Multi-messenger astronomy combines observations from gravitational waves, electromagnetic waves, cosmic rays, and neutrinos to study phenomena from neutron stars to the large-scale structure of the Universe. This approach enables breakthroughs in understanding extreme matter conditions and fundamental cosmological questions.

Why it matters: It reveals extreme matter properties and cosmic expansion, addressing mysteries like dark matter and dark energy.

The big picture: Multi-messenger data spans scales from neutron stars’ interiors to cosmological distances and epochs.

Stunning stat: Multi-messenger observations uniquely probe physical processes inaccessible by single-messenger methods.

The stakes: Without multi-messenger synergy, key insights into nuclear physics and cosmology could remain undiscovered.
