According to NASA, they are the most common type of planet in the galaxy, although none exist in our solar system. Planets such as GJ 1214b are often referred to as mini-Neptune planets because they're smaller than Neptune but with a similar atmospheric makeup. The James Webb Space Telescope recently helped to reveal new information about the planet, formally named GJ 1214b. "This is going to point us toward a lot of further studies to try to understand what those hazes could be." This artist's concept depicts the planet GJ 1214 b, a "mini-Neptune" with what is likely a steamy, hazy atmosphere.

It's bright, it's reflective and that's confusing and surprising," Kempton said, according to the University of Maryland. Neptune is the only planet in our solar system that cannot be studied without the aid of an optical tool such as binoculars or a small telescope (Neptune. "Whatever is making up the hazes or clouds is not what we expected. Eliza Kempton, an associate professor of Astronomy at the University of Maryland and lead author of the study, said she's been trying to get a clearer picture of the planet for more than a decade. The distant planet, which is outside of our solar system about 40 light-years away, is totally covered in a deep haze that has made it difficult to study since it was first discovered in late 2009, researchers said. A strange planet that's stymied astronomers for years has an "unusually shiny atmosphere" and could be home to large amounts of water vapor, scientists said in a study published Wednesday in the journal Nature.
