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...

IRAS 18379–1707 is a metal-poor high-velocity star, observations find

Astronomers have conducted high-resolution spectroscopic observations of IRAS 18379–1707 (or LS 5112), a candidate post-asymptotic giant branch (post-AGB) star in the Milky Way galaxy. Results of the observations provide more details about the properties of this object, revealing that it is a metal-poor, high-velocity star. The findings are detailed in a paper published November 28 on arXiv.org.
