Deep in the frozen heart of Antarctica, the South Pole Telescope has been watching one of the most extreme neighbourhoods in our Galaxy, and it's just caught something extraordinary happening there. Astronomers have detected powerful stellar flares erupting from stars near the supermassive black hole at the centre of the Milky Way. These aren't your average stellar flares, we're talking about energy releases so intense they make our Sun's most dramatic outbursts look like flickering candles.

The Monk Who Recognised Halley's Comet First
When Halley's Comet blazed across English skies in April 1066, an elderly Benedictine monk named Eilmer watched from Malmesbury Abbey with growing recognition. "You've come, have you?" he reportedly said, crouching in terror at the glowing apparition. "You've come, you source of tears to many mothers." But Eilmer's words carried weight beyond mere dread, he realised he had seen this exact comet before, during its previous appearance in 989 when he was just a young man.
Astronomers discover the 'growing pains' of teenage exoplanets
"We've often seen the 'baby pictures' of planets forming, but until now, the 'teenage years' have been a missing link."
Mapping the Invisible
Dark matter doesn't emit light, it doesn't absorb light and it doesn't even block it, passing through ordinary matter like a ghost through walls (I’m very proud of that sentence.) Yet this invisible substance makes up roughly 85% of all matter in the universe, and its gravitational influence has shaped everything from galaxy clusters millions of light years across down to the rocky planet beneath our feet.
Researchers Use AI To Find Astronomical Anomalies Buried In Archives
AI faces daily criticism from people worried about its ill-effects. But the type of AI that draws this ire are Large Language Models (LLMs). There are other types of AI with specialized functions that don't make it onto the front pages. Combing through vast troves of astronomical data is a perfect task for AI that is unlikely to be replicated by human minds.
NASA moves critical fueling test for Artemis 2 moon rocket up to Jan. 31

What role will F-15 jets play in the future of supersonic flight?
This Rapidly Growing Black Hole Is Challenging Super-Eddington Accretion
In recent years, astrophysicists have discovered supermassive black holes (SMBH) in the early Universe that are much larger than they should be. Black hole growth is restrained by the Eddington Mass Limit, a cap on the growth rate of black holes. But objects can exceed this limit in certain circumstances, and that's called super-Eddington accretion. san Super-Eddington accretion explain these early SMBH?

The Rubin Observatory Will Rapidly Detect More Supernovae
In our galaxy, a supernova explodes about once or twice each century. But historical astronomical records show that the last Milky Way core-collapse supernova seen by humans was about 1,000 years ago. That means we've missed a few.

1400 quirky objects found in Hubble's archive
A team of astronomers have used a new AI-assisted method to search for rare astronomical objects in the Hubble Legacy Archive. The team sifted through nearly 100 million image cutouts in just two and a half days, uncovering nearly 1400 anomalous objects, more than 800 of which had never been documented before.

The HWO Must Be Picometer Perfect To Observe Earth 2.0
Lately we’ve been reporting about a series of studies on the Habitable Worlds Observatory (HWO), NASA’s flagship telescope mission for the 2040s. These studies have looked at the type of data they need to collect, and what the types of worlds they would expect to find would look like. Another one has been released in pre-print form on arXiv from the newly formed HWO Technology Maturation Project Office, which details the technology maturation needed for this powerful observatory and the “trade space” it will need to explore to be able to complete its stated mission.
