James Webb has found evidence for thick water-ice clouds on Epsilon Indi Ab, one of the closest Jupiter-like worlds we can study directly — a discovery that didn’t overturn every atmospheric model, but exposed how many of them had been leaving out the very thing now shaping the planet’s sky.

In March 2025, Australia's new SKA-Low telescope photographed 85 galaxies using just 1,024 of its planned 131,072 antennas — less than one percent of its full power, and the image was already beyond what scientists hoped for

Two enormous structures — the Giant Arc and the Big Ring — appear in the same region of deep space at the same cosmic distance, a pairing so unexpected that Alexia Lopez, one of the astronomers who discovered them, says current cosmology struggles to explain even one of them, let alone both together.

The Voyager 1 probe, launched in 1977, is now so far from Earth that a radio signal travelling at the speed of light takes over 22 hours to reach it, and it is still sending data back from interstellar space on a power source the size of a car battery

If you could travel to another star system at almost the speed of light, you might age only a few years on the journey — while the people you left behind could age by generations, or even be gone for centuries.

A galaxy confirmed this January formed just 290 million years after the Big Bang, and the part astronomers cannot explain is that it is far too large, far too soon, as if the early universe was building things it was not supposed to be able to build yet.

On April 1 this year, four astronauts left Earth on humanity’s first crewed lunar mission since 1972, and by April 6 they had flown farther from home than any humans in history — returning with the strange perspective astronauts have described for decades, where Earth stops looking like a place and starts looking like something impossibly fragile.

Titan is the only world besides Earth known to have rivers, lakes, seas, clouds and rain — except its “water” is methane and ethane, flowing across a surface frozen to minus 179 degrees Celsius. And in June 2026, scientists held the first Humans to Titan Summit, beginning to map what a crewed mission to Saturn’s largest moon would actually require.

Scientists assumed every cave on Mars formed from ancient lava, but a team from Shenzhen University has now found eight that water carved through soluble rock — a process never before confirmed on the Red Planet

Scientists expected Pluto to be a frozen, ancient world scarred by billions of years of impacts. But when New Horizons finally arrived in 2015, it found something stranger: smooth young plains with almost no craters, signs of flowing nitrogen ice, possible ice volcanoes, and a layered blue haze in an atmosphere no one expected to look so complex

Carl Sagan spent years trying to persuade NASA to take a picture many saw as scientifically pointless: Earth from more than 6 billion kilometres away, reduced to a pale blue dot smaller than a pixel. Voyager 1 finally captured it in 1990 — and that tiny speck became one of the most haunting images in human history.

In 2025, astronomers found one of the largest spinning structures ever reported in the universe: a cosmic filament roughly 50 million light-years long, containing nearly 300 galaxies. Many of its galaxies appear to rotate in sync with the filament itself — a vast, coordinated motion that challenges current models of how galaxies gain their spin.

In 2025, astronomers discovered Eos, the closest dark molecular cloud ever found — a vast crescent of molecular hydrogen just 300 light-years from Earth. It is so enormous on the sky that, if human eyes could see its ultraviolet glow, it would stretch about 40 times the width of the full Moon.

Euclid, the European telescope built to map the dark universe billions of light-years away, spent a single 26-hour stretch staring into the crowded center of the Milky Way and resolved more than 60 million stars, handing NASA's Roman mission a reference map for the planet hunt it begins after launching in late August
