Black Hole Merger Supports Hawking's Theorem
Astronomers announced on September 17, 2025, the detection of a black hole merger that provides strong evidence for Stephen Hawking's area theorem. Observed via gravitational waves, the event aligns with predictions that black hole surface areas cannot decrease. This bolsters fundamental physics theories amid ongoing cosmic explorations.
NASA Partners with Startup to Extend Space Telescope's Life
Facing the imminent decommissioning of an aging space observatory, NASA has enlisted a private startup to perform a daring orbital maneuver, pushing the telescope farther into space to prolong its scientific mission. The initiative, announced on September 24, 2025, involves innovative propulsion technology and highlights the growing role of commercial entities in space exploration. This move could extend the telescope's operations by several years, allowing continued astronomical observations.
General relativity may preserve habitable planets around white dwarfs
A new study suggests that Einstein's general relativity could prevent tidal heating from destabilizing rocky planets in the tight habitable zones of white dwarfs. Researchers found that orbital precession caused by the theory's effects might decouple inner planets from larger companions, allowing life to persist for trillions of years. This challenges prior models that predicted runaway greenhouse effects on such worlds.
Astronomers discover most pristine star in the universe
Astronomers have identified a star that stands as the most chemically pristine object known in the universe. This exceptional find offers new insights into the early cosmos. The star's composition reveals extremely low levels of heavy elements.
Rogue planet accretes mass at record 6 billion tonnes per second
Astronomers have observed a free-floating planet gaining mass at an unprecedented rate as it plows through the interstellar medium. The rogue world, similar in size to Jupiter, is adding 6 billion tonnes every second in what researchers call a record growth spurt. This discovery highlights how such planets can evolve independently of stars.
Scientists develop new method for dark matter detection
Researchers have announced a breakthrough in detecting elusive dark matter particles using advanced collider technology. The discovery, detailed in a recent Nature publication, could reshape our understanding of cosmic composition. Led by a team at CERN, the method promises more precise measurements than previous attempts.
Webb telescope reveals thousands of newborn stars in Lobster Nebula
7. Oktober 2025 Von KI berichtet
NASA's James Webb Space Telescope has captured a stunning infrared image of the Pismis 24 star cluster within the Lobster Nebula, showcasing thousands of sparkling newborn stars. Located about 5,500 light-years away in the constellation Scorpius, this region highlights massive star formation sculpted by intense radiation and winds. The image provides rare insights into the evolution of hot young stars.
October 2025 sky features supermoon and meteor showers
7. Oktober 2025 Von KI berichtet
Stargazers in October 2025 can enjoy a bright supermoon and two meteor showers lighting up the night sky. The full moon on October 6 will appear larger and brighter, coinciding with the Draconid meteor shower. The Orionids will peak later in the month under dark new moon skies.
Hubble telescope images spiral galaxy NGC 6000
The NASA/ESA Hubble Space Telescope has captured a stunning image of NGC 6000, a spiral galaxy 102 million light-years away in the constellation Scorpius. The picture highlights stars of varying ages, from blue young clusters to a golden older core, while revealing faint remnants of past supernovae. An asteroid photobombed the shot, adding streaks to the cosmic scene.
Galaxies eject matter more violently than expected
A new analysis reveals that supermassive black holes in galaxies fling out baryonic matter far more aggressively than previously thought, explaining the long-missing cosmic gas. Researchers at the University of California, Berkeley combined observations of the cosmic microwave background to map how this ordinary matter diverges from dark matter. The findings highlight the powerful role of black holes in shaping the universe's mass distribution.
Researchers develop new method for detecting gravitational waves
Scientists have announced a breakthrough in gravitational wave detection using advanced quantum sensors. The new technique promises to enhance sensitivity and uncover more cosmic events. This development stems from collaborative research at leading physics institutions.
New Einstein's Cross discovery reveals giant dark matter halo
Astronomers using the Hubble Space Telescope have discovered a new Einstein's Cross, a gravitational lensing phenomenon that exposes a massive dark matter halo surrounding a distant galaxy. This rare quadruple image of a quasar offers fresh evidence on dark matter's extent. The research, led by scientists from Spain's Instituto de Astrofísica de Canarias, appears in Nature Astronomy.
