An artist's impression shows the internal structure of Jupiter's moon Io. Data from NASA's Juno spacecraft indicate that Io does not have a shallow global magma ocean, and is consistent with a mostly solid mantle (shown in green), with significant molten material (yellow and orange), above a liquid core (red/black).

Quasar J0742+2704 (center) became a topic of interest for astronomers in 2020 after it was discovered to have a new jet emanating from the disk around its supermassive black hole. The discovery was made using the Karl G. Jansky Very Large Array (VLA) radio observatory. Follow-up observations were subsequently made with other observatories, with the aim of determining the properties of the galaxy and understanding what might have powered the jet. **Credit:** NASA, ESA, Kristina Nyland (US Naval Research Laboratory); Image processing: Joseph DePascala (STScI).

This image of the Sombrero galaxy, taken by Webb's Medium AA camera, is shown with compass arrows, a scale, and a color key. The image shows wavelengths of medium AA light translated into visible light colors. The color key shows the filters used when they collected the light. The color of each filter name is the color of the visible light used to represent the AA light passing through that filter. The north and east compass arrows show the direction of the image in the sky. Credit: NASA, ESA, CSA, STScI
