at Austin has used NASA’s Kepler spacecraft to discover an unusual multiple-planet system containing a super-Earth and two ...

For the first time, astronomers have spotted an exoplanet whose orbit is decaying around an aging star. The doomed world appears destined to spiral closer and closer to its expanding star until they ...

A team of astronomers has found the first transiting circumbinary multi-planet system: two planets orbiting around a pair of stars. This discovery shows that planetary systems can form and survive ...

Using data from NASA’s Kepler space telescope, a team of researchers, led by astronomers at San Diego State University, detected the new Neptune-to-Saturn-size planet orbiting between two previously ...

Artist’s concept showing two of the seven planets discovered orbiting a sun-like star. The system, called Kepler-385, was identified using data from NASA’s Kepler mission. Credit: NASA/Daniel Rutter ...

On Feb. 22, astronomers announced that the ultra-cool dwarf star, TRAPPIST-1, hosts a total of seven Earth-size planets that are likely rocky, a discovery made by NASA’s Spitzer Space Telescope in ...

And then there were two—maybe. Astronomers say they have found a second plausible candidate for a moon beyond our solar system, an exomoon, orbiting a world nearly 6,000 light-years from Earth. Called ...

The same team that recently discovered the possibly water-covered, life-supporting planet, Kepler 22b, two weeks ago announced the discovery of two more Earth-sized planets on Monday. Ars Technica's ...

This is an artist's rendition of the Kepler-35 planet system, in which a Saturn-size planet orbits a pair of stars. The larger star is similar to the size of the Sun, while the smaller star is 79 ...
