It essentially sees in heat radiation, not visible light. It’s up there specifically to detect infrared light, the faintest and farthest light in the cosmos. Why the colors in Webb’s photos are fakeĪre the Webb telescope images colorized? Are the colors in space photos real? No, they are not. “We plan things out, upload them to the observatory, take the data and get them back down on Earth-then we have another long period of time where we process the data,” said Pontoppidan. However, the DSN will soon be upgraded from slow radio transmissions to super-fast “space lasers” that could massively increase data rates to as much as 10 or even 100 times faster. The data comes in at a ponderous couple of megabits per second (Mbps). Radio waves are very dependable, but slow. There are three complexes in the DSN, each placed 120º from each other California, Madrid in Spain and Canberra in Australia. That's done by using NASA JPL’s Deep Space Network (DSN), which is how engineers communicate with, and receive data from, its 30+ robotic probes in the solar system and beyond-including Webb. ![]() ![]() NASA, ESA, CSA, and STScI NASA, ESA, CSA, and STScI How Webb’s data gets back to Earthīefore engineers can get to work manipulating Webb’s images the raw data has to be returned to our planet from a million miles away in space.
