NASA Image of the Day: Visualization of the August 21, 2017 Total Solar Eclipse
On August 21, 2017, the Earth will cross the shadow of the moon, creating a total solar eclipse. Eclipses happen about every six months, but this one is special. For the first time in almost 40 years, the path of the moon’s shadow passes through the continental United States.

NASA Image of the Day: Deployment of the Space Station’s Roll Out Solar Array Experiment
Over the weekend of June 17-18, engineers on the ground remotely operated the International Space Station’s Canadarm2 to extract the Roll Out Solar Array experiment from the SpaceX Dragon resupply ship. The experiment will remain attached to the Canadarm2 over seven days to test this advanced, flexible array that rolls out like a tape measure.

NASA Image of the Day: Celebrating Flag Day
NASA astronaut Jack Fischer took this photograph of an American flag in one of the windows of the International Space Station’s cupola, a dome-shaped module through which operations on the outside of the station can be observed and guided. Throughout NASA’s history, spacecraft and launch vehicles have always been decorated with flags.

NASA Image of the Day: Illustration of Cool Dust Around an Active Black Hole
This artist illustration shows the thick ring of dust that can obscure the energetic processes that occur near the supermassive black hole of an active galactic nuclei. Researchers have found that the dust surrounding active, ravenous black holes is much more compact than previously thought.

NASA Image of the Day: Watching a Volatile Stellar Relationship
In biology, “symbiosis” refers to two organisms that live close to and interact with one another. Astronomers have long studied a class of stars – called symbiotic stars – that co-exist in a similar way. Astronomers are gaining a better understanding of how volatile this close stellar relationship can be.
