How long is a day on Saturn?
One of the Cassini mission's goals was to figure out how long a day on Saturn is. We still don't know: https://t.co/ZXDTPe5gDL
How much liquid nitrogen did it take to freeze @NASAWebb for a little more than 90 days? Here are a couple of ways to measure it. (Liquid nitrogen wasn't the only thing we used; read more about how we kept #Webb cool here: https://t.co/fPoz2mGjyE) #JWST
#TBT Last year, a full-scale model of @NASAWebb (#JWST) was on display in Houston at #SuperBowl LI. JWST's infrared sensitivity will help to compare the faintest, earliest galaxies to today's grand spirals & ellipticals, so we can learn how galaxies form over billions of years.
Strange star or rogue planet? @NASAWebb will investigate how the mysterious brown dwarf defies definition. Read more here: https://t.co/LQSsinxRxi #JWST
What is the best way to move an ~14,000-lb (~6,350-kg) telescope? @NASAWebb rides in style inside a massive shipping container called STTARS. Watch the full story on the @NASAViz app, or check out the web version here: https://t.co/c1QFrouiHE #JWST
How do we move @NASAWebb from one location to another? Using a huge, specially designed shipping container called STTARS. Watch the video to see STTARS in action! #JWST
#ICYMI, last week @NASAWebb completed its final cryogenic test at @NASA_Johnson, bringing it one step closer to launch! https://t.co/CDgl7kHklm #JWST Credit: #NASA/Chris Gunn
Astronomers around the world will have immediate access to early data from specific observations from @NASAWebb. These just announced observations will be made within the first 5 months of science operations. https://t.co/rXl2yfL04z #JWST
