electrons

This photo shows instances of the black aurora, the dark patches that sometimes form within an aurora where electrons escape upward. The photo was taken near Thompson, Manitoba, Canada, on Sept. 29, 2024, at 3:19 a.m. CDT. The photographer, Donna Lach, submitted this image to NASA’s Aurorasaurus citizen science project, which works with participants around the world to photograph, report and verify aurora sightings to advance auroral science.

Electrons are made up of a negative electrical charge, and scientists at JILA have been trying to measure how evenly that charge is spread between the north and south pole of the electron. Any unevenness would indicate that the electron is not perfectly round, and that would be evidence of an asymmetry in the early universe that led to the existence of matter. The Cornell Group at JILA studied how the electrons in molecules behaved as they adjusted the magnetic field around them to look for any shift in the electrons. Credit: JILA/Steven Burrows
