The James Webb Space Telescope has found evidence for thick water-ice clouds high in the atmosphere of Epsilon Indi Ab, one of the closest Jupiter-like worlds we can study directly.
In March 2025, Australia's new SKA-Low telescope took a picture of the sky dotted with 85 galaxies.
Two of the largest reported structures in the distant universe do not just look strange on their own.
Voyager 1, launched in 1977, is now so far from Earth that a radio signal travelling at the speed of light takes more than 22 hours to reach it.
Travel to another star at almost the speed of light and something strange happens to time.
We tend to picture astronauts drifting weightlessly in "zero gravity," as if the pull of the Earth simply stops a few hundred kilometres up.
It is easy to imagine the fastest spacecraft as the one with the most ferocious engine.
Earth can feel like an exception so complete that no statistic should be able to touch it.
Every large galaxy in the observable universe is thought to host a supermassive black hole at its centre.
Light from a galaxy called JADES-GS-z14-0 left on its way to us when the universe was only about 290 million years old, and the James Webb Space Telescope has confirmed both how far away it sits and how oddly grown-up it already looks.
On 1 April 2026, Artemis II lifted off from Kennedy Space Center with four people aboard Orion, beginning the first crewed lunar mission since Apollo 17 in 1972. By 6 April, the mission had moved beyond the familiar scale of low Earth orbit.
On 14 January 1966, Soviet chief designer Sergei Korolev died during surgery in Moscow at 59 — and two days later, Pravda printed his name and photograph for the first time. Until that obituary, the man who launched Sputnik and put Gagarin in orbit was known publicly only as the Chief Designer.
A shooting star is not a star. It is a meteor: the brief streak of light you see when a tiny piece of rock or dust from space slams into the top of Earth's atmosphere and starts to glow.
The problem was longitude. For most of the age of sail, mariners could determine their latitude, or north-south position, straightforwardly enough by measuring the height of the noonday sun above the horizon.
Astronomers using the James Webb Space Telescope have found a Jupiter-mass world orbiting a dead star, with an atmosphere so strange that its clouds appear to be soot condensing into diamond, and a composition that fits no known way of building a planet.
Titan, the largest moon of Saturn, is the only world besides Earth known to have rivers, lakes, seas, clouds and rain.
