photo: The Moon passing in front of the Sun, as taken by the STEREO-B spacecraft on February 25, 2007. Because the satellite is in an Earth-trailing orbit and is further from the Moon than the Earth is, the Moon appears smaller than the Sun.
photo: Solar "fireworks" in sequence as recorded in November 2000 by four instruments onboard the SOHO spacecraft.
photo: The heliospheric current sheet extends to the outer reaches of the Solar System, and results from the influence of the Sun's rotating magnetic field on the plasma in the interplanetary medium.
photo: History of the number of observed sunspots during the last 250 years, which shows the ~11-year solar cycle.
photo: Coronal mass ejections blast filaments and bubbles of magnetic plasma into space as seen in this ultra-violet light picture taken by SOHO.
photo: Measurements of solar cycle variation during the last 30 years.
photo: Taken by Hinode's Solar Optical Telescope on January 12, 2007, this image of the Sun reveals the filamentary nature of the plasma connecting regions of different magnetic polarity.
photo: During a total solar eclipse, the solar corona can be seen with the naked eye.
photo: The effective temperature, or black body temperature, of the Sun (5777 K) is the temperature a black body of the same size must have to yield the same total emissive power.
