Article on imaging extrasolar planets
« on: 06/29/2018 10:59 PM »
This is an interesting read about current research on imaging extrasolar planets.

https://www.nasa.gov/feature/jpl/nasa-uses-earth-as-laboratory-to-study-distant-worlds

The article basically says that if you are only getting one pixel from a planet, look at it in 10 different wavelengths to see what's on the surface and different times to see if it rotates.
e^(pi*i) = -1

The upcoming "ELTs" should be able to directly image planets. For example, see "EPICS" on the E-ELT.

Currently we can generally only image very massive, young, and hot self-luminous planets at very wide sperations. The next generation of ground based telescopes and instruments should be able to image older planets at far closer seperations, possibly down to very massive rocky planets in the habitable zone of low mass stars (although they would most likely be tidally locked).

The science that we can do with a pixel of light is pretty exciting!
