The long-standing mystery of how supermassive black holes grew so huge so quickly could be solved by decaying dark matter

The second-closest planet to the sun is more geologically active than we thought and could have more than 17,000 venusquakes a year

Spanning 23 million light years, or 220 Milky Way galaxies, a set of giant, newly discovered black hole jets known as Porphyrion may change our understanding of black holes and the structure of the universe

As the space industry evolves, we need a new set of international regulations to decide who is responsible for safety, the number of satellites in space, and more

Exoplanets in binary star systems usually orbit both stars, but astronomers have now spotted three planets orbiting one or the other star in a pair

Nearly imperceptible quantum flickers used to limit how precisely we could detect the way space-time ripples, but squeezing the laser light used in detectors overcomes this and doubles the number of gravitational waves we can see

Genetic analysis shows that microbes growing inside the International Space Station have adaptations for radiation and low gravity, and may pose a threat to astronauts

Medically evacuating an astronaut from space is difficult and expensive, and a new model predicts that one in three long-duration moon missions may require it

A distant planet should have been consumed when its star expanded to become a red giant, perhaps offering insights into planetary migration

Astronomers listened for radio signals emanating from planets in the TRAPPIST-1 system, but found no evidence of any interplanetary communications

These dazzling images taken by NASA's Hubble Space Telescope are from the upcoming book Cosmos: Explore the wonders of the universe, which has a foreword by astrophysicist Becky Smethurst

Astronomer Jo Dunkley is planning to use the Simons Observatory to snare evidence for inflation, the theory that the universe expanded at incredible speed after its birth

Astronomers have detected an exoplanet around Barnard’s star, one of the sun’s closest neighbours, but it is too hot for liquid water or life

Cracks running through samples of asteroid Ryugu were probably formed by the repeated thawing and freezing of water inside it, which could have helped asteroids like this carry the building blocks of life to early Earth

A computer simulation suggests that some collisions between exotic, hypothetical stars would make space-time ripple with detectable waves

The first 18 satellites of a planned Chinese mega constellation are brighter than all but 500 stars in the sky, raising fears of a huge impact on astronomy

Andrew McConnell's otherworldly photograph captures a Russian cosmonaut in front of the just-landed Soyuz MS spacecraft in Kazakhstan's remote grasslands

How did the supermassive black holes we’re now seeing in the early universe get so big so fast? Astrophysicist Sophie Koudmani is using sophisticated galaxy simulations to figure it out

The European Space Agency is sending a probe to get a closer look at the asteroid Dimorphos, which had its orbit altered by NASA’s DART mission in 2022

Bacteria grown from carbon compounds in asteroids could be turned into a kind of nutritionally balanced milkshake

A detector on the International Space Station found signatures of unexpectedly abundant antimatter – which may have been created in clashes of dark matter particles

The European Space Agency's Hera spacecraft must be thoroughly tested before being sent to investigate the aftermath of the collision of NASA's DART probe with Dimorphos

The ion tail of C/2023 A3 (Tsuchinshan-ATLAS) could appear as a blue streak across the northern hemisphere sky during October, in a rare event thought to happen only every few decades

SpaceX claims the fifth test flight of its Starship rocket will happen “within days”, but the Federal Aviation Administration has not yet approved the launch

My first sight of Saturn through a telescope inspired my love of space. Dig out your telescopes or visit your local astronomy club, and you may be lucky enough to spot our sixth planet's stunning thick band of rings, says Leah Crane

A 6000-kilogram spacecraft will embark on a six-year journey to Jupiter to explore whether its icy moon Europa has the conditions to support life

Meet NASA’s NEO Surveyor, the space telescope identifying hazardous asteroids and comets within 48 million kilometres of Earth’s orbit

The Euclid space telescope's massive “cosmic atlas” promises to shed light on fundamental questions in physics and cosmology

The first “failed star” ever discovered has been a weird outlier since it was found nearly 30 years ago. New observations show that it is unusually massive because it isn’t a single star after all

General relativity teaches us that observing a black hole is all a question of perspective – and technique, says Chanda Prescod-Weinstein

Moin Hussain's debut feature film Sky Peals sees a man discover his father may be from outer space. Part sci-fi, part family drama, part coming-of-age tale, it is odd and otherworldly

A nearby star that exploded some 3 million years ago could have removed all dust smaller than a millimetre from the outer solar system

Complex carbon-based molecules crucial to life on Earth originated somewhere in space, but we didn't know where. Now, huge amounts of them have been spotted in a huge, cold cloud of gas
