🌞 🌒 🛰 The Moon transits the Sun, as seen from the vantage point of our Solar Dyamics Observatory satellite on Nov. 7, 2018. There's scientific value in capturing images of these transits: The sharp edge of the lunar limb helps researchers measure how light diffracts around the telescope's optics and filter support grids, allowing scientists to better calibrate their instruments.

Following a week of tests in the Pacific Ocean, Kennedy Space Center's Exploration Ground Systems team is "ready to rock and roll" for recovery of our Orion spacecraft, after it splashes down at the end of Exploration Mission-1. Here, during night operations out in the open water, a test Orion capsule is pulled into the well deck of a U.S. Navy ship.

Here's a look at the majestic beauty of snow, as seen from space. ❄️This photo shows curling snow drifts magnified by the terrain around the 1,400 mile Dnieper River, flowing from Russia to the Black Sea.
@EuropeanSpaceAgency astronaut @thom_astro, a member of the Expedition 50 crew, captured this image from the @iss on Feb. 9, 2017, saying, "winter landscapes are also magical from the International Space Station: this river north of Kiev reminds me of a Hokusai painting." Each day, the International Space Station completes 16 orbits of our home planet as the crew conducts important science and research. Crew members on the space station photograph the Earth from their unique perspective, hovering 200 miles above us, documenting Earth from space. This record is crucial to how we see the planet changing over time, from human-caused changes like urban growth, to natural dynamic events such as hurricanes, and volcanic eruptions.

Inkblot test! 🐉 😜 🌀 🐕 🐙 What do you see in this image by our @NASAJuno spacecraft? We keep finding new shapes hidden in Jupiter's swirling clouds.

Behold: The beauty of our home planet! 😍 The orange hue surrounding Earth, known as airglow, diffuse bands of light that stretch 50 to 400 miles into our atmosphere.
Airglow reveals some workings of the upper reaches of our atmosphere. It can help scientists learn about the movement of particles near the interface of Earth and space, including the connections between space weather and Earth weather. Satellites offer one way to study this dynamic zone. Our Ionospheric Connection Explorer satellite that launches early in the morning of Nov. 7 will help scientists understand the physical processes at work where Earth’s atmosphere interacts with near-Earth space.
Shadows on Earth can be mysterious, but when they occur in space, they can convey information we otherwise could not know.
Nearly 1,300 light-years away, the shadow of the debris from a young star in the form of a "Bat Shadow" spans 200 times the length of our solar system in the Serpens Nebula. The near-infrared vision of our @NASAHubble Space Telescope captured the shadow cast by the fledgling star's brilliant light, revealing secrets of its unseen planet-forming disk.

Icy Ceres and rocky Vesta: two dwarf planets and time capsules from the beginning of our solar system, seen in these images from our Dawn spacecraft. Today, as expected, the Dawn mission came to an end, as the spacecraft has run out of fuel and gone silent. Since arriving at Vesta in the asteroid belt in 2011, and at Ceres in 2015, Dawn's data and images have been critical to understanding the solar system's history and evolution. Dawn is the first mission to orbit an object in the main asteroid belt, the first to visit a dwarf planet, and the first to orbit two deep-space destinations.
Is that a witch screaming out into space?! This infrared portrait shows the Witch Head nebula, named after its resemblance to the profile of a wicked witch. Spotted by our Wide-Field Infrared Survey Explorer, the Witch Head nebula is estimated to be hundreds of light-years away in the Orion constellation. Astronomers say the billowy clouds of the nebula, where baby stars are brewing, are being lit up by massive stars. Dust in the cloud is being hit with starlight, causing it to glow with infrared light that was picked up by our detectors.
