The venerable Hubble observatory is going strong despite its decades in space and the advent of next-generation successors

The James Webb Space Telescope has confirmed the most distant, early galaxy in the known universe. The new contender, MoM-z14, is visible just 280 million years after the Big Bang.

The Milky Way's Galactic Center and Bulge are shrouded in thick dust and tightly-packed with stars. It's a tough region to observe, but the Nancy Gracy Roman Space Telescope is built for the task. Its Galactic Bulge Time-Domain Survey will find more than 100,000 exoplanets, along with stars, black holes, neutron stars, and even rogue planets.

AI helped researchers probe the Hubble Space Telescope's archive to find strange celestial objects, including some indescribable by science.

The galaxy MoM-z14 could offer clues to what the universe looked like in its early infancy

Scientists continue to mine data gathered by NASA's Kepler Space Telescope, retired in 2018, and continue to turn up surprises. A new paper reveals the latest: a possible rocky planet slightly larger than Earth, orbiting a sun-like star about 146 light-years away. The candidate planet, HD 137010 b, might be remarkably similar to Earth, but it has one potentially big difference: It could be colder than perpetually frozen Mars.

Scientists analyzed more than 100 million image cutouts from a Hubble Space Telescope archive and found hundreds of previously undiscovered objects

Using a brand new data analysis tool, astronomers identified more than 800 strange and previously undocumented space objects.

A team of astronomers has employed a cutting-edge, artificial intelligence–assisted technique to uncover rare astronomical phenomena within archived data from NASA's Hubble Space Telescope. The team analyzed nearly 100 million image cutouts from the Hubble Legacy Archive, each measuring just a few dozen pixels (7 to 8 arcseconds) on a side. They identified more than 1,300 objects with an odd appearance in just two and a half days—more than 800 of which had never been documented in scientific literature.

Astronomers used AI to scan about 100 million Hubble image cutouts, finding 1,300 rare, odd objects in days, over 800 previously unreported.

Astronomers puzzled out minuscule distortions in images of faraway galaxies taken by JWST in order to chart the invisible

The Circinus Galaxy, a galaxy about 13 million light-years away, contains an active supermassive black hole that continues to influence its evolution. The largest source of infrared light from the region closest to the black hole itself was thought to be outflows, or streams of superheated matter that fire outward.

A spectacular new image from the James Webb Space Telescope reveals intricate structures inside the Helix Nebula, where a dying sunlike star is enriching the galaxy with the elements needed for life.

Gravitational lensing is a powerful tool that brings impossibly distant galaxies into reach. The JWST uses galaxy clusters and their overpowering to magnify background galaxies that are otherwise beyond our observational capabilities. One cluster, named MACS J1149.5+2223, is 5 billion light-years away and holds at least 300 galaxies, probably many more. It's been chosen as the JWST's Picture Of The Month.

For years, the James Webb Space Telescope has been spotting enormous black holes in the early universe that defy all expectations. Now, astronomers are finally deciphering the origins of these cosmic behemoths.

How do blue stragglers defy the aging that turns their mates red? Blue stragglers are found in ancient star clusters, where they outshine stars the same age, looking far bluer and younger than their true age. Astrophysicists have tried to understand blue stragglers for decades. New research using the NASA/ESA Hubble Space Telescope is finally revealing how these ageless stars come to be and why they thrive in quieter cosmic neighbourhoods.

Some stars appear to defy time itself. Nestled within ancient star clusters, they shine bluer and brighter than their neighbors, looking far younger than their true age. Known as blue straggler stars, these stellar oddities have puzzled astronomers for more than 70 years. Now, new results using the NASA/ESA Hubble Space Telescope are finally revealing how these "forever young" stars come to be and why they thrive in quieter cosmic neighborhoods.

The Helix Nebula is one of the closest and brightest planetary nebula. It's what's left of a dying star and has nothing to do with planets. Our Sun will end up as one of these sumptuous displays, and a new JWST image reveals even more detail in the stunning nebula.

This NASA/ESA/CSA James Webb Space Telescope Picture of the Month brings us a scene from the distant universe. Pictured here is the galaxy cluster MACS J1149.5+2223, or MACS J1149 for short, which is located about 5 billion light-years away in the constellation Leo.

A fresh look at the Helix Nebula captures new details of the cycle of stellar life and death

Baby pictures are some of a family's most cherished artifacts. The same thing can be said of the Hubble Space Telescope and the infant stars it immortalizes in its scientific portraits. But while we know how babies are conceived and how they form in great detail, the same can't be said for star formation.

Newly developing stars shrouded in thick dust get their first baby pictures in these images from NASA’s Hubble Space Telescope. Hubble took these infant star snapshots in an effort to learn how massive stars form. Protostars are shrouded in thick dust that blocks light, but Hubble can detect the near-infrared emission that shines through holes carved in the gas by the young stars themselves.

Researchers from the South Pole Telescope project team looked deep into the center of the Milky Way, discovering powerful, surprising bursts of light from two accreting white dwarf systems.

A Simon Fraser University cosmologist believes his team's new research may bring them a step closer to cracking one of science's biggest questions—the Hubble tension.

While this eerie NASA Hubble Space Telescope image may look ghostly, it's actually full of new life. Lupus 3 is a star-forming cloud about 500 light-years away in the constellation Scorpius.

One of the most stubborn issues in cosmology today concerns the universe's rate of expansion. Scientists know it's expanding, but defining the rate of that expansion is challenging. The rate of expansion is called the Hubble Constant, after American astronomer Edwin Hubble, who discovered in the 1920s that the universe is expanding.

Chinese researchers have braved the cold and harsh environment of Antarctica in order to get a unique view of star formation in the interstellar medium (ISM). The Chinese National Antarctica and Arctic Research Expedition (CHINARE) has managed to complete a study at Dome A—the highest ice dome on the Antarctic Plateau—and successfully collected submillimeter data to form a better understanding of carbon cycling in the ISM. Their research is published in Science Advances.

New photos show off NASA's newly constructed Roman Space Telescope, which will soon help researchers unravel the mysteries of the cosmos. Experts have also revealed when the next-gen spacecraft is set to launch and begin collecting data.

Researchers used the JWST to find a pair of strong gravitationally lensed Supernovae. They exploded billions of years ago, and their light is just reaching us now. Because of the lensing, we'll see multiple images of them, separated by years or decades. This could reveal the expansion rate of the Universe, and provide a solution to the Hubble Tension.

New Space is a term now commonly used around the rocketry and satellite industries to indicate a new, speed focused model of development that takes its cue from the Silicon Valley mindset of "move fast and (hopefully don't) break things." Given that several of the founders of rocketry and satellite companies have a Silicon Valley background, that probably shouldn't be a surprise, but the mindset has resulted in an exponential growth in the number of satellites in orbit, and also an exponential decrease in the cost of getting them to orbit.

New Space is a term now commonly used around the rocketry and satellite industries to indicate a new, speed focused model of development that takes its cue from the Silicon Valley mindset of “move fast and (hopefully don’t) break things.” Given that several of the founders of rocketry and satellite companies have a Silicon Valley background, that probably shouldn’t be a surprise, but the mindset has resulted in an exponential growth in the number of satellites in orbit, and also an exponential decrease in the cost of getting them to orbit. A new paper, recently published in pre-print form in arXiv from researchers at Schmidt Space and a variety of research institutes, lays out plans for the Lazuli Space Observatory, which hopes to apply that same mindset to flagship-level space observatory missions.

This new NASA Hubble Space Telescope image captures a jet of gas from a forming star shooting across the dark expanse. The bright pink and green patches running diagonally through the image are HH 80/81, a pair of Herbig-Haro (HH) objects previously observed by Hubble in 1995. The patch to the upper left is part of HH 81, and the bottom streak is part of HH 80.

The platypus is one of evolution's lovable, oddball animals. The creature seems to defy well-understood rules of biology by combining physical traits in a bizarre way. They're egg-laying mammals with duck bills and beaver-like tails, and the males have venomous spurs on their hind feet. In that regard, it's only fitting that astronomers describe some newly discovered oddball objects as "Astronomy's Platypus."

Astronomers spotted nine galaxies with characteristics that have never been seen as a collection before. It's possible this is a newly found type of star-forming galaxy.

Astronomers have uncovered the long-hidden cause behind Betelgeuse’s strange behavior: a small companion star carving a visible wake through the giant’s vast atmosphere. Using nearly eight years of observations from NASA’s Hubble Space Telescope and ground-based observatories, scientists detected swirling trails of dense gas created as the companion, called Siwarha, moves through Betelgeuse’s outer layers.

The silver lining is that there may be a privately funded alternative in the works.

Astronomers have revealed a new type of cosmic object called Cloud-9 — a dim, starless gas cloud anchored by a massive dark matter halo that may be the first-confirmed failed galaxy.

JWST peered at the glowing trail of stars left behind by a candidate runaway supermassive black hole deep in space, revealing new insights after other telescopes looked at the event.

Avi Loeb reveals 'puzzling' triple jets on interstellar comet 3I/ATLAS.

Astronomers tracking a nearby star system thought they had spotted an exoplanet reflecting light from its star. Then it vanished. Even stranger, another bright object appeared nearby. After studying years of Hubble Space Telescope data, scientists realized they were not seeing planets at all, but the glowing debris left behind by two massive collisions between asteroid-sized bodies.

Hubble's latest images of interstellar comet 3I/ATLAS reveal sustained, jet-like eruptions and a carbon dioxide-rich coma that challenge existing comet physics, offering a rare insight into material from beyond the Solar System.

A newly discovered exoplanet is rewriting the rules of what planets can be. Orbiting a city-sized neutron star, this Jupiter-mass world has a bizarre carbon-rich atmosphere filled with soot clouds and possibly diamonds at its core. Its extreme gravity stretches it into a lemon shape, and it completes a full orbit in under eight hours. Scientists are stunned — no known theory explains how such a planet could exist.
