The NASA/ESA Hubble Space Telescope imaged these two overlapping spiral galaxies named SDSS J115331 and LEDA 2073461, which lie more than a billion light-years from Earth. Despite appearing to collide in this image, the alignment of the two galaxies is likely just by chance – the two are not actually interacting. While these two galaxies might simply be ships that pass in the night, Hubble has captured a dazzling array of other, truly interacting galaxies.

Astronomers have been bemused to find young stars spiralling into the centre of a massive cluster of stars in the Small Magellanic Cloud, a satellite galaxy of the Milky Way. The outer arm of the spiral in this huge, oddly shaped stellar nursery — called NGC 346 — may be feeding star formation in a river-like motion of gas and stars. This is an efficient way to fuel star birth, researchers say.

NASA’s Juno spacecraft observed the complex colors and structure of Jupiter’s clouds as it completed its 43rd close flyby of the giant planet on July 5, 2022. Citizen scientist Björn Jónsson created these two images using raw data from the JunoCam instrument aboard the spacecraft. At the time the raw image was taken, Juno was about 3,300 miles (5,300 kilometers) above Jupiter’s cloud tops, at a latitude of about 50 degrees. North is up. At that moment, the spacecraft was traveling at about 130,000 mph (209,000 kilometers per hour) relative to the planet.
