Natural resources are running out. Humanity began to worry about the future of the upcoming season. Then, the special agency discovered a planet that looked like Earth. However, the site has a natural limit that can be fatal to residents.

This looks like the plot of the movie “Interstellar”, but it was released by NASA (NASA). What was discovered in 2004 was not a surging sea or a cold and desolate planet, but only 2.4 million kilometers away from a star that also resembles our sun. The problem is that it usually rains lava at night.

NASA scientists are preparing to use the powerful James Webb Telescope to explore the site. The exoplanet named 55 Cancri (planets outside our solar system are classified) was discovered in 2004. As technology improves, it will be possible to take a closer look at the place.

In late May, NASA announced that it would use James Webb to study LHS 3844 b. The two exoplanets are dubbed “super-Earths” by scientists because they are rocky and similar in size to our planet. The problem is that both have extreme climatic and geological conditions.

Because of its close proximity to the star, 55 Cancri’s heat would be very high. Since any mineral on the surface would exceed its melting point, scientists thought it was covered in an ocean of lava.

“55 Cancri e likely has a thick atmosphere dominated by oxygen or nitrogen,” said Renyu Hu of NASA’s Jet Propulsion Laboratory, whose team will use James Webb’s Infrared Camera (NIRCam) to study the daytime thermal emission spectrum planet.

He added: “If it has an atmosphere, Webb has the sensitivity and wavelength range to detect it and determine what it’s made of.”

LHS 3844 b is cooler and the rock surface must be in a solid state. The problem is that there may be no air there. The planet, 49 light-years from Earth, appears to have no atmosphere.

Studying these sites could help us understand our own planet, scientists say. “They will give us wonderful new insights into terrestrial planets, helping us understand what the early Earth looked like when it was hot, like these today,” Laura Kreidberg, of the Max Planck Institute for Astronomy, told the agency. Like planets.” . American Space.
