coronal mass ejection

Two coronal mass ejections have combined into an enormous cloud of magnetized plasma that is forecast to hit Earth on Tuesday and potentially trigger a weak geomagnetic storm.

The enormous dark patch and its powerful eruption are both signs that the solar maximum is fast approaching — and could be more active than expected.

Scientists studying a star system in Orion witnessed one of the most powerful stellar eruptions ever seen — and it could be devastating to nearby planets.

A stunning composite image of the sun during a recent 'hybrid eclipse' in Australia is further proof that solar activity is ramping up.

Astronomers spotted a massive coronal mass ejection (CME) expanding its ethereal wings as it barrelled out of the sun and toward Mercury.

NASA astronaut Josh Cassada photographed a gorgeous green aurora from space, capturing the impacts of a solar storm that swept over our planet.

The tiny sun used sound waves to simulate the sun's swirling mass of plasma

An amateur astronomer witnessed the moment that the green comet C/2022 E3 had part of its tail blasted away by a coronal mass ejection.

An analysis of eight years of data reveals a possible telltale sign that a region of the sun is about to erupt.

Astronomers recently detected a massive explosion on the far side of the sun, which may have spat out one of the most powerful flares the sun can produce.
