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...

Galactic gamma ray bursts predicted last year show up right on schedule

Astronomers see many periodic emissions from space, typically caused by rotation of stars and often very regular. Astrophysicists noticed a unique periodicity in the soft gamma ray emissions from a magnetar located in our galaxy. The soft gamma repeater SGR1935+2154 appears to emit bursts only within regularly spaced windows, and is inactive in between. Based on their analysis, they predicted a resumption of bursts last month; so far, a dozen have been detected.
