'Planet Y' theory hints at hidden Earth-size world lurking in the solar system — and it could be much closer to us than 'Planet Nine'

A new study raises concerns about the increasing congestion in low Earth orbit, where hundreds of satellites are expected to operate in already crowded regions. This situation poses significant risks for safe and sustainable space operations, highlighting the urgent need for better management and regulation of orbital traffic to prevent potential collisions and ensure the long-term viability of satellite missions.

A recent study highlights a concerning trend: adolescents who frequently use social media tend to score lower on reading and memory tests. This finding is significant as it raises questions about the impact of digital engagement on cognitive development during crucial formative years. As social media becomes increasingly integrated into daily life, understanding its effects on young minds is essential for parents, educators, and policymakers.

A recent study suggests that the asteroid Psyche, valued at an astonishing $100,000 quadrillion, may have experienced eruptions of molten iron and nickel, similar to metal volcanoes. This finding is significant as it could reshape our understanding of the asteroid's composition and origins, particularly if it shares chemical similarities with metal-rich meteorites. Such insights not only enhance our knowledge of celestial bodies but also fuel interest in space exploration and the potential resources they may hold.

Scientists are exploring the ages of planets in our solar system to understand their formation. By using various dating methods, they aim to identify which planets are the youngest and oldest. This research is crucial as it helps us learn more about the history of our solar system and the processes that shaped it.

This week in science news, astronomers are making strides in uncovering the origins of comet 3I/ATLAS, while a peculiar gravity anomaly has been detected off the coast of Africa. Additionally, researchers are exploring the potential of AI to design entirely new viruses. These developments are significant as they enhance our understanding of celestial bodies, challenge our knowledge of Earth's gravitational forces, and push the boundaries of biotechnology.

A groundbreaking study suggests that planets orbiting white dwarf stars, previously thought too hot to support alien life, might actually be habitable. By incorporating Einstein's general relativity into their research, scientists are challenging long-held beliefs about planetary habitability. This discovery could open new avenues in the search for extraterrestrial life, making it an exciting development in astrobiology.

The Taurid meteor shower of 2025 has kicked off, and it's expected to produce some spectacular fireballs in the coming weeks. This annual event is known for its stunning displays, making it a highlight for stargazers and astronomy enthusiasts alike. The excitement around the Taurids lies in their potential to create dramatic visual phenomena in the night sky, drawing attention to the wonders of our universe.

Scientists are making significant strides in understanding how asteroids spin in space, which is crucial for developing methods to deflect them. This research could potentially save Earth from catastrophic impacts in the future, highlighting the importance of space science in protecting our planet.

'Star Trek: Strange New Worlds' is back with an exciting glimpse into Season 4, where Captain Pike and the crew of the Enterprise face new cosmic challenges. The clip reveals that while the Vezda threat has been dealt with, the universe still holds many surprises for our heroes. This matters because it keeps the beloved franchise alive and introduces fresh narratives that fans can look forward to in 2026.

Recent research has revealed that a puzzling platinum signature found beneath Greenland's ice sheet likely comes from a volcanic fissure eruption in Iceland rather than a meteorite impact. This discovery is significant as it not only clarifies the origin of this unusual platinum presence but also enhances our understanding of geological processes in the region, potentially impacting climate studies and our knowledge of volcanic activity.

The World Health Organization has issued a stark warning about a significant rise in drug-resistant infections, highlighting a growing public health crisis. This increase poses serious risks to healthcare systems worldwide, as common infections become harder to treat, leading to longer hospital stays and higher mortality rates. The WHO's alert emphasizes the urgent need for improved antibiotic stewardship and innovative treatments to combat this alarming trend.
