The man keeps the rock for years, hoping it's gold.  It turns out to be much more valuable

The man keeps the rock for years, hoping it’s gold. It turns out to be much more valuable

In 2015, David Hole was prospecting in Maryborough Regional Park near Melbourne, Australia. Armed with a metal detector, he discovered something out of the ordinary – a very heavy reddish rock lying in yellow clay. He took it home and tried everything to crack it open, sure there was a nugget of gold inside the …

A lab-grown black hole could prove Stephen Hawking’s toughest theory right

Scientists have created a lab-grown black hole analog to test one of Stephen Hawking’s most famous theories – and it’s behaving exactly as he predicted. The experiment, created using a string of single-file atoms to simulate a black hole’s event horizon, added further evidence to Hawking’s theory that black holes should emit a faint glow …

Something Infernal Might Be Lurking Beneath One of Jupiter's Moons

Something Infernal Might Be Lurking Beneath One of Jupiter’s Moons

There are over 200 moons in the solar system, but none quite like Io, the third largest of Jupiter’s 80 moons. Io is really, really volcanic. In fact, it’s dotted with so many hundreds of mighty active volcanoes that there must be something unusual beneath its crust. According to a new study published in the …

We Now Know Why Black Hole Jets Produce High-Energy Radiation

Enlarge / The jets of material ejected around black holes can be enormous. Active galactic nuclei, powered by the supermassive black holes they contain, are the brightest objects in the Universe. The light comes from jets of matter projected at a speed close to light by the environment around the black hole. In most cases, …
