Flying hundreds miles above, astronauts aboard the International Space Station photographed Lake Hazlett and Lake Willis in Western Australia's Great Sandy Desert. Hundreds of ephemeral salt lakes are peppered throughout the arid Australian Outback.
This Hubble infrared image is part of an observing program that imaged 41 massive galaxy clusters to find the brightest distant galaxies for theJames Webb Space Telescope to study.
At NASA's Kennedy Space Center, organisms in a Petri plate are exposed to blue excitation lighting in a Spectrum prototype unit. NASA scientists and engineers are developing experiments to determine how different organisms, such as plants, microbes or worms, develop under conditions of microgravity.

Saturn's graceful lanes of orbiting ice -- its iconic rings -- wind their way around the planet to pass beyond the horizon in this view from NASA's Cassini spacecraft.
This Hubble image shows what happens when two galaxies become one. The twisted cosmic knot seen here is NGC 2623 — or Arp 243 — and is located about 250 million light-years away in the constellation of Cancer (The Crab).
Jupiter’s moon Amalthea casts a shadow on the gas giant planet in this image captured by NASA’s Juno spacecraft.
