“The Kepler and K2 missions just keep on giving!” Harvard astrophysicist, David Latham told The Daily Galaxy. “Operations ended more than three years ago when the spacecraft ran out of fuel, but we continue to mine the data archives for celestial gems.”
On February 5, 2019, The Galaxy reported that if advanced, space-faring alien life exist anywhere in the Milky Way, odds are they will live in the Galactic Habitable Zone (GHZ). And if they want to explore the Milky Way searching for other life-bearing planets, similar to Earth, they would only have to explore the GHZ, not the whole of the Galaxy.
Astronomers believe that a catastrophic collision stripped off the silicate mantle, leaving only the 70 percent iron core of the two exoplanets that exist in the newly discovered Kepler 107 star system. The two alien objects have almost identical radii of 1.5 and 1.6 Earth radii, but have widely disparate densities.
