The Loudest Black-Hole Collision Yet Let Astronomers Touch the Event Horizon Itself
GW250114, the loudest black-hole merger ever recorded and ~3x louder than 2015's GW150914, carries the first gravitational-wave signature tied to a remnant's event horizon rather than its light ring — opening a channel to measure frame-dragging and horizon surface gravity.

Not Ice Giants After All: A New Model Recasts Uranus and Neptune as Magma-Ocean Worlds
A June 2026 preprint argues Uranus and Neptune aren't water-ice worlds but supercritical, hydrogen-rich magma oceans under H2 envelopes — a model that, with just three parameters per planet, reproduces nearly everything we measure.

A Galaxy Shaped Like a Bow and Arrow Is Plowing a 1.8-Million-Light-Year Shockwave Through Space
Citizen scientists working with India's RAD@home collaboratory and LOFAR images found RAD-BAARG, a radio galaxy falling supersonically into a cluster and carving a glowing bow shock about 1.8 million light-years across.

Your July 2026 Night Sky: A Daytime-Bright Venus, the Buck Moon, and a Fireball-Rich Meteor Finale
July 2026 hands naked-eye observers a brilliant magnitude -4 Venus near Regulus, a razor-thin 0.11-degree Mars-Uranus pairing before dawn on July 4, the Full Buck Moon on July 29, and twin meteor showers — including fireball-prone Alpha Capricornids — closing the month.

NASA's Moon Base Rovers Get Real: Astrolab and Lunar Outpost Race Toward a 2027 Delivery
NASA wants two commercially built crewed rovers parked near the lunar South Pole by November 2027, ahead of the Artemis 4 landing in early 2028. Here's how Astrolab's CLV-1 and Lunar Outpost's Pegasus aim to survive 150 days of dark at -400°F and still drive 400 km.

Hubble Catches a Tiny Galaxy Burning Off the Cosmic Fog, 1.4 Billion Years After the Big Bang
Astronomers used Hubble to catch ionizing UV light escaping a small, furiously star-forming galaxy in the reionization epoch — the first such detection, and direct evidence for how the early universe became transparent.
