Planets Forge Water During Formation Expands Habitability
Water Isn’t Just Delivered: It’s Also Forged For decades, scientists have pondered where Earth’s water came from and whether similar oceans could exist on distant worlds. A growing line of evidence now suggests that water may not be solely delivered to rocky planets after they form. Instead, the very process of planetary formation could forge…

Interstellar Comet 3I/ATLAS Shows Water Emission Far from the Sun, Hinting at Life-Building Molecules Crossing the Galaxy
Interstellar Guest 3I/ATLAS Delivers Surprising Water Signatures In a landmark discovery, the interstellar visitor 3I/ATLAS has shown measurable signs of water, challenging assumptions about how water and the ingredients of life might move through the galaxy. As the third known object to enter our solar system from another star, 3I/ATLAS is no longer just a…

Water’s Ultraviolet Fingerprint Detected in Interstellar Comet 3I/ATLAS
Interstellar Ice Reaches Our Solar System For millions of years, a fragment of ice and dust wandered between the stars. This summer, that cosmic traveler—named 3I/ATLAS—made a rare entry into our solar system, becoming only the third confirmed interstellar comet. Its journey has already begun to reshape our understanding of how planetary materials form and…

Ultraviolet fingerprint of water detected in interstellar comet 3I/ATLAS
Interstellar visitors and a long-awaited water signal For millions of years, a fragment of ice and dust drifted between the stars, a sealed bottle released into the cosmic ocean. This summer, that bottle washed ashore in our solar system as 3I/ATLAS, only the third known interstellar comet. In a landmark observation, Auburn University scientists used…

Reimagining Venus Clouds: Water-Rich Hydrates Rewrite a Planet’s Atmospheric Tale
New Look at an Old Mission Fifty years after NASA’s Pioneer Venus mission descended through Venus’ clouds, researchers have revisited the mission’s mass spectrometry data with modern techniques and a fresh hypothesis. The result: Venus’ cloud decks may be far more water-rich than previously believed, with water largely bound in hydrated minerals rather than existing…

Liquid Water on Ryugu Reveals a Billion-Year-Old Secret
Liquid Water on Ryugu: A Hidden Water Trail Across Time A recent study of tiny rock fragments returned from the asteroid Ryugu by JAXA’s Hayabusa2 spacecraft has upended assumptions about when and how water could move through asteroids. The research, involving scientists from the University of Tokyo among others, shows that liquid water once traversed…

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…

Evidence of Flowing Water on Ryugu’s Parent Asteroid
Introduction: A Surprising Discovery Recent research has unveiled an astonishing finding: liquid water flowed across the surface of the asteroid that birthed the near-Earth object (NEO) Ryugu. This revelation comes as a genuine surprise to scientists, as it challenges previous assumptions about the timeline of water presence in our solar system. The study indicates that…
