SpaceTime with Stuart Gary Gary - Series 29 Episode 1
In this episode of SpaceTime, we delve into extraordinary cosmic phenomena and the ongoing exploration of our solar system.
Cosmic Matter Ejected at 20% the Speed of Light
Astronomers have made a groundbreaking observation of matter being ejected from a supermassive black hole at the center of the barred spiral galaxy NGC 3783, located 135 million light years away. This matter, propelled at an astonishing 20% the speed of light, challenges previously held notions about how such superluminal jets are powered. The findings suggest that a sudden change in the magnetic field, rather than radiation, may be responsible for this high-speed outburst, providing new insights into the mechanisms of black hole dynamics and their impact on galactic evolution.
Wind-Sculpted Landscapes on Mars
NASA's Perseverance Rover continues its exploration of Mars, focusing on megaripples—large sand formations shaped by wind. These megaripples, some reaching up to 2 meters in height, offer scientists a unique opportunity to study current Martian atmospheric processes. As the rover investigates the Honeyguide region, researchers hope to gain insights into the planet's wind patterns and surface chemistry, which will be crucial for future human missions to Mars.
Potential Ocean Beneath Uranus's Moon Ariel
New research suggests that Uranus's moon Ariel may harbor a vast subsurface ocean, potentially more than 170 kilometers deep. This discovery, reported in the journal Icarus, highlights Ariel's unique geological features and raises questions about its past interior structure and orbital dynamics. The study indicates that understanding Ariel's ocean could provide crucial context for the moon's surface fractures and cryovolcanic activity, emphasizing the need for future missions to the Uranian system to confirm these findings.
