In 2004, astronomers discovered a star composed entirely of diamond, measuring 4,000 km across and 10 billion trillion trillion carats. 50 light years from Earth, the diamond star is classified as a crystallized white dwarf, the hot core that remains after a star burns out. Only recently have scientists been able to study the contents of the white dwarf, and they’ve confirmed that the crystallized carbon interior of the star is, in fact, the galaxy’s largest diamond.
Prominently barred spiral galaxy NGC 1073, pictured above, was captured in spectacular detail in this recently released image taken by the orbiting Hubble Space Telescope. Light takes about 55 million years to reach us from NGC 1073, which spans about 80,000 light years.
