Hard Science

The ten greatest ideas in science form the bedrock of modern biology, chemistry, and physics. Everyone should be familiar with them.

The big-picture physics is simple – let gravity do its job.

In general, 5G is not a threat to human health or activities, but there are some legitimate questions about interference with airplane instruments.

The pulse took just 35 hours to cover the whole world.

We know more about the universe than what is beneath our feet. But Earth’s mantle holds subtle clues about our planet’s past.

The inside of every black hole leads to the birth of a new Universe. Could our Universe have arisen from one?

Shooting star or piece of space dust?

Impressive but deadly physics underlie catastrophic eruptions.

With a new telescope on the horizon, we reflect on the best pictures of space that came before.

On December 19 1972, astronauts Eugene Cernan, Harrison Schmitt and Ronald Evans splashed down safely in the Pacific Ocean, ending the Apollo 17 lunar mission. They were the last people to travel […]

The search for worlds outside our solar system has just turned up a planet, TOI-2257 b, with a truly extreme orbit.

Space missions in 2022 will include massive rockets and asteroid collisions. This is also the year space tourism starts to hit its stride.

A levitating vehicle might someday explore the moon, asteroids, and other airless planetary surfaces.

New technology is helping physicists move forward in the search for the Theory of Everything.

Water on Mars is key for human survival on the Red Planet, not just for drinking but for growing food and making fuel and oxygen.

If you put very fine black powder powder in a confined space it explodes in a cloud of heat, gas and noise.

The boiling new world, which zips around its star at ultraclose range, is among the lightest exoplanets found to date.

A newly discovered “ultrahot Jupiter” has the shortest orbit of any known gas giant.

Until now, researchers believed davemaoite could never be found on Earth’s surface.

A chemist explains the real reason your family dinner is such a risky ordeal.

From hellishly hot planets to water worlds, some distant planets are like nothing in our Solar System.

The Miller-Urey experiment showed that the building blocks of life could form in the primordial soup. But it overlooked one key variable.

On Nov. 15, 2021, U.S. officials announced that they had detected a dangerous new debris field in orbit near Earth. Later in the day, it was confirmed that Russia had […]

“Should they strike, each of them has an energy at impact equal to all of the nuclear weapons on Earth combined.”

Surface deformation or other signs of an impending explosion may not occur. Instead, supervolcanic eruptions can be much more insidious.

The findings include signs of flash flooding that carried huge boulders downstream into the lakebed.

Asymmetric organocatalysis is an environmentally friendly way of accelerating chemical reactions and creating specific types of molecules.

Much like computing technology, the Great Red Spot has been getting smaller and faster over the last few years.

Without Benjamin List and David MacMillan, chemists would still be using metals and enzymes to catalyze chemical reactions.

A new study shows that the Bernardinelli-Bernstein Comet is much larger than previously thought — potentially the largest ever spotted.
