We can reasonably say that we understand the history of the Universe within one-trillionth of a second after the Big Bang. That's not good enough.
A Fermilab study confirms decades-old measurements regarding the size and structure of protons.
All matter particles can act as waves, and massless light waves show particle-like behavior. Can gravitational waves also be particle-like?
In 1054, a core-collapse supernova occurred 6500 light-years away. In 2023, JWST imaged the remnant, and might solve a massive mystery.
With no other galaxies in its vicinity for ~100 million light-years in all directions, it's as isolated and lonely as a galaxy can be.
Gamma-ray bursts are so powerful they could vaporize the Earth from 200 light-years away. Recreating them in the lab is not easy.
Our greatest tool for exploring the world inside atoms and molecules, and specifically electron transitions, just won 2023's Nobel Prize.
Scientists may have detected the somewhat smelly chemical dimethyl sulfide on a planet 120 light-years from Earth.
A researcher explains a little-known niche within modern physics: animal collective behavior.
The best evidence for dark matter is astrophysical and indirect. Do new lensing observations point to ultra-light, wave-like dark matter?
With almost every shovel of sand shifted in Egypt, another artifact comes to light.
Explanations for the cosmic speed limit often conflate mass with inertia.
If light can't be bent by electric or magnetic fields (and it can't), then how do the Zeeman and Stark effects split atomic energy levels?
Most of us only ever see a fraction of a full rainbow: an arc. But optically, a full rainbow makes a complete circle. Physics explains why.
What do the dark recesses of the early Universe and Zelda: Tears of the Kingdom have in common? More than you could have ever hoped for.
A more distant galaxy liked the lens so much that it went and put a ring on it. Here's the science behind this remarkable cosmic object.
The intensely white coloration of the shrimp is a remarkable feat of bioengineering.
Some authors never saw their books score widespread acclaim—or even get published at all.
Here on Earth, the Sun is our primary source of light, heat, and energy. But it also poses a grave threat to human civilization.
A spherical structure nearly one billion light-years wide has been spotted in the nearby Universe, dating all the way back to the Big Bang.
