The James Webb telescope, which was sent into space about a year ago, has made many new discoveries and can now add a new one to its successes.

The world’s largest telescope has discovered a planet and it looks very similar to Earth.

Scientists plan to make new observations in the future to find out more about this new planet.

What did scientists find?

The rocky planet has been named LHS 475 b and is located 41 light-years away in the constellation Octans.

Although the planet was first noticed by NASA satellites, it was the James Webb telescope that first saw the planet and confirmed its existence.

Since the planet was just discovered, there is much unknown about LHS 575 b, but experts have confirmed the first details about the planet.

The planet is small, rocky and almost the same size as Earth. It’s also several hundred degrees hotter than our planet.

Experts are still trying to find out if the planet has an atmosphere, but they are sure that it does not have a thick methane atmosphere like Saturn’s moon Titan.

Scientists are excited about this new discovery and expect the large telescope to find many new planets in the future.

“The first observations from this new Earth-sized rocky planet could open the door to Webb and the study of the atmospheres of many rocky planets,” said NASA Director Mark Clampin.

“Webb brings us closer to Earth-like planets outside our solar system, and its mission has just begun.”

Experts hope to learn more about the new planet, and new observations are expected this summer.
