New theories of wormholes—postulated tunnels through spacetime—explore whether they could be traversable by humans.

It's tricky to figure out what Earth might have looked like in the early years before life emerged. Geological detectives have now obtained more evidence that it was rather different to the planet we live on today.

Oxygen is life to animals like us. But for many species of microbe, the smallest whiff of the highly reactive element puts their delicate chemical machinery at risk of rusting up.

The question of how life on Earth got started has long intrigued us, and new research suggests that primordial lightning strikes – perhaps over the course of a billion years – could have played a crucial role in sparking life on this planet.

The origin and identity of a massive space object that careened past Earth in 2017 have remained a mystery ever since.

Vaccines are amazing, life-saving innovations, and the COVID-19 vaccines are no different. As with any medical procedure, there are potential drawbacks to using them, but we know from massive pieces of scientific research that the COVID-19 vaccine

SpaceX was down to its last rocket, which was flying aboard a C-17 jet over the Pacific. When it began to crumple, Zach Dunn dove in headfirst.

A deadly hospital superbug has been discovered on a remote island beach, marking the first time researchers have seen this multidrug-resistant organism in the "wild".

The menagerie of bacterial and fungal species living among us is ever growing - and this is no exception in low-gravity environments, such as the International Space Station (ISS).

NASA’s newest rover recorded audio of itself crunching over the surface of the Red Planet, adding a whole new dimension to Mars exploration.

NASA put the core stage of its new mega-rocket through its most grueling test yet on Thursday.

Have you ever thought to yourself, "Gosh, I sure wish I could feel extremely small and awed right now"? Do we ever have the solution for you!

Two new scientific reviews have backed up all the previous research we've seen into 5G technology to date, finding that the next-generation connectivity standard doesn't pose any health risks.

A "lunar ark" hidden inside the Moon's lava tubes could preserve the sperm, eggs and seeds of millions of Earth's species, a group of scientists has proposed.

It collided with Jupiter in 1994, but Comet Shoemaker-Levy 9 still apparently has things to teach us about the Solar System's largest planet.

The question of how life on Earth got started has long intrigued us, and new research suggests that primordial lightning strikes – perhaps over the course of a billion years – could have played a crucial role in sparking life on this planet.

The very first vertebrates to walk on our planet might have done so in the great ocean deep, millions of years before their later relatives transitioned to the land.

What we thought may have been an off-switch for star formation doesn't appear to work that way after all.
