Title:
X-ray Transit Of Mercury Title X-ray Transit Of Mercury Title
Explanation:
This sequence of [ http://www.solar.is…] false color X-ray images captures a rare event - the passage [ http://www.arrakis.…] or transit of [ http://www.dsellers…] planet Mercury in front of the Sun. Mercury's small disk [ http://www.seds.org…] is silhouetted against the bright background of X-rays from the hot Solar Corona [ http://antwrp.gsfc.…]. It appears just to the right of center in the top frame and moves farther right as the sequence progresses toward the bottom. The dark notch is a coronal hole near the Solar South Pole [ http://ulysses.jpl.…], while a flaring coronal bright point can be seen to the left of the notch in the top frames. The frames were recorded [ http://www.lmsal.co…] on November 6, 1993 by the Soft X-ray Telescope [ http://www.lmsal.co…] on board the orbiting Yohkoh satellite [ http://www.lmsal.co…]. Transits of Mercury (and Venus) were historically used to discover the geometry of the solar system [ http://beast.as.ari…] and to map planet Earth [ http://pacific.vita…] itself.
