A Solar Eclipse from the Moon

Has a solar eclipse ever been seen from the Moon? Yes, first in 1967 — but it may happen again next week. The robotic Surveyor 3 mission took thousands of wide angle television images of the Earth in 1967, a few of which captured the Earth moving in front of the Sun. Several of these images have been retrieved from the NASA archives and compiled into the above time-lapse video. Although the images are grainy, theEarth’s atmosphere clearly refracted sunlight around it and showed a beading effect when some paths were blocked by clouds. Two years later, in 1969, the Apollo 12 crew saw firsthand a different eclipse of the Sun by the Earth on the way back from the Moon. In 2009, Japan’s robotic Kaguya spacecraft took higher resolution images of a similar eclipse while orbiting the Moon. Next week, however, China’s Chang’e 3 mission, including itsYutu rover, might witness a new total eclipse of the Sun by the Earth from surface of the Moon. Simultaneously, from lunar orbit, NASA’s LADEE mission might also capture the unusual April 15 event. Another angle of this same event will surely be visible to people on Earth — a total lunar eclipse.

Region IC 1396

IC 1396  is ionized gas region located in the constellation Cepheus about 2,400 light years away from Earth.
Such embedded, dark, tendril-shaped clouds contain the raw material for star formation and hide protostars within the obscuring cosmic dust. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a large region on the sky, spanning over 5 degrees.
