Astronomers Detect Powerful Stellar CME, 10,000 Times Stronger Than Sun's

Scientists have seen a giant explosion from a star far away, kind of like a super-powered version of solar storms that create auroras on Earth.

This explosion, called a CME, is a huge burst of hot gas and magnetic fields.

It's much bigger and stronger than anything our Sun can produce, potentially being 10,000 times more powerful.

This event is significant because it's the first time astronomers have directly observed such an eruption from a star outside our own solar system.

The star, named StKM 1-1262, is a red dwarf.

This discovery helps scientists understand space weather beyond Earth and could reveal if such powerful events could harm planets nearby.
