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.

Mysterious cold streak puzzles astronomers in cosmic background

A peculiar cold region in the cosmic microwave background, known as the Cold Spot, continues to baffle scientists despite years of study. Discovered over a decade ago, this anomaly appears cooler than its surroundings and may hint at large-scale structures in the universe. Researchers remain uncertain about its cause, with theories ranging from statistical flukes to massive voids.

Meteor showers to illuminate 2025 night skies

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.

Scientists uncover hidden energy mechanism in M87 black hole

Astrophysicists at Goethe University Frankfurt have simulated how the supermassive black hole M87* powers its massive particle jet using a new numerical code. Their findings reveal that magnetic reconnection, alongside the traditional Blandford-Znajek mechanism, extracts rotational energy from the black hole. This discovery explains the immense jets that influence galaxy evolution.

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.

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.

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.

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.

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.
