Exoplanets. They're very small, and very far away. We usually have to detect them by indirect means. Direct images are rare, and not very detailed. Even working out what's in their atmosphere is difficult. So you'd think trying to analyse their int

If we're going to support ourselves on off-world bases then we're going to need to find a way to grow our own food, and now we've got more than a Matt Damon film to suggest it's possible – experiments run using lookalikes of Moon and Mars so

One key to a longer life could be a quieter brain without too much neural activity, according to a new study that examined postmortem brain tissue from extremely long-lived people for clues about what made them different from people who died in the

The Egyptian government is hailing the discovery of more than 20 wooden coffins as "one of the largest and most important" archaeological finds in the past few years.

As if we didn't have enough to worry about, the vast ice sheets of Antarctica are still releasing radioactive chlorine, a new study has confirmed – the remnants of nuclear weapons tests carried out in the 1950s.

Record warm temperatures above Antarctica over the coming weeks are likely to bring above-average spring temperatures and below-average rainfall across large parts of New South Wales and southern Queensland.

In November 1572, a star exploded. It brightened in the night sky, until it was visible to the naked eye - a jaw-dropping phenomenon observed and documented by astronomers around the world, none more extensively than Danish astronomer Tycho Brahe,

Male and female mouse brains could have significant differences that reach right down to the cellular level, according to a new discovery.

The sea wastes nothing.

From tiny snowflakes to the jagged fork of a lightning bolt, it's not hard to find examples of fractals in the natural world. So it might come as a surprise that, until now, there have remained some places these endlessly repeating geometrical patt

OpenAI, the artificial intelligence development company co-founded by Elon Musk, just built an AI-powered robot hand that can solve a Rubik's cube by itself.

Hurricanes are one thing. Earthquakes are another. But these hazardous events aren't mutually exclusive, and sometimes one can even feed the other.

NASA made history Friday morning when astronauts Christina Koch and Jessica Meir stepped outside the International Space Station to replace a faulty battery charger.

More than 2,600 years ago, strange red clouds over Mesopotamia drew the attention of soothsayers across the land. Their royal reports have now helped confine the date of a severe solar storm that washed over the planet.

You might have heard the idea that being an only child means you're more likely to be selfish, spoilt, and self-centred – but the results of a new study show no link between being an only child and being more narcissistic.

In order to be considered habitable, a planet needs to have liquid water. Cells, the smallest unit of life, need water to carry out their functions. For liquid water to exist, the temperature of the planet needs to be right.

Many of you will be aware of how fatty build-ups in the arteries can increase the chances of developing heart problems, but now scientists have found early evidence the same sort of clogging could happen in the lungs – and it might be linked to a

What if alien spacecraft are already in our midst – and we don't know about them because they're tiny nano-structures? That's the new idea put forward by one scientist seeking to explain the Fermi paradox.

For a fiery phenomenon we most commonly associate with magma-spewing mountaintops, it's easy to forget that some 70 percent of all Earth's volcanism takes place under the ocean waves.

Psychologists have identified an important trait that could be shared by truly humble people - something called 'hypo-egoic nonentitlement'.
