Vampire Star Unveiled: IXPE Reveals Feeding in a Dead White Dwarf System
Scientists Catch the First Glimpse of a ‘Vampire Star’ Feeding on Its Victim In a landmark discovery, researchers using NASA’s Imaging X-ray Polarimetry Explorer (IXPE) have captured the first detailed view of the inner region where a dying white dwarf siphons material from a close stellar companion. This “vampire star” scenario, where a compact remnant…

Scientists unveil first look at a ‘vampire star’ feeding on its victim
Introduction: A cosmic vampire’s feast under X-ray eyes Astronomers have captured the first detailed view of a so-called “vampire star” system, where a dying white dwarf is siphoning material from a nearby companion. Using NASA’s Imaging X-ray Polarimetry Explorer (IXPE), researchers peered into the enigmatic inner region around the dead star, gaining fresh insights into…

Oxygen Detected in Early Galaxies by Menelaos Raptis
Groundbreaking Discovery in the Early Universe A Greek physics student, Menelaos Raptis, studying at Franklin & Marshall College, has announced a breakthrough in our understanding of the early universe. By scrutinizing light from galaxies that formed roughly 12 billion years ago, Raptis and his collaborators have detected oxygen in the interstellar medium of two distant…

Record-Breaking Collision of Forbidden Black Holes: New Explanation Emerges
New Insights into the Universe’s Most Massive Merger In a landmark development, astronomers have traced the origins of the most massive black hole merger ever observed, offering a plausible pathway for the formation of two almost unfathomably large black holes. For years, researchers grappled with the idea of “forbidden” or “impossible” black holes — objects…

How Record-Breaking Black Hole Collision Could Redefine ‘Forbidden’ Giants
Introduction: A Collision That Defied Expectations In a discovery that challenges long-held beliefs about black holes, scientists have traced the origins of the most massive black hole merger yet observed. The collision involved two black holes whose sizes were once considered nearly impossible within standard models. This breakthrough not only identifies how such giants could…

Huge red giant star has newfound companion – and it may be a bad neighbor
A new companion to a looming red giant Astronomers have announced a surprising discovery: a nearby red giant star, already in the late stages of its life, now appears to have a closely orbiting stellar companion. The presence of this companion could dramatically alter the red giant’s behavior, affecting how it loses mass, pulsates, and…

Huge Red Giant Star Has New Companion: Could It Be a Bad Neighbor for Earth?
A New Twist in the Life of a Red Giant Astronomers have identified a close stellar companion orbiting an aging red giant, a finding that could upend long-standing assumptions about how these massive stars evolve and how they influence their surroundings. While red giants are already among the most dramatic phases of a star’s life,…

Huge Red Giant Star Finds New Companion: A Potentially Bad Neighbor for Earth
Introduction: A surprising partnership in the cosmos Astronomers have identified a surprising pairing: a aging red giant star with a closely orbiting stellar companion. This discovery matters not just as a curiosity of stellar dynamics, but as a window into the complex processes that govern red giants as they shed mass, burn their nuclear fuel,…
