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....

Webb Telescope Tracks Formation and Expansion of Carbon-Rich Dust Shells in Star System
As per the latest report by NASA, the system consists of two stars in an elongated orbit. When these stars come closest, their stellar winds collide, compressing material and forming carbon-rich dust. As reported in an official press release by NASA, Emma Lieb, a doctoral student at the University of Denver and the study's lead author, noted that t...

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...

White Dwarf’s Unexplainable Rapid Spin Finally Decoded by Scientists
The white dwarf star RX J0648.0–4418, 1,700 light-years away, spins at a rapid pace of 13 seconds per rotation. Part of a binary system with a helium-burning hot subdwarf star, it continues to shrink while accreting material. This rare and short-lived system provides a unique view into stellar evolution. Approaching the Chandrasekhar limit, RX J0...

Astronomers Spot New Cosmic Explosions 100 Times Brighter Than the Sun
Astronomers have discovered a new class of cosmic explosions, known as 'millinovas,' which are 100 times brighter than the Sun. These events, first identified in 2023, were observed in the Large and Small Magellanic Clouds, two satellite galaxies of the Milky Way. The millinovas are thought to occur when white dwarfs feed off a companion star, prod...

T Coronae Borealis' Nova Outburst May Happen Soon, Experts Suggest
Astronomers are closely monitoring T Coronae Borealis, a binary star system in the Corona Borealis constellation, for its next nova eruption. The event, expected within months, could light up the night sky as the white dwarf gathers material from its red giant companion, triggering a nuclear explosion. Advanced telescopes like NASA’s Fermi are ga...

Supernova SN 1181 Reveals Rare “Zombie Star” in Pa 30 Nebula
A supernova recorded in 1181, known as SN 1181, has been linked to the Pa 30 nebula, revealing a rare “zombie star.” Advanced 3D imaging from the Keck Observatory has shown unusual filaments expanding from this star, marking it as a unique case in supernova studies. This zombie star survived a thermonuclear explosion on a white dwarf, challengi...

Unraveling the Story of Pa 30: A Supernova's Remarkable Legacy
Pa 30 is a fascinating nebula that emerged from a supernova observed in 1181. At its center lies a remarkable white dwarf, often called a "zombie star," which continues to emit extraordinary heat and light. Recent studies utilizing advanced mapping techniques have unveiled new details about the nebula's unique shape and rapid expansion, offering in...

Exoplanet Orbiting a White Dwarf Star Gives Researchers Hope That Earth Might Escape Its Eventual Death
A planetary system anchored by a white dwarf star, located approximately 4,000 light-years away, provides astronomers with insights into what could happen to our Sun and Earth in about 8 billion years. This scenario unfolds if the Earth survives the Sun's transformation into a red giant, expected to occur in 5 to 6 billion years.

NASA Citizen Scientists Discover Mysterious Object Moving out of Milky Way at an Extremely High Speed
On August 15, 2024, NASA’s Backyard Worlds: Planet 9 project, featuring the contributions of dedicated citizen scientists, made a groundbreaking discovery: an object moving at an astonishing speed of 1 million miles per hour, which will soon escape the gravitational pull of the Milky Way. This hypervelocity object, catalogued as CWISE J124909.08+...

"Once-In-A-Lifetime" Cosmic Explosion Will Be Visible From Earth, Says NASA
The "Blaze Star," which is a binary system in the Northern Crown about 3,000 light years from Earth, is comprised of a white dwarf, an Earth-sized remnant of a dead star with a mass comparable to the sun.

What Will Happen To Our Solar System When Sun Dies? Study Explains
The study mentions the exoplanets orbiting two different white dwarf stars named WD 1202-232 and WD 2105-82 at distances of 34 and 53 light-years from Earth, respectively. They are believed to be between 1 and 7 times the mass of Jupiter.
