Astronomers Discover Calvera, a Runaway Pulsar Racing Above the Milky Way
Astronomers have discovered Calvera, a pulsar speeding 6,500 light-years above the Milky Way’s disk. Formed from a supernova in a nearly empty region, Calvera challenges long-held ideas of star birth and death. Its discovery reveals that extreme stellar events can occur even in the galaxy’s sparse outer halo.

Hubble Discovers White Dwarf Merger Remnant with Unusual Carbon Signature
An international team of astronomers has discovered WD 0525+526, an unusual white dwarf about 128 light-years away, using NASA’s Hubble Space Telescope. Unlike typical white dwarfs, this star formed through a stellar merger and shows an unexpectedly high carbon content. With a mass of 1.2 Suns and a scorching surface temperature of 21,000 K, the ...

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...

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...

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.
