Hubble Finds Appearances can be Deceptive
Baltimore MD (SPX) Jan 30, 2013
Globular clusters are roughly spherical collections of extremely old stars, and around 150 of them are scattered around our galaxy. Hubble is one of the best telescopes for studying these, as its extremely high resolution lets astronomers see individual stars, even in the crowded core. The clusters all look very similar, and in Hubble's images it can be quite hard to tell them apart - and they all look much like NGC 411, pictured here. And yet appearances can be deceptive: NGC 411 is in fact ... read more
