Hunting for the Lunar Debris Hiding Near Earth

By Andy Tomaswick - February 10, 2026

The Moon has a long history of being smacked by large rocks. Its pock-marked, cratered surface is evidence of that. Scientists expect that, as part of those impacts, some debris would be scattered into space - and that we should be able to track it down. But so far, there have been startlingly few discoveries of these Lunar-origin Asteroids (LOAs) despite their theoretical abundance. A new paper from Yixuan Wu and their colleagues at Tsinghua University explains why - and how the Vera Rubin Observatory might help with finding them.

Review: Dwarf Lab's New Dwarf Mini Smart Telescope

By David Dickinson - February 05, 2026

Telescopes are getting smaller. It’s strange to think: smartscopes have been with us for over half a decade now. Since 2020, we’ve tested units from Vaonis, Unistellar and more. In a short time, these smartscopes have revolutionized amateur astronomy, putting deep-sky imaging within reach of causal users. Recently, we had a chance to put Dwarf Lab’s latest unit the Dwarf Mini through its paces.

Turning Forgotten Telescope Data into New Discoveries

By Andy Tomaswick - February 05, 2026

Astronomers have been collecting data for generations, and the sad fact is that not all of it has yet been fully analyzed. There are still discoveries hiding in the dark recesses of data archives strewn throughout the astronomical world. Some of them are harder to access than others, such as actual physical plates containing star positions from more than a hundred years ago. But as more and more of this data is archived, astronomers also keep coming up with ever more impressive tools to analyze it. A recent paper from Cyril Tasse of the Paris Observatory and his co-authors, published recently in Nature Astronomy describes an algorithm that analyzes hundreds of thousands of previously unknown data points in radio telescope archives - and they found some interesting features in it.

The Monk Who Recognised Halley's Comet First

By Mark Thompson - January 27, 2026

The comet bearing Edmond Halley's name may have been misnamed! New research from Leiden University reveals that an 11th Century English monk recognised the famous comet's periodicity centuries before the British astronomer. Eilmer of Malmesbury witnessed the comet's appearances in both 989 and 1066, linking the two observations and understanding they represented the same celestial visitor returning after decades, a realisation documented by the medieval chronicler William of Malmesbury but overlooked by scholars until now. The discovery challenges whether history's most famous comet should continue bearing Halley's name when a Benedictine monk beat him to the discovery by more than 600 years.

Asteroid 2024 YR4 Has a 4% Chance of Hitting the Moon. Here’s Why That’s a Scientific Goldmine.

By Andy Tomaswick - January 27, 2026

There’s a bright side to every situation. In 2032, the Moon itself might have a particularly bright side if it is blasted by a 60-meter-wide asteroid. The chances of such an event are still relatively small (only around 4%), but non-negligible. And scientists are starting to prepare both for the bad (massive risks to satellites and huge meteors raining down on a large portion of the planet) and the good (a once in a lifetime chance to study the geology, seismology, and chemical makeup of our nearest neighbor). A new paper from Yifan He of Tsinghua University and co-authors, released in pre-print form on arXiv, looks at the bright side of all of the potential interesting science we can do if a collision does, indeed, happen.

NASA's Webb Telescope Peers Into the Heart of the Circinus Galaxy

By Matthew Williams - January 26, 2026

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.

Probing the Mysteries of the Solar Corona with ESA’s Proba-3

By David Dickinson - January 22, 2026

Some really unique science can be done during a total solar eclipse. Totality is the one time we can see the elusive corona of the Sun, the pearly white segment of our host star’s lower atmosphere where space weather activity originates. The trouble is, totality is fleeting. What researchers really need are eclipses on demand. ESA’s innovative Proba-3 mission does just that, by making use of a free-flying occulting disk. Launched in late 2024, we’re now seeing some unique science and images from the space observatory.

Astronomers Spot a Barred Spiral Galaxy That Existed Just 2 Billion Years After the Big Bang

By Matthew Williams - January 11, 2026

Astronomers have uncovered a barred spiral galaxy that existed over 2 billion years after the Big Bang, potentially making it the earliest barred spiral galaxy ever observed.

NASA Releases the Long-Awaited Video of Kepler's Supernova Remnant

By Matthew Williams - January 08, 2026

A new video shows the evolution of Kepler’s Supernova Remnant using data from NASA’s Chandra X-ray Observatory captured over more than two and a half decades.

X-Ray Spectra Could Help Reveal Dark Matter in Galaxy Clusters

By Matthew Williams - January 07, 2026

A study published in the Astrophysical Journal Letters demonstrates that decaying dark matter (DDM) can potentially be detected in unidentified X-ray emission lines in the spectra of galaxy clusters.

By Jove: Jupiter Reaches Opposition for 2026

By David Dickinson - January 07, 2026

It was a question I heard lots this past weekend. “What’s that bright star near the Full Moon?” That ‘star’ was actually a planet, as Jupiter heads towards opposition rising ‘opposite’ to the setting Sun this coming weekend. This places the King of the Planets high in the northern sky, in the same general spot the Full Moon occupies in January.

Astronomers Discover a Bright Supernova Using Gravitational Lensing for the First Time

By Matthew Williams - January 06, 2026

An international team of astronomers using a combination of ground-based telescopes, including the W. M. Keck Observatory on Maunakea, Hawaiʻi Island, has discovered the first-ever spatially resolved, gravitationally lensed superluminous supernova. The object, dubbed SN 2025wny, offers a rare look at a stellar cataclysm from the early Universe and provides a striking confirmation of Einstein’s theory of general relativity.

Inside the Massive Radio Search of Our Newest Interstellar Guest

By Andy Tomaswick - January 06, 2026

It feels like every week now we’re writing a new article about how 3I/ATLAS is not an alien technology. But it’s worth re-iterating, and perhaps taking a look at the methodology we used to prove that statement. A new paper, available in pre-print form on arXiv from Sofia Sheikh of the SETI Institute and her co-authors, details how one specific instrument - the Allen Telescope Array (ATA) - contributed to that effort.

The Quadrantid Meteors and Earth at Perihelion Usher in the New Skywatching Year

By David Dickinson - January 02, 2026

It sneaks up on us, every annual flip of the calendar into the new year. If skies are clear, keep an eye out for the brief but strong Quadrantid meteors this weekend. The Quadrantids or ‘Quads’ have a brief but strong annual peak just after New Year’s Day. This also makes the shower notoriously elusive for observers.

Europa Clipper Reveals a New Perspective on Comet 3I/ATLAS

By Andy Tomaswick - December 30, 2025

Researchers have been trying to look at interstellar object 3I/ATLAS from every conceivable angle. That includes very unconventional ones. Recently, while 3I/ATLAS passed out of view of the Earth, it moved into a great vantage point for one of our interplanetary probes. Europa Clipper, whose main mission is to explore Jupiter’s active moon, turned its gaze during its six year journey back towards the center of the solar system and observed 3I/ATLAS as it was reaching its perihelion, and out of sight from the Earth.

NASA’s SPHEREx Observatory Completes Its First Map of the Cosmos in 102 Infrared Wavelengths

By Matthew Williams - December 27, 2025

Launched in March, NASA’s SPHEREx space telescope has completed its first infrared map of the entire sky in 102 colors. This map will enable 3D distance measurements to other galaxies and allow astronomers to measure the influence of Cosmic Inflation on the large-scale structure of the Universe.

Top Astronomical Events to Watch For in 2026

By David Dickinson - December 26, 2025

Ready for another amazing year of skywatching? 2025 was a wild year, with a steady parade of comets knocking on naked eye visibility, and one extra special interstellar comet, 3I/ATLAS. The sky just keeps on turning into 2026. Watch for mutual eclipse season for the major moons of Jupiter, as the moons pass one if front of the other. The ongoing solar cycle is also still expected to be active into 2026, producing sunspots space weather and more. And (finally!) we’ll see the return of total solar eclipses on August 12th, as umbral shadow of the Moon crosses Greenland, Iceland and northern Spain.

ESA's JUICE Mission Reveals More Activity from 3I/ATLAS

By Matthew Williams - December 21, 2025

During November 2025, ESA’s Jupiter Icy Moons Explorer (JUICE) used five of its science instruments to observe 3I/ATLAS. The instruments collected information about how the comet is behaving and what it is made of.

Comet 3I/ATLAS Has A Green Glow In New Color Images From Gemini North

By Evan Gough - December 17, 2025

Gemini North captured new images of Comet 3I/ATLAS after it reemerged from behind the Sun on its path out of the Solar System. The data were collected during a Shadow the Scientists session — a unique outreach initiative that invites students around the world to join researchers as they observe the Universe on the world’s most advanced telescopes.

Hubble Catches Another Glimpse of 3I/ATLAS

By Matthew Williams - December 12, 2025

The NASA/ESA Hubble Space Telescope reobserved interstellar comet 3I/ATLAS on 30 November with its Wide Field Camera 3 instrument. At the time, the comet was about 286 million km from Earth. Hubble tracked the comet as it moved across the sky.
