Lauren's Science Corner: Circumhorizontal ArcViewers in western Wisconsin today observed a unique atmospheric phenomenon: a circumhorizontal arc! Casually called a 'fire rainbow,' it occurs in summer-time as the sun must be high in the sky, at an angle of 58 degrees or higher.
Lauren's Science Corner: Minnesota May TornadoesYou could say that May opens the door to tornado season in Minnesota, yet the month only experiences five tornadoes on average annually. Thus, for eight tornadoes to impact the state in one day is on the rarer side.
Lauren's Science Corner: Aurora EditionA severe geomagnetic storm ignited an epic outbreak of the aurora borealis across northern latitudes world-wide over the last two nights!
Lauren's Science Corner: Beware The Pizzly!The bloodline of one of nature’s most powerful and fascinating land-bound apex predators is merging with an animal atop the Arctic food chain, the polar bear—yielding a fearsome hybrid referred to as the “pizzly” or “grolar” bear. The breeding of these king creatures is likely the result of habitat overlap caused by global climate change.
Lauren's Science Corner: Numbingly Cold NovemberAhhh, September 2014; six days spent soaking up 80° highs and 12 days in the 70s. October 2014 followed and offered up plentiful 60° days as well. And then came November.
Lauren's Science Corner: Climate Change Increasing Lightning Strikes?There are 1.4 billion lightning strikes globally each year -- 25 million of those bolts occur in the U.S., and that number may be going way up. A study, recently published in the journal Science, concludes that a 50 percent increase in lightning strike frequency is possible by the end of the century.
Lauren’s Science Corner: The Return Of The Hole Punch CloudOn Saturday, Nov. 1, WCCO-TV viewers in the Twin Cities metro, and all the way to Houston in far-southeastern Minnesota, spotted a rare and mesmerizing sight, the hole punch or fall-streak cloud.
Lauren's Science Corner: The International Space StationWhat is the size of a football field, has a gym, and the best view in our solar system? The International Space Station is an orbiting laboratory or habitable artificial satellite (fancy!) and serves as a space port for a myriad of multi-national spacecraft.
Lauren's Science Corner: Total Lunar EclipseAre you totally excited for the total lunar eclipse early Wednesday morning?! The eclipse will be viewable across North America. And with clear skies to prevail over Minnesota and Wisconsin, all will behold the astronomical awesome-ness!
Lauren's Science Corner: Lava, Lahars, and Magma, Oh My!On Friday, the Big Island of Hawaii declared a state of emergency as lava flows from the Kilauea volcano threatened a residential area. Mount Kilauea has been constantly erupting since 1983, yet in late-June new vents, cracks in the Earth’s surface through which lava erupts, opened on the volcano’s north-eastern flank.
Lauren's Science Corner: What Moves The 'Sailing Stones' Of Death Valley?Since the 1940's, scientists and visitors to Death Valley National Park have marveled at and pondered the mystery of its 'sailing stones.' Hundreds of rocks from pebble to boulder-size plow their way across the flat surface of the 'Racetrack playa,' engraving trails, some of which are considerable length, in the dry mud landscape.
Lauren's Science Corner: Hole Punch CloudsNo, it’s not a UFO or the onset of the apocalypse…it’s a hole punch cloud, an usual and mysterious sight to witness. Hole punch clouds, which are also called canal clouds, were spotted in the skies over the Twin Cities on Sunday and again Tuesday. WCCO-TV viewers in Minneapolis, Blaine, Chaska, and Mahtomedi captured photos of this rare and intriguing phenomenon.
