The most powerful solar flares, X-class flares, have the most significant effect on Earth.
The twisted magnetic fields can snap back and explode, powering solar flares and coronal mass ejections.
Along the way the astronauts would be bombarded by cosmic radiation and risk being baked by unpredictable solar flares.
CMEs are often, but not always, accompanied by solar flares, which are huge ejections of radiation from the Sun.
FORBES: NASA Reports That Solar Flares Could Disrupt Power, Communications
Solar flares are one of our most serious threats for our communication systems.
The rooms' outer walls are each filled with 250lbs of insulating polyethylene to protect astronauts during solar flares and damaging ultraviolet radiation.
If so, promising planets may have been sterilized by solar flares or frozen in the past, which wouldn't be reflected in present-day habitable-zone calculations.
During decades of trial and error, the Stanford University scientists overcame engineering glitches, launch delays, budget fights, solar flares, faulty data and seven federal investigations.
WSJ: Researchers Spent $750 million��and 52 Years��Affirming Theory of Relativity
Solar flares, such as this one, are magnificient to behold.
FORBES: No, A Giant Solar Flare Will Not Destroy The Earth In 2012
Bett Padgett, who heads the Outer Banks Lighthouse Society, which petitioned the federal government for funds to restore Bodie Island's once-crumbling lighthouse, warns of solar flares knocking out satellites.
During Solar Max or solar maximum, the sun tends to exhibit more sunspots and eruptions, and jettison more solar flares, which send powerful streams of charged particles into the solar system.
Astronauts would also be bombarded with solar energetic particles, which get accelerated close to the sun as a result of solar flares and coronal mass ejections that shoot portions of the sun into space.
Solar experts believe that the tachocline may be the source of powerful magnetic fields that produce strong solar flares and solar winds, and create sunspots that mysteriously appear and disappear during an 11-year cycle.
These intense solar flares were observed by a British scientist named Richard Carrington back in 1859 who correlated them as the cause of spontaneous combustion of telegraph wires and offices - the relatively tiny telecommunications infrastructure then-available to be disrupted.
Instead, the temperature record shows an up and down pattern that follows the pattern of natural influences on global temperatures, such as cyclical sunspots and solar flares, and cycles of ocean churning from warmer to colder temperatures and back, such as the Pacific Decadal Oscillation (PDO).

Proposed sources of such high heating in the early solar nebula have included everything from colliding asteroids, gamma ray bursts, solar x-ray flares, even lightning in the proto-planetary disk itself.
