Natural resources are running out. Humanity begins to worry about the future of the coming seasons. Then the special agency finds a planet that looks like Earth. However, the site has natural limitations that can be dangerous for residents.

It looks like the story of an interstellar movie, but it is news released by NASA (US Space Agency). The discovery made in 2004 is only 2.4 million kilometers away from the star, which is very similar to our sun, than a giant ocean with huge waves or a cold and uninhabited planet. The problem is that lava rains usually fall at night.

US space agency scientists are preparing to use the powerful James Webb Telescope to explore the site. Named Cancri 55, an exoplanet (as classified as a planet outside the solar system) was discovered in 2004. Technological advances will make it possible to observe the site more closely.

In late May, NASA announced that it would use James Webb to study LHS 3844 b. Scientists have called the two exoplanets “super-Earth” because they are rocky and close in size to our planet. The problem is that both have extreme climatic and geographical conditions.

Because it is so close to the star, the heat of 55 Cancri will be higher. Since any mineral on the surface exceeds its melting point, scientists believe that it is covered by lava oceans.

“The 55 Cancri e may have a dense atmosphere dominated by oxygen or nitrogen,” says Renu Hu of NASA’s Jet Propulsion Laboratory, who will study the daytime thermal emission spectrum using James Webb’s infrared camera (NIRCam). Of the planet

He adds that “if there is an atmosphere in it, the web has a sensitivity and wavelength range to find out and determine what it is made of.”

LHS 3844 b is cold and the rocky surface must be in solid state. The grip is such that maybe there is no air. At 49 light-years from Earth, the planet has no visible atmosphere.

Scientists say that studying these places can help us understand our own planet. Laura Kredberg of the Max Planck Institute for Astronomy told the agency: “They will give us fantastic new perspectives on Earth-like planets in general, which will help us understand what the early Earth looked like when it was as hot as today’s planets.” American space.
