Giant Planet Nine Times the Mass of Jupiter Found 73
cremeglace writes "In the late 1990s, astronomers noticed a distinct warp in the disk of dust and gas orbiting a young star some 60 light-years from Earth. Now, using new analytical tools, researchers have discovered a giant planet lurking within the dusty haze. About nine times as massive as Jupiter and composed mainly of gas, the planet is only a few million years old, proving that such enormous planetary bodies can form rapidly."
What's amazing about this is that the images taken of the star clearly show the planet first on one side of the star, and then the other, several years later.

What's amazing isn't that the planet is orbiting it's parent star, it's the technology to take a picture of the planet and be able to see it moving over time. Most extrasolar planets aren't detected this way, they usually use either Doppler shift or reduction in brightness to detect the existence of a planet and extrapolate from there. There's only a handful of examples of optically sighted extrasolar planets, and this is the first I've heard of having two pictures of the same system, both with the planet visible.
Not only is that 'cool' but it allows us to start cataloging planets that orbit their stars on a plane perpendicular to the direction we are viewing them. Previously, a planet had to conveniently be orbiting such that we were looking into the system edge on. The real excitement will come when we can view terrestrial planets this way with enough resolution to perform spectrographic analysis on the atmosphere and search for, among other things, sings of life.
