NASA detects solar flare pulses at Sun and Earth

When our Sun erupts with giant explosions—such as bursts of radiation called solar flares—we know they can affect space throughout the solar system as well as near Earth. But monitoring their effects requires having observatories ...

Saturn's radiation belts: A stranger to the solar wind

The radiation belts of Earth and Saturn differ more strongly than previously assumed. In these belts, very energetic particles, such as electrons and protons, move around the planet at high velocities - captured by its magnetic ...

An Earth-like atmosphere may not survive Proxima b's orbit

Proxima b, an Earth-size planet right outside our solar system in the habitable zone of its star, may not be able to keep a grip on its atmosphere, leaving the surface exposed to harmful stellar radiation and reducing its ...

NASA sees the sun having a solar blast (w/ video)

Giant solar tornadoes put researchers in a spin

Despite their appearance solar tornadoes are not rotating after all, according to a European team of scientists. A new analysis of these gigantic structures, each one several times the size of the Earth, indicates that they ...
