Picture of the Month 2025

29 August 2025
For this new Picture of the Month feature, the NASA/ESA/CSA James Webb Space Telescope has provided a fantastic new view of IRAS 04302+2247, a planet-forming disc located about 525 light-years away in a dark cloud within the Taurus star-forming region. With Webb, researchers can study the properties and growth of dust grains within protoplanetary discs like this one, shedding light on the earliest stages of planet formation. In stellar nurseries across the galaxy, baby stars are forming in giant clouds of cold gas. As young stars grow, the gas surrounding them collects in narrow, dusty protoplanetary discs. This sets the scene for the formation of planets, and observations of distant protoplanetary discs can help researchers understand what took place roughly 4.5 billion years ago in our own Solar System, when the Sun, Earth, and the other planets formed. IRAS 04302+2247, or IRAS 04302 for short, is a beautiful example of …

This image from the NASA/ESA/CSA James Webb Space Telescope revisits one of the most iconic regions of the sky, the Hubble Ultra Deep Field, through the eyes of two of Webb’s instruments. The result is a detailed view that reveals thousands of distant galaxies, some dating back to the earliest periods of cosmic history.The field shown here, known as the MIRI Deep Imaging Survey (MIDIS) region, was observed with the three shortest-wavelength filters of Webb’s Mid-Infrared Instrument (MIRI) for nearly 100 hours in total. This included Webb's longest observation of an extragalactic field in one filter so far, producing one of the deepest views ever obtained of the Universe. Combined with data from Webb’s Near-Infrared Camera (NIRCam), this image allows astronomers to explore how galaxies formed and evolved over billions of years. These deep observations have revealed more than 2500 sources in this tiny patch of sky. Among them are …

Featured in this NASA/ESA/CSA James Webb Space Telescope Picture of the Month is a nearby galaxy that outshines the Milky Way. This galaxy, called Messier 82 (M82) or the Cigar Galaxy, is situated just 12 million light-years away in the constellation Ursa Major. Despite being smaller than the Milky Way, M82 is five times as luminous as our home galaxy and forms stars ten times faster. M82 is classified as a starburst galaxy because it is forming new stars at a rate much faster than expected for a galaxy of its mass, especially at its centre. In visible-light images of M82, the central hotbed of activity is obscured by a network of thick and dusty clouds. Webb’s Near-InfraRed Camera (NIRCam) has drawn back these clouds, revealing the full brilliance of the galactic centre. What caused M82’s burst of star formation? The answer likely lies with its neighbour, the larger spiral …

The eye is first drawn, in this new NASA/ESA/CSA James Webb Space Telescope Picture of the Month, to the central mega-monster that is galaxy cluster Abell S1063. This behemoth collection of galaxies, lying 4.5 billion light-years from Earth in the constellation Grus (the Crane), dominates the scene. Looking more closely, this dense collection of heavy galaxies is surrounded by glowing streaks of light, and these warped arcs are the true object of scientists’ interest: faint galaxies from the Universe’s distant past. Abell S1063 was previously observed by the NASA/ESA Hubble Space Telescope’s Frontier Fields programme. It is a strong gravitational lens: the galaxy cluster is so massive that the light of distant galaxies aligned behind it is bent around it, creating the warped arcs that we see here. Like a glass lens, it focuses the light from these faraway galaxies. The resulting images, albeit distorted, are both bright and magnified …

This new Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope features an astounding number of galaxies. The objects in this frame span an incredible range of distances, from stars within our own Milky Way, marked by diffraction spikes, to galaxies billions of light-years away. The star of this field is a group of galaxies, the largest concentration of which can be found just below the centre of this image. These galaxies glow with white-gold light. We see this galaxy group as it appeared when the Universe was 6.5 billion years old, a little less than half the Universe’s current age. The image on the left combines infrared data from both Webb and the NASA/ESA Hubble Space Telescope, showcasing the galaxy cluster against a backdrop of thousands of other galaxies. The image on the right adds X-ray data from ESA’s XMM-Newton space observatory and NASA’s Chandra X-ray Observatory …

This new NASA/ESA/CSA James Webb Space Telescope Picture of the Month features a rare cosmic phenomenon called an Einstein ring. What at first appears to be a single, strangely shaped galaxy is actually two galaxies that are separated by a large distance. The closer foreground galaxy sits at the center of the image, while the more distant background galaxy appears to be wrapped around the closer galaxy, forming a ring. Einstein rings occur when light from a very distant object is bent (or ‘lensed’) about a massive intermediate (or ‘lensing’) object. This is possible because spacetime, the fabric of the Universe itself, is bent by mass, and therefore light travelling through space and time is bent as well. This effect is much too subtle to be observed on a local level, but it sometimes becomes clearly observable when dealing with curvatures of light on enormous, astronomical scales, such as when …

The target of today’s NASA/ESA/CSA James Webb Space Telescope Picture of the Month is the spiral galaxy NGC 2283. This galaxy resides roughly 45 million light-years away in the constellation Canis Major. Classified as a barred spiral galaxy, NGC 2283’s central bar of stars is encircled by loosely wound spiral arms. This new image shows NGC 2283 through the eyes of Webb’s Near-InfraRed Camera (NIRCam) and Mid-InfraRed Instrument (MIRI). Webb gazed at NGC 2283 for a combined 17 minutes to collect the data for this image, which is constructed from six snapshots taken with different near- and mid-infrared filters. These filters reveal the emission from NGC 2283’s sparkling stellar population, as well as the light from clouds of hydrogen gas that have been heated by young stars. Sooty molecules called polycyclic aromatic hydrocarbons, of great interest to astronomers, emit light that’s mapped by two of the filters used here. The …

This new NASA/ESA/CSA James Webb Space Telescope Picture of the Month presents HH 30 in unprecedented resolution. This target is an edge-on protoplanetary disc that is surrounded by jets and a disc wind, and is located in the dark cloud LDN 1551 in the Taurus Molecular Cloud. Herbig-Haro objects are small nebulae found in star formation regions, marking the locations where gas outflowing from young stars is heated into luminescence by shockwaves. HH 30 is an example of where this outflowing gas takes the form of a narrow jet. The source star is located on one end of the jet, hidden behind an edge-on protoplanetary disc that the star is illuminating. HH 30 is of particular interest to astronomers. In fact, the HH 30 disc is considered the prototype of an edge-on disc, thanks to its early discovery with the NASA/ESA Hubble Space Telescope. Discs seen from this view are …
