When seen up close, the F ring of Saturn resolves into multiple dusty strands. This Cassini view shows three bright strands and a very faint fourth strand off to the right. To source

The Andromeda constellation is one of the 88 modern constellations and should not be confused with our neighboring Andromeda Galaxy. To source

Jeanette Scissum joined NASA’s Marshall Space Flight Center in 1964 after earning bachelor’s and master’s degrees in mathematics from Alabama A&M University. Scissum published a NASA report in 1967, “Survey of Solar Cycle Prediction Models,” which put forward techniques for improved forecasting of the sunspot cycle. To source

A sunrise photo of Edwards Air Force Base’s Rogers Dry Lake was taken after heavy rainfall in southern California. NASA’s Armstrong Flight Research Center is seen in the foreground. To source

The Larsen Ice Shelf is situated along the northeastern coast of the Antarctic Peninsula, one of the fastest-warming places on the planet. In the past three decades, two large sections of the ice shelf (Larsen A and B) collapsed. A third section (Larsen C) seems like it may be on a similar trajectory, with a […]

Seen from outside, Enceladus appears to be like most of its sibling moons: cold, icy and inhospitable. To source

The Calabash Nebula, pictured here is a spectacular example of the death of a low-mass star like the sun. To source

Dr. George Carruthers, right, and William Conway, a project manager at the Naval Research Institute, examine the gold-plated ultraviolet camera/spectrograph, the first moon-based observatory that Carruthers developed for the Apollo 16 mission. Apollo 16 astronauts placed the observatory on the moon in April 1972. To source

This panorama, photographed by an astronaut aboard the International Space Station, shows nearly the full length of Lake Powell, the reservoir on the Colorado River in southern Utah and northern Arizona. Note that the ISS was north of the lake at the time, so in this view south is at the top left of the […]

Martha Chaffee, widow of Roger Chaffee, Sheryl Chaffee, daughter, and Roger Purvenas, son of Sheryl Chaffee, left, along with acting NASA Administrator Robert Lightfoot, right, place wreaths at the graves of Apollo 1 crewmembers Virgil “Gus” Grissom and Roger Chaffee as part of NASA’s Day of Remembrance, Tuesday, Jan. 31, 2017.

Dione’s lit hemisphere faces away from Cassini’s camera, yet the moon’s darkened surface features are dimly illuminated in this image, due to Saturnshine. To source

Astronauts, from the left, Gus Grissom, Ed White II and Roger Chaffee stand near Cape Kennedy’s Launch Complex 34 during training for Apollo 1 in January 1967. To source

Uranus’ moon Miranda is shown in a computer-assembled mosaic of images obtained Jan. 24, 1986, by the Voyager 2 spacecraft. Miranda is the innermost and smallest of the five major Uranian satellites, just 480 kilometers (about 300 miles) in diameter. Nine images were combined to obtain this full-disc, south-polar view.
