Astronomers Find 70 Planets Without Stars Floating Free in the Milky Way
The field of extrasolar planet studies continues to reveal some truly amazing things about our Universe. After decades of having just a handful of exoplanets available for study, astronomers are now working with a total of 4,884 confirmed exoplanets and another 8,288 awaiting confirmation. This number is expected to increase exponentially in the coming years as next-generation missions like the James Webb Space Telescope (JWST), Euclid, PLATO, and the Nancy Grace Roman Space Telescope (RST) reveal tens of thousands more.
With James Webb Space Telescope’s huge sunshield in place, focus shifts to big mirrors
The Webb team can now turn to the next big-ticket item on its list: getting the telescope's secondary and primary mirrors into the proper configuration. But it'll take a while to check those boxes.

Success! Webb Sunshield Now Fully Deployed
If you felt a little more tension – and perhaps more goosebumps — in the Universe today, it’s probably because the James Webb Space Telescope’s sunshield is now completely and successfully deployed! All five layers of the sunshield have been fully extended and “tensioned” into the final taut, kite-shaped configuration. This is a huge accomplishment (and huge relief) for the entire international Webb mission

Mission controllers started the delicate work of tightening the five razor-thin layers of the James Webb Space Telescope’s sunshade Monday. Managers said the nearly $10 billion observatory is “hunky-dory” after pausing deployments over the weekend to adjust the observatory’s power levels and ensure motors needed for the tensioning are in tip-top shape.
Things are getting tense for NASA's James Webb Space Telescope, literally
On Monday (Jan. 3), James Webb Space Telescope controllers began tightening the tension on its massive sunshield.
