Largest known structure in the universe is 1.4 billion light years long

Researchers confirm an exoplanet potentially capable of sustaining life. The planet has a mass six times that of Earth and orbits a star similar to our sun, located just 20 light years away.

100 years ago this week, Edwin Hubble announced his monumental discovery that the universe existed beyond our own Milky Way galaxy. He noted that the Andromeda nebula, also called M31, was nearly a million light years away – too remote to be a part of the Milky Way.
