More than 6,000 exoplanets confirmed in the Milky Way, including rocky worlds
1+ hour, 22+ min ago (290+ words) More than 6,000 exoplanets have been confirmed in the Milky Way, including terrestrial worlds that may be composed mainly of rock and metal. The NASA Exoplanet Archive listed 6,366 confirmed planets as of September 11, 2026, along with thousands of additional candidates awaiting verification....

A Cosmic Catastrophe May Have Turned Neptune’s Ancient Moons Inside Out
12+ hour, 51+ min ago (962+ words) In 1989, Voyager 2 discovered six previously unknown moons around Neptune. Five of them are tiny satellites that travel just beyond the planet’s main rings. Their small size and great distance from Earth have made them especially difficult to study in detail....
Planets larger than Earth but smaller than Neptune are extraordinarily common around other stars, yet our solar system has none. New solar-evolution modelling offers a dramatic possibility: the young Sun may have swallowed a rocky planet five to ten times Earth’s mass, leaving chemical and seismic fingerprints that could still be hidden inside it today.
16+ hour, 3+ min ago (1212+ words) Solar-evolution models favour engulfment of a compact world near 5.6 Earth masses, but the result is an indirect fit to helioseismic and chemical constraints rather than a detected lost planet....
Is This the First Exomoon
2+ day, 15+ hour ago (1676+ words) For decades, astronomers have been looking for moons beyond our Solar System. Several exomoon candidates have been proposed, but none has become an unambiguous, confirmed example. In a recent SETI Live conversation, host Dr. Franck Marchis spoke with Universidad Diego…...
Scientists Forced Water Into a Bizarre New State of Matter That May Explain Uranus and Neptune’s Strange Mgnetic Fields
14+ hour, 18+ min ago (575+ words) What happens to water when the usual rules no longer seem to apply? Scientists have recreated extraordinary conditions in the lab, uncovering a state of matter that could be hiding deep inside distant planets. Scientists have created a bizarre type…...
Meteorite Grains Preserve Evidence of a Magnetic Field in the Infant Solar System — Curiosmos
22+ hour, 3+ min ago (251+ words) Tiny minerals inside one of the most pristine meteorites ever found still carry a record of magnetism from the solar system’s first 200,000 years. Tiny mineral grains inside an Antarctic meteorite may preserve the oldest evidence yet of a magnetic field…...
