The smudge turned out to be a visitor from another star. Gennadiy Vladimirovich Borisov had just discovered the first comet ever confirmed to have come from beyond our solar system - and by the naming rules of the International Astronomical Union, it would carry his name across the sky and into the textbooks: 2I/Borisov.

Tombaugh, though, made his find on the professional astrograph of Lowell Observatory. Borisov did something arguably harde...

Its path through space was too steep, too fast, and too open to be bound by the Sun's gravity. It was passing through, not orbiting: a chunk of ice and dust flung f...

On 21 January 2023, he spotted a small asteroid, 2023 BU, just five days before it swept past Earth - closer than the ring of geostationary satellites, though sti...

"In 2016, only I discovered a comet," he has said. "In 2013, there were seven of us. Every year there are less and less. There are more and more huge telescopes. Amateurs will soon have nothing left." Vast...
