If you went outside at exactly the same time every day and took a picture that included the Sun, how would the Sun's position change? With great planning and effort, such a series of images can be taken. The figure-8 path the Sun follows over the course of a year is called an analemma. At the Winter Solstice in Earth's northern hemisphere, the Sun appears at the bottom of the analemma. Analemmas created from different latitudes appear at least slightly different, as well as analemmas created at [...]

Would you like to see a total eclipse of the Sun? If so, do any friends or relatives live near the path of next summer's eclipse? If yes again, then you might want to arrange a visit for one year from today. Next year on this exact date, the path of a total solar eclipse will cut right across the center of the contiguous USA. All of North America and part of South America will experience, at the least, a partial solar eclipse.
Featured here is a map of the path of totality, computed by eclip [...]
Gamma-rays and dust from periodic Comet Swift-Tuttle plowed through planet Earth's atmosphere on the night of August 11/12. Impacting at about 60 kilometers per second the grains of comet dust produced this year's remarkably active Perseid meteor shower. This composite wide-angle image of aligned shower meteors covers a 4.5 hour period on that Perseid night. In it the flashing meteor streaks can be traced back to the shower's origin on the sky. Alongside the Milky Way in the constellation Perseu [...]
Expedition 48 Commander Jeff Williams and Flight Engineer Kate Rubins concluded their spacewalk at 2:02 EDT. During the five-hour and 58-minute spacewalk, the two NASA astronauts successfully installed the first of two international docking adapters (IDAs).
The IDAs will be used for the future arrivals of Boeing and SpaceX commercial crew spacecraft in development under NASA’s Commercial Crew Program. Commercial crew flights from Florida’s Space Coast to the International Space Station wi [...]
CAPE CANAVERAL AIR FORCE STATION, Fla. -- The U.S. Air Force’s 45th Space Wing supported United Launch Alliance’s successful launch of the third and fourth Orbital ATK-built Geosynchronous Space Situational Awareness Program satellites aboard a Delta IV rocket from Space Launch Complex 37B hereat 12:52 a.m. ET.
The AFSPC-6 mission will deliver two GSSAP satellites into orbit to further the space situational awareness mission. Operated by Air Force Space Command, the GSSAP System pro [...]
On the night of August 12, this bright Perseid meteor flashed above volcanic Sunset Crater National Monument, Arizona, USA, planet Earth. Streaking along the summer Milky Way, its initial color is likely due to the shower meteor's characteristically high speed. Entering at 60 kilometers per second, Perseid meteors are capable of exciting green emission from oxygen atoms while passing through the tenuous atmosphere at high altitudes.
Also characteristic of bright meteors, this Perseid left a [...]
