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...

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...

Five Dwarf Galaxies Found in a Rare Alignment, Challenges Current Cosmic Models
A rare alignment of five dwarf galaxies, positioned around 117 million light-years away, has been discovered by astronomers. This grouping, which challenges existing models of galaxy formation, shows active star formation despite their small sizes. The galaxies, labelled D1 to D5, exhibit unique characteristics, including shared rotational motion a...

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...

TRAPPIST-1b Could Have Carbon Dioxide-Rich Atmosphere, Study Reveals
A new study published in Nature Astronomy proposes that TRAPPIST-1b, the innermost planet in the TRAPPIST-1 system, might have a carbon dioxide-rich atmosphere. This discovery comes from new data showing a reflective haze in the planet's upper atmosphere. Scientists are also investigating the possibility of volcanic activity based on the planet’s...

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...

Hubble Space Telescope Captures Rare Edge-On View of a Spiral Galaxy Located Millions of Light-Years Away
NASA and ESA’s Hubble Space Telescope captured an edge-on view of spiral galaxy UGC 10043, located around 150 million light-years away. Displaying its prominent dust lanes and unique bulge, this galaxy image highlights regions of active star formation. Captured in 2000 and 2023, the composite image uses various light wavelengths to detail the str...

Hubble Telescope Reveals Milky Way Blowing Gas off LMC Galaxy in Close Encounter
NASA’s Hubble Space Telescope has captured an extraordinary phenomenon as the Milky Way galaxy exerts ram pressure on the Large Magellanic Cloud (LMC), stripping away most of its gas halo. The interaction, which occurs as LMC passes near the Milky Way, has led to the loss of significant mass from the dwarf galaxy. Despite this, LMC retains enough...
