WASP-43b - New terrifying planet than hell

On a planet hundreds of light years from Earth, the wind blows at the same speed as sound, and the temperature is so high that it melts and water evaporates continuously.

NASA's Hubble Space Telescope detects a very strange gas planet outside the solar system.WASP-43b , the name of the planet, about 260 light-years from Earth, so Hubble's glass cannot take pictures. However, based on its data, American astronomers are still able to map the temperature of the atmosphere surrounding the planet, while calculating the volume and distribution of water vapor in the atmosphere. .

"Temperature and water parameters help us compare the properties of different planets," said Jacob Bean, an astronomer at the University of Chicago in the US.

Analysis results show that WASP-43 is about the same size as Jupiter, but the density of matter is nearly twice as high. It revolves around a yellow dwarf. The distance between the two objects is so short that the planet only takes 19 days to rotate around the star. Its half is always facing the star, like the side of the moon is always towards the earth. So it has half an eternal glow and an eternal half-dark.

The eternal half-bright temperature of WASP-43b reaches more than 1,600 degrees Celsius - large enough to melt iron. The wind in the bright half of the planet blew with the speed of sound. On the contrary, the eternal dark half is very cold, with the temperature always at a negative level.

"WASP-43 is so hot that water in its atmosphere evaporates instantly, not condensing into ice clouds like Jupiter," said Laura Kreidberg, an expert at the University of Chicago.
