Scientists can already find planets in other star systems relatively easily. Now they want to be able to analyze atmospheres and signs of life with the same ease. The James Webb Space Telescope will be of great help.

this is what we know
For the first time, scientists have been able to observe a dust storm on a planet outside the solar system. Spectrometers installed on the James Webb telescope have helped.

The space observatory observed the planet VHS 1256 b. The telescope was able to distinguish water, carbon monoxide, methane, carbon dioxide, as well as dust and sand. Previously, only one parameter had been used to study the atmospheres of exoplanets.

VHS 1256 b is a planet that is only 150 million years old. By comparison, Earth is over 4.5 billion years old. The temperature in the upper atmosphere of the observed exoplanet can reach 830 degrees Celsius (1,500 degrees Fahrenheit).

VHS 1256 b is only 40 light-years from Earth and orbits two stars at the same time. It is four times further from them than Pluto is from the Sun, so its light does not mix with that of the stars.

The short distance between Earth and VHS 1256b allowed the space observatory to see the planet in relative detail. James Webb saw rising clouds of silicate sand and dust mixing with the air masses. This process lasted one day, the duration of which on the planet VHS 1256 b is 22 hours. But a year there corresponds to 10,000 Earth years.

The National Aeronautics and Space Administration (NASA) has announced a drastic change in the brightness of the planet. VHS 1256b is the first planetary-mass space object whose brightness varies extremely during the day.
