From Oct. 22 to Nov. 4, 2003, the Sun produced some of the most extreme events on record. Here, data is combined from multiple instruments on multiple spacecraft revealing the exploding flare and continuing on to the CME leaving the Sun and blasting toward Earth. Credit: NASA / ESA

Earth - Movie 3

Right: Solar particles bombard the polar cap, penetrating the upper atmosphere (stratosphere). This excess radiation prompted an alert by the FAA for aircraft to fly at lower altitudes away from the poles. Images from POES spacecraft. Credit: NOAA/University of Michigan.

Mars reacts to solar storms differently than Earth because it has no significant magnetic field, but a series of small, localized fields as in the animation. As a result, the supersonic solar wind directly interacts with the Martian ionosphere allowing oxygen to escape. Credit: NASA / Nagoya University; Credit: NASA

Between November 2003 and April 2004, Ulysses was aligned with Jupiter. The inset graph from Ulysses reveals increases in magnetic field strength related the blast with spikes on Nov. 13 and 15. The majority of the blast wave arrived at Cassini near Saturn around Nov. 11 and continued through Nov. 21. Credit: NASA

Voyager 2, located about 7 billion miles (11 billion km) from the Sun, experienced the solar blast around mid-May while its counterpart, Voyager 1, (over 8 billion miles away), is expected to see the blast in early July. Credit: NASA

The heliosphere is the region where solar wind reigns supreme. The"Halloween storms" were so intense, that they also affect the boundaries of this region. Scientists predict within 10 months the shock wave will reach the heliopause and expand the region by as much as 1.5 billion miles. Credit: NASA
Space Radiation Hazards
 
An important safety concern for long term space travel is the health effects from space radiation. Possible health risks include cancer, cataracts, acute radiation sickness, hereditary effects, and damage to the central nervous system. Credit: NASA.
