- by Stuart ClarkA powerful wind in the early Universe may explain why some massive galaxies lived fast and died young by stopping forming stars far sooner than expected.
- by Stuart ClarkNew orbital mapping suggests Rosalind Franklinβs Oxia Planum landing site is part of a clay-rich region hundreds of kilometres wide, raising the possibility that it records a much larger watery episode in Marsβs early history.
- by Stuart ClarkThe Moon may preserve a record of the raw ingredients that helped life begin on Earth. New analysis of lunar samples returned by Chinaβs Changβe missions has revealed a diverse suite of organic compounds embedded within the soil.
- by Stuart ClarkAstronomers may not need to see the same dark matter signal everywhere in the Universe to confirm its existence. A new theoretical study suggests that dark matter could consist of more than one type of particle, potentially resolving a long-standing observational puzzle.
- by Stuart ClarkORLANDO, FLORIDA. Iβm a space-crazed Canadian who has somehow seen 11 launches across four different rockets since 2009. Iβve witnessed missions with astronauts, interplanetary spacecraft and (inevitably) Starlink, across two continents. But Artemis II took me by surprise yesterday (April 1). The Space Launch System was so bright it was almost painful to look at. […]
- by Stuart ClarkA machine learning pipeline developed in the UK has validated over 100 exoplanets in NASAβs TESS data, revealing rare planetary systems and sharpening estimates of how common close orbiting worlds really are.

- by Shanil ViraniThe 18.6-year cycle of the lunar standstill belongs to the Moon. But recognizing it belongs to us. For centuries, people have watched carefully enough, remembered long enough, and taught faithfully enough to discover patterns that unfolded across generations.

- by Alison KlesmanWeβre used to a lot of different natural things falling out of the sky. These can include snow, rain, and sometimes even frogs (yes, really). All of these relate to weather phenomena. Far more exotic things fall from the sky that are not related to weather. Earth is pelted by about 14 tons of micrometeoritesContinue […]

- A new pharmaceutical production method could allow astronauts on long space missions to "grow" fresh medicines on demand using plants. The work could also bring low-cost pharmaceutical production to resource-limited areas on Earth.
- Current plans for flagship telescopes in the 2040s are focused on answering a simple question – are we alone? Our best telescopes to date, such as the James Webb Space Telescope (JWST) have only given us tantalizing glimpses into the atmospheres or other worlds, but not enough to truly determine whether or not life as […]
- A small lump of rock pulled up from the Pacific Ocean seafloor in 1976 is giving scientists new clues about an ancient cosmic event. More than a hundred million years ago, two neutron stars collided. The resulting energetic kilonova sent a rain of long-lived elements, such as isotopes of plutonium, through space. Eventually, this stellar […]
- Switch off fusion and, for ten thousand years, nothing happens. Then the Sun begins a slow, strange death: shrinking, briefly brightening, and coasting on gravitational heat for tens of millions of years. And the neutrinos give the whole thing away in just eight minutes.
- A photon born in the Sun's core takes around 100,000 years to fight its way to the surface, bouncing through a random walk so inefficient that the light on your face is older than human civilization. Why the Sun's surface is a hundred-millennia-delayed broadcast.
