Have they released any images of the galactic center yet?

  I imagine that, along with any data for TRAPPIST, is on the [very long] list of things to do. Otherwise I'm sure it'd be posted here in no time

  The galactic center image won't be as fancy, unfortunately. Resolution of Webb is far-far-far too low to see anything related to the black hole, the best we could do is enhance the view of the stars near Sgr A* [1]. 1. https://www.eso.org/public/videos/eso0226a/ https://www.eso.org/public/videos/eso0226a/

    Webb resolution is about 0.1 arc-seconds (wavelength dependent) [1]. Event Horizon Telescope (EHT) resolution is about 25 micro arc-seconds (wavelength dependent) [2]. So roughly speaking, since you cannot really compare the two, since they observe on quite different wavelengths, EHT has ~4000 times better resolution than Webb. Note that we don't speak about sensitivity here. ALMA array of radio telescopes has a collecting area of 7000 m2, while it is just one of many "nodes" of the EHT. Webb total collecting area is about 25 m2. 1. https://www.jwst.nasa.gov/content/about/faqs/faq.html#sharp https://www.jwst.nasa.gov/content/about/faqs/faq.html#sharp 2. https://eventhorizontelescope.org/technology https://eventhorizontelescope.org/technology

    Understood, but it still would be very interesting to see the area with JWST's full range of instruments.
