Astronomers shocked. Detected unusual

Scientists first discovered in the atmosphere of exoplanets an element that had never been found before.

A team of astronomers first discovered in the upper layers of the planets WASP-76b and WASP-121b barium. It is a silvery white metal that is used to make fireworks green. But most importantly, for the first time, scientists have discovered the heaviest element found on exoplanets, writes Forbes.

The planets WASP-76b and WASP-121b are so-called “hot Jupiters” that orbit different stars. They are huge gas giants like Jupiter or Saturn. But these planets revolve around their stars at a very close distance and the year on these planets lasts only 2 Earth days.

WASP-76b is about 400 light-years away and on the side facing its star, the temperature reaches 2400 degrees Celsius. WASP-121b is about 900 light-years away, and the temperature on the side facing the star reaches 3000 degrees Celsius.

These planets are united by the fact that it rains from metals, in particular from iron. This is due to the very high temperature causing the metals to vaporize on one side of the planets. Then they move to the other side, where it is much colder and condense into droplets and fall out as rain.

But scientists are shocked that they were able to detect barium, which is 2.5 times heavier than iron, in the upper atmospheres of these planets. It is the heaviest element that has been detected in the atmosphere of exoplanets to date.

According to Olivier Demanjon from the University of Porto, Portugal, these planets have huge gravity, which means that heavy elements like barium should quickly move into the lower atmosphere, but this does not happen.

“At first, we don't even believed they found barium, because this element had never been found in the atmospheres of distant exoplanets. We double-checked everything and it really turned out that barium is there, “says Demangeon.

According to scientists, their discovery makes “hot Jupiters” even more unusual and full of mysteries planets. These gas giants are much easier to study than distant rocky planets like Mars or Earth because they are much larger. Nevertheless, scientists still know too little about these objects, since they have no analogues in the solar system.

Focus has already written in detail about the features of the planet WASP-76b and the planet WASP -121b, where it also rains gemstones.

As for objects in our solar system, Focus has already written that scientists have discovered unusual activity of lakes under the surface Jupiter's moon Europa.
