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 Sun is less active magnetically than other stars

Our sun is the source of life on Earth. Its calm glow across billions of years has allowed life to evolve and flourish. This does not mean the sun doesn't have an active side. We have observed massive solar flares, such as the 1859 Carrington event, which produced northern lights as far south as the Caribbean, and drove electrical currents in telegraph lines. If such a flare occurred in Earth's direction today, it would devastate our electrical infrastructure. But fortunately for us, the sun is mostly calm—unusually calm when compared to other stars.
