A new way to find life on another planet

[watchingfromafar]

Our search for life on another planet needs to look for a light source that did not come from a sun.

Humans produce light unlike the sun—

If you can find a light source with this wave length, you have found what we have been looking for----

Agreed. But the strategy they use -- analyzing the chemical compounds in a planet's atmosphere (they can tell by its color, as I understand it) -- is supposedly the easiest way.

However, whatever the hell works, I'm all for it. Look for light sources too, you bet.

There's no guarantee intelligent life has to share the same visible spectrum we do.

The amount of light we produce on earth is trivial compared to the Sun's reflection. I'd guess we'd need instruments orders of magnitude better than what we have now.

Yes, because we cannot directly resolve these planets. They are too small and too far away.

So the Webb telescope will peer at their atmosphere spectra in infrared as the planets transit their parent stars.

And would also have to resolve the dark sides of theseplanets in visible light. Which means the will be between us and their parents stars. Which means their parent star's glare will be insurmountable.

Radio waves would be better.

One more human light source

Radio waves would be better.

Personally, I do not believe it is one or the other.

We should be scanning the galaxy for bad 90's TV show reruns.

I just stumbled across this lying clickbait on YouTube. In the comment section people were quick to accept the title even though it was a lie. People are so easily manipulated

I didn't see one single comment where anyone believed the video title.

But the problem is, we would not actually be seeing that wavelength. We know for a fact that the "light" we see from distant objects are not their actual color. That is why we use computers and filters to process it to return them to what we would expect to see.

Plus, the amount of light is insignificant and completely overwhelmed by the light given off by it's star. Might as well say you are going to identify a match by it's wavelength from 200 meters away inside of a brightly lit sports stadium.
