Right now, half of the crew members on board the International Space Station are American astronauts who are getting ready to celebrate Thanksgiving and they have a message for us. Check in with NASA’s Christina Koch, Jessica Meir and Andrew Morgan to learn more about what the holiday means to them – and get a look at what Thanksgiving in space will be like in 2019. youtube.com/watch?v=VkFSqdoTSm

A new image of the Tycho supernova remnant from Chanda shows a pattern of bright clumps and fainter holes in the X-ray data. nasa.gov/mission_pages/chandra

There’s an adage that it’s not healthy to skip meals. Apparently, a supermassive black hole in the center of a galaxy millions of light years away has gotten the message. nasa.gov/mission_pages/chandra

NASA’s Chandra X-ray Observatory has captured many spectacular images of cosmic phenomena over its two decades of operations, but perhaps its most iconic is the supernova remnant Cassiopeia A. nasa.gov/mission_pages/chandra

In a galaxy hosting a structure nicknamed the "Teacup," a galactic storm is raging. nasa.gov/image-feature/storm-r

Scientific investigations conducted aboard the International Space Station the week of Dec. 9 included studies of protein crystal growth and how changes in gravity affect the way a person manipulates an object. nasa.gov/mission_pages/station

​Astrophysicists are redrawing the textbook image of pulsars (the dense, whirling remains of exploded stars) thanks to NICER, an X-ray telescope aboard the International Space Station. NICER data has provided the first precise and dependable measurements of both a pulsar’s size and its mass, and the first-ever map of hot spots on its surface. nasa.gov/feature/goddard/2019/

Crew members conducted a variety of investigations aboard the International Space Station during the week of Dec. 2, including research into wearable health sensors and using DNA to understand how humans, plants and microbes adapt to living in space. nasa.gov/mission_pages/station

The first satellite built by students in Mexico for launch from the International Space Station is smaller than a shoebox but represents a big step for its builders. nasa.gov/mission_pages/station

Sometimes robots need a place to stay in space, too. NASA is attaching a “robot hotel” to the outside of the International Space Station with the upcoming launch of the Robotic Tool Stowage (RiTS), a protective storage unit for critical robotic tools. nasa.gov/feature/goddard/2019/

Current scientific research conducted aboard the International Space Station includes investigations on maintaining human health in space, the body’s circatidal cycle and growing moss in microgravity. nasa.gov/mission_pages/station

NASA Television will provide live coverage of the launch and docking of a Russian cargo spacecraft delivering almost three tons of food, fuel and supplies to the International Space Station beginning at 4:15 a.m. EST Friday, Dec. 6. nasa.gov/press-release/nasa-te

NASA commercial cargo provider SpaceX is now targeting 12:29 p.m. EST Thursday, Dec. 5, for the launch of its 19th resupply mission to the International Space Station under contract with the agency. nasa.gov/press-release/nasa-to

​NGC 3175 is located around 50 million light-years away in the constellation of Antlia (the Air Pump). The galaxy can be seen slicing across the frame in this Hubble image, with its mix of bright patches of glowing gas, dark lanes of dust, bright core, and whirling, pinwheeling arms coming together to paint a beautiful celestial scene. nasa.gov/image-feature/goddard

In this image from December 2000, the Expedition One crew--the first to permanently inhabit the International Space Station--are about to eat a treat of fresh oranges. nasa.gov/image-feature/a-treat

This image of North and South America at night is a composite assembled from data acquired by the Suomi NPP satellite in April and October 2012. nasa.gov/image-feature/brillia

To make room for the latest cargo craft on Nov. 29, Progress 73 departed the station after undocking from the Pirs docking compartment. nasa.gov/image-feature/progres

Some of the most dramatic events in the universe occur when certain stars die — and explode catastrophically in the process. When these star deaths, or supernovae, occur, their brightness can rival the light of a whole galaxy. The galaxy NGC 5468, shown in this Hubble image, has hosted a number of these supernovae the past 20 years. nasa.gov/image-feature/goddard
