Black Hole

This stunning NOIRLab Image of the Week captures the NSF–DOE Vera C. Rubin Observatory’s first breathtaking look at the third confirmed interstellar visitor to our Solar System — snapped on December 19, 2025, at its closest approach to Earth. Blazing through at a mind-melting 153,000 mph (240,000 km/h), 3I/ATLAS screamed past us like a cosmic bullet from another star system. Yet Rubin’s gigantic mirror and ultra-sensitive camera nailed it in a single 30-second exposure: a delicate, glowing coma and faint tail shimmering against a razor-sharp backdrop of distant stars and galaxies. Pure observatory magic. Right now the comet is outbound, racing toward Saturn’s orbit while ducking into the Sun’s glare — already saying its goodbyes. Every interstellar traveler like 3I/ATLAS is a priceless postcard from another stellar neighborhood. With Rubin just getting started, we’re about to meet dozens more. Get ready for the ultimate cosmic comparison tour: how does our Solar System stack up against the rest of the galaxy?

Absolutely worth the visit. 10/10 would recommend to any passing star system.
