In this episode of SpaceTime, we uncover remarkable revelations about Jupiter, lightning-induced gamma rays, and groundbreaking achievements in spaceflight.
Jupiter's Magnificent PastA new study reveals that Jupiter, the solar system's largest planet, was once twice its current size and possessed a magnetic field 50 times stronger than today. Researchers, led by Konstantin Batygin, used the orbits of Jupiter's small moons, Amalthea and Thebe, to deduce these findings, providing critical insights into the early stages of planetary formation. The implications of this research could reshape our understanding of gas giants and their formation processes across the universe.
Gamma Rays and LightningIn a groundbreaking discovery, scientists have detected intense flashes of gamma rays produced by lightning strikes. This phenomenon, known as terrestrial gamma ray flashes, occurs when lightning accelerates electrons to near light speeds, resulting in bursts of radiation. The study, published in Science Advances, sheds light on the high-energy processes occurring in Earth's atmosphere, enhancing our understanding of lightning's power and its effects on our planet.
Precision Formation Flying in SpaceHistory has been made in Earth orbit as two spacecraft from the European Space Agency's Proba 3 mission successfully flew in millimeter-perfect formation for the first time. This precision alignment is crucial for studying the Sun's corona, allowing the two satellites to simulate a single large spacecraft. We discuss the technology behind this mission and its potential to revolutionize solar observations.
