This distorted galaxy is the wreckage of a head-on collision between two spiral galaxies which likely occurred 500 million years ago, and it is studded with clumps of young stars which were formed as gas and dust from the two galaxies collided.
The first image contains data from the NASA/ESA Hubble Space Telescope’s Advanced Camera for Surveys and Wide Field Camera 3. Here the visible light lays out in detail the dark threads of dust and molecular gas that spin around the centres of the two merged galaxies. Many of the young, infrared-emitting stars produced by the collision are obscured in visible wavelengths by this dark dust.
The second image contains data from the NASA/ESA/CSA James Webb Space Telescope, using both the Near-InfraRed Camera and the Mid-InfraRed Instrument. The collision that produced NGC 3256 spurred an enormous burst of star formation, and these new stars radiate enormously brightly in infrared wavelengths as seen here.

This Milky Way-sized galaxy lies about 120 million light-years away in the constellation Vela, and is a denizen of the Hydra-Centaurus Supercluster.
NGC 3256 may seem peaceful, a swirl of tightly entwined spiral arms set in a hazy cloud of light, but this image shows the aftermath of an ancient cosmic clash. This distorted galaxy is the wreckage of a head-on collision between two equally massive spiral galaxies which astronomers estimate to have met around 500 million years ago. The tumultuous past of NGC 3256 is captured in the long tendrils of bright gas and stars which extend outwards from the main body of the galaxy. These luminous tendrils are called tidal tails, and are studded with young stars which were formed as gas and dust from the two galaxies collided.

The Orion Nebula has been studied by astronomers for hundreds of years, and it has been a frequent target of the Hubble Space Telescope since its launch. This comparison shows the striking difference in views afforded by a visible-light telescope, such as Hubble, and an infrared telescope like Webb.
In Webb’s image, infrared light is able to penetrate the dust, but the heated gas also emits its own infrared light, making for a colourful scene with filaments and cavities. In the Hubble image, which was taken during 2004 and 2005, bubbles of gas appear to float in front of the thick, smoky clouds of the nebula. Numerous new stars, some with protoplanetary discs, are visible across both images.

They accomplished this feat with a cross-disciplinary expert analysis, including key input from laboratory spectroscopists. The vital role of CH3+ in interstellar carbon chemistry has been predicted since the 1970s, but Webb’s unique capabilities have finally made observing it possible — in a region of space where planets capable of accommodating life could eventually form.
This video features NIRCam’s view of the Orion Bar region studied by the team of astronomers. Bathed in harsh ultraviolet light from the stars of the Trapezium Cluster, it is an area of intense activity, with star formation and active astrochemistry. This made it a perfect place to study the exact impact that ultraviolet radiation has on the molecular makeup of the discs of gas and dust that surround new stars. The radiation erodes the nebula’s gas and dust in a process known as photoevaporation; this creates the rich tapestry of cavities and filaments that fill the view. The radiation also ionises the molecules, causing them to emit light — not only does this create a beautiful vista, it also allows astronomers to study the molecules using the spectrum of their emitted light obtained with Webb’s MIRI and NIRSpec instruments.
The two very large, bright stars are two of the three stars in the θ² Orionis system — the Trapezium Cluster is also known as θ¹ Orionis. The brightest star here, θ² Orionis A, is surrounded by particularly bright and red puffs of dust, which are reflecting the star’s light towards Earth. Its great brightness — it is visible with the naked eye — is due to the fact that θ² Orionis A is itself a ternary system made of three closely bound bright stars.

Hubble has revolutionised astronomy with its detailed observations of distant stars and galaxies. The telescope has given us insights into the deep Universe, from exoplanets, black holes and the Hubble Deep Fields, to the science of cosmology and the expansion of the Universe. Hubble has also been invaluable for studying objects closer to home. We have gained a new understanding of the outer Solar System planets since its launch, not least our most massive neighbour, Jupiter.
This video highlights Hubble’s contributions to the study of Jupiter, and as the space telescope enters its 34th year of science operations, the European Space Agency has this April launched a new mission to the giant planet — the Jupiter Icy Moons Explorer, Juice.

The new image features dramatic rings as well as bright features in the planet’s atmosphere. The new Webb data of Uranus offer exquisite sensitivity, revealing the faintest dusty rings.
The seventh planet from the Sun, Uranus is strange: it rotates on its side, at a nearly 90-degree angle from the plane of its orbit. This causes unusual seasons since the planet’s poles experience 42 years of constant sunlight and 42 years of complete darkness (Uranus takes 84 years to orbit the Sun). Currently, it is late spring at the northern pole, which is on the right side of this image; Uranus’s northern summer will be in 2028.

Streaks of light and bright arcs betray the presence of a vast gravitational lens in this image. A galaxy cluster in the foreground has magnified distant galaxies, warping their shapes and creating the bright smears of light spread throughout this image. This effect, referred to by astronomers as gravitational lensing, occurs when a massive celestial object such as a galaxy cluster causes a sufficient curvature of spacetime for light to be visibly bent around it, as if by a gargantuan lens.
One of the consequential effects of gravitational lensing is that it can magnify distant astronomical objects, letting astronomers study objects that would otherwise be too faint or far away. This useful quirk of gravitational lensing has also been used to reveal some of the most distant galaxies humanity has ever encountered. The long, bright, and distorted arc spreading out near the core is one such example. A distant galaxy known as the Cosmic Seahorse, its brightness is greatly magnified by the gravitational lens, which has enabled astronomers to study star formation there.
This image was captured by NIRCam, Webb’s primary near-infrared camera, and contains the lensing galaxy cluster SDSS J1226+2149. It lies at a distance of around 6.3 billion light-years from Earth, in the constellation Coma Berenices. By combining Webb’s sensitivity with the magnifying effect of gravitational lensing, astronomers were able to use this gravitational lens to explore the earliest stages of star formation in distant galaxies. To do so, they relied on earlier studies by the NASA/ESA Hubble Space Telescope, which provided the ‘prescription’ for this gravitational lens.
This image shows only one observation from a programme designed to probe star formation in distant galaxies. As well as revealing how quickly stars form and characterising the environments in these galaxies that gave rise to new stars, these observations will demonstrate the capabilities of Webb and provide richly detailed datasets to the astronomical community. Astronomers expect Webb’s crystal-clear vision and cutting-edge instruments to provide new insights into star formation in distant, gravitationally lensed galaxies.

The outer planets beyond Mars do not have solid surfaces to affect weather as on Earth. And sunlight is much less able to drive atmospheric circulation. Nevertheless, these are ever-changing worlds. And Hubble — in its role as interplanetary meteorologist — is keeping track, as it does every year. Jupiter’s weather is driven from the inside out, as more heat percolates up from its interior than it receives from the Sun. This heat indirectly drives colour-change cycles in the clouds, like the cycle that’s currently highlighting a system of alternating cyclones and anticyclones. Uranus has seasons that pass by at a snail’s pace because it takes 84 years to complete one orbit about the Sun. But those seasons are extreme, because Uranus is tipped on its side. As summer approaches in the northern hemisphere, Hubble sees a growing polar cap of high-altitude photochemical haze that looks similar to the smog over cities on Earth.

Kilpatrick Music: Stellardrone - Billions and BillionsPan: Hubble’s neighbourhood watchHubbleWebbESA2023-03-23 | UGCA 307 hangs against an irregular backdrop of distant galaxies in this image from the NASA/ESA Hubble Space Telescope. The small galaxy consists of a diffuse band of stars containing red bubbles of gas that mark regions of recent star formation, and lies roughly 26 million light-years from Earth in the constellation Corvus. Appearing as just a small patch of stars, UGCA 307 is a diminutive dwarf galaxy without a defined structure — resembling nothing more than a hazy patch of passing cloud.

Despite being the scene of an impending stellar ‘death’, astronomers also look to Wolf-Rayet stars for insights into new beginnings. Cosmic dust is forming in the turbulent nebulas surrounding these stars, dust that is composed of the heavy-element building blocks of the modern Universe, including life on Earth.

As Jellyfish galaxies move through intergalactic space they are slowly stripped of gas, which trails behind the galaxy in tendrils illuminated by clumps of star formation. These blue tendrils are visible drifting below the core of this galaxy, and give it its jellyfish-like appearance. This particular jellyfish galaxy — known as JO201 — lies in the constellation Cetus, which is named after a sea monster from ancient Greek mythology.

The NASA/ESA Hubble Space Telescope had a ringside view of the space demolition derby.
The Hubble movie starts at 1.3 hours before impact. The first post-impact snapshot is 20 minutes after the event. Debris flies away from the asteroid in straight lines, moving faster than four miles per hour (fast enough to escape the asteroid’s gravitational pull, so it does not fall back onto the asteroid). The ejecta forms a largely hollow cone with long, stringy filaments.
At about 17 hours after the impact the debris pattern entered a second stage. The dynamic interaction within the binary system started to distort the cone shape of the ejecta pattern. The most prominent structures are rotating, pinwheel-shaped features. The pinwheel is tied to the gravitational pull of the companion asteroid, Didymos.
Hubble next captures the debris being swept back into a comet-like tail by the pressure of sunlight on the tiny dust particles. This stretches out into a debris train where the lightest particles travel the fastest and farthest from the asteroid. The mystery is compounded later when Hubble records the tail splitting in two for a few days.

Due to Gravitational lensing, this observation contains three different images of the same supernova-hosting galaxy, which you can see in closer detail here. Gravitational lensing occurs when a massive celestial body causes a sufficient curvature of spacetime to bend the path of light travelling past or through it, almost like a vast lens. In this case, the lens is the galaxy cluster RX J2129, located around 3.2 billion light-years from Earth in the constellation Aquarius.

This image is populated with a serene collection of elliptical and spiral galaxies, but galaxies surrounding the central cluster — which is named SPT-CL J0019-2026 — appear stretched into bright arcs, as if distorted by a gargantuan magnifying glass. This cosmic contortion is called gravitational lensing, and it occurs when a massive object like a galaxy cluster has a sufficiently powerful gravitational field to distort and magnify the light from background objects.

The largest survey of nearby galaxies in Webb’s first year of science operations is being carried out by the Physics at High Angular resolution in Nearby Galaxies (PHANGS) collaboration, involving more than 100 researchers from around the globe.
The team is studying a diverse sample of 19 spiral galaxies, and in Webb’s first few months of science operations, observations have been made of five of those targets, which are featured in this video. These galaxies are M74, NGC 7496, IC 5332, NGC 1365, and NGC 1433.

Bartmann (ESA/Webb) Music: Stellardrone – The Night Sky in MotionCan You Spot It?HubbleWebbESA2023-02-15 | Right in the middle of this image, nestled amongst a smattering of distant stars and even more distant galaxies, lies the newly discovered dwarf galaxy known as Donatiello II. If you cannot quite distinguish the clump of faint stars that is all we can see of Donatiello II in this image, then you are in good company. Donatiello II is one of three newly discovered galaxies that were so difficult to spot that they were all missed by an algorithm designed to search astronomical data for potential galaxy candidates. Even the best algorithms have their limitations when it comes to distinguishing very faint galaxies from individual stars and background noise. In these most challenging identification cases, discovery has to be done the old-fashioned way — by a dedicated human trawling through the data themselves.

DonatielloGalactic Crash CourseHubbleWebbESA2023-02-15 | A spectacular trio of merging galaxies in the constellation Boötes takes centre stage in this image from the NASA/ESA Hubble Space Telescope. These three galaxies, known to astronomers as SDSSCGB 10189, are set on a collision course and will eventually merge into a single larger galaxy, distorting one another’s spiral structure through mutual gravitational interaction in the process. An unrelated foreground galaxy appears to float serenely alongside the collision, and the smudged shapes of much more distant galaxies are visible in the background.
Music: Stellardrone - Billions and BillionsPan of Pandora’s ClusterHubbleWebbESA2023-02-15 | Astronomers estimate 50 000 sources of near-infrared light are represented in this image from the NASA/ESA/CSA James Webb Space Telescope. Their light has travelled through various distances to reach the telescope’s detectors, representing the vastness of space in a single image. A foreground star in our own galaxy, to the right of the image centre, displays Webb’s distinctive diffraction spikes. Bright white sources surrounded by a hazy glow are the galaxies of Pandora’s Cluster, a conglomeration of already-massive clusters of galaxies coming together to form a mega cluster. The concentration of mass is so great that the fabric of spacetime is warped by gravity, creating a natural, super-magnifying glass called a 'gravitational lens' that astronomers can use to see very distant sources of light beyond the cluster that would otherwise be undetectable, even to Webb.
