Washington: Astronomers have searched for rocky planets outside our solar system with an atmosphere – a feature considered necessary for any chance of life. Well, it looks like they finally posted one. But this hellish planet in molten rock has no hope of survival.
Its inhabitants are “super-Earths” — worlds larger than our own but smaller than Neptune — that orbit a slightly lower-mass star than the Sun and complete a rapid orbit every 18 minutes, researchers said Wednesday. hour or more
Using two instruments on the James Webb Space Telescope, infrared observations show the existence of an inhospitable atmosphere that is constantly being filled with gas from a large magma ocean.
“The atmosphere can be rich in carbon dioxide or carbon dioxide, but it can also contain other gases such as water vapor and sulfur dioxide. Current observations cannot determine the exact composition of the atmosphere,” said Renyu, a planetary scientist at NASA’s Jet Propulsion. Laboratory and Caltech Hu.
Webb’s data also do not show the thickness of the atmosphere clearly. Hu said the toxic atmosphere could be as thick as Earth, which is the densest in our solar system, or thicker than Venus.
55 The planet, called Cancri e or Janssen, is about 8.8 times the size of Earth and about twice the diameter of our planet. Mercury, the innermost planet of our solar system, orbits at a distance of 25-25 from the Sun. As a result, the surface temperature is about 3,140 degrees Celsius (1,725 a
“It’s actually one of the most famous rocky exoplanets,” said Brice-Olivier Demory, an astrophysicist and lead author of the study at the Center for Space and Habitats of the University of Bern in Switzerland, using the term exoplanet. “There are better places to vacation in our galaxy.”
This planet is probably locked in order, that is, its stars always face the opposite direction as the Moon faces the Earth. Its inhabitants are in the constellation of Cancer, about 41 light years from Earth in our Milky Way Galaxy. A light year is the distance traveled in one year, 5.9 trillion miles (9.5 trillion km). Four other planets, all gas giants, orbit their stars.
That star is gravitationally bound to other stars in a binary system. The other is a red spider, the smallest form of a normal star. The distance between these friends is 1,000 times the distance between the Earth and the Sun, and light takes six days to travel from one to the other.
