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.
Astronomers have detected a massive Coronal Mass Ejection (CME) from the red dwarf star StKM 1-1262, located 130 light-years away.
This stellar eruption is estimated to be 10,000 to 100,000 times more powerful than the Sun's strongest CMEs.
The CME was ejected at a speed of 5.3 million miles per hour.
The discovery marks the first direct observation of a CME originating from a star outside our solar system.
Such powerful stellar events could potentially strip a nearby planet of its atmosphere, indicating a significant danger in extrasolar space weather.
