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…

White Dwarf Binary: First Look at the Inner Region
A New View into a Dead-Star Dance About 200 light-years from Earth, a binary pairing hides in plain sight: a white dwarf—the dense remnant of a once-sunlike star—and its larger stellar companion. Recent observations provide the first close look at the innermost region where their gravitational and magnetic forces shape a cosmic waltz of matter.…

Scientists See the Innermost Region of a White Dwarf Binary for the First Time
Unveiling a Rare Cosmic Dance About 200 light-years from Earth, a binary star system is offering scientists a rare, close look at the innermost region where a white dwarf and a companion star engage in a complex gravitational and magnetic ballet. The dead star, a dense white dwarf, siphons material from its larger partner, forming…

First Glimpse Inside a White Dwarf Binary’s Innermost Region
Unveiling a Cosmic Dance: The Innermost Region of a White Dwarf Binary About 200 light-years from Earth, a dramatic celestial pairing is offering scientists a rare glimpse into the extreme physics at the heart of a white dwarf binary. In this system, a dense, magnetized white dwarf siphons material from a larger companion star, creating…

Astronomers Spot a White Dwarf That’s Still Consuming Its Planets
Unexpected Activity Around a Dying Star In a surprising twist to our understanding of stellar evolution, astronomers have observed a white dwarf actively consuming material that once constituted a planetary system. While white dwarfs are the dense, fading cores left behind when stars like our Sun exhaust their nuclear fuel, this discovery shows that planetary…

White Dwarf Consuming Planets: New Evidence Emerges
New Evidence That White Dwarfs Eat Planets Astronomers have found compelling signs that white dwarfs—the dense, remnant cores left after stars like the Sun exhaust their fuel—can continue to interact with their own planetary systems. In a growing body of observations, these stellar remnants show atmospheric signatures and surrounding debris consistent with the ongoing accretion…

Astronomers Spot a White Dwarf That’s Still Consuming its Planets
Unexpected Activity Around a Dying Star Astronomers have identified a white dwarf that appears to be actively consuming remnants of its former planetary system. This surprising discovery challenges long-held assumptions about how planetary bodies survive, break apart, or are torn apart after their star ends its life on the main sequence. By studying the chemical…

Astronomers Unveil ASKAP J1832-0911: A 44-Minute Cosmic Beacon Defying Stellar Models
Discovery of the enigmatic radio source ASKAP J1832-0911 An international team of astronomers has identified an extraordinary space object that emits radio waves and X-ray bursts toward Earth with clockwork precision. Designated ASKAP J1832-0911, the source sits roughly 16,000 light-years away and produces radio signals every 44 minutes, each lasting exactly two minutes. This unusual…

White Dwarf Engulfs Pluto-Like Icy World, Exoplanet Clues
Discovery: A White Dwarf and an Icy Pluto-Like World Astronomers using the Hubble Space Telescope have identified a white dwarf in the Milky Way that carries chemical traces of having swallowed an icy body similar to Pluto. The star sits about 255 light-years from Earth and weighs roughly 0.57 solar masses. White dwarfs are the…

White Dwarf Swallows Pluto-Like Icy World: Implications for Habitable Planets
New finding from Hubble reveals a white dwarf feasting on an icy Pluto-like world Astronomers using the Hubble Space Telescope have identified a striking example of a white dwarf—one of the universe’s most compact stellar remnants—appearing to have consumed an icy, Pluto-like body. The star resides in the Milky Way, roughly 255 light-years from Earth,…
