Pine Island Glacier has shed another block of ice into Antarctic waters. The loss was tiny compared to the icebergs that broke off in 2014 and 2015, but the event is further evidence of the ice shelf’s fragility.
Expedition 50 Flight Engineer Thomas Pesquet of the European Space Agency shared this photograph from the International Space Station on Feb. 14, 2017, writing, "Venice, city of gondoliers and the lovers they carry along the canals. Happy Valentine's Day!"
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.
The Andromeda constellation is one of the 88 modern constellations and should not be confused with our neighboring Andromeda Galaxy.
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.
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.
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 new iceberg poised to break away soon.
Seen from outside, Enceladus appears to be like most of its sibling moons: cold, icy and inhospitable.
