Billions of years ago, Earth was a harsh environment, frequently bombarded by meteorites. One of the most significant impacts occurred 3.26 billion years ago, when a meteorite the size of four Mount Everests collided with the planet. This event, known as the "S2" impact, left geological evidence in the Barberton Greenstone Belt in South Africa and is the focus of new research that sheds light on A new view of the in-between years of our Universe

Just like we use photos to reflect on memories of our past, astrophysicists want to use images of far-off galaxies to understand what the universe was like in its juvenile years. But current imaging technology can only reach so far back in history - 90 to 95 percent of the volume of our 14-billion-year-old universe remains unseen.

A collaborative effort between Southwest Research Institute (SwRI) and NASA's Jet Propulsion Laboratory (JPL) seeks to explain mysterious surface features observed on airless celestial bodies, such as the asteroids Vesta and Ceres, and Jupiter's moon Europa. These bodies, recently explored by NASA's Dawn mission and soon by the Europa Clipper mission, exhibit flow patterns that may result from l Betelgeuse may have an orbiting companion star

Betelgeuse, the tenth-brightest star in the night sky, may not be on the verge of a supernova explosion, as previously thought. A new study indicates that the star's fluctuating brightness is likely due to an unseen companion star orbiting Betelgeuse.
Referred to as Alpha Ori B, or the "Betelbuddy," by astrophysicist Jared Goldberg, this companion star might influence Betelgeuse's brightne Gemini North reveals Perseus Cluster galaxies linked by dark matter

A century after Edwin Hubble's pivotal discovery of galaxies beyond the Milky Way, the Gemini North telescope has captured a mesmerizing image of the Perseus Cluster, one of the largest galaxy clusters known. This detailed image, taken by the International Gemini Observatory, highlights the individual galaxies within the cluster, shedding light on their characteristics and the cosmic puzzle of d Harnessing AI to improve space weather forecasting with NSF's GONG Data

Solar filaments, the dramatic thread-like structures visible in the Sun's chromosphere, may hold crucial insights into one of the most significant space weather phenomena: Coronal Mass Ejections (CMEs). These immense bursts of plasma and magnetic fields from the Sun can eject billions of tons of material into space. When CMEs reach Earth's magnetosphere, they have the potential to trigger geomag Trading NFTs as a New Investment Strategy
