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

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

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.

Sunken Continents Could Unbalance Earth’s Magnetic Field

Astronomy, Astrophysics, Planetary Science /

Structures the size of continents, protruding from the lower mantle towards Earth’s outer core, may be contributing to an instability in our planet’s magnetic field. Initial Assumptions About Similarity These two formations, one beneath the Pacific and the other under Africa, have similar characteristics in terms of seismic waves, leading scientists to initially believe they

Ancient Martian Beaches Reveal Evidence of Oceans on the Red Planet

Astronomy, Planetary Science /

Mars, often depicted as a dry, dusty, and barren desert, was once abundant in water, even containing oceans, according to a recent study. Ground-Penetrating Radar Reveals Evidence of Martian Beaches Using ground-penetrating radar, researchers have discovered underground features that resemble beaches, indicating that Mars hosted a northern sea 4 billion years ago. This is some

U.S. Space Force’s X-37B Space Plane Takes a Selfie with Earth

Astronomy, Planetary Science /

Last week, the U.S. Space Force shared an image from the uncrewed X-37B space plane’s seventh mission, capturing the orbital test vehicle soaring above Earth in High Earth Orbit—a selfie worth showcasing. The 29-foot (8.8-meter) Boeing-built autonomous spacecraft reportedly used its onboard camera to take the photo while performing an aerobraking maneuver. This technique involves

SpaceX Says Starship Self-Destructed Due to Propellant Leaks, Fires, and a Comms Blackout

Astronomy, Planetary Science /

SpaceX revealed Monday that last month’s Starship explosion resulted from a chain reaction triggered by propellant leaks—a problem the company claims to have resolved ahead of a potential eighth test flight as early as Friday. The company is still awaiting FAA approval, either through the official closure of the “mishap investigation” or special authorization to
