Orbiting more than 200 miles above Earth, the planet we call home, the crew aboard the International Space Station snapped this image of the Earth’s limb, or horizon, with the Sun’s glint beaming off the Pacific Ocean and San Francisco Bay on Nov. 1, 2020.

This is the official portrait of the Expedition 1 crew, the first humans to live aboard the International Space Station. Arriving on station on Nov. 2, 2000, they were the first of 64 crews to live and work aboard the orbital laboratory. During a Jan. 30, 1996, press conference in Washington, DC, Vice President Al Gore and Russian Prime Minister Viktor S. Ch...
Night aboard the International Space Station can seemingly look like every spooky sci-fi movie you’ve ever seen. This image shows two empty spacesuits seemingly colluding as most of the astronauts slept. This is one of several images snapped by European Space Agency astronaut Alexander Gerst during his first stay on the orbital laboratory in 2014. Duri...
Active regions on the sun combined to look something like a jack-o-lantern’s face on Oct. 8, 2014. The active regions appear brighter because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona. This image blends together two sets of wavelengths at 171 and 193...
This illustration shows the lightning phenomenon known as a sprite and what a sprite could look like in Jupiter’s atmosphere. Named after a mischievous, quick-witted character in English folklore, sprites last for only a few milliseconds. They feature a central blob of light with long tendrils of light extending down toward the ground and upward. In Ea...
NASA astronaut Kate Rubins points to the International Space Station’s “voting booth” where she cast her vote from space this month. This is actually Rubins’ second time to vote from low-Earth orbit, having cast her first vote from space in 2016 when she was an Expedition 48-49 crew member. Voting in space has been possible since 1997...
This illustration shows Jezero Crater — the landing site of the Mars 2020 Perseverance rover — as it may have looked billions of years go on Mars, when it was a lake. An inlet and outlet are also visible on either side of the lake. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial li...
In this spectacular image captured by the NASA/ESA Hubble Space Telescope, the galaxy NGC 2799 (on the left) is seemingly being pulled into the center of the galaxy NGC 2798 (on the right). Interacting galaxies, such as these, are so named because of the influence they have on each other, which may eventually result in a merger or a unique formation. Already...
