SpaceTime with Stuart Gary Gary - Series 29 Episode 9
In this episode of SpaceTime, we unravel the enigma of the universe's mysterious little red dots, delve into groundbreaking insights from Jupiter regarding the evolution of our solar system's planets, and mark the commencement of construction on Earth's largest gamma-ray observatory.
The Mystery of the Little Red Dots
A fascinating new study reveals that the enigmatic little red dots observed in early images from the NASA Webb Space Telescope are, in fact, young black holes cloaked in ionized gas. Researchers from the Niels Bohr Institute's Cosmic Dawn Center have determined that these black holes, much smaller than previously thought, are in the process of consuming gas, which creates immense heat and radiation, giving them their distinctive red appearance. This discovery sheds light on the formation of some of the universe's earliest black holes just 700 million years after the Big Bang.
Jupiter's Role in Planetary Evolution
New simulations indicate that Jupiter may contain up to 50% more oxygen than the Sun, providing fresh insights into how the planets in our solar system formed. By developing a comprehensive model of Jupiter's atmosphere, researchers have resolved a long-standing debate regarding the gas giant's chemical composition. The findings suggest that Jupiter's atmosphere circulates much more slowly than previously believed, which could alter our understanding of planetary migration and formation processes.
Construction of Earth's Largest Gamma-Ray Observatory
Engineers have officially begun construction on the Cherenkov Telescope Array Observatory, set to be the largest gamma-ray telescope ever built. Located in Chile's Atacama Desert, this observatory will significantly enhance our ability to study high-energy cosmic phenomena, such as black holes and supernovae. With over 60 telescopes across two sites, the observatory will allow astronomers to observe gamma rays with unprecedented accuracy, potentially unlocking new discoveries about dark matter and the fundamental laws of physics.
