They could also create a magnetic field that would damage the satellite's systems. The image on the left was taken on November 15, 1999. Fortunately, the atmosphere absorbs most of these high-energy rays. What is a sunspot, anyway? If high-energy rays were to hit a , they could strip electrons from the metal components, ionizing them. Exploratorium, in partnership with the Center for Extreme Ultraviolet Astrophysics at the University of California, Berkeley. As electrons break free, they could short out the electronics within a satellite.

Excel Easy: 1 Excel tutorial on the net. Close inspection of the Sun's surface reveals a turbulent tangle of magnetic fields and boiling arc-shaped clouds of hot plasma dappled by dark, roving sunspots. Objective The goal of this project is to determine whether there is a correlation between coronal mass ejection activity and the solar sunspot cycle, using historical data. Humans in space or at high altitudes -- on board an , for example -- could risk exposure to intense radiation. However, if scientists learn to predict coronal mass ejections, humans can take preventative measures here on Earth.

If is in the path of that shockwave, our planet's magnetic field will react to the event. The monthly sunspot number is the average of all the daily numbers for the month. However, scientists have made a new discovery, recently published in , about how solar flares occur and erupt. Reproduction of one of Galileo's sunspot drawings from his book on the subject, published in 1613. Think for a moment about how many people must have contributed to the endeavor over more than three hundred years of daily observations! Media If a media asset is downloadable, a download button appears in the corner of the media viewer. Another interesting project involving sunspots is to recreate Galileo's experiments using satellite imagery that you can collect online. As the atoms in the gases recombine with electrons they emit light.

Did you also know that the sun sometimes releases huge bursts of electrified gases into space? In 1859, a plume of magnetized plasma shot 93 million miles from the sun to the Earth in less than a day. A coronagraph produces a solar eclipse by covering the Sun with a small disk. About Parsec vzw Parsec vzw is a non-profit organization from Belgium which consists of several websites about Astronomy, Space, Space Weather, aurora and related subjects. There might only be one coronal mass ejection every week. They usually occur in pairs or groups of opposite polarity that move in unison across the face of the Sun as it rotates. The solar sunspot cycle has been observed for hundreds of years, a long time span compared to a human life, but not even an eye blink compared to the life of the sun 4.

This way, the data is reliable even when small spots are hard to visualize. That could overload electrical systems and cause massive damage.

If no button appears, you cannot download or save the media. It's similar to what happens if you put a weak magnet next to a strong one.

Graph shows the number of sunspots visible on the sun for every month from the year 1749 to 2005. Statisticians use the power of math and probability theory to answer questions that affect the lives of millions of people. Their theories are then applied to human-scale projects to bring people new technologies, like computers, lasers, and fusion energy. Survivalist websites, like , recommend taking precautions against solar flares just as you would for any other natural disaster: learn to purify water, and keep an emergency kit on hand with flashlights, medical supplies and non-perishable foods.
