Scientists report the existence of 15 new planets -- including one 'super-Earth' that could harbor liquid water -- orbiting small, cool stars near our solar system.
Our galaxy could have 100 billion brown dwarfs or more according to a recent survey of dense star clusters
Astronomers have confirmed the existence of the seventh planet around the ultracool dwarf star TRAPPIST-1.
A team of scientists reports that it has discovered the existence of a white dwarf star whose atmosphere is rich in carbon and nitrogen, oxygen and hydrogen. The white dwarf is approximately 200 light years from Earth and is located in the constellation Boötes.
Two red dwarfs and their accompanying gas giant were discovered through a microlensing event -- but their true nature could only be confirmed by Hubble.
Currently the best place to search for life beyond the solar system. TRAPPIST-1 is an ultracool dwarf star -- it is much cooler and redder than the Sun and barely larger than Jupiter.
