The James Webb telescope showed the first dust storm outside the solar system
Clouds filled with silicate dust have been detected in the atmosphere of exoplanet VHS 1256 b. The planet is located about 40 light years from Earth. The temperature of these clouds reaches 830 degrees Celsius.
The James Webb Space Telescope first showed a dust storm outside the solar system, it was found in the atmosphere of the exoplanet VHS 1256 b. Image published on the website of the US National Aeronautics and Space Administration (NASA).
The planet VHS 1256 b lies about 40 light-years from Earth and orbits not one, but two stars. This planet makes a complete revolution in its orbit in about 10 thousand years. Moreover, VHS 1256 b is about four times farther from its stars than Pluto is from the Sun, the researchers note. The age of the planet is about 150 million years (the age of the Earth is 4.5 billion years. - RBC ).
In the image taken from data from the telescope, you can see swirling clouds filled with silicate dust. They rise, mix, and move throughout the 22-hour day. The researchers found both brighter and darker sections of the clouds, indicating that some clouds are lower and hotter or higher and colder than others, respectively. In the atmosphere where these silicate clouds form, the temperature reaches 1.5 thousand degrees Fahrenheit (830 degrees Celsius).
Last September, the James Webb telescope took a picture of another planet outside the solar system. We are talking about the planet HIP 65426 b, a gas giant discovered in 2017.
According to various estimates, the planet is 6-12 times larger than Jupiter, and it is from 15 million to 20 million years old. HIP 65426 b is about 100 times farther from its parent star than the Earth is from the Sun. The distance to this planet from Earth is 385 light years.
The James Webb telescope was launched in December 2021. The device was named after the second director of NASA, who led the agency from 1961 to 1968. In July 2022, the telescope captured the deepest, sharpest, and most detailed image of the distant universe. The image captured the galaxy cluster SMACS 0723, which "covers a patch of sky about the size of a grain of sand that someone on Earth holds at arm's length," NASA explained.
