One can say that this planet is being rainy in the evening. It is raining iron, ” explains David Ehrenreich, professor at the University of Geneva in Switzerland, in a press release.
The glødande giant called WASP-76b, and is quite far away from us. The section determined in stjernebiletet Fishes. 390 light years away.
Here can it rain harder than most other places, and the planet susar around in a forrykande pace. One year on this planet answers to the two jorddagar.
the Planet was first discovered in 2013, but it is only now scientists have found out more about them gloheite of the conditions on the gasskjempa.
On dagsida of eksoplaneten it can be over 2400 degrees. It is warm enough to allow the metal to evaporate.
Scientists think the wind will take with them jerndampen over to the cool nattsida. Here it is “only” 1500 degrees.
With that being jerndampen metamorphosed into jerndropar that fall to the ground, according to the study.
IMPRESSED: Sven Wedemeyer says the discoveries that are made are the result of major technological progress in the country.

Astrophysician Sven Wedemeyer at the University of Oslo are pleased over the new discoveries.
This is very exciting. In many ways it now open a new chapter in research on eksoplanetar, ” he says.
the Climate on distant planets
the WASP-76b was examined by four large telescope in Chile, with the imaginative name by the Very Large Telescope. These are operated by the European Southern Observatory, ESO.
Instrument the ESPRESSO was originally designed to look after jordliknande planets. But now, scientists have managed to study the atmosphere of other types eksoplanetar using the same instrument.
Wedemeyer has himself visited the observatory and the four major teleskopa in Chile in the summer.
Espresso-the instrument uses light from all four teleskopa. This is verdsleiande technology, and it is impressive what they have achieved, ” he says.
the TELESCOPE IN the DESERT: It is here by ESOs Very Large Telescope they have made the discovery. The center is located in the atacama desert, northern Chile.

the WASP-76b is a eksoplanet. It means a planet that orbits around a star, in another solar system than our own. What is special about this eksoplaneten is that it always faces the same side towards the light and the heat from the star it rotates around. This is the same relationship that the moon has to the earth.
Dagsida on this planet will get many thousands of times as much radiation from the star, say, than the earth do from the sun.
This varmeklumpen lies so unbelievably close vertsstjerna say. The distance between the planet and the star is only three percent of the distance sun–earth.
According to the study are the planet therefore then inderleg bottles that molekyla parts up in the atom. Metal as iron, evaporate into the atmosphere and come down again as a rain of jerndropar on the dark and kjøligare nattsida.
Fordampinga and kondenseringa to rain means that there are large chemical variations on the day – and nattsida. This is the first time researchers have recorded something on a ultravarm gasskjempe.
Now we have a completely new way to track the climate of the most extreme eksoplanetane, ” says Ehrenreich.
He has led the study published in the journal Nature.
Looking for life
According to ESO has astronomane found around 4000 eksoplanetar outside our solar system.
Wedemeyer says it is no longer “just” is a matter of discovering new planets. Now we can actually start to get knowledge about the climate on the planets in the solar system far away from earth.
After a quarter, we can then examine the atmosfærane and the chemical samansetningar on planets that are more similar to earth. On the jordliknande planetane can such observations may show whether there are conditions for life.
Astrofysikaren Wedemeyer says this is about the big question in romforskinga: Are we alone?
