Hubble Discovers two Exo-Planets Circling Red Dwarf

(CNN) — For a craft that was launched in 1990, Hubble  continues to provide us with awe-inspiring firsts. This time, In May, researchers discovered three Earth-like worlds orbiting an ultracool red dwarf star 40 light-years away.

Red dwarf stars are at the end of the range of what is classified as a star. These stars are half the temperature and a 10th the mass of the sun, so it was a first to find planets orbiting this star which also appeared to be in the "habitable zone" of the star, meaning liquid water could pool on their surfaces.
