JWST Ruled Out Finding Tiny Moons Around An Exoplanet - That's Great News
The James Webb Space Telescope (JWST) has opened up many wonders of the cosmos to scientists since it began its science operations a few years ago. But one thing that it hasn’t done is find an “exomoon”. These, as yet still theoretical, moons orbit exoplanets in other star systems, and JWST was supposed to find a plethora of them. However, so far it has found precisely none. It seems the cause is noise in the telescope’s instrumentation or noise from the star itself. But a new paper, available in pre-print form on arXiv from David Kipping, an astronomer at Columbia and also the host of the Cool Worlds YouTube Channel, shows how JWST can, in fact, find an exomoon. It likely just has to look for one in the same place repeatedly.
