Here are some pics of most earth-like exoplanets uploaded by NASA: Gliese 667Cc, 22 light-years from Earth, is 4.5 times Earth's mass, orbits its cooler red dwarf star in 28 days, and likely resides ...

The planet 51 Pegasi b is a long way from Prior Lake, 48 light years (several billion miles) to be exact. It orbits a fifth magnitude star, similar to our Sun, in the constellation Pegasus. It was ...

By then, the primary system consisted of three planets, namely Kepler-138b, c and d. Subsequent studies using Hubble and Spitzer instruments, conducted by NASA, showed that c and d are composed of ...

Her current focus is the Transiting Exoplanet Survey Satellite (TESS), an MIT-led NASA space telescope launched last year. Like Kepler, TESS looks for a slight dimming in the luminosity of a star ...

Astronomers have identified a fourth exoplanet, Kepler-51e, in the Kepler-51 star system using the James Webb Space Telescope ...

Previous observations led by astronomer Emily Leiner using NASA's retired Kepler space telescope had revealed that all of M67's 500 stellar residents are about four billion years old, save for a ...

The star's high spin rate was discovered with NASA's retired Kepler space telescope. While normal Sun-like stars typically take about 30 days to complete one rotation, the lurker takes only four days.

A Triple Star System Yields an Unusual Surviving Star Unlike our Sun, which exists alone, at least half of the stars in our ...
