Scientists peering into the atmosphere of a giant planet 130 light years away believe their findings bolster one theory of how solar systems form.

The planet, orbiting the star HR 8799, is part of a solar system containing at least three other "super-Jupiters" weighing in at between five and 10 times the mass of our own Jupiter. The nearby system features a brash, young 30-million-year-old star (by contrast, our Sun is in midlife at about 4.5 billion years old).

Physicists Tie Water Into Knots

Reporting in the journal Nature Physics, William Irvine and Dustin Kleckner, physicists at the University of Chicago, have created a knotted fluid vortex in the lab โ€” a scientific first, they say. The knots resemble smoke rings โ€” except these are made of water, and they're shaped like pretzels, not donuts. Understanding knottiness has extra-large applications, like understanding dynamics of the sun.
