"In the quest for extraterrestrial biological signatures, the first stars we study should be white dwarfs," said Avi Loeb, theorist at the Harvard-Smithsonian Center for Astrophysics (CfA) and director of the Institute for Theory and Computation. Even dying stars could host planets with life - and if such life exists, we might be able to detect it within the next decade.
"A globular cluster might be the first place in which intelligent life is identified in our galaxy," observed Loeb's collague, Rosanne DiStefano at the CfA in January, 2016. Globular star clusters are extraordinary in almost every way. The globulars, which are found in the halo of a galaxy, contain considerably more stars than the less dense galactic, or open clusters, which are found in the disk. They're densely packed, holding a million stars in a ball only about 100 light-years across on average. They're old, dating back almost to the birth of the Milky Way. And according to new research, they also could be extraordinarily good places to look for space-faring civilizations, according to DiStefano.

In July 2003, Hubble helped make the astounding discovery of a planet called PSR B1620-26b, 2.5 times the mass of Jupiter, which ...
