Our sun is a roiling mass of energy, with solar flares exploding on its surface, sending gas, plasma, and light that blasts across the solar system. When radiation from extra-powerful flares breaks through Earth’s outer protective magnetosphere, it can affect satellites and even electric grids and cause the aurora borealis—lighting up the night sky. Go […] On a calm day, a light breeze might barely ripple the surface of a lake on Earth. But on Saturn’s largest moon, Titan, a similar mild wind would kick up 10-foot-tall waves. This otherworldly behavior is one prediction from a new wave model developed by scientists at MIT. The model is the first to capture […] Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have discovered a close pair of quasars, which is a result of a distant massive galaxy merger. The detection of the quasar pair was detailed in a research paper published April 7 on the arXiv pre-print server. Go to Source New Curtin University-led research has used a radio telescope that spans Earth to snap images that measure the immense power of jets from black holes, confirming scientists’ theories of how black holes help shape the structure of the universe. Go to Source NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) mission has mapped interstellar ice at an unprecedented scale. Covering regions in our Milky Way galaxy more than 600 light-years across, the ice was found inside giant molecular clouds—vast regions of gas and dust where dense clumps of matter collapse […] A growing mystery in astronomy is the presence of gargantuan black holes—some weighing as much as a billion suns—existing less than a billion years after the Big Bang. According to the standard theory of black hole formation, these black holes simply should not have had enough time to grow so large. A study led by […] An international team led by Dr. Indrani Das of Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) has shown, for the first time, how infalling gas from star-forming cores gradually transitions into planet-forming disks. Their findings, combining numerical simulations with Atacama Large Millimeter/submillimeter Array (ALMA) observations, are published today in The Astrophysical Journal. Go to […] Unfortunately for science fiction fans, desert worlds outside our solar system are unlikely to host life, according to new research from the University of Washington. Scientists show that an Earth-sized planet needs at least 20 to 50% of the water in Earth’s oceans to maintain a critical natural cycle that keeps water on the surface. […] A research team has developed a new approach to detecting life beyond Earth that does not rely on identifying specific biological markers. Instead, the study suggests that life may be detectable through patterns emerging across groups of planets, offering a new framework for astrobiology in situations where traditional biosignatures are ambiguous or unreliable. Go to […] NASA and other space agencies are intent on sending astronauts back to the moon, and this time, to stay! A vital part of these plans for reducing costs and dependency on Earth is the process of In-Situ Resource Utilization (ISRU), using local resources for construction materials and meeting astronauts’ basic needs. This is why the […] Caltech researchers have identified geological features on Mars that could point to the existence of a long-dried ocean that once covered a third of the Red Planet’s surface. The research was conducted by former Caltech postdoctoral scholar Abdallah Zaki and Caltech professor of geology Michael Lamb. The study is described in a paper appearing in […] Earth and the course of life on Earth have been shaped by impacts. Scientists have uncovered links between massive impacts and changes in climate that altered the planet forever. But the further scientists look into the past to try to understand these changes, the more difficult it is to link them together. Go to Source […] For the last five years, the Dark Energy Spectroscopic Instrument (DESI) has been systematically scanning the night sky. Today marks the completion of its first map, which is the largest high-resolution 3D map of the universe ever made. Go to Source Noticeable change on Mars often takes millions of years—but the European Space Agency’s Mars Express has captured a blanket of dark ash creeping across the planet in just decades. Go to Source The lunar south pole looks chaotic from orbit. Craters heaped upon craters, ancient basins, scarps and slopes tumbling in every direction, it is without doubt, one of the most geologically complicated terrains in the inner solar system. That aside, it’s exactly where we intend to send people, since understanding what lies beneath that battered surface […] |
