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...

Stardust machine shows presence of carbon nanograins, molecular compounds but few aromatics

A team of researchers affiliated with several institutions in Spain and one in France has built what they call their Stardust machine—a device that mimics the activity around a red giant where real stardust forms. In their paper published in the journal Nature Astronomy, the group describes their new machine and what it showed them about the means by which stardust forms naturally. Michael Gatchell, with Stockholm University, has published a News & Views piece discussing the work in the same journal issue.
