Scientists Solve Mystery Of Puzzling Radio Pulses From Space
Cosmic radio pulses repeating every few minutes or hours, known as long-period transients, have puzzled astronomers since their discovery in 2022. Our new study, published in Nature Astronomy today, might finally add some clarity.

James Webb Captures Stunning Infrared Image of the Helix Nebula Eye of God
The James Webb Space Telescope has captured a detailed infrared image of the Helix Nebula, also known as the “Eye of God.” The glowing ring of gas around a white dwarf star reveals filaments and knots formed as stellar winds collide with older material, offering insight into the fate of Sun-like stars.

White Dwarf Gobbles Up Nitrogen-Rich Ices of Pluto-Like World
Astronomers have observed a white dwarf, a highly compact stellar ember, that appears to have gobbled up an icy world akin to dwarf planet Pluto, a finding with implications regarding the likelihood of habitable planets beyond our solar system

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 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...

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...

Alien Life May Survive on Planets Orbiting White Dwarfs, Study Finds
New research explores the possibility of alien life on planets orbiting white dwarfs. While these stellar remnants cool over time, their shrinking habitable zones may still allow biological processes like photosynthesis and UV-driven abiogenesis to occur. A model assessing a planet's energy reception over seven billion years indicates that life-sus...

New Polar Cataclysmic Variable Identified by Astronomers: What You Need to Know
Astronomers have detected ZTF J0112+5827, a newly identified polar cataclysmic variable. This binary system, composed of a white dwarf and a low-mass donor star, features an 80.9-minute orbital period and a strong magnetic field of 38.7 MG. It lacks an accretion disk, with emissions mainly from its accretion stream and magnetic field lines. The sys...

X-ray Signal from Helix Nebula Suggests Planet Was Destroyed by White Dwarf
Astronomers have traced decades-old X-ray emissions from the Helix Nebula to a white dwarf possibly consuming planetary debris. Reports suggest a Jupiter-like planet may have been torn apart by the star’s intense gravitational forces. Data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton indicate that remnants of the destroyed plane...

Strange Fast Radio Bursts Emerge from an Ancient Dead Galaxy, Baffling Scientists
Scientists have detected mysterious fast radio bursts (FRBs) from the outskirts of an 11 billion-year-old dead galaxy. This discovery challenges the belief that FRBs primarily originate from young, star-forming galaxies. Researchers suspect the bursts may result from colliding stars or a collapsing white dwarf. The Canadian Hydrogen Intensity Mappi...

Unprecedented Cosmic Explosion Discovered: Could This Be The Greatest Space Mystery Ever?
A newly detected cosmic explosion, EP240408a, could be the result of a white dwarf's death, creating a high-speed jet. It offers new insights into astrophysics.

Astronomers Observe Black Hole Reactivate, Emitting Jets of Plasma
A supermassive black hole at the center of galaxy 1ES 1927+654 has been observed reactivating after a quiet period. Jets of hot gas were released from both sides of the black hole, surprising astronomers. Researchers speculate that a white dwarf star in close orbit may be interacting with the black hole, providing key insights into cosmic behavior....

NASA’s Hubble Observes Rare Blue Lurker Star with Unusual Evolution in M67 Cluster
NASA’s Hubble Space Telescope has identified a rare stellar phenomenon called the “blue lurker” in the M67 star cluster. Located 2,800 light-years away, this star is part of a triple-star system and has an unusual evolutionary history. The blue lurker’s accelerated spin, taking just four days, contrasts with the typical rotation of Sun-like...

Astronomers Discover Unusual X-Ray Oscillations From a Black Hole 100 Million Light-Years Away
A supermassive black hole 100 million light-years away is showing an unprecedented increase in X-ray oscillations, starting from 18-minute intervals and accelerating to 7 minutes in just two years. Astronomers believe a white dwarf, orbiting perilously close to the event horizon, is causing these flashes. The findings offer a glimpse into black hol...
