Astronomers using NASA’s James Webb Space Telescope have discovered a giant planet outside our solar system, called an exoplanet, hiding within one of the most intensely studied planetary systems in the Milky Way galaxy. Go to Source Before Artemis astronauts land on the moon’s surface in 2028, NASA will conduct the Artemis III demonstration mission in 2027, allowing teams on Earth and in orbit to practice rendezvous and docking operations between commercial human landing systems and the Orion spacecraft. Data from that mission, along with future uncrewed demonstration missions at the moon, […] Despite their depiction as massive monsters that simply suck in everything, including light, astronomers know black holes actually spin. And they spin really, really quickly. Determining just how quickly is key to understanding how they affect their immediate vicinity and the galaxies that surround them. A new paper by Tegan Thomas of the University of […] Peak star formation took place during cosmic noon, between 2–3 billion years after the Big Bang. The star formation rate (SFR) back then was up to 100 times greater than it is today. For the SFR to be so high, gas had to move through galaxies efficiently. Go to Source What does it take to catch up with a small, tumbling rock hundreds of thousands of kilometers from Earth? For China’s Tianwen-2 mission, the answer was a 400-day chase covering roughly 1 billion kilometers (621 million miles) of deep space—one that has just ended in success. The China National Space Administration has confirmed that the […] Scientists have painted the most detailed portrait yet of the planetary system orbiting Barnard’s Star—the sun’s closest neighbor after Alpha Centauri, just under six light-years from Earth. Go to Source The UK Space Agency and space startup Vast just signed an agreement to send Paralympic sprinter and below-knee amputee John McFall into orbit as early as 2027. Most coverage framed it as a victory for inclusion. As a space health researcher, I think something far more interesting happened. Go to Source A Southwest Research Institute-led study has proposed a connection between a specific collision in the main asteroid belt and an inner-solar-system-wide bombardment episode that may have had measurable biological and geological consequences on Earth. The research suggests that the catastrophic breakup of the Eulalia parent body could be linked to an impact shower that struck […] NASA’s Perseverance Mars rover has uncovered evidence that a 245-foot-thick (75-meter-thick) stack of ancient rock on the rim of Jezero Crater was built by repeated asteroid impacts. Referred to as the “Broom Point member” by the rover’s science team, this sequence of layered bedrock is likely more than 3.9 billion years old, making it among […] On July 16, 2024, a daytime meteor shook New York City with a sonic boom as it passed just south of the Statue of Liberty. Now, an international team of researchers reports in the journal Science Advances that a short time later, a meteorite weighing more than 2 pounds crashed through the roof of a […] Typically, astronomers identify comets by their distinct atmospheres, or comae, and their tails, which are created as the sun vaporizes a comet’s ice. These features emit a glow when sunlight bounces off dust and water droplets. As gas escapes the body of the comet, it also acts as a tiny thruster, subtly changing the comet’s […] The European Space Agency’s Mars Express has spotted a swath of metallic-looking waves filling Mars’s large Kaiser Crater—an ancient and otherworldly dune field sculpted by wind. Go to Source The effects of extreme space weather may be larger than previously thought, research in the journal Nature reveals. The paper, titled “Regression to the mean can explain saturation of geomagnetic storms,” is led by Dr. Nithin Sivadas of NASA’s Goddard Space Flight Center and co-authored by Dr. Maria Walach from Lancaster University. Go to Source […] European astronomers have conducted optical and radio observations of an enigmatic radio source designated GRS 0917+75. As a result, they found that GRS 0917+75 is a giant radio galaxy and determined its properties. The new findings were published July 3 on the preprint server arXiv. Go to Source A team of astronomers has discovered a third planet orbiting the star Beta Pictoris. The new planet, Beta Pictoris d, is 100 times fainter than Beta Pictoris b—the first planet discovered in the same system—and is among the lightest exoplanets ever imaged from the ground. After spotting the planet using the European Southern Observatory’s Very […] |
