Webb Telescope Image Gallery
- java-man 4y agoAbsolutely stunning images! Just look at Wolf-Rayet 140 https://webbtelescope.org/contents/media/images/01GEJB2906TM9VR2FSJ4TFMNQM https://webbtelescope.org/contents/media/images/01GEJB2906TM... I wish they dropped that awful orange slider on mouse over...
- bobbob1921 4y agoAgreed on the mouse over
- berkut 4y agoIt's unfortunately missing quite a few, e.g. like the Jupiter images: https://blogs.nasa.gov/webb/2022/08/22/webbs-jupiter-images-showcase-auroras-hazes/ https://blogs.nasa.gov/webb/2022/08/22/webbs-jupiter-images-... (agree again about the obnoxious orange mouse-over).
- echelon 4y agoMy favorite results from Webb are the ones we can't "see": transit and emission spectra. I'm hoping we pick up on an exoplanet venting hallmark biologicals. Or maybe, just maybe, industrials. That would profoundly change our lives forever. https://webbtelescope.org/contents/media/images/2022/042/01GB31683PJ2BNS77065ZZE6CQ?page=3&filterUUID=91dfa083-c258-4f9f-bef1-8f40c26f4c97 https://webbtelescope.org/contents/media/images/2022/042/01G... https://webbtelescope.org/contents/media/images/01GCW1EQ0GNDYECND5NPKGQN27?page=2&filterUUID=91dfa083-c258-4f9f-bef1-8f40c26f4c97 https://webbtelescope.org/contents/media/images/01GCW1EQ0GND...
- alfor 4y agoI heard that by looking farther away we should see older less formed galaxy but that it isn’t the case. Do someone know something about it?
- aizyuval 4y agoForms of lights and our capture of it creates our “vision”. The longer the distance it took the light to travel from the objects to our telescope, the more time it takes. By the time it is finally captured, we are watching an outdated light! An outdated galaxy. I hope that’s what you meant.
- alfor 4y agoYes, but I heard that they appear similar to the closer one, in opposition to what was expected.
- pkaye 4y agoWhat I heard it now they think galaxies started forming pretty early after the big bang.
- dredmorbius 4y agoThere's also the hypothesis of angular diameter turnaround: that at a sufficient distance, more distant objects would appear larger rather than smaller, because they subsumed a larger fraction of the universe at the time. This has not been observed by JWST so far as I'm aware. Memorialised in an xkcd comic, of course (Explain version linked here): <https://www.explainxkcd.com/wiki/index.php/2622:_Angular_Diameter_Turnaround https://www.explainxkcd.com/wiki/index.php/2622:_Angular_Dia...> See also: <https://threadreaderapp.com/thread/1516548836709343238.html https://threadreaderapp.com/thread/1516548836709343238.html>
- rvnx 4y agoDoes someone know why the Webb telescope give this strange "sharp glare" on many of the shiny star-shaped objects ? Is it some sort of AI upscaling or is it raw data coming from the sensors ?
- pkaye 4y agoThose are diffraction spikes. They are caused by the segmented mirrors and struts. Even the Hubble telescope has them just a different shape. The spikes are more noticeable on brighter point like objects like stars. https://en.wikipedia.org/wiki/Diffraction_spike https://en.wikipedia.org/wiki/Diffraction_spike
- dtgriscom 4y agoCan they be processed away? I presume that if the central pixel saturates then the calculations get more fraught, but it should still be possible.
- pkaye 4y agoAccording to Dr Becky (https://www.youtube.com/watch?v=385JLByRtVE https://www.youtube.com/watch?v=385JLByRtVE) there are ways to remove it but its not a perfect process.
- habibur 4y agoBrowsing nightmare. Why does the image gets covered as soon as I focus on it?
- de6u99er 4y agoYes, the experience on mobile browsers is horrible.
- dtgriscom 4y agoThis. It's like I'm pointing at various things in a room, and there's someone running around with a big "This One?" sign that they keep moving in front of my object of interest. Workaround: point at one thing while looking at another.
