  • Something Inside the Earth is "Stretching" the Length of a Day

    Something Inside the Earth is "Stretching" the Length of a Day
    2024/12/25
    The length of a day on Earth is not constant. Hidden "forces" within the planet are subtly stretching or shortening the duration of a day in various cycles, revealing unresolved mysteries about Earth's internal geodynamics.A new study from the Swiss Federal Institute of Technology (ETH Zürich) has uncovered a mysterious cycle affecting the length of a day. According to Science Alert, scientists have long known that a day is not precisely 24 hours. Instead, it fluctuates due to three primary factors.First, on a century scale, the duration of a day changes by approximately 1.72 milliseconds per 100 years. This is caused by the gradual expansion of Earth’s crust as ancient ice sheets melt, combined with the gravitational effects of the Moon.

  • NASA/ESA Monitors "Cosmic Eye" Staring at Earth

    NASA/ESA Monitors "Cosmic Eye" Staring at Earth
    2024/12/25
    NASA has unveiled a mesmerizing image captured by the Hubble Space Telescope, showing a structure dubbed the "Cosmic Eye," officially named NGC 2566. This spiral galaxy appears to gaze intently at Earth from the depths of space, though its striking appearance is purely coincidental.NGC 2566, a spiral galaxy with its plane tilted at an angle to our line of sight, creates an almond-shaped silhouette in photographs, reminiscent of an eye. According to NASA, Hubble’s observations provide an extraordinary view of this galactic structure, allowing astronomers to study its star clusters and star-forming regions.

  • World's Largest Neutrino Detector in China Nears Operation

    World's Largest Neutrino Detector in China Nears Operation
    2024/12/25
    China’s Jiangmen Underground Neutrino Observatory (JUNO), located in Guangdong province, has entered a crucial phase as it begins the process of filling its massive detector with ultra-pure water. This step marks the final milestone before the facility officially starts collecting scientific data on neutrinos—commonly referred to as "ghost particles"—in August next year.The ultra-pure water, which undergoes meticulous filtration through advanced systems, began flowing into JUNO’s detector on December 18 at a rate of 100 tons per hour. The project is managed by the Institute of High Energy Physics (IHEP) under the Chinese Academy of Sciences and is poised to contribute significant advancements to the field of particle physics.At the core of JUNO lies a colossal spherical detector designed to measure neutrinos produced by two nuclear power plants located nearby. This detector, buried 700 meters underground, will contain 20,000 tons of liquid scintillator—a sensitive medium that emits light when neutrinos interact with it. The liquid scintillator will be suspended within an outer shield of 35,000 tons of ultra-pure water, which serves to block external radiation and other interference.
