This Hubble Space Telescope image of the asteroid Dimorphos was taken on December 19, 2022, about four months after the asteroid was impacted by NASA's DART mission (Double Asteroid Redirection Test). Hubble’s sensitivity reveals a few dozen boulders knocked off the asteroid by the force of the collision. These are among the faintest objects Hubble has ever photographed inside the solar system.

This image taken with the Atacama Large Millimeter/submillimeter Array (ALMA) shows the young planetary system PDS 70, located nearly 400 light-years away from Earth. The system features a star at its center, around which the planet PDS 70 b is orbiting. On the same orbit as PDS 70b, astronomers have detected a cloud of debris that could be the building blocks of a new planet or the remnants of one already formed. The ring-like structure that dominates the image is a circumstellar disc of material, out of which planets are forming. There is in fact another planet in this system: PDS 70c, seen to the right of the inner rim of the disc.

In this artist’s rendering from 2020, the small white orb represents the white dwarf (a remnant of a long-dead sun-like star), while the purple foreground object is the newly discovered brown dwarf companion, confirmed by NASA’s Spitzer Space Telescope. This faint brown dwarf was previously overlooked until being spotted by citizen scientists working with Backyard Worlds: Planet 9, a NASA-funded citizen science project.
