Astronomers Capture First-Ever Image of a Dead Star That Exploded Twice in Rare Supernova Event
- Saturday July 5, 2025
- Written by Gadgets 360 Staff
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 Spot Nearly Perfect Supernova Remnant of Unknown Size and Distance
- Wednesday May 28, 2025
- Written by Gadgets 360 Staff
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
- Saturday May 17, 2025
- Written by Gadgets 360 Staff
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...

Supernova Remnants Found in Oceanic Samples, Scientists Look to Moon
- Wednesday March 26, 2025
- Written by Gadgets 360 Staff
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...

Zombie Star’s Mysterious Spiky Filaments Baffle Astronomers in New Discovery
- Thursday January 23, 2025
- Written by Gadgets 360 Staff
A zombie star remnant, Pa 30, located 6,500 light-years from Earth, is surrounded by spiky filaments that have baffled astronomers. These filaments, observed for centuries, continue to puzzle scientists, as their formation and long-term stability remain unclear. The star's explosion in 1181 was initially noted by skywatchers, but its remnant struct...

Supernova Remnant G278.94+1.35 is Closer to Earth, Claims New Study
- Friday January 10, 2025
- Written by Gadgets 360 Staff
Astronomers discovered that the supernova remnant G278.94+1.35 is located just 3,300 light years away, much closer than previously believed. Initially thought to span over 500 light years, it is now estimated to measure around 189 by 182 light years. Named "Diprotodon" after Australia’s extinct giant marsupial, this structure remains in an expand...
