Blacker than new asphalt: darkest planet found in the milky way


A team of astronomers from Canada and the UK said the constellation Auriga the darkest planet known to date. As experts explain, this celestial body is practically reflects the rays of its star, which it is heated to extremely high temperatures.

The planet, called WASP-12b, in size about two times that of Jupiter, scientists suggest. However, she represents only 0.64 percent of the total light falling on it. As a result, the surface temperature of the space object 2 reaches 600 degrees Celsius — it is almost enough to draw the iron to steam.

According to scientists, in order to “soak up” the light so effectively, the entire or almost the entire surface of the planet should have a more deep black color than newly laid asphalt. Researchers still find it difficult to say exactly how this must be the composition of the surface and atmosphere of the planet, however, whatever it was, the discovery may broaden our understanding of the diversity of celestial bodies outside the Solar system.

WASP-12b was discovered in 2008, but its unique properties experts have discovered only now scientists have discovered that the luminosity of the star WASP-12 practically does not depend on is the planet in front of her or the opposite side relative to the Earth. In order to learn it, experts have used data previously obtained with a telescope “Hubble”.

The study was published in the journal Astrophysical Journal Letters.

Space telescope “Hubble”, functioning in the framework of the joint project of the American space Agency NASA and the European space Agency, was launched into orbit on 24 April 1990.
