A recent solar storm event caused more than just breathtaking auroras across the Northern Hemisphere; it triggered a series of precautions aboard theInternational Space Station (ISS). Astronauts had to adjust their sleeping arrangements to shield themselves from radiation.

The last in a series of three coronal mass ejections hit Earth on Wednesday, so experts are keeping an eye on geomagnetic storm potential

The British Geological Society is warning that the Earth is about to get hit by the most powerful solar storm in over two decades.

The sun has burped out bursts of energy called coronal mass ejections that could reach Earth Tuesday night. Forecasters said the vibrant displays could be visible across much of the northern U.S.

Scientists said the sun erupted Tuesday morning, unleashing a strong X5.1-class flare in an intense outburst, causing communications disruptions.

The rocket will propel NASA’s ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) spacecraft into orbit to begin their journey to Mars.

Increased solar activity causes auroras that dance around Earth’s poles, known as the northern lights, or aurora borealis, and southern lights, or aurora australis. When the energized particles from coronal mass ejections reach Earth’s magnetic field, they interact with gases in the atmosphere to create different colored lights in the sky.

The X5.1-class eruption from sunspot AR4274 is this year's most powerful solar flare and Earth is in the firing line.

The sun has become more and more active over the last 16 years, in a turn that surprised scientists and could affect space weather and technology on Earth, NASA announced this week. A new research, conducted by two NASA scientists and published earlier in ...
