Since astronomers discovered the Smith Cloud, a giant gas cloud plummeting toward the Milky Way, they have been unable to determine its composition, which would hold clues as to its origin. University of Notre Dame astrophysicist Nicolas Lehner and his collaborators have now determined that the cloud contains elements similar to our sun, which means the cloud originated in the Milky Way’s outer edges and not in intergalactic space as some have speculated.

Image from CERN of the CMS detector illustrates one of the proton collisions that may have produced a mysterious particle

Physicists around the world were puzzled recently when an unusual bump appeared in the signal of the Large Hadron Collider, the world’s largest and most powerful particle accelerator, causing them to wonder if it was a new particle previously unknown, or perhaps even two new particles. The collision cannot be explained by the Standard Model, the theoretical foundation of particle physics.
