It has rocky terrain .. "NASA" discovers "the planet similar to Earth"

 NASA's "James Webb" space telescope discovered its first planet, which turned out to have rocky terrain and resemble our planet Earth. The planet is classified outside the solar system, and it constitutes 99 percent of the diameter of the Earth. Although it has Earth-like terrain, scientists do not yet know if it has an atmosphere.

Although the team cannot at the present time reach a definitive answer, they ruled out the existence of a dense atmosphere dominated by methane gas, as is the case in the atmosphere of Saturn's moon "Titan". And the James Webb telescope revealed that the planet, which is located 41 light years away, is "a few hundred degrees warmer than Earth, and it completes its orbit in two days."

There is still much for scientists to discover regarding the planet called "LHS 475 b", especially since such planets are "invisible" to space telescopes, but James Webb has proven once again how powerful his technique is.

"These first observational results from an Earth-sized rocky planet open the door to many future possibilities for studying the atmospheres of rocky planets using Webb," Mark Clampin, director of the Astrophysics Division at NASA Headquarters in Washington, said in a statement.

He continued, "James Webb is bringing us closer and closer to a new understanding of Earth-like worlds outside our solar system, and the mission is still in its infancy." While this discovery is startling, scientists are now working to determine the composition of the planet's atmosphere.

The team notes that although "the planet may not have an atmosphere, some atmospheric compositions, such as a carbon dioxide atmosphere, have not been ruled out," according to the British Daily Mail.

"Unexpectedly, the atmosphere, which is 100 percent carbon dioxide, is so much more compact that it becomes very difficult to detect," Jacob Lustig-Yeger of the Johns Hopkins University Applied Physics Laboratory said in a statement.

More precise measurements are now required for the team to distinguish a pure carbon dioxide atmosphere from no atmosphere at all. Lustig-Yeger explained that his team is "at the forefront of studying small, rocky exoplanets," noting their interest in studying the atmospheres of these planets.

The results of the research opened up the possibility of identifying Earth-sized planets orbiting smaller red dwarf stars. Last November, NASA announced that the telescope "successfully revealed the composition of the atmosphere of an exoplanet, in details never seen before," in an achievement indicating that it can also search for "space life."
