NASA's Lucy probe is set to fly on April 20, 2025

NASA's Lucy probe is scheduled to make a significant flyby of the asteroid Donaldjohanson on Easter Sunday, April 20, 2025. Here are some detailed aspects of this mission: Mission Objectives: The Lucy mission aims to study the Trojan asteroids, which are believed to be remnants from the early solar system. By examining these asteroids, scientists hope to gain insights into the formation and evolution of the solar system. Asteroid Donaldjohanson: Named after paleontologist Donald Johanson, who discovered the famous Australopithecus fossil "Lucy," this asteroid orbits the Sun in a region known as the L4 Trojan camp, situated ahead of Jupiter in its orbit. It is one of the many Trojan asteroids that are thought to contain primitive materials. Flyby Details: During the flyby, Lucy will use its suite of scientific instruments to gather data about Donaldjohanson's surface composition, geology, and morphology. The close encounter will allow for high-resolution im...

Unprecedented look at electron: Size limit for undiscovered subatomic particles determined

A new study suggests that many theorized heavy particles, if they exist at all, do not have the properties needed to explain the predominance of matter over antimatter in the universe. If confirmed, the findings would force significant revisions to several prominent theories posed as alternatives to the Standard Model of particle physics, which was developed in the early 1970s.
