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...

The very first structures in the Universe

The first moments of the Universe can be reconstructed mathematically even though they cannot be observed directly. Physicists have greatly improved the ability of complex computer simulations to describe this moment, discovering that a complex network of structures can form in the first trillionth of a second after the Big Bang. These microscopic clumps have masses of only a few grams and fit into volumes much smaller than particles.
