A dynamic world of dunes, plains, craters & terrains is revealed in this first-ever geologic map of Saturn's moon, Titan. Lakes and seas are marked blue, but they aren't water! What rains down is methane and ethane in Titan's frigid climate.

For decades, astronomers have looked for galaxy clusters containing rich nurseries of stars in their central galaxies. Instead, they found powerful, giant black holes pumping out energy and keeping the gas too warm to form many stars.
We are going, together. American companies are joining our #Artemis program to provide science & technology deliveries to the lunar surface.

LIVE: Hear from scientists who have traveled to the ends of the Earth to launch sounding rockets, flown cutting-edge instruments on these suborbital flights, and used sounding rockets to make brand-new scientific discoveries. Watch: https://twitter.com/i/broadcasts/1yoJMzMvdWkxQ
To study oxygen particles where Earth's atmosphere leaks into space, scientists traveled to the Arctic and launched a sounding rocket — into an aurora! At 2pm ET, join us to learn about these rockets & how they're used for science.
Confirmed: there's water vapor present above the icy surface of Jupiter's moon Europa.
A research team led from @NASAGoddard made the detection — which supports the idea that below the ice, Europa has an ingredient necessary for life: liquid water.

Unfathomable science & teamwork. The Alpha Magnetic Spectrometer is an instrument seeking to unlock the mystery of dark matter. To keep it running, a world of scientists, engineers & astronauts have been working for years to design a complex repair job. https://www.nasa.gov/johnson/HWHAP/alpha-magnetic-spectrometer-the-spacewalks/
With a flight time of ~15 minutes before falling back to Earth, sounding rockets collect data about the atmosphere, Sun & even distant galaxies.
Join our experts to learn about this cutting-edge science:

As a winter-like chill engulfed the eastern U.S. this mid-November, our @NASAEarth satellites captured these “cloud streets.” Cloud streets occur when a column of moist air rises and hits a warmer air layer, causing it to roll over on itself.

"We hope that it's all metal. That would be great." In @NASAJPL's "On a Mission" podcast, we've heard about threats from asteroids, but what about their potential? The lead scientist of our Psyche asteroid mission explains.

In preparation to search for ancient life on Mars, our #Mars2020 rover scientists visit the Australian Outback to investigate the oldest evidence for life on Earth. Though seemingly unrelated, the 2 locations share some eerie similarities.

A Kuiper Belt object spotted by @NASAHubble & visited by @NASANewHorizons was officially named this week. With consent from Powhatan Tribal elders and representatives, it is now known as "Arrokoth," meaning “sky” in the Powhatan/Algonquian language.

Up, up, down, down - do the Neptune Moon dance! Partners w/ chemistry AND rhythm, Moons Naiad & Thalassa are caught in a “dance of avoidance” choreographed so precisely that neither steps on the other one’s toes. How do they make it work?
