So geht Planetarium (auch), 99 Jahre nach seiner Erfindung: kosmische Visuals gegen Ende von "Hello 2022" - da kann das neue Jahr ja kommen!pic.twitter.com/5wb6sE18Iv

People often ask, "If astronomers spotted a dangerous asteroid, would they tell us?" Hell yeah! As Amy Mainzer says, "Most scientists I've met, the challenge is getting them to stop talking." Info about near-Earth asteroids is all publicly accessible. https://cneos.jpl.nasa.gov/sentry/ pic.twitter.com/zrHrBhXIIi

Today's JWST To-Do items are complete; keep up the awesome work, JWST team! If you are following along with your own To-Do list, post a picture below! Need a copy? Download at http://tinyurl.com/jwstToDo pic.twitter.com/1dhYsHz6an

Tune into NASA TV in the coming days for LIVE coverage of #NASAWebb's final deployments as we #UnfoldTheUniverse. https://www.nasa.gov/live  Post final deployments, there will be a media briefing. See this release for more detail: https://www.nasa.gov/press-release/nasa-plans-coverage-of-webb-space-telescope-deployments …pic.twitter.com/nQRkXF83cU

Das letzte Live-Konzert des Jahres hat in der - unter Pandemie-Regeln - ausverkauften Kuppel begonnen ... und "Hello 2022" steht ganz im Zeichen der Erinnerung an *die* Fördererin der Elektronischen Musik in Deutschland, Sylvia Sommerfeld, die vergangene Nacht verstorben ist.pic.twitter.com/JJvzI0IHuo

So far the @NASAWebb Team is checking all the boxes. The new challenges come Tomorrow 12/31/21 with the Sunshield Port Side Mid-Boom Extenstion (9:20 AM EST) Followed by the Starboard side. (12:20 AM EST) All times approximate.pic.twitter.com/GwURRxv70c

Orbital data for the Persei stage stranded in LEO and the 3 debris objects. You can see that one debris object has high drag and has probably now reentered, while Persei (blue) is dense and will stay up for a while.pic.twitter.com/50LllMI7B9

Find it hard to get out from under the covers in the morning? Imagine doing it in space! Our sunshield covers protected the sunshield while it was folded for launch. Today those covers were removed to prep for unfolding the sunshield! https://blogs.nasa.gov/webb/2021/12/30/webb-team-releases-sunshield-covers … #UnfoldTheUniversepic.twitter.com/t3DbSxpIH9

Great footage from @RealtraSpace camera of NASA/ESA/CSA James #Webb Space Telescope as it separates from its @Arianespace @ariane5 upper stage and unfolds its solar panel, 25 December 2021 https://www.esa.int/ESA_Multimedia/Videos/2021/12/Webb_separation_from_Ariane_5 … #WebbFliesAriane #VA256 #JWST @ESA_Webb @NASAWebb @csa_ascpic.twitter.com/zpjG3ikx7l

We just successfully deployed our aft (back) momentum flap, which helps balance pressure from solar radiation on Webb's sunshield, much like a trim tab helps stabilize a boat or plane! Sail on, Webb! https://blogs.nasa.gov/webb/2021/12/30/webbs-aft-momentum-flap-deployed/ … #UnfoldTheUniversepic.twitter.com/CVAzB6wFhP

One of #Webb’s unique design features is using passive cooling by a five-layer sunshield to reach the telescope’s operational temperatures of 45 kelvins (-230 °C). It spans 21 by 14 meters when deployed, or roughly the size of a tennis court.
