With the landing success of Chang’e-4 on the far side of the Moon, China is poised to launch Chang’e-5 in late 2020. As the first part of the Chang’e Lunar Exploration Program’s (CLEP) Phase 3, the unmanned expedition is expected to transport lunar samples from the Moon back to Earth. According to China Aerospace Science ...
Eight and a half years into its grand tour of the solar system, NASA’s Voyager 2 spacecraft was ready for another encounter. It was Jan. 24, 1986, and soon it would meet the mysterious seventh planet, icy-cold Uranus. Over the next few hours, Voyager 2 flew within 50,600 miles (81,433 kilometers) of Uranus’ cloud tops, collecting ...
Using data from the Dark Energy Survey (DES), researchers have found more than 300 trans-Neptunian objects (TNOs), minor planets located in the far reaches of the solar system, including more than 100 new discoveries. Published in The Astrophysical Journal Supplement Series, the study also describes a new approach for finding similar types of objects and ...
Though it looks like it to us, clouds on Jupiter do not form a flat surface. Some of Jupiter’s clouds rise up above the surrounding cloud tops. The two bright spots in the right-center of this image are much higher than the surrounding clouds. Jupiter’s clouds extend deep into the planet Jupiter’s atmosphere is a ...
Approximately every two Earth years, when it is summer on the southern hemisphere of Mars, a window opens: Only there and only in this season can water vapor efficiently rise from the lower into the upper atmosphere. There, winds carry the rare gas to the North Pole. While part of the water vapor decays and ...
No one has a firm grasp on the dimensions and activity of the lowest part of our upper atmosphere, known as the ionospheric D region, because it’s a moving target. Located 40 to 60 miles above the Earth’s surface, the region moves up and down, depending on the time of day. And it’s nearly impossible ...
Several greenhouse gases are emitted as common plastics degrade in the environment, according to researchers from the University of Hawai’i at Mānoa School of Ocean and Earth Science and Technology(SOEST). Mass production of plastics started nearly 70 years ago, and the production rate is expected to double over the next two decades. While serving many applications because of their ...
