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 capture sharpest image of M87 black hole jet

Astronomers have obtained the clearest view yet of the powerful jet emanating from the supermassive black hole in the Messier 87 galaxy. Using the Event Horizon Telescope, researchers revealed intricate details of the jet's base. This breakthrough sheds light on how black holes launch such cosmic phenomena.

Astronomers find most distant odd radio circle

Astronomers have discovered the most distant and powerful odd radio circle, a massive double-ringed radio structure nearly 10 billion years old. Using citizen science and the LOFAR telescope, researchers propose these cosmic rings form from galactic superwinds rather than black hole mergers. The finding challenges existing theories and highlights the role of human pattern recognition in astronomy.

Scientists develop quantum sensor for detecting dark matter

Researchers at the University of Cambridge have unveiled a novel quantum sensor designed to detect dark matter particles. The breakthrough, announced on October 2, 2025, could provide new insights into the universe's unseen mass. The technology was detailed in a study published in the journal Nature.

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.

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.

Stargazers have multiple opportunities in 2025 to witness meteor showers, with peaks offering up to 120 shooting stars per hour. The year's displays include the reliable Geminids and Perseids, visible from dark locations worldwide. Optimal viewing requires minimal light pollution and clear weather.

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.

New Einstein's Cross discovery reveals giant dark matter halo

4. oktober 2025 Rapportert av AI

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.
