There are suspicions that our solar system could harbour another large planet much further away than Pluto.

Upgrades to the hardware and software of the advanced observatory should allow astrophysicists to detect much fainter gravitational waves than before.
Our Sun will likely go out quietly – but not all such stars do. A new radio detection of a supernova can help us better understand these cosmic cataclysms.
Stars begin to expand when they run out of fuel and can become thousands of times larger, consuming any planets in the way. For the first time, astronomers have witnessed one such event.
There’s nothing weird happening with Mercury. In fact, most days of the year there’s at least one planet in retrograde.
A spacecraft set to launch this year will throw a spotlight on the mysterious ‘dark side’ of the universe.
Not all lunar eclipses are alike. An astronomer explains the science behind the slight dimming of the Moon on May 5, 2023.
Artificial intelligence tools are making waves in almost every aspect of life, and astronomy is no different. An astronomer explains the history and future of AI in understanding the universe.
For decades physicists have argued over the nature of the elusive dark matter that pervades the Universe. A clever new study uses gravitational lensing to bring new evidence to the debate.
The current race to the Moon is opening up opportunities for lunar astronomy.
An asteroid ‘the size of 33 armadillos’ might be a flight of fancy, but real astronomers measure celestial objects with units that are just as strange.
The Earth isn’t permanent, but it was here for four billion years before humans arrived and should be here for several billion more.
Calculating when and where exactly we can watch an eclipse in its full glory can be surprisingly hard.
Astronomers are hot on the search for new exoplanets – planets that lie beyond our Solar System – which might show potential for sustaining life.
The Jupiter Icy Moons Explorer and Europa Clipper missions will arrive at Jupiter in the 2030s and provide researchers with unprecedented access to the icy moons orbiting the gas giant.
History might give you the impression astronomical discoveries were only done by men. But women were participating in scientific expeditions of eclipses too, even though it wasn’t easy.
Medieval monks recorded hundreds of lunar eclipses. Centuries later, their descriptions are helping scientists unravel the role of volcanoes in historical climate change.
How might the space industry reduce its ecological footprint and better manage the debris it leaves in its wake?
Machine learning is becoming an indispensable tool in astronomy by sorting through enormous datasets from telescopes.
A US-led coalition and China are both planning to establish bases on the Moon. How the two nations will navigate actions on the Moon and how other countries will be involved is still unclear.
