I just can’t compute how this is possible. How can a telescope detect a gas, which isn’t even visible to the naked eye, on a planet that is an incomprehensible distance away.

It amazes me all of the science that had to happen, building on each other findings, over decades …. to get to a point where we can tell what gasses are on a distant plant by how the light passes through them. So cool and really not appreciated (I think)
