Hubble Trouble with Hakeem Oluseyi

Yeah. So Nancy Grace Roman, going back to the ASP, she valued the ASP so much that when she passed away recently, she left the organization a few million dollars. Whoa. Yeah, yeah.

Absorption spectrum. Yeah. Yeah. So it happens in two ways. So what's absorbing what? So what happens is that when you look at a transit of an exoplanet, so that means that it'll go in front of its star, right? And so at that time, the light from the star will pass through the atmosphere of the planet.

So I'm getting light in my telescope. So as that planet is going in front of a star, if it has an atmosphere, the light from the star passes through the planet's atmosphere and that light interacts with that atmosphere around the edges. That light interacts. And so certain wavelengths of light aren't going to make it out the other side. They're going to be absorbed.

By the chemistry of the atmosphere. By the chemistry of the atmosphere. But remember, the star has its own spectrum as well. So you get a spectrum of the star by itself. You get a spectrum when the light is passing through the planet's atmosphere and you subtract them. And what's left over is a spectrum of the planet.

And now you can say, oh, I see this element or a molecule in that particular atmosphere.

And so James Webb Space Telescope was built to do that job, and it actually has succeeded in doing that job. Those are some of the early release, like, look, hey, we can do it.

Well, first off... Trivia. My very first physics research... That's what I was wondering. You were in that. ...was summer of 91 on the cold dark matter... CDMS, right? In the basement in Berkeley. Okay. Building the dark matter direct detection, right? Which we've not detected any dark matter yet. So your PhD is from... No, no, no. It's a funny thing. I got accepted.

I applied to Berkeley and Stanford. I got rejected from Berkeley, accepted by Stanford. You idiot got rejected by Berkeley.
