The center of the image has the brightest pixel, indicating where the comet is. The next brightest shades in the image indicate areas where the instrument detected atoms of hydrogen coming from the comet. This hydrogen is released when sunlight heats the comet, causing its water ice to turn directly into vapor. Once released into space, the water molecules break apart into oxygen and hydrogen atoms.

A large planetary nebula. The nebula’s central star is hidden by a blotchy pinkish cloud of dust. A strong red light radiates from this area, illuminating the nearby dust. Two large loops extend diagonally away from the centre, formed of thin ridges of molecular gas, here coloured blue. They stretch out to the corners of the view. A huge number of bright, whitish stars cover the background, also easily visible through the thin dust layers.

By Andrew Paul

This artist’s concept visualizes a kilonova – an explosion that happens when two neutron stars or a neutron star and a black hole collide and merge. When these collisions happen, a fraction of the resulting debris is ejected as jets, which move near the speed of light. The remaining debris produces hot, glowing, neutron-rich clouds that forge heavy elements, like gold and platinum. Researchers will mine data from NASA’s Nancy Grace Roman Space Telescope, which will survey the same areas of the sky every few days, to identify kilonovae. Roman’s extensive data will help astronomers better identify how often these events occur, how much energy they give off, and how near or far they are.

These images, showing ejecta around the impacted near-Earth asteroids, were taken during the approach (with Didymos to the upper left) and departure (Didymos to the upper right) of DART's companion spacecraft, LICIACube, which flew past a few minutes after the impact and imaged the aftermath. The ejecta field consists of an asymmetric cone of dust that exhibits streamers and filaments, as well as over a hundred meter-sized boulders that were ejected in preferred directions.

A photomosaic taken by the Curiosity Rover on April 30, 2023 at the Ubajara drill site in Gale Crater, Mars. Rock powder samples drilled here contained substantial amounts of siderite (an iron carbonate mineral). The siderite played a role in ancient carbon cycling processes that impacted conditions at the planet’s surface. Rover tracks in the foreground are 40 cm wide. (Credit: NASA/JPL-Caltech/MSSS)

A collage of three images showing the black expanse of space. Two-thirds of the collage is taken up by the black background sprinkled with small, blurry galaxies in orange, blue, and white. There are two images in a column at the right side of the collage. On the right side of the main image, not far from the top, a very faint dot is outlined with a white square. At the right, there are two zoomed in views of this area. The top box is labeled NIRCam and shows a fuzzy dot at the center of the inset. The bottom box is labeled MIRI and shows a fuzzy pinkish dot.

A colorful, glowing nebula that reaches beyond the top and bottom of the image. It is made of translucent clouds of gas: wispy and thin with hard edges in some places, and puffy and opaque in others. Blue, red and yellow colours mix together, showing light emitted by different types of atoms in the hot gas. Bright and pointlike stars are scattered across the nebula. The background is black

The first image depicts star cluster NGC 602 in vibrant and festive colors. The cluster includes a giant dust cloud ring, shown in greens, yellows, blues, and oranges. The green hues and feathery edges of the ring cloud create the appearance of a wreath made of evergreen boughs. Hints of red representing X-rays provide shading, highlighting layers within the wreath-like ring cloud. The image is aglow with specks and dots of colorful, festive light, in blues, golds, whites, oranges, and reds. These lights represent stars within the cluster. Some of the lights gleam with diffraction spikes, while others emit a warm, diffuse glow. Upon closer inspection, many of the glowing specks have spiraling arms, indicating that they are, in fact, distant galaxies.
