Karen C. Fox, NASA's Goddard Space Flight Center The sun emitted a mid-level solar flare, peaking at 3:01 p.m. EDT on Oct. 2, 2014.  NASA's Solar Dynamics Observatory, which watches the sun 24-hours a day, captured images of the flare. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and...

coronal mass ejection
2014-09-26 03:00:31

Karen C. Fox, NASA's Goddard Space Flight Center Two main types of explosions occur on the sun: solar flares and coronal mass ejections. Unlike the energy and x-rays produced in a solar flare – which can reach Earth at the speed of light in eight minutes – coronal mass ejections are giant clouds of solar material that take one to three days to reach Earth. Once at Earth, these ejections, also called CMEs, can impact satellites in space or interfere with radio communications. During CME...

The Difference Between Flares And CMEs
2014-09-23 03:49:47

[ Watch The Video: The Difference Between CMEs And Solar Flares ] Max Gleber, NASA There are many kinds of eruptions on the sun. Solar flares and coronal mass ejections both involve gigantic explosions of energy, but are otherwise quite different. The two phenomena do sometimes occur at the same time – indeed the strongest flares are almost always correlated with coronal mass ejections – but they emit different things, they look and travel differently, and they have different...

Kasha Patel, NASA’s Goddard Space Flight Center Robert Alexander spends parts of his day listening to a soft white noise, similar to water falling on the outside of a house during a rainstorm. Every once in a while, he hears an anomalous sound and marks the corresponding time in the audio file. Alexander is listening to the sun’s magnetic field and marking potential areas of interest. After only ten minutes, he has listened to one month’s worth of data. Alexander is a PhD...
