This is an artist’s impression of the exoplanet 2M1510 (AB) b’s unusual orbit around its host stars, a pair of brown dwarfs. The newly discovered planet has a polar orbit, which is perpendicular to the plane in which the two stars are travelling. Polar planets around single stars had been found before, as well as polar discs of gas and dust capable of forming planets around binary stars. But thanks to ESO’s Very Large Telescope (VLT) this is the first time we have strong evidence that such a planet actually exists in a polar orbit around two stars. The two brown dwarfs appear as a single source in the sky, but astronomers know there are two of them because they periodically eclipse each other. Using the UVES spectrograph on the VLT they measured their orbital speed, and noticed that their orbits change over time. After carefully ruling out other explanations, they concluded that the gravitational tug of a planet in a polar orbit was the only way to explain the motion of the brown dwarfs.

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 ring of light surrounding the centre of the galaxy NGC 6505, captured by ESA’s Euclid telescope, is a stunning example of an Einstein ring. NGC 6505 is acting as a gravitational lens, bending light from a galaxy far behind it. The almost perfect alignment of NGC 6505 and the background galaxy has bent and magnified the light from the background galaxy into a spectacular ring. This rare phenomenon was first theorised to exist by Einstein in his general theory of relativity. This wide field shows the extended stellar halo of NGC 6505 and showcases the Einstein ring, surrounded by colourful foreground stars and background galaxies.

A close-in image of a protoplanetary disc around a newly formed star. Many different wavelengths of light are combined and represented by separate and various colours. A dark line across the centre is the disc, made of opaque dust: the star is hidden in here and creates a strong glow in the centre. A band going straight up is a jet, while other outflows form flares above and below the disc, and a tail coming off to one side.

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.

This collage highlights a small selection of regions of the Milky Way imaged as part of the most detailed infrared map ever of our galaxy. Here we see, from left to right and top to bottom: NGC 3576, NGC 6357, Messier 17, NGC 6188, Messier 22 and NGC 3603. All of them are clouds of gas and dust where stars are forming, except Messier 22, which is a very dense group of old stars.

Ancient star, but not one of the first: One of the oldest known stars ever observed is a subgiant star in the Milky Way, just 190 light-years from Earth. The star, known as HD 140283 or the Methuselah star, appears to be almost as old as the universe. However, we know it is not one of the first stars because of it contains metals that must have formed in the core or during the explosion of even earlier stars.

The central region of a spiral galaxy. Its core is a small bright point radiating bright, bluish-white light over the scene. The white light is diffuse and many point-like stars in the galaxy (and even background galaxies) can be seen through it. The galaxy’s arms can be seen as broad, swirling streaks of glowing gas and dust, coloured red and orange. Two additional arms are revealed in green

A combination of a Hubble Space Telescope image of SN 1987A and the compact argon source. The faint blue source in the center is the emission from the compact source detected with the James Webb Space Telescope. Outside this is the stellar debris, which contains most of the mass. The inner bright “string of pearls” is the gas from the outer layers of the star that was expelled about 20,000 years before the final explosion. The fast debris is now colliding with the ring, explaining the bright spots. Outside of the inner ring are two outer rings, presumably produced by the same process as forming the inner ring. The bright stars to the left and right of the inner ring are unrelated to the supernova.

Galaxy AM 1054-325 has been distorted into an S-shape from a normal pancake-like spiral shape by the gravitational pull of a neighboring galaxy, seen in this NASA Hubble Space Telescope image. A consequence of this is that newborn clusters of stars form along a stretched-out tidal tail for thousands of light-years, resembling a string of pearls. They form when knots of gas gravitationally collapse to create about one million newborn stars per cluster.

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.

This image from the Near-Infrared Camera instrument on the James Webb Space Telescope shows the central portion of the star cluster IC 348. The wispy curtains filling the image are interstellar material reflecting the light from the cluster’s stars. The bright star closest to the center of the frame is actually a pair of type B stars in a binary system, which are the most massive stars in the cluster. Winds from these stars may help sculpt the large loop seen on the right side of the field of view.

The full view of the James Webb Space Telescope’s NIRCam (Near-Infrared Camera) instrument reveals a 50 light-years-wide portion of the Milky Way’s dense center. An estimated 500,000 stars shine in this image of the Sagittarius C region, along with some as-yet unidentified features. A vast region of ionized hydrogen, shown in cyan, wraps around an infrared-dark cloud, which is so dense that it blocks the light from distant stars behind it. Intriguing needle-like structures in the ionized hydrogen emission lack any uniform orientation. Researchers note the surprising extent of the ionized region, covering about 25 light-years.

Space Telescope with visible-light data from NASA’s Hubble Space Telescope. The resulting wavelength coverage, from 0.4 to 5 microns, reveals a vivid landscape of galaxies whose colors give clues to galaxy distances: The bluest galaxies are relatively nearby and often show intense star formation, as best detected by Hubble, while the redder galaxies tend to be more distant, or else contain copious amount of dust, as detected by JWST.

This square astronomical image is divided horizontally by a waving line between a white-orange cloudscape forming a nebula along the bottom portion and a comparatively blue-purple-pink upper portion. From the nebula in the bottom half of the image, an orange cloud shaped like a horsehead sticks out. In the bottom left of the image, a white round glow is visible. The clouds from the bottom half of the image shine purple/blue light into the upper half. The top of the image shows the black expanse of space. Speckled across both portions is a starfield, showing stars of varying sizes and colors. Blue stars are younger and red stars are older.

Astronomers found the most distant black hole ever detected in X-rays (in a galaxy dubbed UHZ1) using the Chandra X-Ray Observatory and the James Webb Space Telescope. X-ray emission is a telltale signature of a growing supermassive black hole. This result may explain how some of the first supermassive black holes in the universe formed. These images show the galaxy cluster Abell 2744 that UHZ1 is located behind, in X-rays from Chandra and infrared data from JWST, as well as close-ups of the black hole host galaxy UHZ1.

An image of Jupiter taken with the James Webb Space Telescope’s NIR Cam in July 2022. Researchers recently discovered a narrow jet stream traveling 320 miles per hour sitting over Jupiter’s equator above the main cloud decks. The numerous bright white "spots" and "streaks" are likely very high-altitude cloud tops of condensed convective storms. Auroras, appearing in red in this image, extend to higher altitudes above both the northern and southern poles of the planet.

There is white and pale blue light that emanates from stars and dust at the core’s center, but it is tightly limited to the core. The rings feature colors of deep red and orange and highlight filaments of dust around cavernous black bubbles.
