At the European Space Agency’s technical heart in the Netherlands, engineers have spent the last five months unboxing and testing elements of Europe’s next space science mission. With the two main parts now joined together, Smile is well on its way to being ready to launch by the end of 2025.

New research based on an iron and sulphur mixture mirroring the Red Planet’s inner core suggests that Mars’ deep interior could be solid, like Earth.

A supermassive black hole that doesn't appear to be where we would expect seems to be travelling at more than a thousand kilometres per second – the result of a giant cosmic collision

A Trump administration plan would end the independence of the Nuclear Regulatory Commission, where similar oversight muzzling has led to nuclear disasters overseas

NASA engineers are turning off two instruments on Voyager 1 and Voyager 2 to ensure these twin spacecraft can continue exploring interstellar space.

Colorado-based company Lunar Outpost's MAPP rover is poised to land today (March 6) near the lunar south pole aboard the private Athena moon lander.

It is impossible for us to know exactly how another person's experience of the world compares to our own, but a new experiment is helping to reveal that colour is indeed a shared phenomenon

One week until a total lunar eclipse on March 13 turns the moon blood red. Here's everything you need to know.

The dividing line between gas giant planets and failed stars is blurry at best. The isolated planetary-mass object SIMP J013656.5+093347.3 could be either one. The distinction is largely semantic. However we choose to label and define it, the object displays a surprisingly complex atmosphere for an isolated object without any stellar energy input.

Planet Earth hangs in the background of this space age selfie.

Intuitive Machines' Athena lander is scheduled to touch down near the moon's south pole today (March 6). Here's how to watch it live.

Varda Space has successfully landed a reentry capsule in Australia, delivering critical data that could advance in-space manufacturing and hypersonic technologies.

Bacterial vaginosis, which is caused by bacteria overgrowing in the vagina, can be hard to treat, with women often experiencing recurring symptoms. Now it seems that asking their male sexual partners to use antibiotic pills and cream could be key to tackling the condition
