Search for Earth-like planet outside the solar system, claims NASA

NASA claims to have discovered an Earth-sized planet outside the solar system using the James Webb Space Telescope. Researchers say that the exoplanet named LHS FourSevenFiveB (LHS475B) is several hundred degrees hotter than Earth.

NASA claims to have discovered this rocky planet in the constellation Octane using the world's largest and most powerful James Webb Space Telescope. The announcement of the planet's discovery was made Wednesday at the 241st meeting of the American Astronomical Society in Seattle.

James Webb is the only telescope capable of probing the atmospheres of Earth-sized exoplanets. To find out if the newly discovered planet has an atmosphere, the researchers experimented with multiple wavelengths of light. But they did not come to any definite conclusion about whether the planet has an atmosphere at all.

The planet is located 41 light years away from Earth. Scientists say that its diameter is 99% equal to the diameter of the earth. However, its temperature is several hundreds of degrees higher than Earth's.

The hypothesis about the planet's existence matches previous data collected by NASA's Transiting Exoplanet Survey satellite-TES.

Jacob Lustig-Yeager, a researcher at the Johns Hopkins University Applied Physics Laboratory, said that a cosmic object orbiting another cosmic object in front of it is called a transit. In this case, two transits of this new planet have been seen. We saw the first transit on August 31 and the second transit on September 4 last year.

Meanwhile, NASA said the planet is unlikely to have a strong methane-rich atmosphere like Saturn's moon Titan.

The planet completely orbits its star every 2 days. However, since the star's temperature is less than half that of the Sun, researchers expect the planet to have an atmosphere.
