Happy Valentine’s Day with Diamonds in the Sky…

The biggest diamond ever known was found by a team of scientists from the Harvard-Smithsonian Center for Astrophysics. Indeed, the diamond is the core of a crystallized WD (White-Dwarf type) star called BPM 37093 that is located 50 light-years from Earth in Centaurus constellation. The core is about 2500 miles wide and can make a diamond with 10 billion trillion trillion carats. For some time scientists have believed that cooling WD stars should have a crystallized cores. In the case of BPM 37093 that is also a pulsating star, it is possible to calculate the core size by measuring the space between radial overtone modes. The size of the diamond core is in turn the lead to determine the age of the star and somehow the age of the galaxy. Coordinates are R.A. (J2000) = 12 38 50.3, Dec. (J2000) = -49 48 00, mv = 13.5, mb=14.1. Anyone interested?
