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,…

White Dwarf Feasts on Pluto-like World, Hinting at Icy Exoplanets
A White Dwarf and an Ice-World Snack Astronomers using the Hubble Space Telescope have identified a white dwarf star—an ultra-dense, compact stellar remnant—that appears to have consumed an icy body resembling Pluto. The finding, published in Monthly Notices of the Royal Astronomical Society, provides a striking clue about the kinds of frozen material that exist…
