Den ligger 4000 ljusår bort. Planetens omloppsbana är 600 000 kilometer i diameter. Den snurrar runt en kraftigt radioaktivt strålande neutronstjärna.

Men det som gör den speciell är att hela planeten är en enorm diamant, uppger nu en grupp astronomer från universiteten i Melbourne, Hawaii och Manchester. De har nämligen granskat den avlägsna himlakroppen, och studien publiceras nu i tidskriften Science.

An alien world blacker than coal, the darkest planet known, has been discovered in the galaxy.

The world in question is a giant the size of Jupiter known as TrES-2b. NASA’s Kepler spacecraft detected it lurking around the yellow sun-like star GSC 03549-02811 some 750 light years away in the direction of the constellation Draco.

”It’s just ridiculous how dark this planet is, how alien it is compared to anything we have in our solar system,” study lead-author David Kipping, an astronomer at the Harvard-Smithsonian Center for Astrophysics, told SPACE.com. ”It’s darker than the blackest lump of coal, than dark acrylic paint you might paint with. It’s bizarre how this huge planet became so absorbent of all the light that hits it.”
