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

Although the Big Bang occurred at an instant in time long ago, we still see the light from it. Will the evidence ever disappear completely?

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

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

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

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!

The odds are slim, but the consequences would be devastating. Here’s what would happen, plus how to avoid it.

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

The most celebrated genius in human history didn’t just revolutionize physics, but taught many valuable lessons about living a better life.

For some reason, when we talk about the age of stars, galaxies, and the Universe, we use “years” to measure time. Can we do better?

The author of classics like “A Farewell to Arms” and “The Sun Also Rises” is known and loved for his simple yet effective writing style. Here’s how to imitate it.

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

If there are human-sized creatures walking around on other planets, would we be able to view them directly?

High-frequency oscillations that ripple through our brains may generate memory and conscious experience.

Empty, intergalactic space is just 2.725 K: not even three degrees above absolute zero. But the Boomerang Nebula is even colder.

Think twice before stepping on that crunchy top layer of soil.

The big question isn’t whether the Universe is expanding at 67 or 73 km/s/Mpc. It’s why different methods yield such different answers.

In the infant Universe, particle physics reigned supreme.

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

From how life emerged on Earth to why we dream, these unanswered questions continue to perplex scientists.

Most potentially hazardous asteroids remain unidentified. NEO surveyor could change that, but only if it’s funded, and soon.

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

Astrophysicist Michelle Thaller explains how a solar storm could wipe out civilization… and what we can do to prevent catastrophe.

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

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

Science continues to amplify our view of reality.

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

We haven’t seen a partial eclipse lasting this long since 1440, and won’t again until 2669. North America is perfectly positioned for 2021’s.

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

Every timekeeping device works via a version of a pendulum — even the atomic clocks that are accurate to nanoseconds.
