Slightly closer to home, at least in our own galaxy, another study also published in Nature looks at a single red dwarf star
in a way that is a step forward in astronomers' search for life beyond Earth.
Objects in space that have just a little more mass than brown dwarfs are called red dwarf stars
. Red dwarfs may not be much larger than brown dwarfs, but that small increase in size makes a big difference.

Hattie Hayridge is the main attraction.
One of the 15 newly discovered planets was found orbiting one of the brightest red dwarf stars
, called K2-155, located about 200 light years away from Earth.

give off less energy than other stars do so they might not emit enough energy to keep planets in the traditional habitable zone warm enough.
Red dwarf stars
are smaller, cooler, and fainter than our Sun.

Two Princeton researchers recently contemplated that we really might be alone in the universe, but the study of red dwarf stars
in the Milky Way discovered nine super-Earths - and two in the 'habitable zone' where liquid water could exist.
The PHL pointed the telescope toward Ross 128 while observing a whole group of red dwarf stars
- smaller, cooler and less luminous than our sun.
This first direct estimate of the number of light planets around red dwarf stars
has just been announced by an international team using observations with the HARPS spectrograph on the 3.6-meter telescope at ESO's La Silla Observatory in Chile.
A radio telescope at the Arecibo Observatory in Puerto Rico picked them up on May 12 while checking out red dwarf stars
that have planets orbiting them, as part of a project to learn more about the "radiation and magnetic environments around the stars or even hint the presence of new sub-stellar objects, including planets."
