Juno to get up-close look at Jupiter's Great Red Spot

Tonight, NASA's Juno spacecraft will fly over Jupiter's Great Red Spot, giving scientists an "up-close and personal" view of the storm which has been raging on the planet's surface for at least 180 years, according to NASA.

Why it matters: This will be Juno's sixth flyby over the planet's clouds; it's expected to be approximately 5,600 miles above the Great Red Spot when it makes its closest pass at 10:06 p.m. ET. Scott Bolton, Principal Investigator of Juno at the Southwest Research Institute in San Antonio, told NASA Juno "will dive in to see how deep the roots of this storm go, and help us understand how this giant storm works and what makes it so special."

Six-year journey: Juno was launched in August 2011 and was in Jupiter's orbit for exactly a year as of July 4, logging 71 million miles around the planet.

South Korea and Italy see spikes in coronavirus cases

Data: The Center for Systems Science and Engineering at Johns Hopkins, the CDC, and China's Health Ministry. Note: China numbers are for the mainland only and U.S. numbers include repatriated citizens.

The novel coronavirus has spread to more nations, and the U.S. reports a doubling of its confirmed cases to 34 — while noting these are mostly due to repatriated citizens, emphasizing there's no "community spread" yet in the United States.

The big picture: COVID-19 has now killed at least 2,446 people and infected almost 79,000 others, mostly in mainland China. New countries to announce infections recently include Israel and Lebanon, while Iran reported its sixth death from the virus. South Korea's confirmed cases jumped from 204 Friday to 433 on Saturday and Italy's case count rose from 3 to 62 by Saturday.

Antarctica's Eagle Island now has a side that's almost ice-free following this month's searing heat wave in the region, images released by NASA show.

Why it maters: "The warm spell caused widespread melting on nearby glaciers," NASA said in its report. It's the third major melt event of the 2019-2020 Southern Hemisphere summer, following warm spells in January and last November, according to the United Nation's World Meteorological Organization (WMO).
