Astronomers Discover Rogue Black Hole Racing Through a Distant Dwarf Galaxy

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.

Butterfly-Shaped Hole in the Sun Could Spark Solar Storms Worldwide This Weekend

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.
