Rings in Formation: Astronomers Observe Protoplanetary Rings Sprouting Around the Icy Body Chiron
Rings in Real Time Around a Small World In a striking glimpse of planetary dynamics on a much smaller stage than Saturn’s vast system, astronomers have observed a ring system forming around Chiron, a small icy body that orbits the Sun between Saturn and Uranus. This discovery marks the first time scientists have captured rings…

ESA’s Mars Watch Captures Interstellar Visitor 3I/ATLAS in Glimpse of the Unknown
Rare Interstellar Visitor Reaches the Mars Scene On October 3, a rare interstellar visitor, comet 3I/ATLAS, passed by Mars at a distance of about 30 million kilometers. While comets are common in our solar neighborhood, 3I/ATLAS is extraordinary because it originated outside the Sun’s gravity, offering a priceless glimpse into material from another star system.…

Hidden Planet Y: Evidence Mounts for a World Beyond Neptune
What hints point to a hidden World Beyond Neptune For decades, scientists have speculated about undiscovered worlds lurking in the outer solar system. The latest clues come from precise measurements of distant icy bodies that orbit well beyond Neptune. A team led by Amir Siraj analyzed roughly 50 Kuiper Belt objects—frozen remnants of the solar…

Hidden Planet Y: Astronomers Find Clues in the Kuiper Belt
New Clues Point to a Hidden World Astronomers are gathering evidence that could point to a hidden planet in our solar system. In a study focusing on icy bodies far beyond Neptune, researchers found unusual tilts in their orbits that standard models cannot explain. The collective tilt pattern has led to renewed interest in the…

Astronomers Point to Hidden Planet Y Beyond Neptune
Unseen Influences in the Outer Solar System For decades, scientists have wondered whether the outer solar system harbors a hidden planet. The latest clue comes from a careful survey of distant icy bodies beyond Neptune. Researchers analyzed roughly 50 Kuiper Belt objects (KBOs) and found orbital tilts that don’t align with current models of planetary…

Replicating Probes in the Solar System: Techno-Signatures and Lunar Manufacturing
Introduction: A neglected frontier in SETI For decades, SETI has focused on signals from distant stars, yet a more terrestrial angle deserves attention: solar system techno-signatures. As humanity inches toward commercial space activity and a potential widening of planetary exploration, clues of extraterrestrial technology may lie not in interstellar beacons but in the way resources…
