TESS, the Transiting Exoplanet Survey Satellite, is NASA's newest exoplanet mission. Led by MIT, TESS will find thousands of new planets orbiting nearby stars. During its two year survey, TESS will watch a wide variety...

The Hubble and Kepler space telescopes found evidence for what could be a giant moon accompanying a gas-giant planet that orbits the star Kepler-1625, located 8,000 light-years away in the constellation Cygnus. The moon may...

An international team of astronomers has reported what may be the first example of an intact planet closely orbiting a white dwarf, a dense leftover of a Sun-like star that’s only 40% bigger than Earth. The...

How do we spot something as tiny and faint as a planet trillions of miles away? The trick is to look at the star! So far, most of the exoplanets – worlds beyond our solar system – we’ve found were detected by looking for tiny...
