Astronomers Finally Locate the Missing Half of the Universe’s Visible Matter

Astronomy, Planetary Science, Science /

A new sky survey has revealed the long-sought whereabouts of half of the Universe’s visible matter—solving a mystery that had puzzled scientists for decades. The Hidden Clouds Around Galaxies This elusive matter turns out to be vast, invisible clouds of ionized hydrogen surrounding galaxies. Although these clouds usually go undetected, an international team of astronomers […]

Origins of Earth’s Water May Not Be as Complicated as We Thought

Environmental Science, Planetary Science /

Planetary scientists have long believed that Earth’s water came from external sources, such as hydrogen-rich rocks and comets, which arrived after the planet formed, given the apparent lack of moisture in the early building blocks of Earth. New Research Challenges the Conventional Theory However, a recent study by researchers from the University of Oxford and

Strongest Evidence of Alien Life Yet Identified Found 124 Light-Years From Earth

Astronomy, Planetary Science /

Astronomers announced last Thursday the detection of the most promising signs yet of possible life on a planet outside our Solar System — though some in the scientific community responded with caution. The planet in question is K2-18b, located 124 light-years away in the constellation Leo. For some time now, researchers have debated whether it

Scientists Uncover New Evidence that Questions Existing Theories About How Water First Appeared on Earth

Astronomy, Planetary Science /

Researchers at the University of Oxford have uncovered compelling evidence about the origins of Earth’s water. By analyzing a rare meteorite type known as an enstatite chondrite—chemically similar to the early Earth—they discovered a native source of hydrogen, a key ingredient in water formation. Discovery of native hydrogen in ancient meteorite suggests early Earth materials

Why Rare Meteorites Could Unlock Secrets of the Early Solar System

Astronomy /

Carbonaceous chondrites—a rare type of meteorite—hold clues to the early days of the solar system. These ancient space rocks are packed with water, carbon, and organic compounds, making them incredibly valuable to scientists. However, despite their importance, they make up less than 4% of meteorites found on Earth. So, where are the rest? A new

We Were Wrong About Uranus: New Study Solves Long-Standing Mysteries

Astronomy, Planetary Science, Science /

Recent observations have corrected a long-held misconception regarding the length of a day on Uranus. New, more accurate measurements of the planet’s rotation have revealed that a full day on Uranus lasts 17 hours, 14 minutes, and 52 seconds. This is 28 seconds longer than previously estimated, based on data gathered by Voyager 2 during

Mudball Meteorite Spent 2 Million Years Dodging Collisions – Until Eart

Astronomy, Stellar Astronomy /

One of the most extensively studied space rocks has recently surprised scientists once again. The “mudball meteorite” Aguas Zarcas, which spent two million years in orbit without colliding with any other objects (or sustaining any damage if it did), challenges the conventional view of the “fragile” carbonaceous chondrite class to which it belongs. Public Fascination

Musk’s Starlink Set to Debut in India Via Airtel

Astronomy, Planetary Science /

Airtel announced on Tuesday a partnership with SpaceX to bring Starlink’s high-speed satellite internet to India, years after Elon Musk’s company first attempted to enter the world’s second-largest internet market. However, this is not a confirmed rollout. The launch depends on regulatory approval from IN-SPACe and the Department of Telecommunications, Airtel clarified in its statement.
