Full Moon to Wash Out Peak of Delta Aquariid–Alpha Capricornid Double Meteor Shower
A nearly full moon will drown out most of the Southern Delta Aquariids' July 28-29 peak, but the slower, brighter Alpha Capricornid fireballs that follow on July 30-31 should still cut through the glare.

Starship Flight 13 Deploys First Operational Starlinks, but Booster Splashdown Gets Rough
SpaceX's Starship Flight 13 delivered 20 production Starlink satellites and an in-space Raptor relight, but Super Heavy limped to a hard splashdown on just five of 13 engines.

The Sun Fired Two Eruptions at Once, and One Just Missed Us
A central-meridian filament blast and a far-side prominence erupted in near-perfect sync on July 28, while AR4494 kept flaring and a G1 storm carried over from an incoming CME due July 30.

A Black Hole Wandered 30,000 Light-Years From Home — Then It Ate a Star
NASA's Swift Observatory and a UNC-Chapel Hill team caught a roughly million-solar-mass black hole shredding a star far outside its galaxy's core — the farthest such offset ever seen, and evidence that black holes can go wandering after galactic mergers.

Fourteen Years, Twenty Miles: Curiosity's Wheels Show Their Age in New Close-Up
A new MAHLI close-up from Sol 4963 shows Curiosity's aluminum wheels riddled with cracks and holes after nearly 14 years and 20+ miles of driving across Gale Crater — and NASA says that's still within spec.

A House-Sized Asteroid Just Passed Closer to Earth Than the Moon
Newly discovered asteroid 2026 OD3 buzzed past Earth at 0.6 lunar distances on July 25, one of three close flybys this week that underscore how many small asteroids go undetected until days before arrival.

LIGO's Latest Catalog Sorts Black-Hole Mergers Into Four Distinct Families
A new analysis of LIGO-Virgo-KAGRA's fifth transient catalog finds statistical evidence for four separate black-hole merger populations — including a rare group of black holes built from earlier mergers.

Black Holes With Past Lives: GWTC-4 Reveals a Hidden Population of Second-Generation Mergers
Mining the LIGO-Virgo-KAGRA GWTC-4 catalog, an MIT-led team finds that roughly 14% of merging black holes are themselves products of earlier collisions, with a spin-driven transition near 46 solar masses.

The 'Metallic Waves' of Kaiser Crater Are an Optical Trick — Here's the Geology Underneath
Mars Express imaged a shimmering, metallic-looking dune field on the floor of Kaiser Crater. It's an illusion: bright winter hoarfrost draped over 100-meter dark basaltic dunes, with clays and gullies hinting at a wetter past.
