"Bashed With Gun, I Played Dead": Israeli Survivor Narrates Hamas Attack
On October 7, 2023, the world watched in horror as Hamas launched a brutal attack on Israel, killing around 1,200 people and taking 251 hostages.

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...

PSR J0922+0638 Pulsar Keeps Glitching Every 550 Days, Scientists Are Intrigued
PSR J0922+0638, an ultradense neutron star, shows puzzling rotational glitches every 550 days. Using 22 years of radio data, scientists detected both abrupt and slow changes in its spin. These may be linked to magnetic field cycles or superfluid dynamics deep inside the star. However, the exact cause remains a mystery, demanding continued long-term...

How The Largest Black Hole Merger In History Challenges Its Physics
Astronomers have detected the largest black hole merger ever, and it has challenged their understanding of such formations.

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...

Astronomers Discover a Gigantic Supernova Remnant in the Large Magellanic Cloud
Veliki is a newly discovered, massive supernova remnant in the Large Magellanic Cloud, observed through a global collaboration using multiwavelength astronomy tools. Estimated to be 45,000 years old, Veliki showcases complex shell structures and highly unusual radio properties.

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...

Astronomers Spot Nearly Perfect Supernova Remnant of Unknown Size and Distance
Astronomers have spotted a nearly perfect spherical supernova remnant named Telios on the Milky Way’s outskirts. With its low brightness and unknown distance, Telios defies standard models of cosmic remnants and may signal a rare Type Ia supernova. Its symmetry makes it one of the most intriguing galactic remnants ever recorded.

Astronomers Discover Teleios, A Supernova Remnant with Perfect Symmetry
A newly discovered supernova remnant named “Teleios,” meaning “perfect” in Greek, is astonishing scientists with its rare circular symmetry. Detected using data from ASKAP’s Evolutionary Map of the Universe, Teleios (G305.4–2.2) could be located 7,170 or 25,100 light years away. With a steep spectral index and low surface brightness, it...

Hubble Captures Stunning Image of Peculiar Spiral Galaxy Arp 184 in Camelopardalis
Arp 184, also known as NGC 1961, is a stunning yet asymmetrical spiral galaxy captured by NASA/ESA’s Hubble Space Telescope. Located about 190 million light-years away in the Camelopardalis constellation, it features a single, starry spiral arm and a rich history of supernovae. Included in Halton Arp’s Atlas of Peculiar Galaxies, Arp 184 stands...

Signs Of A Supermassive Black Hole Hiding In Nearby Spiral Galaxy
Webb witnessed a highly ionised gas whose level of energy was too high to come from something like supernovae, making scientists believe the presence of a supermassive black hole.

First Future Type 1a Supernova Detected: White Dwarf Pair to Collide in 23 Billion Years
Astronomers have discovered a pair of white dwarf stars located about 150 light-years from Earth that are on course to collide and produce a Type 1a supernova in approximately 23 billion years. This is the first such system identified near our region of the galaxy. With a combined mass of 1.56 solar masses, the stars are slowly spiralling toward ea...

T Corona Borealis May Erupt Soon: Rare Nova Could Be Visible to Naked Eye
T Corona Borealis, a binary star system in the Northern Crown constellation, is showing signs of an imminent nova eruption. The white dwarf star, which pulls material from its red giant companion, last erupted in 1946. Astronomers have detected patterns similar to previous eruptions, leading to predictions of a possible outburst within the next two...

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...
