Is It Natural? Interstellar Object 3I/ATLAS Shows an Odd Protrusion on Its Sunward Path
Interstellar visitors aren’t just a sci‑fi dream — they’re real. In a surprising turn of observation, astronomers tracking the interstellar object 3I/ATLAS have noted a strange protrusion along its sunward side as it speeds toward the inner solar system. This feature, often called an anti-tail when it points toward the Sun, has sparked lively debate…

Water Formation on Planets Could Expand Habitable Worlds
Water forming as planets coalesce For decades, scientists have wondered where a planet’s water comes from. While comets and asteroids have long been thought to deliver a crucial amount of water to young worlds, new research points to a complementary process: water can also be forged during the very act of planetary formation. If many…

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…

Could Planets Forge Water During Formation and Boost Habitability?
New Insight: Water May Be Forged During Planet Formation For a long time, scientists have pondered how Earth acquired its precious water. While comets and asteroids have often been blamed as icy couriers delivering water to young planets, emerging research suggests a complementary mechanism: planets might synthesize water themselves as they come into being. If…

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…
