Webb just clocked nearly 9,000 young star clusters and found the biggest ones break from their birth clouds in 5 million years, a timing clue that could reshape how astronomers model galaxies growing up

The Hubble Deep Field began as a gamble on a tiny patch of sky that had been chosen because it looked almost empty, and it ended by revealing nearly 3,000 galaxies hiding in what seemed like nothing.

Titan’s atmosphere is thicker than Earth’s, its rivers and lakes are made of methane and ethane, and NASA is sending a nuclear-powered drone there because on Saturn’s largest moon, flying may be easier than driving.

Enceladus is a tiny moon of Saturn that sprays water vapor and ice grains into space from an ocean hidden beneath its icy crust — meaning a spacecraft can sample material from an alien sea without ever landing.

In 1908, something exploded in the sky over Siberia with hundreds of times the energy of the Hiroshima bomb, flattening more than 2,000 square kilometres of forest. When scientists finally reached the site years later, they found no crater at all

The modern 8-hour workday is usually traced to Robert Owen, a Welsh industrialist and social reformer, who in 1817 popularized the formula: ‘eight hours’ labour, eight hours’ recreation, eight hours’ rest.’ Does this split still make sense in 2026?

Anthropologist Marshall Sahlins called early hunter-gatherer societies “the original affluent society” — not because they had more than us, but because they wanted less than they had, and worked the minimum required to meet what they wanted

A slice of the static on an old untuned television was the afterglow of the Big Bang, which means millions of people spent decades staring at the oldest light in the universe without knowing it.

The Voyager Golden Record carries a small sample of uranium on its cover, placed there so that whoever finds it can measure the decay and work out how long it has been drifting — a built-in clock for a message engineered to last around a billion years.

Voyager 2 photographed Neptune in light so dim that some exposures lasted seconds or even minutes, while the spacecraft was racing past the planet. To stop the images smearing, engineers programmed the spacecraft itself to compensate for the motion, turning the whole probe into its own image-stabilisation system.
