Radio signal from the quasar TXS 2005+403 travels roughly 10 billion light-years to reach Earth, traversing the Cygnus region, one of the most turbulent and scattering environments in the Milky Way Galaxy. On the left, this artist’s conception shows the quasar as it truly appears, with a bright accretion disk and jets blasting into the Galaxy like a beacon through the darkness. On the right, we see how turbulent gas distorts scientists’ view of the quasar in much the same way heat haze from a fire warps our view of the objects behind it. Image credit: Melissa Weiss / CfA.

$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.
