Sunspot region 4114 has fired off its strongest blast yet — an X1.2-class solar flare that erupted on June 17, triggering ...

Explore the profound impact of solar flares on Earth's technology and environment, their classification, effects, and how understanding them is vital for safeguarding our world.

When ejections like this hit Earth’s magnetic field, they can cause solar storms. An ejection like this is known as a solar flare called a coronal mass ejection (CME).

A new sunspot forming on the surface of the sun might be about to fling solar flares in our direction. The sunspot, named 3856, is facing Earth and has developed a volatile type of magnetic field ...

Sunspot AR3078 already launched a moderate-strength solar flare toward Earth on Tuesday morning, with the ... sometimes taking several days to reach Earth. CMEs can alter Earth's magnetic field, ...

This is a sign that the blast produced a coronal mass ejection (CME) that delivered the glancing blow to Earth’s magnetic field yesterday. Since the X1.9-flare, active region (AR) 1302 has ...

A quick look at how a solar flare can cause a geomagnetic storm on Earth, ... The colorful aurora forms when the particles flowing from the sun get caught up in the Earth's magnetic field.

While solar flares arrive at the Earth within 8 minutes of eruption—since they travel at the speed of light—CMEs take a few days, ... When CMEs hit our planet's magnetic field, ...

NASA is launching a fleet of spacecraft Thursday to investigate the mystery behind a cosmic phenomenon in the Earth's magnetic field just as the sun unleashed its first massive flare of the year.

New research led by a Johns Hopkins mathematical physicist focuses on the “misbehavior” of magnetic fields in solar flares. In this image, the Solar Dynamics Observatory (SDO) captured an X1.2 ...

Solar flares and coronal mass ejections tend to occur near sunspots, dark patches as big as Earth that are located near the most intense portions of the sun’s shifting magnetic field.
