Would you confess your crimes to a skeleton with “an unnatural ghastly glow”? One inventor thought you would.

We live in a four-dimensional Universe, where matter and energy curve the fabric of spacetime. But time sure is different from space!
Now that it’s fully commissioned, the James Webb Space Telescope begins its exploration of the Universe. Here are its first science images!
The Universe isn’t just expansion, but the expansion itself is accelerating. So why can’t we feel it in any measurable way?
Each year in mid-August, Earth plows through the debris stream of an enormous comet, creating the Perseids. 2023’s show will be magnificent!
The researchers and patients are excited to see if color vision will develop over time.
The largest particle accelerator and collider ever built is the Large Hadron Collider at CERN. Why not go much, much bigger?
From the explosions themselves to their unique and vibrant colors, the fireworks displays we adore require quantum physics.
In a study involving mice, scientists used two different techniques — one optogenetic and one pharmacologic — to recover “lost” memories.
“In that conversation with Laozi’s text, I began to see the shape of my own life, the questions that opened seams, the patterns that pooled and shimmered.”
Some 13.8 billion years ago, the Universe became hot, dense, and filled with high-energy quanta all at once. Here’s what it was like.
In 1920, astronomers debated the nature of the Universe. The results were meaningless until years later, when the key evidence arrived.
If it weren’t for the intricate rules of quantum physics, we wouldn’t have formed neutral atoms “only” ~380,000 years after the Big Bang.
From the Big Bang to dark energy, knowledge of the cosmos has sped up in the past century — but big questions linger.
The giant impact theory suggests our Moon was formed from proto-Earth getting a Mars-sized strike. An exoplanet system shows it’s plausible.
As particles travel through the Universe, there’s a speed limit to how fast they’re allowed to go. No, not the speed of light: below it.
The European Space Agency’s Solar Orbiter recently captured images that could help scientists better under the mysterious physics of our Sun.
With infrared capabilities and image sharpness far beyond Hubble’s limits, JWST looked at Hubble’s deepest field, revealing so much more.
In many ways, we are still novices playing with toy models seeking to understand the stars.
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!
When the Universe was first born, the ingredients necessary for life were nowhere to be found. Only our “lucky stars” enabled our existence.
As early as we’ve been able to identify them, the youngest galaxies seem to have large supermassive black holes. Here’s how they were made.
The Hubble Space Telescope, 32 years after its launch, broke the all-time record for most distant star. It won’t do better.
The LHC has a long, productive life ahead of it. An upgraded version, called the “High Luminosity LHC,” will be available in 2028.
Scientists can make substantial progress without fully understanding exactly what they’re doing.
If nature were perfectly deterministic, atoms would almost instantly all collapse. Here’s how Heisenberg uncertainty saves the atom.
Speeding through the Universe and leaving a wake of new stars, this runaway supermassive black hole is likely the first among thousands.
A new book by historian and author Paul Strathern argues that the Northern European Renaissance has long been overlooked.
You’ll be able to sleep through a war.
Philosophers and scientists spent millennia arguing about the nature of light. It turned out to be stranger than anyone imagined.
