Making sense of Saturn’s impossible rotation

Posted by in categories: physics, space

Saturn may be doing a little electromagnetic shimmy and twist which has been throwing off attempts by scientists to determine how long it takes for the planet to rotate on its axis, according to a new study.

Discovering the length of a day on any planet seems like a straightforward task: Find some feature on the planet and clock it as it rotates around once. Or, if it’s a gas giant like Jupiter, which has no solid surface features, scientists can listen for periodic modulations in the intensity of radio signals created within the planet’s rotating magnetic field.

And then there is Saturn, which for decades has defied attempts to pin down out its exact rotation period. Now a new study in AGU’s Journal of Geophysical Research: Space Physics may have finally unveiled the gas giant’s trick for hiding its rotation, and provide the key to giving up its secret.

The physicists’ library

Posted by in category: physics

To compile the ultimate science reading list, Tushna Commissariat talks to some of today’s top physicists, writers and broadcasters.

“What an astonishing thing a book is. It’s a flat object made from a tree with flexible parts on which are imprinted lots of funny dark squiggles. But one glance at it and you’re inside the mind of another person, maybe somebody dead for thousands of years. Across the millennia, an author is speaking clearly and silently inside your head, directly to you.”

Astronomer, science communicator and author Carl Sagan always had a way with words, and it’s no surprise that he sums up so well the magic of books and writing. From the very first issue of Physics World, this magazine has featured a vibrant reviews section, in which we look at some of the most interesting physics literature being published.
