The first interstellar interloper detected passing through the Solar System, 1l/‘Oumuamua, came within 24 million miles of the Sun in 2017. It’s difficult to know exactly what ‘Oumuamua looked like, but it was probably oddly shaped and elongated, as depicted in this illustration.

The constellation Orion, the Hunter as seen in the northern winter Milky Way in February 2020. The Orion Nebula is the bright, overexposed pink glow below the Belt of Orion, while the curving arc of red is Barnard’s Loop, now thought to be a supernova remnant. The bright red glow at upper left is the Rosette Nebula. Red Betelgeuse was at its minimum the night this image was taken, at about the same brightness as Bellatrix to the right—Betelgeuse is usually about as bright as blue-white Rigel at the lower right.

Face-on spiral galaxy, NGC 628, is split diagonally in this image: The James Webb Space Telescope’s observations appear at top left, and the Hubble Space Telescope’s on bottom right. JWST’s observations combine near- and mid-infrared light and Hubble’s showcase visible light. Dust absorbs ultraviolet and visible light, and then re-emits it in the infrared. In JWST’s images, we see dust glowing in infrared light. In Hubble’s images, dark regions are where starlight is absorbed by dust.

A top-down view of the OSIRIS-REx Touch-and-Go-Sample-Acquisition-Mechanism (TAGSAM) head with the lid removed, revealing the remainder of the asteroid sample inside. The picture was taken using manual high-resolution precision photography and a semi-automated focus stacking procedure. The result is an image that can be zoomed in on to show extreme detail of the sample. The remaining sample material includes dust and rocks up to about 0.4 inch in size.

Dense thickets of the reef-building coral Desmophyllum pertusum make up most of the deep-sea coral reef habitat found on the Blake Plateau in the Atlantic Ocean. The white coloring is healthy–deep-sea corals don’t rely on symbiotic algae, so they can’t bleach. Images of these corals were taken during a 2019 expedition dive off the coast of Florida.
