In just a few seconds, a gamma-ray burst blasts out the same amount of energy that the Sun will radiate throughout its entire life.

Once water gets more than about 200 feet deep, building on the sea floor is out of the question.

Make Sunsets is bringing solar geoengineering from sci-fi to reality.

Quantum wormholes are mathematically possible — but might also be physically impossible. Physicist Janna Levin explains Hawking’s famous information paradox.

Nike athlete and famed Peloton instructor Tunde Oyeneyin shares how she turned her pain into purpose.

Its implications go well beyond the Earth itself, affecting even the future of space travel.

With the discovery of Porphyrion, we’ve now seen black hole jets spanning 24 million light-years: the scale of the cosmic web.

Why “audio gaps” in video meetings wear us out — and why we need the meaningful relationships forged in communal workspaces.

It’s not just fun: DNA origami has the potential to revolutionize engineering at the nanoscopic scale.

“Having more stem cell activity is good for regeneration, but too much of a good thing over time can have less favorable consequences.”

No matter how you define the end, including the demise of humanity, all life, or even the planet itself, our ultimate destruction awaits.

Ever since the Big Bang, cataclysmic events have released enormous amounts of energy. Here’s the greatest one ever witnessed.

This research team is working out how to detect extraterrestrial cells in the liquid water ocean hidden beneath Enceladus’s icy crust.

Our cosmic home, planet Earth, has been through a lot over the past 4.5 billion years. Here are some of its most spectacular changes

This supremely simple hack can help you establish good habits, break bad ones, and guard against failure.

There’s really only one mistake you can make: continue doing the same thing you already know is hurting you and expect a different result.

Perhaps the most remarkable fact about the Universe is simply that it, and everything in it, exists. But what’s the reason why?

Gamma-ray bursts are among the most energetic cosmic events of all. On October 9, 2022, a remarkable one occurred: the brightest ever seen.

Physicists just can’t leave an incomplete theory alone; they try to repair it. When nature is kind, it can lead to a major breakthrough.

The DUNE project will beam tiny neutrinos across vast distances. But the first step involved moving a heavier material: 1 million tons of rock.

If there’s life lurking on the moons of Saturn and Jupiter, could our instruments even detect it?

How Stacy Madison — founder of Stacy’s Pita Chips and BeBOLD Foods — discovered that reinvention is not a one-off deal but an ongoing process.

The concept of ‘relativistic mass’ has been around almost as long as relativity has. But is it a reasonable way to make sense of things?

Realizing that matter and energy are quantized is important, but quantum particles aren’t the full story; quantum fields are needed, too.

Freethink’s weekly countdown of the biggest space news, featuring Starship’s second test flight, a new “dark mysteries” telescope, and more.

NASA astrophysics, which gave us Hubble, JWST, and so much more, faces its greatest budget cut in history. All future missions are at risk.

Our greatest tool for exploring the world inside atoms and molecules, and specifically electron transitions, just won 2023’s Nobel Prize.

Nobel Laureate Roger Penrose, famed for his work on black holes, claims we’ve seen evidence from a prior Universe. Only, we haven’t.

The majority of people in every country support action on climate, but the public consistently underestimates this share.

From quarks and gluons to giant galaxy clusters, everything that exists in our Universe is determined by what is (and isn’t) bound together.
