For the first time, scientists have found a rocky planet with an atmosphere orbiting in a star’s habitable zone. Researchers from Harvard University say the Earth-like world has conditions similar to those on Earth.

The exoplanet, LHS 1140 b, is 48 light-years from Earth. It orbits a red dwarf star at a distance close enough for water to remain liquid, but far enough away that it would not boil.

the universe is estimated to be 93 BILLION light-years wide.

Only the part we can see. There's more.

Also, that measurement is 20 years old by now, so the current size should be 93 billion and 20 light years wide.

Isn't space expanding as well, and faster than light too? So it ought to be even more than 20.

The universe is. The above measurements are for the observable universe, which is how much we can see from earth.
