NASA's Parker Solar Probe executed a short maneuver on Aug. 26 that kept the spacecraft on course for the mission's seventh and final planned Venus flyby on Nov. 6. Operating on preprogrammed commands, Parker fired its small directional thrusters for about 17 seconds, changing its velocity by less than a mile per hour, and setting its trajectory some 386 miles (593 kilometers) closer to a

Like two Sumo wrestlers squaring off, the closest confirmed pair of supermassive black holes have been observed in tight proximity. These are located approximately 300 light-years apart and were detected using NASA's Hubble Space Telescope and the Chandra X-ray Observatory. These black holes, buried deep within a pair of colliding galaxies, are fueled by infalling gas and dust, causing them to s

The mystery of how supermassive black holes, which can be millions of times more massive than the sun and sit at the heart of most galaxies, came to exist is one of the great questions in astrophysics. Researchers from the Nevada Center for Astrophysics at UNLV (NCfA) have uncovered new evidence that the supermassive black hole at the center of the Milky Way, called Sagittarius A' (Sgr A')

In a new study, astronomers report novel evidence regarding the limits of planet formation, finding that after a certain point, planets larger than Earth have difficulty forming near low-metallicity stars. Using the sun as a baseline, astronomers can measure when a star formed by determining its metallicity, or the level of heavy elements present within it. Metal-rich stars or nebulas form

Using a Google AI tool, scientists have revealed how proteins in a heat-loving microbe respond to intense pressure, similar to conditions found in the planet's deepest ocean trenches. This research offers key insights into how life's building blocks may have evolved under early Earth conditions and opens new doors for future studies. The research, now published in 'PRX Life', highlights th

Many imagine the solar system's edge is marked by Neptune, the furthest known planet. However, astrophysicist Susanne Pfalzner from Forschungszentrum Julich notes, "Several thousand celestial bodies are known to move beyond the orbit of Neptune." It is estimated that tens of thousands of objects larger than 100 kilometers exist in this region. "Surprisingly, many of these so-called trans-Neptuni

European Space Agency (ESA) engineers are advancing the capabilities of autonomous Mars rovers, as demonstrated in recent trials conducted in a UK quarry. The ExoMars Rosalind Franklin rover, nicknamed "Codi," showcased its ability to locate and retrieve sample tubes using its robotic arm and sophisticated computer vision system. Codi drove to the sample locations with a remarkable accurac

As part of the Artemis lunar exploration campaign, NASA aims to deepen its understanding of the moon's surface and prepare for future Mars missions. The Artemis missions will target the lunar south pole, a region that holds scientific interest due to its permanently shadowed areas, which may contain water ice reserves vital for sustaining human exploration. This will be NASA's first crewed moon

The ChemCam instrument, developed by Los Alamos National Laboratory, has fired its laser for the 1 millionth time on Mars. Positioned atop NASA's Curiosity rover, ChemCam has been key to scientific discoveries since its deployment in 2012. "Not only is this a remarkable technical accomplishment for our instrument, but it also represents a staggering amount of chemistry data from the surfac

ESA's Metal 3D Printer has successfully produced the first-ever metal part in space. This technological milestone, achieved through a partnership with Airbus, marks a significant advancement in additive manufacturing in microgravity. The Metal 3D Printer was launched to the International Space Station (ISS) earlier this year. ESA astronaut Andreas Mogensen was responsible for installing th
