Comet Pan-STARRS is putting on a bit of a show for those in the Northern Hemisphere through the end of this month. We're seeing some beautiful photos, such as those taken this week by AFP/Getty's Stan Honda. He pointed his camera skyward near Magdalena, N.M.

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).

And the Bushes just keep on coming.

In recent memory, there was George H.W. Bush, 41st president of the United States. Then there was George W. Bush, 43rd president. And now there's John Ellis "Jeb" Bush, who may want to become the 45th president.

Jeb is sending mixed signals: Tonight he is a keynote speaker at a Conservative Political Action Conference dinner, but he has asked that his name be removed from CPAC's 2016 presidential straw poll.

Does Jeb have what it takes to be the next president of the United States?

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 — a scientific first, they say. The knots resemble smoke rings — 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.
