NASA is calling it "The Rose." By any other name, it's a mammoth storm on Saturn's north pole. Its eye spans an estimated 1,250 miles — 20 times the size of an average hurricane's eye on Earth. Winds in the Saturn storm's eye wall are believed to be four times as fast.
The stunning image of the spinning vortex was given "false colors" to emphasize low clouds (in red) versus high clouds (in green). NASA estimates that the clouds at the outer edge are moving at up to 330 miles per hour.
Last year's drought wreaked havoc on farmers' fields in much of the Midwest, cutting crop yields and forcing livestock producers to cull their herds. This spring, the rain that farmers needed so badly in 2012 has finally returned. But maybe too much, and at the wrong time.
It's almost the end of April, which is prime time to plant corn. But farmers need a break in the rain so they can get this year's crops in the ground and try to lock in good yields at harvest.

Scientists can't just agree to disagree. It's not because we are stubborn or ornery (OK, maybe we are). It's because the whole point of science is to establish "public knowledge" — an understanding of the cosmos on which we can all agree. That is why there is trouble brewing at the beginning of the Universe.
There is a number, the Hubble Constant, that's fundamental to the study of the cosmos. The problem is, different folks are finding different values for that number and no one yet knows what that means.
Most research on memory loss in the elderly focuses on dementia, Alzheimer's disease or other brain diseases.
But neuroscientist Emily Rogalski from Northwestern University's Feinberg School of Medicine knew there is great variation in how good memory is in older people. Most have memory loss to varying degrees, but some have strong memories, even well into old age.
Same-sex marriage got huge headlines at the Supreme Court last month, but in the world of science and medicine, the case being argued on Monday is far more important. The lawsuit deals with a truly 21st century issue — whether human genes may be patented.
It's widely known that the world's icecaps are melting. While most people are focused on what we're losing, some have considered what might be gained by the disappearance of all that ice.
In 2008, the U.S. Geological Survey released a report estimating that 13 percent of the world's remaining undiscovered oil and 30 percent of the remaining undiscovered natural gas could be in the Arctic.
A top executive at News Corp. dropped a bombshell this week when he said the company is considering taking Fox's over-the-air network to cable. The announcement follows a court win for a startup company that streams broadcast channels online.
That startup's CEO, arguably the most feared man in television right now, is soft-spoken and rather techy.
