13,000-Year-Old Cosmic Airburst Triggered ‘Impact Winter’ and Mass Extinction, Research Suggests
New research points to fragments of a comet exploding over North America approximately 13,000 years ago, sparking firestorms and rapid cooling that could have contributed to the extinction of mammoths. Scientists report finding telltale “shocked” quartz grains at classic Clovis sites dating to the Younger Dryas boundary, evidence of intense he...

JWST Spots Most Distant Supernova Ever, From 730 Million Years After Big Bang
Scientists have confirmed the most distant supernova ever observed, exploding just 730 million years after the Big Bang. Detected through a powerful gamma-ray burst and later verified by the James Webb Space Telescope, the event offers a rare glimpse of the deaths of the universe’s first stars during the era of reionisation and challenges expecta...

Astronomers Witness Longest-Lasting Gamma-Ray Burst in History, 8 Billion Light-Years Away
A gamma-ray burst lasting over seven hours was recorded 8 billion light-years away, revealing a rare type of cosmic explosion and challenging current astrophysics models.

Interstellar Comet 3I/ATLAS Photographed Beside Distant Galaxy in Rare Cosmic Shot
A new image of interstellar comet 3I/ATLAS captures its glowing tails and a distant barred spiral galaxy, creating a dramatic cosmic overlap. Astronomers say the comet’s unusual features remain natural despite online speculation. With its closest Earth approach in December, researchers are preparing for sharper spacecraft images expected to revea...

Astronomers Observe Rare Supernova–Black Hole Interaction in Early Stages
In a groundbreaking discovery, astronomers observed SN 2023zkd, a supernova that may have been triggered by close interaction with a black hole. Featuring unusual brightness peaks and extended pre-explosion activity, the event offers new insights into star black hole dynamics. Real-time AI detection played a key role, and upcoming surveys promise t...

Brightest Gamma-Ray Burst Ever Observed Reveals Cosmic Secrets
On October 9, 2022, astronomers detected GRB 221009A, the most powerful gamma-ray burst ever recorded, earning the nickname “BOAT” (Brightest Of All Time). This rare, once-in-10,000-year event came from a galaxy 2 billion light-years away and temporarily blinded gamma-ray detectors. It revealed new insights into stellar death, as the associated...

Astronomers Capture First-Ever Image of a Dead Star That Exploded Twice in Rare Supernova Event
Astronomers have captured the first-ever image of a white dwarf star undergoing a rare double-detonation supernova. Using the Very Large Telescope, the team revealed that such explosions can occur without a star reaching the Chandrasekhar limit. The findings, published in Nature Astronomy, could reshape existing theories about stellar death and imp...

Supernovas May Have Triggered Deadly Ancient Climate Shifts, and They Could Happen Again
New research links nearby supernovas to drastic shifts in Earth’s ancient climate. These cosmic explosions may have eroded the ozone layer, triggered global cooling, and even caused mass extinctions. Tree ring data supports the theory, raising concerns that future stellar events, like the expected Betelgeuse explosion, could again pose serious at...

Astronomers Discover Most Powerful Cosmic Explosions Since the Big Bang
Astronomers have discovered extreme nuclear transients — rare and powerful explosions caused by stars being torn apart by supermassive black holes. These events, brighter and longer-lasting than supernovae, were observed using data from Gaia and ZTF. As the most energetic cosmic outbursts since the Big Bang, they offer valuable insights into blac...

Einstein Probe Detects Mysterious X-ray Flare with Record-Long Emission
An international team of astronomers has detected a peculiar fast-evolving X-ray transient, EP241021a, using China’s Einstein Probe. Unveiled in a May 12 arXiv paper, this transient stood out due to its long-lasting emissions lasting over 79 days—unprecedented among FEXTs. EP241021a also produced optical and radio emissions, suggesting a multi-...

Supernova Remnants Found in Oceanic Samples, Scientists Look to Moon
Scientists have identified supernova debris in deep-sea sediments, including a rare plutonium isotope linked to a kilonova. Researchers believe a neutron star collision occurred nearly 10 million years ago, scattering radioactive material across space. To validate this theory, they plan to analyze lunar soil, which remains undisturbed by Earth's ge...

Unusual X-ray Flash in Large Magellanic Cloud Puzzles Astronomers
A brief yet intense X-ray flash, XRT 200515, was detected in NASA's Chandra telescope data from 2000. The signal, originating from the Large Magellanic Cloud, has left scientists debating its cause. Possible explanations include a neutron star pulling in gas from a companion star or a powerful flare from a distant magnetar. Researchers also specula...

Hubble Spots Distant Supernova in Gemini, Enhancing Cosmic Distance Studies
The NASA/ESA Hubble Space Telescope has captured a stunning image of SN 2022aajn, a Type Ia supernova in the constellation Gemini. Located 600 million light-years away, the explosion was first detected in November 2022. Type Ia supernovae serve as essential cosmic distance markers due to their predictable brightness. Hubble’s observations, part o...
