The latest data sent back by the Juno and Cassini spacecraft from giant gas planets Jupiter

The latest data sent back by the Juno and Cassini spacecraft from giant gas planets Jupiter and Saturn have challenged a lot of current theories about how planets in our solar system form and behave. googletag.cmd.push(function() { googletag.display(‘div-gpt-ad-1449240174198-2′); }); The detailed magnetic and gravity data have been “invaluable but also confounding,” said David Stevenson from Caltech, who will present an update of both missions this week at the 2019 American Physical Society March Meeting in Boston. He will also participate in a press conference describing the work. Information for logging on to watch and ask questions remotely is included at the end of this news release. “Although there are puzzles yet to be explained, this is already clarifying some of our ideas about how planets form, how they make magnetic fields and how the winds blow,” Stevenson said. Cassini orbited Saturn for 13 years before its dramatic final dive into the planet’s interior in 2017, while Juno has been orbiting Jupiter for two and a half years. Juno’s success as a mission to Jupiter is a tribute to innovative design. Its instruments are pow...

Electricity is a mystery to most of us. But even if you don’t know AC from

Electricity is a mystery to most of us. But even if you don’t know AC from DC or volts from watts, if you’ve traveled outside the United States, you are aware that plugs and outlets are different in other countries. In fact, there are about 15 types of electrical outlets in use throughout the world. When you want to plug in one of your devices abroad, you’ll need an adapter, which serves as a sort of “go-between” as it plugs the appropriate prong style into the socket and your cord plugs into the external side of the adapter. And here’s where it gets a bit more complicated. In many countries — most in fact, except for the U.S. and Canada — the electrical voltage is 220/240V. Our American devices are designed for 110/120V which is not compatible, even when correctly plugged in through an adapter. You know this first-hand if you’ve ever fried a hair dryer or curling iron while traveling. This is where the converter comes in. A travel power converter converts or “steps down” the electrical voltage from the outlet to 110/120V so that American devices can be used safely. One more thing: many devices are now made “dual voltage,” enabling them to be used with both 110/120V and 220/240...
