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.

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.

Study suggests moon's largest crater formed from northern impact

A new analysis indicates that the moon's South Pole-Aitken basin, its oldest and largest crater, likely formed from an asteroid impact originating from the north rather than the south. This finding challenges previous assumptions about the moon's early history. The discovery could enhance the value of NASA's upcoming Artemis III mission to the basin's rim.

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.

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.

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.

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.

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.

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.

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.

October 2025 sky features supermoon and meteor showers

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.

Webb telescope reveals thousands of newborn stars in Lobster Nebula

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.
