There's a nice comparison you can make to pass on the insane scale of the Universe - that if you put the Earth-Sun distance at one inch, then one light year is a mile. So the nearest star is 4.2 miles away. Useful to have in your mind something that's about that distance that will be meaningful to your audience. 3 Link to comment Share on other sites More sharing options...

davehowat Posted October 30, 2022 Share Posted October 30, 2022 As Douglas Adams said ...Space is big. Really big. You just won't believe how vastly hugely mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space.” although your pillar photo and the scale just doesn't do it justice,thanks for making me think how small our world is ,but in a nice way ,,,small but perfectly formed,,if it wasn't for humans lol 1 Link to comment Share on other sites More sharing options...
robin_astro Posted October 30, 2022 Share Posted October 30, 2022 (edited) On the other hand it shows how close together the stars forming in this cloud are relative to the distance to our (next) nearest star Robin Edited October 30, 2022 by robin_astro 1 Link to comment Share on other sites More sharing options...

Gfamily Posted October 31, 2022 Share Posted October 31, 2022 (edited) Here's a great blog post by the fantastic Phil Plait ( the 'badastronomer' ) about what the most recent MIRI image of the Pillars of Creation is showing us. https://badastronomy.substack.com/p/new-jwst-pillars-of-creation-image He includes a link to this ESA image that allows you to slide between the MIRI and NIRCAM images. https://www.esa.int/ESA_Multimedia/Images/2022/10/Webb_s_instruments_showcase_the_Pillars_of_Creation_slider Edited October 31, 2022 by Gfamily Spolling 3 Link to comment Share on other sites More sharing options...

Sunshine Posted December 14, 2022 Share Posted December 14, 2022 So many fuzzies! a Webb deep field mosaic reveals an astonishing amount of ancient galaxies at the very edge of time, amazing. Link below goes to NASA site where one can select a hi-res image to scroll through, I have spent an hour looking through the myriad of galaxies. https://blogs.nasa.gov/webb/2022/12/14/webb-glimpses-field-of-extragalactic-pearls-studded-with-galactic-diamonds/ 2 Link to comment Share on other sites More sharing options...
Sunshine Posted February 1, 2023 Share Posted February 1, 2023 These deef field images are always so grand and humbling, this spiral galaxy looks magnificent, a billion LY from us. https://esawebb.org/images/potm2301a/ 4 Link to comment Share on other sites More sharing options...

From their caption on the image: "The black strip in the center is a chip gap, the result of the separation between NIRCam’s two long-wavelength detectors. The gap covers the dense center of the cluster, which is too bright to capture at the same time as the fainter, less dense outskirts of the cluster. " i.e. cover the bright centre and you see more of the outside. 1 Link to comment Share on other sites More sharing options...

That’s what happens when you get lost looking at the pictures so much you don’t read the article carefully, I am the very definition of an “amateur astronomer” Link to comment Share on other sites More sharing options...
