Popular Post L.A.T.1961 Posted July 11, 2022 Popular Post #1 Share Posted July 11, 2022 This first image from NASA’s James Webb Space Telescope is the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail. Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length https://www.nasa.gov/webbfirstimages 12 1 Top Link to comment Share on other sites More sharing options...
L.A.T.1961 Posted July 11, 2022 Author #2 Share Posted July 11, 2022 NASA and its partners will release the full series of Webb’s first full-color images and data, known as spectra, Tuesday, July 12, during a live NASA TV broadcast. https://www.nasa.gov/image-feature/goddard/2022/nasa-s-webb-delivers-deepest-infrared-image-of-universe-yet 5 1 Top Link to comment Share on other sites More sharing options...
Trelane Posted July 11, 2022 #3 Share Posted July 11, 2022 Truly amazing. Everyone involved in this project should be very proud of this accomplishment. Deep, wide and mysterious the universe remains. She smiles at us, but still has much to reveal. 7 Top Link to comment Share on other sites More sharing options...
L.A.T.1961 Posted July 11, 2022 Author #4 Share Posted July 11, 2022 A great achievement, so many ways it could have gone wrong but now hopefully a telescope that will keep delivering for twenty years. 4 Top Link to comment Share on other sites More sharing options...

+razman Posted July 12, 2022 #6 Share Posted July 12, 2022 Yea , it is extraordinary pic, fascinating how large the universe is. If you think of a person's body being made up of cells and molecules and stuff and they say (like anything that appears solid ) , it is actually mostly space in between , then this is like looking at a microscopic view of a universal body. 4 Top Link to comment Share on other sites More sharing options...

L.A.T.1961 Posted July 12, 2022 Author #8 Share Posted July 12, 2022 More new images - Stephan’s Quintet, a visual grouping of five galaxies. https://www.nasa.gov/webbfirstimages Also on that link - Southern Ring Nebula, and a light spectrum of WASP-96 b used to detect its atmospheric makeup. WASP-96 b is one of more than 5,000 confirmed exoplanets in the Milky Way. https://www.nasa.gov/image-feature/goddard/2022/nasa-s-webb-reveals-steamy-atmosphere-of-distant-planet-in-detail 4 2 Top Link to comment Share on other sites More sharing options...

To think, they're just getting started! I wonder what other secrets and mysteries the Webb team can reveal or solve. 4 Top Link to comment Share on other sites More sharing options...

NCC1701 Posted July 12, 2022 #12 Share Posted July 12, 2022 You can clearly see the dent that that meteorite struck in the mirror in the concentric rings around the middle of the image. Link to comment Share on other sites More sharing options...
Gumball Posted July 12, 2022 #13 Share Posted July 12, 2022 This is the stuff of dreams. To even try and imagine how big our galaxy is or how many stars and planets lie within is amazing but to then see five all stuck together is mind blowing.

+razman Posted July 13, 2022 #16 Share Posted July 13, 2022 (edited) The pics look almost 3D when you look close at them, though it seems like there is a lot of contrast in some of them , especially that of the Carina Nebula . I mean the similarities of cells and wombs and molecules is uncanny , like maybe our microscopic selves and some basic life stuff are based loosely on the universe design. Like just looking at a super giant version of our microscopic bodies. This look familiar. Like cells in a microscope.

Cons: The universe is too vast, there's no way we'll ever meet aliens, You have a valid point (cons), Jethro. What we are looking at there are images that were made some 14 billion years ago. We'll never have any idea as to what is going on NOW. The closest star to Earth (besides the sun), Proxima Centauri, is 4.2465 light-years away. And yet, it would take 60,000 years to get there. (estimates vary depending on technology used).

An excerpt from https://phys.org/news/2022-07-full-color-images-james-webb-telescope.html Quote Crafting the images is also something of a subjective process. Artists at the institute must essentially assign color to black and white images as scientifically as possible, creating visual representations of wavelengths of light that humans cannot see. 1 Top Link to comment Share on other sites More sharing options...

An excerpt from https://phys.org/news/2022-07-full-color-images-james-webb-telescope.html The idea of true colour is not straight forward with any images, even a standard mobile phone camera uses filters over a mono imaging cmos/ccd and then the, usually, three filter colours used combined to create a colour image. How the colours are combined will provide the colour balance seen in the image, many domestic cameras will have a slightly different balance depending on the processing algorithm used. With the Webb telescope the cameras have been set up to operate at the designed wavelength of the scope for best scientific results, its a research tool first that can have its output modified on the ground to give a colour image the public can engage with. 1 Top Link to comment Share on other sites More sharing options...
NCC1701 Posted July 14, 2022 #23 Share Posted July 14, 2022 Probably they just shifted the wavelength to visible range, so short wavelength is still blue and red for the longer wavelenght. Just a guess. Link to comment Share on other sites More sharing options...
