James Webb Telescope Finds Evidence Of Giant "Dinosaur" Stars From Early Universe
The research also suggests that these massive stars transformed directly into black holes at the end of their lives without undergoing a supernova explosion.

JWST Detects Oldest Supernova Ever Seen, Linked to GRB 250314A
Astronomers using the James Webb Space Telescope have detected the oldest supernova ever recorded, tied to gamma-ray burst GRB 250314A. Occurring when the universe was only 730 million years old, the explosion provides a rare glimpse into the first generations of stars and early galaxy growth, highlighting Webb’s unmatched ability to study the di...

Astronomers Capture First-Ever Early Snapshot of Supernova Shock Wave Using ESO’s VLT
Astronomers using ESO’s Very Large Telescope have captured a rare early look at supernova SN 2024ggi, just one day after its discovery. The blast shockwave appeared olive-shaped—not spherical—revealing surprising asymmetry in the explosion. Recorded with the FORS2 instrument, the data shows the shock-breakout phase in unprecedented detail. Th...

Supernova’s First Moments Show Olive-Shaped Blast in Groundbreaking Observations
Astronomers captured the first moments of a nearby supernova, revealing an asymmetric, olive-shaped blast. In massive stars, core collapse after fuel exhaustion creates a shock wave. Early observations of future supernova surveys will be able to sample diversity in stellar explosions as well as the properties of broad breaks due to asymmetric sho...

Is the Universe Slowing Down? Astronomers Detect Signs of Fading Dark Energy
Astronomers from Yonsei University and DESI data analyses indicate dark energy, long believed constant, may be weakening. Corrected supernova results hint that cosmic acceleration is slowing—a possible “cosmic slowdown.” If true, this could help resolve the Hubble tension and redefine how the universe’s expansion and ultimate fate are under...

Deep-Sea Beryllium-10 Hints at Supernova Debris Reaching Earth 10 Million Years Ago
A new study has uncovered deep-sea evidence suggesting Earth may have been struck by debris from a nearby exploding star 10 million years ago. Scientists found unusually high levels of Beryllium-10 in Pacific crusts, consistent with a supernova origin. The findings could transform understanding of cosmic influences on Earth’s history, though terr...

Dead Star's Supernova Explosion Could Be Visible From Earth During Daytime, Study Predicts
When the two stars eventually smash into each other, the supernova explosion would be visible from Earth, even during daytime.

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.

New NASA Image Shows Expanding Supernova Remnant Resembling "Human Hand"
A newly released NASA image reveals extraordinary details of a pulsar-driven nebula, shaped like a human hand reaching through space.

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...

"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...
