Using NASA mathematical models and satellite observations of sand, sea salt and smoke moving across the Western hemisphere, researchers at Goddard Space Flight Center created this visualization of the 2017 hurricane season.

What you're seeing: Sand and dust from the Sahara (seen in brown), sea salt picked up by the winds of hurricanes Irma, Harvey, Jose and Maria (blue) and smoke from wildfires in the western U.S. (gray) travel thousands of miles on wind. Across the Atlantic, Hurricane Ophelia takes form off the coast of Africa.

Why it matters: Simulating currents — in this case, from July 31, 2017 to November 1, 2017 — can be used to better understand the conditions under which storms form and evolve.

Driving the news: Murkowski said on Thursday that she supported former defense secretary James Mattis' condemnation of Trump over his response to protests in the wake of George Floyd's killing. She described Mattis' statement as "true, honest, necessary and overdue," Politico's Andrew Desiderio reports.

Over the course of just a few hours, President Trump was rebuffed by the Secretary of Defense over his call for troops in the streets and accused by James Mattis, his former Pentagon chief, of trampling the Constitution for political gain.

Why it matters: Current and former leaders of the U.S. military are drawing a line over Trump's demand for a militarized response to the protests and unrest that have swept the country over the killing of George Floyd by police.
