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…

Early Hydrogen-Iron Reactions Key to Planetary Habitability
Unraveling the Role of Hydrogen-Iron Chemistry in Planetary Habitability How water forms on distant worlds is one of the most pressing questions in the search for life beyond Earth. A recent international study, published in Nature, sheds new light on the early hydrogen-iron reactions that could drive water formation on exoplanets. By examining how simple…

Early Hydrogen-Iron Reactions and the Water Puzzle on Exoplanets
Understanding the Water Puzzle on Distant Worlds How water forms on exoplanets is a central question in the search for life beyond Earth. A new study published in Nature tackles this by examining early chemical processes that could seed oceans long before planets reach maturity. By focusing on the interactions between hydrogen and iron in…

Early Hydrogen-Iron Reactions Could Shape Exoplanet Habitability
Overview: Water Formation on Exoplanets and Habitability Water is a cornerstone of planetary habitability, influencing atmospheres, geology, and potential biosignatures. A recent international study, published in a leading science journal, investigates how early hydrogen–iron reactions could drive the formation of water on exoplanets. By examining the chemistry occurring during the earliest stages of planet formation,…

How Planets Get Wet: Water Formation During Planet Birth
Introduction: Water in the Birth of Planets When we imagine how planets acquire their oceans, the scene often jumps from cometary delivery and late-stage accretion to steady rain on a settled world. But new research is shifting that narrative by proposing a more intrinsic origin for water: it forms during the very birth of a…

How Planets Get Wet: Water Creation During Planet Formation
Introduction: A Wet Start for Planets For years, scientists have wondered how rocky planets acquire their water—whether it is delivered after formation by comets and asteroids, or whether water can emerge in the early molten stages of planet building. Recent work published in Nature by researchers affiliated with Carnegie and other institutions suggests a compelling…

How Planets Get Wet: Water Formation During Planetary Birth
Introduction: The Curious Question of Wet Planets From our own world to distant exoplanets, the presence of liquid water is a defining factor for habitability. But how do planets acquire their water in the first place? Recent research published in Nature by Carnegie scientists suggests a compelling mechanism: water can be generated during the planet’s…

GO-LoW: A New Frontier Revealing the Low-Frequency Radio Cosmos
Unveiling the Hidden Sky: GO-LoW’s Mission For centuries, humanity has peered at the stars, expanding our understanding of the cosmos with naked-eye observations and increasingly sophisticated telescopes. Yet a sweeping portion of the electromagnetic spectrum—the low-frequency radio sky—has remained largely unseen. Now, a NASA-funded concept study aims to change that with the Great Observatory for…
