Distant Planet May Be On Its 2nd Atmosphere, NASA’s Hubble Finds

Scientists using NASA’s Hubble Space Telescope have found evidence that a planet orbiting a distant star that may have lost its atmosphere but gained a second one through volcanic activity.

The planet, GJ 1132 b, is hypothesized to have begun as a gaseous world with a thick hydrogen blanket of atmosphere. Starting out at several times the diameter of Earth, this so-called “sub-Neptune” is believed to have quickly lost its primordial hydrogen and helium atmosphere due to the intense radiation of the hot, young star it orbits. In a short period of time, such a planet would be stripped down to a bare core about the size of Earth. That’s when things got interesting.

James Webb telescope will be finished somewhere in between next year and next century, we dont know yet.

This is great news! We know how to make another one incase we lose ours again!

I also want to be a part of NASA family🤩

I've been wondering if we could heat up Mars' core to help it regain a magnetic field and atmosphere.
