When you look up at the sky on a sunny day, the sun might seem like a bright spot, unchanging in the sky. But the sun is a complex, dynamic celestial body, wrapped in electrical currents and magnetic fields that constantly move and tangle as it rotates. At times the sun’s surface is very active, […] At the center of most large galaxies sits a supermassive black hole (SMBH). When these black holes are actively consuming material, they become incredibly luminous quasars. But some quasars appear wrapped in thick clouds of dust, making them hard to detect. In a new study, astronomers have revealed 77 new, hidden, “heavily reddened” quasars (HRQs). […] The science academies of G7 member countries have identified international space governance as a pressing issue for the G7 Leaders’ Summit, to be held from June 15–17 in Evian, France. Go to Source A team of U.S. astronomers has observed a binary pair of white dwarfs where one star is actively devouring material from the other. Led by Emma Chickles at MIT, the researchers revealed one of the clearest views yet of how ultracompact white dwarf binaries exchange mass at extreme orbital periods—offering an enticing potential target for […] SpaceX launched its biggest, most powerful Starship yet on a test flight Friday, an upgraded version that NASA is counting on to land astronauts on the moon. Go to Source A Hong Kong astronaut will join a Chinese space mission for the first time as part of a three-person crew launching on Sunday, as Beijing edges closer to its goal of landing people on the moon. Go to Source When the solar system formed, a disk of gas and dust orbited the young sun. Over the course of millions of years, the dust gradually clumped together to form kilometer-sized chunks known as planetesimals. Some grew into planets, while the rest are considered to be the precursors of today’s asteroids. Researchers assume that this development […] Elon Musk’s SpaceX will attempt another launch of its mammoth Starship rocket Friday, after the previous evening’s try was called off over technical issues. Go to Source Researchers at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, have identified a promising new method for measuring the mass of galaxies orbiting the Milky Way by using pulsars, some of the universe’s most precise natural clocks, to detect tiny gravitational effects across our galaxy. Go to Source […] Astronomers from Italy and Brazil have investigated a nearby red dwarf star known as Ross 318 and have discovered an exoplanet orbiting this star, which is at least six times more massive than Earth. The discovery is reported in a research paper published May 11 on the arXiv preprint server. Go to Source […] The liquid iron in Earth’s outer core doesn’t always behave as expected. When it changed direction in an unexplained way, ESA satellites provided data on the direction of flow, helping scientists gain better insight into the dynamics at the center of our planet. Go to Source Look closely at this image from NASA’s Hubble Space Telescope and you’ll see galaxies of various shapes and sizes clustered together toward the center-left of the image. A few foreground stars shine brightly and are easily distinguished by the spikes that appear to extend outward from each star. These spikes, called diffraction spikes, are the […] Elon Musk’s SpaceX postponed the highly anticipated launch of its upgraded Starship megarocket, calling off Thursday’s test after multiple countdown stops-and-starts. Go to Source On May 21, ground controllers powered down NASA’s AWE (Atmospheric Waves Experiment) instrument, bringing the data collection phase of the mission to a successful and scheduled end, surpassing its planned two-year mission. Go to Source The 8.1-meter Gemini North telescope, located on the summit of Maunakea in Hawai’i, has captured NGC 1514, nicknamed the Crystal Ball Nebula, in awe-inspiring detail. This nebula, with its mesmerizing glow of gas, harbors hints of a past stellar death, and its asymmetrical shell is now being shaped by the pair of binary stars that […] |
