Planets glow most brightly in the infrared.
If you want to detect and study planets around other stars, you go into the infrared.
If you go further back into the depths of time and space that the Hubble Deep Field showed, the galaxies will be redshifted into the infrared.
So if you want a Deep Field even deeper and further back than the Hubble Deep Fields, you go into the infrared.
The places where stars are formed glow most brightly in the infrared.
So if you want to study star formation, you go into the infrared.
This is why the James Webb Space Telescope is an infrared telescope.
Already in its first few months of service, James Webb has discovered water in the atmosphere of a planet around another star
And carbon dioxide in the atmosphere of another.
This could be how we discover alien life. (for more on that, go two pages up to 'and this is how we are looking for E.T.')
Just thought you might like to know!
We live in very exciting times! (2022)
God loves you! Give E.T. and all the baby stars and galaxies my regards!
Sincerely,
