The James Webb Space Telescope has discovered its first new Earth-sized exoplanet called LHS 475 b. Located just 41 light-years away and orbiting very close to a small, dim star, completing a full orbit in just two days.
And for the first time, researchers are able to study the rocky planet’s atmosphere and believe exoplanets discovered are typically large gas giants similar to Jupiter. It is harder for most telescopes to detect Earth-like planets because they are much smaller, at less than a tenth of the diameter, a news report from Nasa says.

Researchers are excited that the James Web Telescope will be able to identify more Earth-like planets in the future, after it found this one. And even more than that, it should be able to detect their atmospheres — something other telescopes cannot do with planets of this size, the report says.
