The muon particle infographic fermilab
From unexplained tracks in a balloon-borne experiment to cosmic rays on Earth, the unstable muon was particle physics' biggest surprise.
JuMBOs planet mass orion nebula JWST nircam
In the largest star-forming region close to Earth, JWST found hundreds of planetary-mass objects. How do these free-floating planets form?
particle collision
2023's Nobel Prize was awarded for studying physics on tiny, attosecond-level timescales. Too bad that particle physics happens even faster.
FIRE simulation JWST starburst star-forming
With so many early galaxies of unexpectedly large brightnesses, JWST surprised us all. Here's how scientists made sense of what we see.
hydrothermal field
With such a vast Universe and raw ingredients that seem to be everywhere, could it really be possible that humanity is truly alone?
An image of a pink spiral on a black background depicting uncertainty.
If nature were perfectly deterministic, atoms would almost instantly all collapse. Here's how Heisenberg uncertainty saves the atom.
attosecond spectroscopy research center laser
Our greatest tool for exploring the world inside atoms and molecules, and specifically electron transitions, just won 2023's Nobel Prize.
