Explanation: The dark, inner shadow of planet Earth is called the umbra. Shaped like a cone extending into space, the umbra has a circular cross section that can be most easily seen during a lunar eclipse. For example, last Saturday the Full Moon slid across the northern edge of the umbra. Entertaining moon watchers throughout Earth’s eastern hemisphere, the lunar passage created a deep but partial lunar eclipse. This composite image uses successive pictures recorded during the eclipse from Athens, Greece to trace out a large part of the umbra’s curved edge. The result nicely illustrates the relative size of the umbra’s cross section at the distance of the Moon, as well as the Moon’s path through the Earth’s shadow.

Explanation: During a total solar eclipse, the Sun’s extensive outer atmosphere, or corona, is an inspirational sight. The subtle shades and shimmering features of the corona that engage the eye span a brightness range of over 10,000 to 1, making them notoriously difficult to capture in a single picture. But this composite of 28 digital images ranging in exposure time from 1/1000 to 2 seconds comes close to revealing the crown of the Sun in all its glory. The telescopic views were recorded near Kochenevo, Russia during the August 1 total solar eclipse and also show solar prominences extending just beyond the edge of the eclipsed sun. Remarkably, features on the dark near side of the New Moon can also be made out, illuminated by sunlight reflected from a Full Earth.

Explanation: Like the downtown area of your favorite city, the roads you drive to work on, and any self-respecting web site … Io’s surface is constantly under construction. This moon of Jupiter holds the distinction of being the Solar System’s most volcanically active body — its bizarre looking surface continuously formed and reformed by lava flows. Generated using 1996 data from NASA’s Galileo spacecraft, this high resolution composite image is centered on the side of Io that always faces away from Jupiter. It has been enhanced to emphasize Io’s surface brightness and color variations, revealing features as small as 1.5 miles across. The notable absence of impact craters suggests that the entire surface is covered with new volcanic deposits much more rapidly than craters are created. What drives this volcanic powerhouse? A likely energy source is the changing gravitational tides caused by Jupiter and the other Galilean moons as Io orbits the massive gas giant planet. Heating Io’s interior, the pumping tides would generate the sulfurous volcanic activity.

Acid Rain, Washington, D.C., 1981

Photograph by Robert Sisson

In this macro close-up, a bromophemol solution is dripped on raindrops found on a daisy petal to test their acidity. The solution is reddish and has turned one drop yellow. The rain is pH 3, the same as vinegar.
