Honestly with everything the Webb telescope has seen anything is possible.

This is one of my favorite science channels. Because he goes very in-depth on topics of Astronomy. Most people who talk on the topic give you a surface-level description.

@@LaunchPadAstronomy Very true. I've got a Bsc in physics (with quite some astronimy courses) and love your explanation. It is really at a level and depth that I apprentice and don't often find in popular media, unfortunately

_"It's the clearest, obvious, can't be anything else, no kidding signature of CO2 ever seen in a exoplanet."_ Sounds like they’re being wishy-washy about the result. They need add a smily face & thumbs up emoji in their paper to drive it home. But seriously... My God, this is *absolutely incredible!*

I love this channel, because even though the news about this topic were released days before, you can always learn more details and more information about what actually happened to get to this result. Props for that, Christian!

Wow! Really amazing that this was done in a single transit. Thanks for explaining Transmission Spectroscopy!

Great work as always thank you! I do have to say though I feel sorry for Spitzer lol, it seems to be the go to example when people want to say "hey look at how terrible our old telescopes were compared to Webb, glad we're done with that garbage." Spitzer was a good telescope! It discovered the Trappist system! #teamspitzer

Agreed, Spitzer was awesome!

Really enjoyed this one. It's truly great what our technology can do; I've found myself wondering how exactly are we capable of determining planetary compositions from such vast distances. With this video, I can now grasp onto the concept with more clarity. Thank you, and as always keep up the good work.

May I ask, when can we expect to get detailed data on Trappist-1? I heard that some data was made public a while ago but I have not seen further since

You know Webb was worth all those billions at the rate it's shucking out new discoveries......

Amazing

What you described is pretty much exactly subtracting spectrum of star occluded by the planet from spectrum of star not occluded by the planet. I believe the real complexity here is in modelling, because shading of individual wavelengths depends on whole lot of factors, not just on chemical composition. I'd guess diameter of the planet, thickness of atmosphere and differences in light bending and scattering in the atmosphere for individual wavelengths are among factors that need to be accounted for.

So James Webb will be able to detect on proxima centauri b the planet composition??

And a scientist working on it is from India. Niser bhubaneswar

Can JWT be able to find exoplanets at a distance ?

@LaunchPadAstronomy

It wouldn’t be suitable for finding exoplanets, but if detected by a survey telescope like TESS or TRAPPIST, then Webb would be good at studying it in greater detail.

When they are making these measurements, is Webb focused on that specific star system?

It is. It watches the star and measures the tiny dropoff in its brightness as the planet transits in front.

How a planet that big can evolve with its atmosphere intact that close to its host star? Still interesting result. It will be more interesting if Webb can detect gas in smaller rocky planet.

Yeah, I didn't get into the whole origin story, but they likely formed further away from the star where there were more gases/volatiles available and migrated inward as they dragged against the surrounding disk.

If it’s bright enough to be the dominant source of light, then sure. Figuring out that it’s from a manufactured source is another matter.
