For the first time, particle physicists have been able to precisely measure the proton’s size and structure using neutrinos with data gathered from thousands of neutrino-hydrogen scattering events collected by MINERvA, a particle physics experiment at the U.S. Department of Energy’s Fermi National Accelerator Laboratory.
The U.S. Department of Energy allocated funds to its 17 national laboratories from the Inflation Reduction Act to mitigate the rise of project costs as a result of inflation. Fermilab will spend the funding on the lab’s on-going construction projects. This will allow the lab’s major projects to uphold their schedules and keep their commitment to international collaborators.
Scientists successfully used a new technique to cool a particle beam and make it denser. The new method may enable future experiments to create more particle collisions. Denser particle beams provide researchers a better chance of exploring rare physics phenomena that help us understand our universe.
Astronomers have unveiled the first image of the supermassive black hole at the center of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the center of most galaxies.
