Astronomy Picture of the Day

                         Astronomy Picture of the Day

    Discover the cosmos! [1] Each day a different image or photograph of our
 fascinating universe is featured, along with a brief explanation written by a
                           professional astronomer.

Explanation: If you were floating above the Earth right now, this is what you
might see. In 2014, a robotic SpaceX [5] Dragon capsule [6] that delivered
supplies to the Earth-orbiting International Space Station [7]  (ISS) also
delivered High Definition Earth Viewing [8] (HDEV) cameras that take and
transmit live views of Earth. Pictured here [9] , when working, is the live
video feed that switches between four cameras, each pointed differently. Watch
white clouds, tan land, and blue oceans [10]  drift by. The featured live view
[11]  will appear black when it is nighttime on the Earth below [12] , but the
space station's rapid 90-minute orbit [13] compresses this dark time into only
45 minutes. The present location of the ISS above the Earth can be found on
the web [14] . If the video appears gray, this indicates that the view is
either being switched between cameras, or communications with the ISS is
temporarily unavailable. As the HDEV project [15]  continues, video quality
will be monitored to assess the effects of high energy radiation, which types
of cameras work best, and which Earth views [16]  are the most popular.
