Submission + - Diamond Star 1 billion trillion trillion carats (bbc.co.uk)

tclas writes: The cosmic diamond is a chunk of crystallised carbon, 4,000 km across, some 50 light-years from the Earth in the constellation Centaurus.

It's the compressed heart of an old star that was once bright like our Sun but has since faded and shrunk.

Astronomers have decided to call the star "Lucy" after the Beatles song, Lucy in the Sky with Diamonds.

Giant Planet Nine Times the Mass of Jupiter Found 73

cremeglace writes "In the late 1990s, astronomers noticed a distinct warp in the disk of dust and gas orbiting a young star some 60 light-years from Earth. Now, using new analytical tools, researchers have discovered a giant planet lurking within the dusty haze. About nine times as massive as Jupiter and composed mainly of gas, the planet is only a few million years old, proving that such enormous planetary bodies can form rapidly." What's amazing about this is that the images taken of the star clearly show the planet first on one side of the star, and then the other, several years later.
