University of Birmingham experts have created open-source computer software that helps scientists understand how fast-moving particles behave when they interact with electromagnetic waves in space. Understanding how these particles behave in Earth’s radiation belts is crucial because high-energy electrons can damage satellites, while radiation belt dynamics affect space weather forecasts. Better models help protect astronauts, […] On a chilly yet beautifully clear evening last November, I sat on a video call with colleagues and happened to mention the live feed from the International Space Station—a real-time broadcast from onboard cameras as the station orbits Earth. Go to Source Do aliens exist? Could Earth really be the only planet hosting intelligent life? Go to Source Max Planck Institute for Extraterrestrial Physics scientists have been able to disentangle the X-ray glow originating in our solar system from similar emission reaching us from deep space, using data from the SRG/eROSITA space telescope. Four sky maps obtained between 2019 and 2021 from a vantage point approximately 1.5 million km from Earth—approximately four times […] Astronomers using the W. M. Keck Observatory on Maunakea, Hawaiʻi Island are revealing new insight into the composition and origins of Uranus’s two outer rings. Using data from the Keck Observatory Archive (KOA), combined with observations taken by the Hubble Space Telescope (HST) and the James Webb Space Telescope (JWST), researchers constructed the first complete […] It is tempting to view the Artemis II splashdown as the exclamation point on a successful lunar mission. And from launch to completion, it was indeed a textbook voyage of discovery for four astronauts, shared with enthralled millions watching across the globe. Go to Source 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.
