Neptune-sized Planet Found Around a Baby Star 32 Light-years Away

Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) and data from the now-retired Spitzer Space Telescope  have announced the discovery of a Neptune-sized exoplanet orbiting AU Microscopii (AU Mic for short), a red M-dwarf star 31.93 light-years away and only about 20 to 30 million years old. The star is so young that it’s still…

Seven Earth-sized Exoplanets Discovered Around a Single Nearby Star!

In what’s being called a “record-breaking exoplanet discovery” NASA announced today the detection of not one, not two, not three or four but seven exoplanets orbiting the ultra-cool dwarf star TRAPPIST-1, located just under 40 light-years away in the constellation Aquarius.

The ring is so…
