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.

Astronomers From China, Australia Jointly Discover Binary System Ejecting Common Envelope
A team of astronomers from the Yunnan Observatories (YAO) of the Chinese Academy of Sciences and the Australian National University have jointly discovered a binary system that is ejecting a common envelope. The scientists have managed to observe a common envelope evolution, which has long been thought to be a key step in binary star system formati...

Meet the 'Zombie Star', Residing in Spiral Galaxy NGC 1309, That Survived Supernova Blast
Astronomers have observed a star that not only survived a stellar explosion called a supernova, but emerged from it brighter than before the blast. This white dwarf is gravitationally locked in orbit with another star — a pairing called a binary system.

Scientists Believe 'Alien' Rock Hypatia May Reveal Details on Events That Lead to Supernova Explosions
Researchers are hopeful that an extraterrestrial stone found in the Egyptian desert could help shed some light on these spectacular events. The stone is named Hypatia. The experts have a hypothesis that the Hypatia stone originated with a star – a red giant star collapsed into a white dwarf star, which eventually “ate” the other star.

Researchers Explore Potential Star System in Milky Way Which Can Burst Into Supernova
A team of researchers have found that a quadruple star system – known as HD 74438 – could represent a new channel by which thermonuclear supernova explosions can occur in the universe. In their study published in the journal Nature Astronomy, they have shown that the gravitational effects of the outer binary system are changing the orbits of th...
