Exoplanets near red dwarfs suggest another Earth nearer The nearest habitable, Earth-sized planet could be just 13 light-years away, research suggests. An analysis of small, dim "red dwarf" stars - which make up a majority of stars in our galaxy - shows that 6% of them host such a planet....

Title: The M Dwarf Problem in the Galaxy Authors: Vincent M. Woolf, Andrew A. West We present evidence that there is an M dwarf problem similar to the previously identified G dwarf and K dwarf problems: the number of low-metallicity M dwarfs is not sufficient to match simple closed-box models of loca...

After decades of searching, astronomers discovered the first definite brown dwarf only ten years ago. Now, a new analysis of Hubble Space Telescope data implies our Galaxy has almost as many of these failed stars as it does normal stars like the Sun.
The Sun and most other stars power themselves by...
