The first direct surveillance of the planet "super buyer" outside our solar system

Astronomers made the first direct observations of a planet outside the solar system, using a technique combining light from several telescopes.

The "super buyer" has discovered 129 light-years from Earth, with a stormy atmosphere and clouds of iron and silicate.

Scientists often have to use indirect methods to study the outer planets because of the mysterious light of their stars.

In this study, scientists used a technique called "optical interference" that allowed four telescopes to function as a single instrument, leading to an imaging system sensitive enough to disassemble the light of the planet and the planet. ;star.

The planet, known as the HR8799e, discovered by scientists in 2010, gravitates around a star in the constellation Pegasus.

"Our observations indicate that there is a gas ball lit from the inside, with rays of warm light floating through storm clouds of dark clouds," said Sylvester Lacour, of the Paris Observatory in France and the Max Planck Institute of Physics.

The results of Gravity, a tool combining 4 light beams from the interference scale of the very large telescope of the European Southern Observatory (VLTI) in Chile, were published in Astronomy and Astrophysics.
