Planet hunters and stargazers will both benefit from the Euclid space telescope's newest image, which was released after 26 hours of deep-space observations.

Astronomers using NASA's Hubble Space Telescope have found something they never expected—ultraviolet light from a galaxy that existed just 1.4 billion years after the Big Bang. That galaxy contains tightly clustered young stars that produce ionizing light capable of transforming the opaque, neutral gas within and immediately around the galaxy, clearing our view. This suggests that similar galaxies in the early universe were responsible for clearing the neutral fog of hydrogen gas that once filled the cosmos.

Finding life beyond our solar system is a major goal of modern astronomy. NASA's planned Habitable Worlds Observatory (HWO) aims to take direct images of Earth-sized planets around stars other than our sun. This task, however, is extraordinarily difficult, given that these planets are roughly 10 billion times fainter than their host stars. To detect them, scientists must find ways to suppress nearly all of the nearby starlight, which would otherwise overwhelm the faint planetary signal.

This NASA Hubble Space Telescope image features a galaxy cluster called CL0016+1609, or MACS J0018.5+1626, that is very bright at X-ray wavelengths and is one of the most extensively studied clusters at X-ray and radio wavelengths. X-ray observations of this cluster revealed that it is two clusters merging along our line of sight.

Construction of the Deep Synoptic Array is about to start in rural Nevada. It will reveal untold galaxies in stunning detail and help explain how they form and grow

We're still in the definition phase of the Habitable Worlds Observatory (HWO), but it seems like every week a new research group comes out with a paper helping to shape what is becoming one of the most important space telescopes of the 2040s. A new paper posted to the arXiv preprint server from a team of researchers led by Daniel Jaffe of the University of Texas at Austin contributes to this ongoing definition work by arguing that it's time HWO adopted a high-resolution near-IR spectroscopy capability—which sounds great in practice, but so far hasn't been attempted because of technological limitations. But, according to the paper, two recent inventions finally make a working version of an extremely high-resolution exoplanet hunter viable.

Author(s): Israel Gabay, Omer Luria, Edward Balaban, Amir D. Gat, and Moran BercoviciLarge-aperture telescopes are currently limited by launch vehicle constraints. The Fluidic Telescope (FLUTE) concept seeks to overcome this by using liquid mirrors which, in microgravity, naturally relax into a precise spherical shape. However, necessary telescope maneuvers subject the liquid to body forces that perturb this interface. This study provides an experimentally validated analytical model for such liquid dynamics by solving for the non-self-adjoint problem of a thin liquid film pinned in a circular domain. Using the model to simulate decades of operation, we show that while edge disturbances build up, the inner 80% of the aperture remains optically precise for over 20 years. [Phys. Rev.

Researchers using two of humanity's most powerful observatories—NASA's James Webb and Hubble Space Telescopes—have definitively shown that Terzan 5 is not a globular star cluster, as it was once classified, offering new insight into how galaxies like our own form and evolve over time.

When someone asks me what originally got me interested in space exploration, my answer is always the same - the Hubble Deep Field. That image, taken in 1995, came out when I was in middle school, and had an everlasting impact on my sense of place in the universe. It’s since been improved upon by various other images, and even last week the Hubble team released yet another jaw-dropping image of the galaxy cluster MACS0329-0211 which recaptures some of the magic of that original image, and still provides the same sense of scale that never seems to truly fade once you come to terms with it. While the original Hubble Deep Field was a blind experiment to see what lay in a seemingly empty patch of sky, this new image comes from the targeted Cluster Lensing and Supernova survey with Hubble (CLASH) program, focusing on the dynamics of a specific

Astronomers using the MeerKAT radio telescope in South Africa have discovered the most distant hydroxyl megamaser ever detected, opening a new radio astronomy frontier. A hydroxyl megamaser is a natural space laser, and this one is located in a violently merging galaxy more than 8 billion light-years away.

It’s 2134, and humanity has finally embraced green technologies while ridding the Earth of harmful fossil-burning technologies, most notably gasoline, wood, coal, and oil. As a result, soot has been rendered obsolete, and all commercial products from soot, including shoes, wires, computer products, and eye products, are now produced from eco-friendly technologies. However, the uber-rich who still fancy non-eco-friendly products are willing to pay soot’s weight in gold for it. Therefore, the Exoplanet Research Corporation outfits its best ship to search for soot-enriched exoplanet atmospheres.

This March 20, 2026, image of Messier 64, or the Black Eye Galaxy, is a composite view from NASA's Hubble Space Telescope and James Webb Space Telescope. It shows Messier 64 captured at near- and mid-infrared wavelengths by Webb, while Hubble's image shows the galaxy in ultraviolet, visible, and near-infrared light.

Looking somewhat like a swarm of bees returning to their hive, this NASA Hubble Space Telescope image features the galaxy cluster MACS0329-0211. Galaxy clusters like MACS0329-0211 are important signposts in the story of how the structure of the universe evolved, and are the ultimate telescopic lenses, placing gravitationally lensed galaxies from the earliest stages of the universe into our view.

Astronomers have revealed distinct differences in atmospheric conditions between the morning and evening transition zones of the ultra-hot gas planet WASP-121 b, which separate day from night, commonly called terminators. This achievement was only possible due to the unmatched sensitivity of the James Webb Space Telescope (JWST).

A new theoretical study may have cracked one of the most puzzling discoveries of the James Webb Space Telescope (JWST): Little Red Dots, spotted across the early universe. The paper, posted to the arXiv preprint server on May 29, argues that these objects could be black holes caught in rare, violent bursts of feeding at a rate exceeding theoretical limits.

A lightweight new X-ray telescope could finally give scientists something they’ve never had before: a complete chemical map of the Moon. Researchers used detailed mission simulations to show that a compact telescope orbiting the Moon could identify key elements across the entire lunar surface, helping reveal how the Moon formed and evolved.

JWST found a black hole hiding in a galaxy more than 10 billion light-years away from Earth, and used a cosmic magnifying glass to determine its mass.

The most distant, nearly invisible dormant black hole has been detected and "weighed" by an international team of astronomers that includes researchers from UCL. The study, published in Science, identified a dormant black hole at the heart of a galaxy known as MRG-M0138 located over 10 billion light years away. It is the most distant dormant black hole yet detected, 15 times farther away than the previous record.

Our telescope expert chose the Celestron NexStar 8SE as our best overall telescope, and now, with $200 off, it makes this versatile telescope excellent value for money ahead of Prime Day.

Ever since the JWST revealed a population of SMBH in the early universe that were overmassive, scientists have been working hard to explain them. These black holes existed when the universe was only about 2 billion years old, during Cosmic Noon, and according to our models of black hole growth, there simply wasn't enough time for them to grow so massive.

NASA has completed its final inspection of the primary mirror on the Roman Space Telescope, which measures 2.4 meters (7.9 feet) in diameter and contains a layer of silver hundreds of times thinner than a human hair, at 400 nanometers.

The JWST found an abundance of overmassive black holes at high redshifts, pushing the limits of black hole (BH) science in the early Universe. Results have claimed that these BHs are significantly more massive than expected from the BH mass-host galaxy stellar mass relation derived from the local Universe. But new research shows they were just outliers in the normal range of masses that don't require any special causes.

The focus of this NASA/ESA Hubble Space Telescope image is an active spiral galaxy on a journey lasting hundreds of millions of years. The galaxy Messier 88 (M88), also known as NGC 4501, is located about 63 million light-years away in the constellation Coma Berenices (Berenice's Hair).

A stunning spiral galaxy called Messier 88 is racing through the crowded Virgo Cluster on a journey that will dramatically reshape its future. At its heart lies a supermassive black hole about 100 million times the mass of the Sun, while its graceful spiral arms sparkle with young star clusters and dark clouds of dust. But as M88 plunges deeper into the cluster over the next few hundred million years, powerful forces will strip away much of the gas it needs to create new stars.

NASA’s Roman Space Telescope could revolutionize the search for alien worlds by discovering around 100,000 exoplanets—far more than all previous missions combined. It will look deep into unexplored parts of the Milky Way, helping scientists compare planetary systems across very different galactic environments. The mission will also uncover rare Earth-sized planets, study thousands of exotic alien atmospheres, and provide a treasure trove of data that could reshape our understanding of how planets form.

It’s June 2027, and you’re fresh off defending your PhD studying the direct imaging of exoplanets while starting your postdoctoral journey at NASA Jet Propulsion Laboratory. The trauma of eating ramen and living off a sub-living wage for the last five years of your life is still fresh in your brain. But you’re excited to finally get your real career started with funding you received for viewing time on the much-anticipated Nancy Grace Roman Space Telescope (Roman for short). You begin to download the first set of data as your eyes tear up knowing your entire journey in research and academia is about to be worth it.

It’s 2165, and methane is in high demand, especially after the Titan Treaty of 2145 made it illegal to harvest methane from Saturn’s moon, Titan. But the advent of interstellar travel has made exoplanetary exploration far easier, enabling corporations to identify and harvest methane from exoplanets. However, it’s far cheaper and easier to harvest methane from exoplanets with reasonable (also called temperate) temperatures, because it means higher quantities of methane. The Exoplanet Exploration Corporation decides to send its first ship to one such exoplanet loaded with methane that could bring their quarterly financial statements back into the green.

Astronomers using the James Webb Space Telescope (JWST) have discovered a stellar bar in GN20, a massive galaxy seen just 1.5 billion years after the Big Bang. The new paper was submitted to the preprint server arXiv on May 14.

The James Webb telescope peered into an ancient spot of light, and found it to be the most metal-poor galaxy in the early universe.

Messier 88 is an active galaxy with a central supermassive black hole that is gobbling up gas and dust

There's a planet out there called LHS 3844 b, orbiting a star about 48 light-years away. The Transiting Exoplanet Survey Satellite (TESS) found it in 2018 when the planet transited across the face of its star. The James Webb Space Telescope zxeroed in on the planet and found it to be a barren, rocky place with no atmosphere.

Two pairs of 'rogue' Jupiter-size, planet-like objects have been found in a large star-forming region in the Milky Way, a new study claims. The findings suggest the weird objects actually do exist, and are not an illusion.

Astronomers weighed a black hole in a "little red dot" discovered by the James Webb telescope. They found it to be so overmassive that it may have formed before its host galaxy had a chance to develop.

This NASA Hubble Space Telescope image features the dwarf irregular galaxy ESO 490-017, roughly 12,000 light-years in diameter and some 23 million light-years away in the constellation Canis Major. The galaxy's low surface brightness makes it appear as a faint, starry swarm behind brighter foreground stars that are easily recognized by their diffraction spikes. Numerous red, orange, and beige dots are distant galaxies peppering the black background, many exhibiting distinct spiral structure.

A giant planet nearly 700 light-years away has a bizarre daily weather cycle where mineral clouds appear every morning and vanish by nightfall. Using the James Webb Space Telescope, astronomers discovered that WASP-94A b’s mornings are filled with clouds made of rock-like minerals, while its evenings are surprisingly clear. The finding gave scientists their clearest look yet into the planet’s atmosphere and revealed it’s far more Jupiter-like than previously believed.

NASA’s Fermi telescope has detected what may be the first confirmed gamma-ray signal from a superluminous supernova — one of the most extreme explosions in the universe. Scientists believe the blast was powered by a rapidly spinning magnetar, an exotic neutron star with unbelievably strong magnetic fields. The event, called SN 2017egm, erupted 440 million light-years away and may help explain why some supernovae become extraordinarily bright.

Look closely at this image from NASA's Hubble Space Telescope and you'll see galaxies of various shapes and sizes clustered together toward the center-left of the image. A few foreground stars shine brightly and are easily distinguished by the spikes that appear to extend outward from each star. These spikes, called diffraction spikes, are the result of how point sources of light (such as stars) bend, or diffract, around the supports for Hubble's secondary mirror.

Neptune has a complicated life story, and its moon Nereid might be the only one left standing from the planet’s multibillion-year history.

An out-of-this-world weather report from NASA’s James Webb Space Telescope reveals how clouds move across a giant planet hundreds of light-years from Earth

The Haystack 37m Telescope has been a landmark in radio astronomy and radar studies of the solar system since its first light in 1964. Over the following four decades, it supported NASA's Apollo landings on the moon, made planetary radar maps of the surface of Venus, contributed to experimental tests of Einstein's general relativity, supported the development of VLBI, and conducted foundational studies of quasars and star-forming regions.

One of the most puzzling findings from the JWST's observations of the early universe is the size of black holes. According to our understanding of black hole growth, these early black holes are far more massive than expected. Astronomers expected the unexpected from JWST, and it has delivered. Now the challenge is to update models of the universe to include these new observations.

A new European-led telescope could map the dusty, hidden half of the universe, all without using fossil fuels. If you have ever seen the Milky Way in the night sky, you probably noticed that it looks cloudy. That is because towards the center of our galaxy, and of most galaxies, there are vast amounts of dust that make it hard to see what is going on.

Ever since the JWST found over-massive black holes in the early Universe, researchers have been trying to understand them. Theory showed that black holes and their galaxies grew in synchronization with each other. That can't explain the JWST's findings, but new research might.

The new image shows the galaxy NGC 1266, a middle-aged object with a clutch of young stars that likely collided with another, smaller galaxy 500 million years ago

NASA’s Nancy Grace Roman Space Telescope is now aiming for an earlier launch in September 2026. Designed to explore dark matter, dark energy, and distant exoplanets, the telescope will capture massive, ultra-detailed surveys of the cosmos using infrared vision. Scientists expect Roman to uncover hundreds of millions of galaxies and possibly even entirely new cosmic phenomena. Its enormous data archive could reshape astronomy for decades.

This NASA Hubble Space Telescope image reveals an enigmatic galaxy with a bright center and a face that hints at spiral structure, yet it holds no obvious spiral arms. Reddish-brown clumps and filaments of dust partially obscure the galaxy's full face, while red, blue, and orange light from distant galaxies shines through its diffuse outer regions and dots the inky-black background.

Astronomers may have found an explanation for one of the biggest mysteries revealed by the James Webb Space Telescope (JWST): why so many galaxies in the early universe appear unexpectedly bright in ultraviolet light. The new study, posted to the arXiv preprint server on May 11, suggests that galaxies more than 13 billion years ago were filled with an unusual kind of dust produced directly by supernova explosions, which could help explain why galaxies appeared so bright.

Using the James Webb Space Telescope, astronomers have created the most detailed map of the cosmic web ever.

NASA’s Roman Space Telescope could expose a vast hidden population of neutron stars lurking unseen across the Milky Way. By detecting subtle shifts in starlight caused by gravity, the mission may identify and even weigh isolated neutron stars that are otherwise impossible to see. Scientists hope the discoveries will reveal how these extreme objects are born and why they are blasted through space at incredible speeds.

One of the core community surveys of NASA’s Nancy Grace Roman Space Telescope, the Galactic Bulge Time-Domain Survey, is expected to locate over a thousand exoplanets that orbit far away from their stars, beyond the orbital distance of Earth from the Sun. Although Roman hasn’t launched yet, astronomers already are gathering useful supporting data by utilizing NASA's Hubble Space Telescope, which could assist astronomers in analyzing Roman data.

A blurry new photo captured by the Green Bank Telescope in West Virginia shows Artemis II's Orion capsule circling the moon more than 200,000 miles away, making it a candidate for the longest-distance image of humans ever taken from Earth.

Extremely powerful quasars in the early Universe drove star-forming gas out of their galaxies. These Super-quasars are behind the JWST's puzzling early Universe observations.

Seen just 800 million years after the big bang, an object called LAP1-B is a galactic building block that seems to hold some of the first stars to ever shine

Using data from NASA's James Webb Space Telescope (JWST), astronomers led by researchers at the University of California, Riverside have produced the most detailed map of the cosmic web ever made, tracing the network of galaxies all the way back to when the universe was one billion years old.

Astronomers using NASA’s James Webb Space Telescope have created the clearest map yet of the universe’s “cosmic web” — the enormous hidden structure that connects galaxies across space. By analyzing more than 164,000 galaxies through the massive COSMOS-Web survey, researchers were able to trace this vast network back to when the universe was just a billion years old.

Hubble has revealed a giant planet-forming disk unlike anything astronomers have seen before. Nicknamed “Dracula’s Chivito,” the enormous structure appears turbulent and oddly lopsided, with towering filaments visible on only one side. The disk contains enough material to potentially create multiple giant planets, making it a fascinating new laboratory for studying how planetary systems are born.

The Milky Way's galactic bulge, the bulbous region that surrounds the galactic center, contains a dense collection of stars, planets, and other free-floating objects. This region has been studied for decades with numerous ground-based and space-based telescopes, including NASA's Hubble and James Webb space telescopes.

Astronomers have discovered two early-universe galaxies where the central black holes appear to have grown far faster than their host galaxies. Observations with the James Webb Space Telescope (JWST) reveal that the black holes in these galaxies, seen just 800 million years after the Big Bang, are significantly more massive relative to their host galaxies, as opposed to what astronomers see in the nearby universe. The study is published on the arXiv preprint server.

A spiral galaxy seen close up and tilted at an angle, so that its disc fills the view from corner to corner. Its disc is yellow near to the centre and pale blue farther out, showing cooler and hotter stars, respectively. Thin brown clouds of dust, glowing pink spots of star formation, and sparkling blue patches filled with star clusters swirl through the galaxy. Behind it, small orange dots are very distant galaxies.

A peculiar object dubbed an 'X-ray dot' could help solve the mystery of the 'little red dots' discovered by the James Webb Space Telescope.
