A strange gravitational wave is reviving an old idea: black holes older than the stars
A peculiar signal recorded by LIGO has astronomers entertaining a radical possibility — that it came from primordial black holes born in the universe's first instants, which could also help solve the dark matter problem.

After 11 years reading the Martian air, MAVEN goes quiet
NASA has ended its MAVEN mission after more than a decade studying how Mars lost its atmosphere. The orbiter rewrote our understanding of why a once-wet world dried out — and found auroras nobody expected.

NASA's Moon base stops being a slogan and starts signing contracts
At a Moon Base event in Washington, NASA named the commercial hardware that will build out a lunar surface presence — pressurized rovers for crews to drive and uncrewed cargo landers — with the first robotic delivery targeted for as soon as this fall.

Six toaster-sized satellites are about to become one giant radio telescope
NASA's SunRISE mission, targeting a summer 2026 launch, will fly six small satellites in formation so they act as a single radio telescope ten kilometers wide — built to trace the solar storms that threaten astronauts and power grids.

Mark the date: on August 12, 2026, the Moon's shadow returns to Europe
A total solar eclipse on August 12, 2026 will cross Greenland, Iceland, and Spain — the first to touch mainland Europe since 1999. Here's where totality falls, how long it lasts, and who gets a partial show.

One planet, two weathers: Webb catches an ultra-hot world with a split atmosphere
Using JWST, astronomers have measured a clear difference between the morning and evening edges of the ultra-hot gas giant WASP-121b — the same planet showing two distinct atmospheres at once, separated only by the line where day meets night.

In 2029 an asteroid will pass closer than our satellites — and two spacecraft will be waiting
On April 13, 2029, the asteroid Apophis will skim just 32,000 kilometres above Earth, visible to the naked eye for billions of people. It will miss us — but NASA and ESA are sending spacecraft to watch what Earth's gravity does to it, a free experiment in planetary defense.

The new Moon rush: a fleet of private landers is heading for the lunar surface
NASA stopped building its own small Moon landers and started buying rides instead. The result is a wave of commercial spacecraft from Intuitive Machines, Firefly, and others aiming for the lunar surface in 2026 — a bumpy, fast-moving experiment in outsourcing exploration.

The little moon that sprays its ocean into space — and why it tops the list for life
Enceladus is a frozen moon of Saturn barely 500 kilometres across, but it does something no other world is known to do: it jets plumes of its hidden ocean directly into space, where a spacecraft can taste them. What's in those plumes has made it a prime target in the search for life.

Europe's 'dark universe detective' is building a 3D map of the invisible cosmos
Most of the universe is made of things we cannot see — dark matter and dark energy. ESA's Euclid telescope is surveying billions of galaxies across ten billion years of history to map that invisible scaffolding, with its first major cosmology data release due this October.

A NASA spacecraft is gliding toward a world made largely of metal
Psyche is cruising on a faint blue glow of ion thrust toward an asteroid unlike any we've visited — a body that may be the exposed metal heart of a shattered protoplanet, and a chance to see the kind of core that hides inside Earth.

The highest clouds on Earth glow electric blue at midnight — and their season is starting
On summer nights, long after sunset, a rare kind of cloud can shine an eerie electric blue near the horizon. Noctilucent clouds form at the very edge of space, and June and July are prime time to catch them from northern latitudes.
