Today’s (March 21) Google Doodle honors the Mexican astronomer Guillermo Haro, who would have been 105 today.

His signature discovery was the Herbig-Haro object, a celestial phenomenon named after Haro and the American astronomer George Herbig, who was researching the same occurrences at around the same time.

Herbig-Haro objects are jets of gas and other matter erupting from newly formed stars which collide with the gas and dust around them at the speed of several hundreds of kilometers a second.

Scientists propose reflecting sun’s rays with salt.

USGS scientists and park staff stress that there’s nothing to worry about in terms of the supervolcano underlying Yellowstone.

“We have zero concerns that anything is happening volcanically,” Stovall said, adding that there hasn’t been a Yellowstone supervolcano eruption in more than 600,000 years. “There’s been geysers erupting through that whole time and that doesn’t mean that anything is happening with magma underground.”

Volcanic activity on Vanuatu’s Ambae island has picked up again, with fresh ashfall reported across the island’s west and south.
