A rock found last year on the surface of Mars offered tantalising evidence that life once existed on the Red Planet. Now scientists have found yet more evidence that could point to the existence of ancient organisms – but we can't know for certain without returning samples to Earth

For women going through perimenopause, there is no shortage of advice on how to deal with the symptoms – but which strategies show real results, and which are social media hype?

Samples retrieved from asteroid Ryugu indicate that it once had flowing water in far greater volumes than previously thought possible, suggesting that similar objects may have played a role in delivering vast quantities of water to Earth

The public can submit names to travel along with four astronauts on an orbital journey to the moon next year

Depending on where you smack a planet-threatening asteroid, it might ricochet back to Earth.

The Perseverance rover’s new findings set the stage for bringing Martian samples back to Earth to test whether microbes once inhabited the Red Planet

Dinner is served aboard the International Space Station! One tray features shrimp cocktail on whole grain wheat crackers, while the other holds sushi made with seaweed, Spam, tuna, and rice.

Spacetime ripples from a black hole collision across the cosmos have confirmed weird aspects of black hole physics

"GW250114 is the loudest gravitational wave event we have detected to date; it was like a whisper becoming a shout."

"There is no evidence of microbes on Mars today, but if any had been present on ancient Mars, they too might have reduced sulfate minerals to form sulfides in such a lake at Jezero crater."

The "Tranche 1 Transport Layer" network will eventually consists of 126 satellites in low Earth orbit.

Scientists will not find a simple answer to how autism arises, despite Robert F. Kennedy, Jr.’s promise to announce its causes sometime this month. Here’s what makes the condition so staggeringly complex

Chile is a hotspot for telescopes peering up into deep space to study structures like stars, black holes, dark matter and galaxies.

Live in the eastern hemisphere? If skies are clear, you have a chance to see a remarkable sight this Sunday night into Monday morning: the ‘Blood Moon’ of a total lunar eclipse. The eclipse favors the Indian Ocean region in its entirety. Europe sees the eclipse already underway at Moonrise, while Australia catches it in progress at Moonset. Only the Americas sit this one out in person... though you can still catch it live online.

One of the most difficult parts of astronomy is understanding how time affects it. The farther away you look in the universe, the farther back you look in time. One way this complicates things is how objects might change over time. For example, a supermassive black hole at the center of a galaxy in the early universe might appear one way to our modern telescopes, but the same supermassive black hole might appear completely differently a few billion years later. Understanding the connection between the two objects would be difficult to say the least, but a new paper from researchers at the University of Science and Technology in South Korea describes one potential parallel, between the recently discovered “Little Red Dots” of the early universe and “BlueDOGs” of the slightly later universe.
