I am confused because I thought it was an infrared telescope?
Are these images as received, or are they frequency shifted post processed into the visible range?
- whimsicalism 4y agoAlmost all images are frequency shifted, often just to what makes things look cool. Still makes it cool IMO!
- dougmwne 4y agoYes, they are frequency shifted. Many telescope images are in false color. I can understand that we are interested in visible light since that’s most within our experience, but the human eye was not evolved for the astronomical and universal so we need some help. Frequency shifting is a tool just like a lens.
- airstrike 4y agoDid you expect 100% black jpgs all around?
- clint 4y agoHumans cannot see infrared light
- astrange 4y agoYou can feel it if it's transmitted as heat rays.
- willis936 4y agoAs others have said: there is frequency shifting done. However, it is important to know that distant galaxies are red shifted making the visible spectrum be in IR. In the case of JWST the frequency shifted images may be close to the non-redshifted visible spectrum.
- layer8 4y agoIt’s just your monitor doesn’t support infrared color space and therefore shows the wrong colors. ;)
- brandmeyer 4y agoI don't know which filters were used to generate these mediagenic images, but you can see the available filters here: https://jwst-docs.stsci.edu/jwst-near-infrared-camera/nircam-observing-modes/nircam-imaging https://jwst-docs.stsci.edu/jwst-near-infrared-camera/nircam... Note that the "colors" used in that graphic are also false, since only F070W and F090W are in the human eyeball's passband.
