Look out at a distant object, and you’re not seeing it as it is today. It’s size, brightness, and actual distance are all different.

Psychological safety plays a key role in fostering innovation and collaborative group dynamics where all team members feel comfortable being themselves.

If you want to know what the Universe is like, you have to look at it in the right way. Only by observing it can we know what the Universe is […]

Thales may have known the famous theorem perhaps as much as half a century before Pythagoras.

It could evolve, strengthen, decay, or not be alone. Our known Universe contains matter, radiation, and dark energy. While matter (both normal and dark) and radiation become less dense as […]

A new study found the possible reason why some dwarf galaxies appear to not have dark matter.

You might be inclined to modify gravity instead, but those ideas have grossly unequal evidence supporting them. What is it, exactly, that you’re supposed to do when the predictions of […]

Prosthetic arms can cost amputees $80,000. A startup called Unlimited Tomorrow is aiming to change that by making customized 3D-printed bionic arms for just $8,000.

In theory, the fabric of space could have been curved in any way imaginable. So why is the Universe flat when we measure it?

The Crab Nebula goes back to 1054, opening a window into our cosmic past. On July 4, 1054, Chinese astronomers recorded a “guest star” in the Taurus constellation. A ‘guest star’ […]

Even 13.8 billion years after the Big Bang, we can reconstruct the first 3 minutes. About 100 years ago, we began to truly understand the nature of the Universe for the […]

Proteus could someday be used to create extremely strong and lightweight armor and locks.

It wasn’t the birth of space and time. But it was truly essential to our cosmic story. For more than 50 years, we’ve had definitive scientific evidence that our Universe, as […]

A unique exoplanet without clouds or haze was found by astrophysicists from Harvard and Smithsonian.

Scientists discover burrows of giant predator worms that lived on the seafloor 20 million years ago.

It could lead to a massive uptake in those previously hesitant.

Once only dark energy remains, empty space still won’t be completely empty. Imagine, if you dare, the very end of the Universe. The stars — past, present, and future — have all burned out. […]

There is no going “back to normal.”

Nihilism is not a choice or intellectual commitment, but a feeling that simply arrives.

In Sun-like stars, hydrogen gets fused into helium. In the Big Bang, hydrogen fusion also makes helium. But they aren’t close to the same.

The Hubble Space Telescope, 32 years after its launch, broke the all-time record for most distant star. It won’t do better.

A school lesson leads to more precise measurements of the extinct megalodon shark, one of the largest fish ever.

Going to smaller and smaller distance scales reveals more fundamental views of nature, which means if we can understand and describe the smallest scales, we can build our way to […]

Whatever’s lurking out there, it isn’t all, or even mostly, normal matter. When it comes to the Universe, it’s only natural to wonder what, exactly, it is that makes everything up. […]

It might not feel that way, but a 95% dark Universe really is the best game in town. No matter how much we might try and hide it, there’s an enormous […]

The past ~4 billion years have been an incredibly successful, unbroken run for life on Earth. The future won’t be nearly so bright.

The four-color theorem was one of the past century’s most popular and enduring mathematical mysteries.

The bizarre discovery could pave the way for advances in regenerative medicine for humans.

Despite the claims of one of Earth’s newest Nobel Laureates, the data doesn’t lie. One of the greatest scientific successes of the past century was the theory of the hot Big […]

The Rijksmuseum employed an AI to repaint lost parts of Rembrandt’s “The Night Watch.” Here’s how they did it.
