Historic First: Non-Professional Astronauts Complete Spacewalk on SpaceX's Polaris Dawn Mission The mission, funded by billionaire Jared Isaacman, aimed to test new technologies for future space exploration. Alongside Isaacman, the crew included retired U.S. Air Force Lt. Col. Scott Poteet and two SpaceX employees.
Scientists Discover 'Smiley Face' Crater on Mars, Offering Clues to Ancient Life Chloride salts, left behind as Mars’ lakes evaporated, are crucial for understanding the Martian climate and could be key to detecting preserved signs of ancient microbial life.
Scientists Confirm Earth Was Once a Giant Snowball, Triggering Evolutionary Boom By examining the decay of uranium into lead within the zircons, they accurately dated the rocks to the Sturtian glaciation period, when Earth's climate underwent drastic changes.
Cassini Discovers Ripples and Unique Methane-Ethane Composition in Titan’s Seas While the ripples in these seas were small—reaching heights of 3.3 mm in open waters and 3.6-5.2 mm near coastal areas—the findings provide valuable clues about Titan's dynamic weather systems and liquid interactions.
Scientists Discover Donut-Shaped Structure Inside Earth's Core Researchers believe that this discovery will help them better understand how the magnetic field changes over time and its implications for planetary habitability, even on other celestial bodies.
NASA's Perseverance Rover Begins Ambitious Climb to Crater Rim on Mars The rover will climb 305 meters (1,000 feet) to reach the crater's rim, an area believed to have once harbored hydrothermal vents—locations that on Earth are linked to the origins of life.
NASA Successfully Deploys Its Advanced Composite Solar Sail System In the coming weeks, NASA will test the spacecraft's ability to maneuver using only the pressure of sunlight on the sail. These tests will help determine the effectiveness of the solar sail for future missions.
Scientists Unveil the Mysterious Source of the Moon's Atmosphere The findings indicate that impact vaporization from micrometeorites is the dominant process sustaining the Moon's atmosphere, accounting for about 70% of its formation.
India’s Lunar Rover Uncovers Evidence of Moon’s Molten Past This new data gives further credence to the idea that the Moon was once a hot, molten body following its formation, likely caused by a colossal impact between Earth and a Mars-sized protoplanet.
Astrophotographers Capture Rare Alignment of Jupiter and Mars in the Night Sky The two planets, which last appeared this close together over two years ago, dazzled skywatchers in the early morning hours, with a spectacle that won’t be seen again until 2033.
Astronomers Discover a Brown Dwarf Escaping the Milky Way The object, named CWISE J1249, is racing through space at an astonishing speed of more than 1 million kilometers per hour, marking the first time such a phenomenon has been observed.
NASA Scientists Discover Massive Underground Water Reservoirs on Mars The findings suggest that while the surface of Mars remains a barren desert, much of the water that once flowed in rivers and lakes millions of years ago has seeped into the planet's crust, where it has been preserved.
Scientists Unveil New Clue in Solving Jupiter's Great Red Spot Mystery The Great Red Spot is slowly diminishing in size, from 39,000 kilometers across in the 19th century to just 14,000 kilometers today. By comparison, Earth measures 12,742 kilometers in diameter.
Scientists Discover Earth-Sized Planet in Habitable Zone, Raising Hopes for Extraterrestrial Life The amount of starlight it receives falls between the levels Earth and Venus experience, making it a prime candidate for further study on the factors that determine planetary habitability.
Ancient Martian Lake Larger Than Any on Earth Photographed by Mars Express The lake, which existed around 3.7 billion years ago, covered an area of approximately 1.1 million square kilometers, or about the size of Egypt, and held enough water to fill the Caspian Sea three times over.
