Scientists have discovered incredibly powerful cosmic accelerators, dubbed PeVatrons, within our Milky Way galaxy. These sources are responsible for the highest-energy cosmic rays ever detected, some reaching energies of 10 peta-electron-volts. The discovery, driven by observatories like LHAASO, is revolutionizing our understanding of our galaxy's violent and energetic nature.
Earth's atmosphere may face a new threat from the growing number of satellites burning up upon re-entry. Scientists warn that the resulting particles could deplete the ozone layer and impact climate, urging for greater research and regulation.
Explore stunning images expected from Titan's Dragonfly mission, the challenges of spotting Artemis 2 with telescopes, and the fascinating science behind moons having moons. Discover the future of lunar navigation and the final stages of stars.
Discover the Casimir effect, a quantum phenomenon where 'empty' space exerts a powerful force. Tiny quantum waves, blocked in the gap between close mirrors, create a pressure that pushes them together, revealing the dynamic nature of the vacuum.
Thousands of newly identified scarps on the Moon reveal that its interior is actively cooling and shrinking, causing the lunar crust to fracture. This ongoing geological activity, driven by global contraction, results in these massive cliff-like features and suggests the Moon is more geologically active than previously thought.
NASA's Juno mission has revealed that Jupiter's core is "fuzzy," challenging theories of planetary formation. The probe also captured stunning images of polar cyclones, analyzed atmospheric composition, and provided new insights into Jupiter's powerful magnetic field and auroras.
The ambitious LUVOIR telescope concept, designed to search for life on exoplanets, is currently in a state of uncertainty. While not actively in development, its goals continue to drive future space observatory designs and the ongoing quest to find life beyond Earth.
Actor Ryan Gosling and an astrophysicist discuss the real science behind 'Project Hail Mary.' They explore concepts like time dilation, the speed of light, and the search for extraterrestrial life, highlighting the film's commitment to scientific accuracy.
The movie Project Hail Mary dives deep into real astrophysics and biology. It explores concepts like solar dimming, relativity, and alien life. While much is fiction, the film grounds its narrative in actual scientific principles, sparking curiosity about the universe.
SpaceX successfully conducted a crucial engine test fire of its Super Heavy booster on the new Pad 2, igniting 10 Raptor engines. This marks a significant step towards Starship's full-scale testing and future missions. The report also touches on potential shifts in NASA's Artemis plans and the continued expansion of Starlink.
