![]() ![]() However, the moon has no atmosphere, so during the transit we can see the crisp edges of the moon's horizon. This is because-while the planet itself completely blocks the sun's light-Earth’s atmosphere is an incomplete barrier, blocking different amounts of light at different altitudes. During these phases, Earth blocks SDO’s view of the sun for anywhere from a few minutes to over an hour once each day.Įarth’s outline looks fuzzy, while the moon’s is crystal-clear. SDO’s orbit usually gives us unobstructed views of the sun, but Earth’s revolution around the sun means that SDO’s orbit passes behind Earth twice each year, for two to three weeks at a time. The United States and much of the world will see skies graced by a. Watch it happen live on Monday, September 26, starting at 6 p.m. (September 27, 2015) Stargazers, night owls and space observers, be prepared, the eclipse of the supermoon is coming. Though SDO sees dozens of Earth eclipses and several lunar transits each year, this is the first time ever that the two have coincided.

When SDO's orbit finally emerged from behind Earth, the moon was just completing its journey across the sun’s face. Explanation: Astronomers turn detectives when trying to figure out the cause of startling sights like NGC 1316. Just as the moon came into SDO’s field of view on a path to cross the sun, Earth entered the picture, blocking SDO’s view completely. 13, 2015, as NASA’s Solar Dynamics Observatory, or SDO, kept up its constant watch on the sun, its view was photobombed not once, but twice.
