The best evidence for dark matter is astrophysical and indirect. Do new lensing observations point to ultra-light, wave-like dark matter?

Upskilling prepares today’s workforce for tomorrow’s opportunities, positioning organizations for success in the future.

If we succeed in contacting them, will that seal humanity’s doom? One of the most wondrous questions of all concerns our place in the Universe. After 13.8 billion years of […]

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

And, if we have one, how close are we to it? No matter which direction we look in, or how far away our telescopes and instruments are capable of seeing, the […]

The idea of gravitational redshift crossed Einstein’s mind years before General Relativity was complete. Here’s why it had to be there.

America’s war in Southeast Asia is fading fast from memory. These maps offer a horrific reminder.

If nature were perfectly deterministic, atoms would almost instantly all collapse. Here’s how Heisenberg uncertainty saves the atom.

Just 13.8 billion years after the hot Big Bang, we can see 46.1 billion light-years away in all directions. Doesn’t that violate…something?

Some U.S. intelligence operatives have suggested foreign adversaries may be using “directed-energy” weapons against Americans.

SpinLaunch will cleverly attempt to reach space with minimal rocket fuel. But will physics prevent a full-scale version from succeeding?

Movie soundtracks don’t just help us recall the plot of a film; they also allow us to better understand its meaning.

Safety through technology is no bad thing—Nietzsche himself sought doctors and medicines throughout his life—but it can become pathological.

It had long seemed impossible that supermassive black holes could grow to such enormous sizes. But the biggest problem is now solved.

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

Metal really does sometimes stick to some people’s skin. Here’s the science of why. Every once in a while, a claim comes along that wildly challenges the mainstream scientific narrative. These […]

We just observed the first ‘lunar formation’ in an exoplanetary system. This one image, above, is the first to show moons actively forming around a planet. This colourful image shows […]

Many key inventions were unique: one-offs.

Is the Universe the same everywhere? Or are there truly ‘special places’ around? For practically all of human history, one assumption about our place in the Universe had long gone unchallenged: […]

Dark matter was thought to be cold and collisionless. But maybe that’s not the full story. If you look out at the Universe and measure all the matter out there, including […]

Discussions of human evolution are usually backward looking, as if the greatest triumphs and challenges were in the distant past.

Even with all the recent impacts we’ve seen, it might be more “foe” than “friend” to us.

Flow occurs when a task’s challenge is balanced with one’s skill.

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.

MIT scientists show how fast algorithms are improving across a broad range of examples, demonstrating their critical importance in advancing computing.

Although equal parts Hollywood blockbuster and Putinist propaganda, “Trotsky” still manages to capture the good, the bad, and the ugly of Russia’s revolutionary past.

And the one step we can take to show extraterrestrials we’re figuring it out. Every year, Earth’s meteor showers accomplish two important tasks. This composite photograph shows a large number of […]

Scalars, vectors, and tensors come up all the time in science. But what are they? One of the major goals of science is to describe our reality as accurately as possible. […]

Paintings played an important role in these ancient civilizations. Unfortunately, pigment is not nearly as durable as marble.

The densest objects that haven’t collapsed to black holes can tell us information about the Universe unlike anything else. Swarming through our own galaxy, we’ve detected quite a few bizarre objects: […]
