Astronomers Identify First Known Green Star, a Rare White Dwarf ‘Zombie’ Near Halloween

Astronomers have reported the first known green star, a bizarre white dwarf system whose unusual color appears to come from a companion star and the physics of stellar remnants rather than from a single, naturally green sun. The finding adds a striking new data point to the study of white dwarfs, the dense cores left behind after stars exhaust their fuel, and may help refine how scientists classify the final stages of stellar evolution.

Astronomers Spot Record-Distant Blazar, a Beacon From the Early Universe

Astronomers have identified the most distant supermassive black hole-powered blazar ever observed, a discovery that pushes the frontier of high-energy astrophysics deeper into cosmic history. The object, known as Blazar OP 313, offers a rare view of a jet-emitting black hole active when the universe was still in its formative stages.

Radio Astronomers Push Back on Starlink’s Gen 3 as Satellite Crowding Debate Intensifies

Starlink’s proposed Gen 3 satellite system is drawing renewed opposition from radio astronomers, who warn that a larger, more powerful constellation could intensify interference with sensitive observations of the universe. The dispute underscores a growing policy tension between rapid commercial expansion in low Earth orbit and the scientific community’s need to preserve quiet radio spectrum for research.

Astronomers Find Signs of Two Feeding Black Holes Separated by Just 175 Parsecs in the Early Universe

New evidence suggests that two actively feeding black holes may be lurking only 175 parsecs apart in a distant early-universe system, a separation that would make them extraordinarily close on cosmic scales. The finding, reported in Phys.org coverage of recent research, could help explain how supermassive black holes grew so rapidly after the Big Bang and how early galaxies assembled their mass.

Astronomers Detect Signs of a Planet Born After a Star’s Death

Astronomers have reported evidence suggesting that a planet may have formed from the debris of a dying star, a rare scenario that would make it a so-called second-generation world. The finding, if confirmed, could reshape understanding of how planetary systems evolve after stellar death and how material recycled from old stars can seed new planets.

Astronomers Detect Variable Water Clouds Beyond the Solar System for the First Time

Astronomers have reported the first detection of changing water clouds outside the solar system, identifying patchy and variable cloud structures on a cold brown dwarf roughly 20 light-years from Earth. The finding sharpens understanding of atmospheric dynamics on objects that sit between planets and stars, and it may help scientists refine models used to interpret distant worlds, including those relevant to climate and habitability research.

Astronomers Release High-Definition View of a 12th-Century Supernova Remnant

Astronomers have unveiled a sharper view of a supernova remnant first seen by humans nearly 850 years ago, revealing intricate gas knots and pearl-like structures around the debris field. The new imagery of Pa 30 offers fresh evidence about how rare stellar explosions evolve and how their remnants can illuminate the physics of extreme cosmic events.
