Weather Channel looks at wild, deadly weather in solar system

Some of the universe's most extreme tempests, cyclones and rainstorms are visualized in stunning form in a new series premiering this week on The Weather Channel.
"Deadliest Space Weather," a six-part series, begins Thursday at 9 p.m. EST (8 p.m. CST).
The series investigates wild weather systems throughout our solar system, such as violent winds on Saturn, dust storms on Mars, and acid rain on Venus that could eat through steel. One planet has lightning bolts 10,000 times more powerful than any on Earth.
A preview clip of the series details Jupiter's Great Red Spot, the largest storm in the solar system, where winds can reach 400 miles per hour (640 kilometers per hour).
What would happen if such a storm were to arise on Earth, where no hurricane has ever had winds surpassing 200 mph (320 kph)?
"Hurricanes on Earth already do extensive damage," University of California, Berkeley astronomer Alex Filippenko says in the series. "Well, think of one with 400-mile-an-hour winds. If you double the speed, that's actually four times the energy of these swirling particles. It would really cause a lot of damage."
That kind of tempest would qualify as a Category 20 hurricane on Earth, experts said.
 
Each week, the show will profile another amazing instance of jaw-dropping space weather, and then describe, in terrifying detail, what such climatic tantrums could do on our own planet.
"Exploring these unique weather phenomena in our solar system is a fascinating journey, but one understands the true magnitude of these galactic storms so much more when they are theoretically placed into the familiar context of life on Earth," Michael Dingley, senior vice president of content and development at The Weather Channel, said in a statement.
The Weather Channel is a venture of NBCUniversal.

Sun Rings In New Year with Solar Eruption

As people around the world  rang in the New Year to celebrate Earth's latest trip around the sun Monday night, our closest star marked the occasion with some fireworks of its own — a dazzling solar eruption.
The space fireworks occurred on New Year's Eve (Dec. 31) during a four-hour eruption on the sun. NASA's Solar Dynamics Observatory captured a video of the solar event. The video shows a bright plume of super-magnetic plasma erupting from the sun's surface.
"A very nice display of solar activity — it's a New Year's Eve Ballet," SDO officials wrote in a video description posted on YouTube by the mission mascot Camilla Corona SDO, a public outreach effort.(source;space.com)
