$This image of Messier 77 from Webb’s Mid-Infrared Instrument (MIRI) highlights its swirling spiral arms, the dust in its disk and its piercingly bright core like never before. The bright orange lines appearing to radiate out from the galaxy’s center are not actually a feature of the galaxy: they are a type of distortion that arises from the optical design of the telescope. Called diffraction spikes, they are created because the intense light from the unresolved AGN is bent (diffracted) very slightly at the edges of Webb’s hexagonal mirror panels and around one of the struts that hold up its secondary mirror.

This artist’s impression shows an imagined view from the surface one of the three exoplanets orbiting the ultracool dwarf star TRAPPIST-1 38.8 light-years from Earth. These alien worlds have sizes and temperatures similar to those of Venus and Earth. In this view one of the inner planets is seen in transit across the disc of TRAPPIST-1. Image credit: M.

Webb captured the auroral footprints of Io and Europa, providing spectral measurements for the first time, and revealing extreme changes in the physical properties within Io’s auroral footprint that are likely linked to the electrons crashing into the top of Jupiter’s atmosphere.
