A new study led by researchers at the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC) reveals how the disks of galaxies like the Milky Way are affected by ancient galactic collisions. Go to Source Astronomers may have found an explanation for one of the biggest mysteries revealed by the James Webb Space Telescope (JWST): why so many galaxies in the early universe appear unexpectedly bright in ultraviolet light. The new study, posted to the arXiv preprint server on May 11, suggests that galaxies more than 13 billion years ago […] NASA’s Perseverance Mars rover used its Mastcam-Z camera to capture this panorama of an area nicknamed “Arbot” on April 5, 2026, the 1,882nd Martian day (sol) of the mission, during the rover’s deepest push west beyond Jezero Crater. Go to Source When it comes to space debris, what goes up is coming down more often—and not safely. Go to Source Our solar system is currently passing through the Local Interstellar Cloud, a region of highly diluted gas and dust between the stars. On its path, Earth continuously accumulates iron-60, a rare radioactive isotope of iron produced in stellar explosions. This has now been confirmed by an international research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) […] Astronomers have tracked a dramatic “changing-look” active galactic nucleus (AGN) whose central supermassive black hole appeared to switch off and then rapidly reignite. The galaxy, HE 1237−2252, dimmed in X-rays by a factor of 17 within just 18 months before recovering again. The paper outlining its analysis was uploaded to the arXiv preprint server on […] A joint European-Chinese spacecraft is set to blast off Tuesday to investigate what happens when extreme winds and giant explosions of plasma shot out from the sun slam into Earth’s magnetic shield. Go to Source Hundreds of companies raised a combined $70 billion by selling shares to the public in the United States last year. Go to Source Despite being so elusive, neutrinos are produced in abundance in some of the most violent events in the universe. One of their strangest properties is that they can spontaneously switch between three types, or “flavors”: a phenomenon known as neutrino oscillation that remains poorly understood in extreme astrophysical environments. Go to Source […] An international team of astronomers has utilized the Zwicky Transient Facility (ZTF) and the Transiting Exoplanet Survey Satellite (TESS) to investigate a binary system designated ZTF J0007+4804. As a result, they have found that ZTF J0007+4804 is the first hot subdwarf-white dwarf system discovered that produces dwarf nova outbursts. The finding is reported in a […] On Thursday, NASA issued a Request for Proposal (RFP), seeking industry collaboration for the Mars Telecommunications Network. Go to Source When NASA scientists first observed a particular radio burst from the sun in August 2025, there was nothing unusual about it. But then the radio burst kept going. Typically, solar radio bursts like these last a few hours to days. But this one was different. By the time it was over, the radio burst had […] After the success of Artemis II, longer space journeys are expected, raising new health and nutritional challenges for astronauts. Current space foods rely on dried, shelf-stable items. Go to Source Maps can show more than just where things are—they can also show how things change. New maps of artificial light reveal a planet that has been reshaping its nights through patterns of brightening and dimming. Go to Source Researchers have developed a mathematical method that enables more precise calculations of the most economical travel routes between the orbits of celestial bodies. To demonstrate this method, they calculated a more efficient path between Earth’s and the moon’s orbits than any previously described in the scientific literature. The study is published in the journal Astrodynamics. […] |
