Scientists have found 20 never-before-seen moons orbiting Saturn, making it the planet with the most known moons in our solar system.

Why it matters: The newfound natural satellites increase Saturn's moon count to 82, eclipsing Jupiter's 79 known moons.

Details: The new moons are each about 3 miles across, and 17 of them orbit the ringed planet in retrograde — going the opposite direction of Saturn's rotation, according to an announcement from Carnegie Science.

  • Those 17 retrograde moons take more than 3 years to orbit the planet and are thought to be the remnants of a larger moon that broke apart in the past.

Go deeper: Enter a contest to help name the newly discovered moons from now until Dec. 6.

Protests over the death of George Floyd and other police-related killings of black men spread across the U.S. Saturday, amid tense standoffs with police in several cities.

The big picture: Floyd's fatal run-in with police is the latest reminder of the disparities between black and white communities in the U.S. and comes as African Americans grapple with higher death rates from the coronavirus and higher unemployment from trying to stem its spread.

Major U.S. cities have implemented curfews and called on National Guard to mobilize as thousands of demonstrators gather across the nation to continue protesting the death of George Floyd.

The state of play: Hundreds have already been arrested as tensions continue to rise between protesters and local governments. Protesters are setting police cars on fire as freeways remain blocked and windows are shattered, per the Washington Post. Law enforcement officials are using tear gas and rubber bullets to try to disperse crowds and send protesters home.

President Trump told reporters on Saturday evening he would postpone the G7 summit to September and expand the meeting to more nations that are not members of the Group of 7.

Details: Trump said he would invite Russia, South Korea, Australia and India to the summit, according to a pool report. "I don’t feel that as a G7 it properly represents what’s going on in the world. It’s a very outdated group of countries," he said.
