Two of Arizona’s most famous landmarks may be linked by cosmic violence: the asteroid that gouged out Meteor Crater may have also caused the formation of an ancient lake in the Grand Canyon. This surprising connection between Arizona’s world-renowned geological features stretches back 56,000 years, to when a 300,000 ton nickel-iron asteroid slammed into the Colorado Plateau with the force …

When lightning struck on 4 July along the remote North Rim of Grand Canyon national park, sparking a small wildfire in a patch of dry forest, few predicted the terror and loss that lay ahead. Fire managers decided that conditions seemed ideal to let the blaze burn at a low intensity – a practice known as “control and contain” that …

A meteorite impact thousands of years ago may have triggered a landslide in the Grand Canyon and reshaped the Colorado River that runs through the national park. Geologists studying driftwood and lake sediments found in Stanton’s Cave — in Marble Canyon, which lies in the eastern part of the Grand Canyon — revealed a possible connection between the area and …

The ancient meteor impact that formed Arizona’s Barringer Crater sent shock waves through the Grand Canyon — likely triggering a landslide that dammed the Colorado River, a new study suggests. Barringer Crater, also called Meteor Crater, formed between 53,000 and 63,000 years ago, when a giant cosmic “curveball” punched a hole in Earth’s surface. The force of the impact traveled …

WASHTENAW COUNTY, Mich. – Health officials said mosquitoes that were collected in Washtenaw County have tested positive for Jamestown Canyon virus. The Washtenaw County Health Department collected a sample of a mosquito pool on June 12 in the Whitmore Lake area and received the results in July. There have been no human cases reported in Washtenaw County or in Michigan …

On July 15, a solar filament erupted from the Sun’s upper left side, ejecting a powerful blast of plasma and magnetic fields into space. The resulting explosion was so massive that it seared a deep, fiery scar of hot plasma and debris onto the star’s visible surface. While filament eruptions aren’t uncommon, astronomers had already been watching an unusually large …

On July 15, a colossal filament erupted from the sun’s northeastern limb, dramatically reshaping part of our star’s surface, albeit briefly, and unleashing a coronal mass ejection (CME) into space. The outburst was so powerful that it carved a glowing trench of hot plasma more than 250,000 miles (about 400,000 kilometers) long, roughly the distance from Earth to the moon. …
