James Webb Space Telescope will help assess atmospheres of strange ‘sub-Neptunes’

The sharp mirrors of the James Webb Space Telescope will finally be able to probe into the atmospheres of sub-Neptunes, which are mysterious planets that aren’t found anywhere near Earth.

The observatory is in the middle of a commissioning period that will last until about June. But when it is ready, the observatory will seek out sub-Neptunes that are close to their parent stars to assess more about the “fundamental nature” of these large planets, NASA said.
