Directly Observing Exoplanets Just Got Easier

So that Gliese Goldilocks Zone planet may not exist. Sad. Cheer up though, because astronomers from Arizona State have discovered a new technique that could make spotting exoplanets a bit easier. That’s great, because right now it’s really frickin’ hard.

The biggest hurdle is light. When we look at distant stars and try to see their planetary systems, the glare from the star can be millions of times brighter than the rocky planets that could inhabit the warm Goldilocks Zone. This is the case with our solar system, whose dusty space and glaring Sun potentially obscure all but Neptune from hypothetical alien observers.

What this amazing new research out of ASU does is reduce the glare by stealing some of the star’s own light.

Using these “ripples” of light the researchers are able to cancel out some of the star’s glare (but only on one side, as seen in the picture). But, what a picture the left side is! That’s a planet, directly observed, orbiting the well-documented Beta Pictoris, visible and glorious thanks to this new technique.
