The James Webb Space Telescope has captured an image of a mini-Neptune outside our solar system. This discovery is significant as mini-Neptunes are an intermediate type of exoplanet that have characteristics of both gas and rock planets. The mini-Neptune in question has been classified as a super-puff, meaning that it has a thick atmosphere with a low density, giving it a larger size than expected for its mass.

The image was taken during the telescope's initial testing phase and is part of a larger effort to study exoplanets and their atmospheres. By analyzing the light that passes through the mini-Neptune's atmosphere, scientists can determine its composition and potentially find signs of life.

The James Webb Space Telescope is set to launch in October 2021 and will be the largest and most powerful space telescope ever built. Its advanced capabilities will allow scientists to study the universe in unprecedented detail and make groundbreaking discoveries like this one.
