play_circle_filled Is there a pot of gold at the end of a green aurora? We're not sure, but these dancing green lights provide a spectacular view that's perfect for the #StPatricksDay holiday. 🍀

This stunning aurora was captured by one of our @NASAastronauts, Jeff Williams, during his 2016 mission on the International Space Station (@ISS). #FlashingLights #NASA #SeeingGreen

@NASAHubble has done it again. This image reveals a globular cluster of stars in the constellation of Sagittarius, 18,000 light-years away from Earth. Don’t forget to shine bright today.

photo_library 3-2-1… LIFTOFF! 🚀 
Today at 3:14 p.m. EDT, three humans left planet Earth on six-hour journey to the International Space Station (@ISS). Launched aboard a Soyuz spacecraft from the Baikonur Cosmodrome in Kazakhstan, @NASAastronauts Nick Hague and Christina Koch, and cosmonaut Alexey Ovchinin will arrive at their new orbiting home later today.

During their time on humanity’s only permanently occupied microgravity laboratory, they will work on hundreds of experiments in biology, biotechnology, physical science and Earth science. They will be joining the trio who is already in space, bringing the total crew to six people.

Cross your eyes and break out the 3D glasses! 😎

Our New Horizons team has new stereo views of the Kuiper Belt object nicknamed Ultima Thule – the target of our New Horizons spacecraft’s historic New Year’s 2019 flyby, four billion miles from Earth – and the images are as cool and captivating as they are scientifically valuable. 
The 3D effects come from pairing or combining images taken at slightly different viewing angles, creating a “binocular” effect, just as the slight separation of our eyes allows us to see three-dimensionally. 
Using images like this, we can better understand the extraordinary shape of the farthest object ever explored

Nothing quite like the chaotic beauty of colliding galaxies. 
The @NASAHubble telescope captured these galaxies crashing into each other inside of the Hercules constellation, about 230 million light-years away. They were first discovered in 1784 by William Herschel and were originally classified as a single irregular galaxy because of their odd shape.

A long time ago, gravity drew the two galaxies together into the chaotic state we now observe. Stars from within both of the original galaxies now follow new paths because of the changes in gravity. Eventually the galaxies will fully merge to form a single, stable galaxy.

Our own galaxy, the Milky Way, will undergo a similar collision in the future with our nearest galactic neighbor, the Andromeda galaxy. However, this is not expected to happen for around 4 billion years.

You’re looking at one of the unsolved mysteries of Mars: the “brain terrain.” 🧠 
The surface texture of interconnected ridges and troughs found in the mid-latitude regions of Mars may be directly related to the water ice that lies beneath the surface. 
One hypothesis is that when the buried water ice changes from a solid to a gas, it forms troughs in the ice. 
This image was taken by the High Resolution Imaging Science Experiment (HiRISE), an instrument onboard the Mars Reconnaissance Orbiter.

It’s supersonic! 💥An advanced air-to-air photo technology test by @NASAAero produced the first-ever images of the interaction of shockwaves from two supersonic aircraft in flight. 
This image features a pair of T-38s from the U.S. Air Force Test Pilot School at Edwards Air Force Base, flying in formation at supersonic speeds — faster than the speed of sound. The T-38s are flying approximately 30 feet away from each other, with the trailing aircraft flying about 10 feet lower than the leading T-38. With exceptional clarity, the flow of the shock waves from both aircraft is seen, and for the first time, the interaction of the shocks can be seen in flight.

Originally monochromatic and shown here as a colorized composite, this image was captured during a supersonic flight series flown, in part, to better understand how shocks interact with aircraft plumes, as well as with each other.

The data from these flights will help us progress toward quiet supersonic research flights with the X-59’s Low-Boom Flight Demonstration and closer toward a major milestone in aviation.

This is the Cigar Galaxy (also called M82), a starburst galaxy about 12 million light-years away in the constellation Ursa Major. 
Using our @SOFIATelescope observatory, researchers found the galactic wind flowing from the Cigar Galaxy weighs quite a lot: it carries the equivalent mass of 50 to 60 million Suns in gas and dust! Aligned along a magnetic field, the wind transports these materials into intergalactic space. 
The magnetic field is shown as streamlines in this composite image, which combines starlight (gray) and a tracing of hydrogen gas (red) from the Kitt Peak Observatory, with near-infrared and mid-infrared starlight and dust (yellow) from SOFIA and the Spitzer Space Telescope.

In its historic inaugural flight, the Falcon 9 rocket with the @SpaceX Crew Dragon successfully launched from Launch Complex 39A at the @NASAKennedy Space Center in Florida on March 2, 2019. On March 3, the spacecraft autonomously docked with the International Space Station (@ISS), representing one more crucial step in getting our Commercial Crew Program off the ground.

This first-of-its-kind mission, called Demo-1, is the first flight test of a space system designed for humans built and operated by a commercial company. In addition to 400 pounds of supplies, the Crew Dragon spacecraft is carrying Ripley, an anthropomorphic test device outfitted with sensors to gather important data about what an astronaut flying aboard the spacecraft would experience throughout the mission.
