Chernobyl’s exclusion zone, emptied of most human activity after the 1986 nuclear disaster, is now home to
Forty years after the Chernobyl reactor explosion, the exclusion zone has become an unexpected refuge for large mammals, including wolves, lynx, deer, wild boar, moose and introduced Przewalski’s hors
Titan has rivers, rainfall, lakes and a slow hydrological cycle exactly like Earth's, except that every drop of it is liquid methane and the rock the rivers run over is water ice
Titan, Saturn’s largest moon, is the only place besides Earth known to have stable liquid on its surface. It features rivers, rain, clouds, lakes, and seas formed by a methane-based hydrological cycle
Titan has rivers, rainfall, lakes and a slow hydrological cycle exactly like Earth's, except that every drop of it is liquid methane and the rock the rivers run over is water ice
Titan, Saturn’s largest moon, is the only place besides Earth known to have stable liquid on its surface, but its landscape is shaped by a very different substance: liquid methane and ethane instead o
It's tempting to assume faster engines make faster spacecraft, but Parker Solar Probe's record 430,000 miles per hour came mostly from gravity: seven Venus flybys spent nearly seven years bending its orbit closer to the Sun, until the Sun's own pull accelerated it faster than any human-made object in history.
Parker Solar Probe’s record speed of about 430,000 miles per hour was achieved not mainly through engine power, but through gravity and careful orbital design. Launched in August 2018 aboard a Delta I
We think of astronauts as floating in zero gravity, but the International Space Station is still deep inside Earth’s pull, where gravity is nearly 90% as strong as it is on the ground. What looks like weightlessness is really the station and its crew falling around the planet at about 28,000 kilometres per hour.
Astronauts on the International Space Station (ISS) are not experiencing “zero gravity” in the literal sense. The station orbits about 400 kilometers above Earth, where gravity is still about 90% as s
When a human and a dog gaze into each other's eyes, both of them release oxytocin — the same hormone released between a human mother and her infant during nursing — and Japanese researchers reported in 2015 that this cross-species chemical feedback loop appears to be unique to dogs and their humans and does not occur in wolves
A 2015 study by Japanese researchers found that when humans and dogs make mutual eye contact, both species release oxytocin, a hormone strongly linked to social bonding. This “positive feedback loop”
Mount Everest is the highest point above sea level, but because the Earth bulges at the equator, the summit of a volcano in Ecuador sits farther from the centre of the planet, making it the closest piece of land on Earth to outer space.
Mount Everest is the highest point on Earth above sea level, with an official height of 8,848.86 metres, but it is not the point farthest from the planet’s centre. That distinction belongs to Chimbora
There is a single satellite launched by the US Navy in 1964 that is still in orbit, still transmitting, and still being used by amateur radio operators around the world — and nobody at the Navy has been in charge of it for decades
Transit 5B-5, a U.S. Navy navigation satellite launched on December 28, 1964, remains in orbit, still transmitting, and still detectable by amateur radio operators more than 60 years later. It was par
The Soviet Lunokhod 1 rover went silent on the Moon in 1971, then scientists found its lost reflector in 2010 and got a signal bright enough to reopen a forgotten corner of lunar science
Lunokhod 1, the Soviet Moon rover that stopped responding in 1971, was rediscovered as a scientific target in 2010 after nearly 40 years of uncertainty about its exact location. Launched on November 1
