December 9, 2008This is outstandingly amazing. And clever. Philly P breaks it down (as he does best) for the non-technical:
They got a spectrum of the star and the planet at the same time, and then waited until the planet was behind the star and got a spectrum of just the star by its lonesome. By subtracting the star’s spectrum from the star+planet spectrum, they got the spectrum of just the planet itself.
Because I am Not an Astronomer (TM), I often tell people in my theater that astronomy is something that I really have to do my homework on, because there is literally new astronomy news every single day. This is a perfect example of that.
I can only imagine that this technique will become more and more easy and prolific, and we’ll be learning lots of extra things about extrasolar planets in the very near future.
One of the readers of my blog passed this site onto me, interesting !!
