Astronomers have discovered a rogue intermediate-mass black hole speeding through a dwarf galaxy 230 million light-years away. Unlike typical galactic centres, this displaced object is accreting material and blasting out jets, suggesting black holes can grow “offsite”. The finding offers rare evidence of elusive intermediate black holes and may help explain how supermassive black holes expanded rapidly in the early universe.

Astronomers have identified asteroid 2025 PN7 as a possible quasi-moon of Earth, trailing our planet for nearly 70 years. At just 62 feet wide, it is the smallest and least stable quasi-satellite detected so far. Researchers believe advanced observatories like the Vera Rubin Observatory could uncover more hidden companions in Earth-like orbits

A giant butterfly-shaped coronal hole on the Sun is blasting solar wind toward Earth, expected to trigger geomagnetic storm conditions on Sept. 13–14. Forecasts suggest possible G1 to G2 levels, raising chances for auroras across mid- and high-latitudes. Scientists note the equinox effect could intensify activity, offering a prime opportunity for skywatchers to witness dazzling displays.

Astronomers now predict a 90% chance of detecting an exploding primordial black hole within a decade. Such an event would confirm Stephen Hawking’s theory that black holes evaporate, releasing a flash of radiation and exotic particles. Detecting one would revolutionize physics and rewrite our understanding of the universe.

Researchers in China have developed a DNA “cassette tape” that stores data at densities far beyond current drives. By encoding digital files into DNA strands embedded on tape, the system allows compact, sustainable archival storage. A 100-meter DNA tape could hold 36 petabytes, reshaping the future of data centers.

Researchers have engineered a cobalt-nickel-vanadium alloy that stays tough even at –186°C, resisting the brittleness that plagues most metals in extreme cold. Using atomic-scale design, the team created dual structural patterns inside the alloy that block cracks and preserve ductility. In lab tests, the metal absorbed far more strain than conventional steels.
