James Webb infrared Photos

You've all seen beautiful photos on the Internet with James Webb. But I want to tell you a little about how it works. This telescope sees very far. So far that dinosaurs did not exist yet(and your mom).

And how? Very simple: thanks to infrared cameras that catch light from the most ancient objects(not your mom), such as the first galaxies.

Due to the expansion of the Universe, this light shifts to the infrared range. Hubble, for example, works in the optical range. Therefore, even if it really wanted to, it couldnt. Here is the anti-motivation for your life...

So, let's continue about James Webb.

The peculiarity of the telescope is its low operating temperature of about -233 ° C, which is provided by a huge solar shield. It protects against the heat and light of the Sun, Earth and Moon, keeping the telescope cool and preventing "exposure" from its own heat. Now it is the most powerful infrared telescope.

A great question follows. Well, of course, great infrared telescope, but how do it get such beautiful photos if it is infrared, and not optical?

The answer is tricky: the resulting images are processed to make them visible to us. This is done using "false colors", where infrared data is recoded into visible colors (for example, infrared is displayed in red, green, and blue). This way, we can see details and structures that would be invisible in normal light.

So, the next time you see those stunning space photos, just remember: it's all a trick, like when your mom says she's proud of you😘
