A SOLAR STORM AND THE PLEIADES: Before the launch of the Solar and Heliospheric Observatory (SOHO) in 1995, astronomers had never seen anything like this. Behold, a solar storm passing directly in front of the Pleiades:  SOHO recorded this rare conjunction on May 21st. An erupting filament of magnetism near the sun's north pole propelled the CME into space just as the Seven Sisters were passing by. Electra, Taygete, Maia, Celaeno, Alcyone, Sterope, and Merope spent nearly three hours shining through the translucent solar storm. When SOHO left Earth almost 30 years ago, it carried the first realtime coronagraph into space. Coronagraphs are devices that create an artificial eclipse, blocking the glare of the sun to reveal nearby stars, planets, and comets. No telescope on Earth could see something as faint as the Pleiades only a few degrees from the sun, but SOHO does it all the time. |
