“Scenes from a microworld: The eye can’t see protons, electrons, and other subatomic particles, but a camera records their frothy wakes in a chamber of liquefied neon and hydrogen at the Fermi National Accelerator Laboratory in Batavia, Illinois. Technician Karen Carew points to a straight line, possibly the track of a pion dislodged from its spot in a neon atom’s nucleus by a neutrino traveling at the speed of light.”

Fusion of deuterium with tritium creating helium-4, freeing a neutron, and releasing 17.59 MeV of energy.

Streamer chamber photo of a pion-muon-electron (pi-mu-e) decay chain resulting from an antiproton annihilation. The antiproton enters from the bottom of the picture & annihilates with a proton in neon gas filling the chamber; their energy materialises as 3 nuclear fragments (thick tracks) & several pions (less dense tracks). One positive pion curls tightly to the right in the chamber’s magnetic field before decaying to a muon; the muon forms the spiral at top before decaying to a positron…

Astronomers have discovered the largest known structure in the universe, a clump of active galactic cores that stretch 4 billion light-years from end to end. The structure is a light quasar group (LQG), a collection of extremely luminous Galactic Nulcei powered by supermassive central black holes.
