The Andromeda galaxy is the most distant thing you can see with the naked eye, and the light reaching your eyes from it tonight left some 2.5 million years ago, long before our own species existed.

Tom Mueller spent nearly two decades building the Merlin and Draco engines that helped make SpaceX possible, and now his in-space mobility company has crossed $1 billion in venture funding before its fastest vehicle has flown to geostationary orbit

3I/ATLAS is only the third confirmed interstellar object ever detected passing through our solar system. It may be older than the Sun itself, and Webb observations show it is carrying an unusually carbon dioxide-rich coma as it swings past once before leaving for interstellar space forever.

Earth quietly picks up tiny second moons from time to time, small asteroids briefly caught by our gravity before they wander off again, which means our planet has carried far more moons than the single one most people ever notice.

The first humans on Mars will not just be explorers crossing a red desert. They will be radiation workers, dust-control technicians and weather-watchers on a planet where the danger is less dramatic than constant.

The James Webb telescope keeps finding early galaxies that look brighter, bigger and more mature than astronomers expected, forcing researchers to rethink how quickly the first galaxies formed stars and assembled after the Big Bang.

In 1959, the Soviet Luna 3 probe swung around the far side of the Moon and took 29 grainy photographs of a hemisphere humans had never seen, then developed the film onboard and scanned the negatives with a flying-spot beam to radio them back across nearly 480,000 kilometres of vacuum

There are millions of objects in our own solar system that have never been seen and the facility that will find them is now just months from starting its decade-long survey

Parker Solar Probe has flown through the Sun’s outer atmosphere, the corona, where temperatures soar into the millions of degrees even though the visible surface below is far cooler — one of the strangest long-running puzzles in solar physics.

An AI trawled through 35 years of Hubble images and found more than 800 strange objects that had never been documented before, showing that one of astronomy’s most famous archives is still hiding discoveries in plain sight

Voyager 1, the first human-made craft to enter interstellar space, carries a golden record of Earth’s music and greetings — a message launched into the dark, even though it will not pass near another star for about 40,000 years.

We picture the asteroid belt as a dense field of tumbling rock, but the spaces between its objects are so vast that spacecraft can fly straight through it, with the chance of hitting anything almost nil.

Mercury is not the hottest planet in the solar system despite sitting closest to the Sun, because Venus traps so much heat under its thick atmosphere that it stays hotter day and night.

When Soviet engineers launched the N1 moon rocket from Baikonur in July 1969, it climbed about 200 metres before falling back onto Site 110 and exploding with an estimated seven kilotons of energy, destroying a launch pad in a disaster the USSR kept hidden for two decades
