In September 1994, David Noble used ropes to enter a remote sandstone gorge in Wollemi National Park, northwest of Sydney.
Vera Rubin did not watch individual stars race around distant galaxies in real time.
NASA's Kepler mission did not detect 300 million temperate rocky planets. It observed a narrow field of stars, found the small fraction of planets whose orbits…
Elephants make deep rumbles that sit mostly below the range of human hearing. Those same low-frequency calls do something less obvious: they push vibrations into the ground, and other elephants appear to pick those vibrations up through their feet and trunks.
Put on the same rubber caveman mask a team of researchers once wore, walk across the University of Washington campus, and a good share of the local crows will start screaming at you.
A prairie dog standing sentry over its colony does more with a squeak than sound a generic alarm.
The Strait of Hormuz, the narrow sea passage linking the Persian Gulf to the Gulf of Oman and the open ocean, normally carries about 20 million barrels of oil a day.
For a long time, chronic constipation carried a name that hinted, without quite saying so, that it was not a proper illness.
China's Tianwen-2 spacecraft has reached Kamoʻoalewa and returned the first close-range image of the small asteroid that keeps pace with Earth.
Two researchers propose that the constant pull we never notice is quietly holding perception and the sense of self in place. The idea is elegant, testable in principle, and so far entirely unproven.
The first deep images from the James Webb Space Telescope contained a population that astronomers had not expected to see.
Brené Brown's two decades of shame and vulnerability research found something counterintuitive: kind people are rarely bad at giving. What blocks real intimacy is the far harder act of letting another person see the parts you routinely smooth over.
Brené Brown's two decades of shame and connection research point to a specific kind of solitude nobody teaches you to name — the loneliness of being surrounded by people who only want what you can give them.
In 1936, Danish seismologist Inge Lehmann read faint anomalies in seismograms from a 1929 New Zealand earthquake and deduced that Earth's core has a solid inner sphere nested inside a liquid outer shell — a conclusion still holding up nine decades later.
In 2013, seismologists reading the echoes of large earthquakes found a distinct iron sphere at Earth's centre, about 650 kilometres across, whose crystals point a different way from the layer around it — a fifth planetary layer nobody has ever seen.
When Curiosity rover landed in Gale Crater in August 2012, each wheel carried only twelve small holes, and those were deliberate: drilled at the factory as markers to help track how far the rover had rolled.
