The sky is blue. The oceans are blue. While science can explain them both, the reasons for each are entirely different.

The highest-energy particles could be a sign of new, unexpected physics. But the simplest, most mundane explanation is particularly iron-ic.

Wealth concentration among elites was common in ancient nations, but the scale on which it took place in Egypt’s 18th Dynasty was unprecedented.

Wind farms seem less productive when scientists incorporate more realistic atmospheric models into their output predictions.

“A modern five-day forecast is as accurate as a one-day forecast in 1980.”

The pseudoscience phrenology swept the popular imagination, and its practitioners made a mint preying on prejudices, gullibility, and misinformation.

65 million years ago, a massive asteroid struck Earth. Not only did Jupiter not stop it, but it probably caused the impact itself.

The idea of “absolute time” was our default for millennia. But time is relative, as gravity and motion both cause time to dilate.

Even with leap years and long-term planning, our calendar won’t be good forever. Here’s why, and how to fix it.

The existence of another watery world in the outer solar system may offer clues to how such seas form — and hope for another spot to search for life.

Over 50 years since humans last walked on the Moon, astronaut footprints and rover tracks are still visible. But they won’t last forever.

The closest star system to Earth, just over 4 light-years away, has three stars and at least one Earth-sized planet. Is it time to go there?

Engagement with generative AI is a business essential — but all companies should be vigilant.

Plants at room temperature show properties we had only seen near absolute zero.

The lithium-ion alternatives could help create a safer, greener future.

Back during the hot Big Bang, it wasn’t just charged particles and photons that were created, but also neutrinos. Where are they now?

Frontier, the ORNL supercomputer, used machine learning to perform 9.95 quintillion calculations per second.

Now that it’s fully commissioned, the James Webb Space Telescope begins its exploration of the Universe. Here are its first science images!

The first tests of optical communications far from Earth will take place aboard the asteroid-bound Psyche spacecraft

The classic picture of Jupiter’s great rocky core might be entirely wrong.

Before we discovered gravitational waves, multi-messenger astronomy got its start with light and particles arriving from the same event.

The James Webb Space Telescope has chosen 5 targets for its first science release. Here’s what we know on the eve of JWST’s big reveal!

It could make enough drinking water for a family of four.

Whenever someone waxes poetic about terraforming alien worlds, it’s worth taking a moment to consider the ethical implications of the proposal.

Photons come in every wavelength you can imagine. But one particular quantum transition makes light at precisely 21 cm, and it’s magical.

From the explosions themselves to their unique and vibrant colors, the fireworks displays we adore require quantum physics.

For the past 150+ years, the big ones have all missed us. But at some point, our good luck will run out.

Migrating our planet to a safer orbit might be the only way to preserve Earth after all the ice melts.

The National Ignition Facility just repeated, and improved upon, their earlier demonstration of nuclear fusion. Now, the true race begins.

Kahneman was a world-changing psychologist — even with his lesser known ideas on life satisfaction.
