With the help of the
Solar and Heliospheric Observatory (SOHO), a satellite built specifically to study the sun, scientists have uncovered some of the sun's best-kept secrets.
Contact with the
Solar and Heliospheric Observatory -Soho - positioned between the Earth and the Sun, was lost on June 24 during a routine operation to alter its orbit.

Solar and Heliospheric Observatory (SOHO), a joint ESA/NASA project, observes the Sun to provide data for space weather prediction.
Well after many casual observers had given up on the comet's survival, updated pictures from the
Solar and Heliospheric Observatory spacecraft-SOHO-showed what appeared to be a long trail of dust extending away from the sun along ISON's trajectory, brightening sharply toward its tip.
The
Solar and Heliospheric Observatory (SOHO) was designed to study the Sun.
Another spacecraft, the
Solar and Heliospheric Observatory, had previously seen hints that CMEs disrupted the tails of two other comets.
Yesterday's mass ejection was spotted by instruments aboard the
Solar and Heliospheric Observatory (Soho) as an expanding halo around the sun.
Even the
Solar and Heliospheric Observatory (SOHO), a satellite designed to study the sun, is not immune.
