Mass anomaly detected under the moon’s largest crater

Posted by in categories: materials, space

A mysterious large mass of material has been discovered beneath the largest crater in our solar system—the Moon’s South Pole-Aitken basin—and may contain metal from the asteroid that crashed into the Moon and formed the crater, according to a Baylor University study.

“Imagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground. That’s roughly how much unexpected mass we detected,” said lead author Peter B. James.

Ph.D., assistant professor of planetary geophysics in Baylor’s College of Arts & Sciences. The itself is oval-shaped, as wide as 2,000 kilometers—roughly the distance between Waco, Texas, and Washington, D.C.—and several miles deep. Despite its size, it cannot be seen from Earth because it is on the far side of the Moon.

NASA’s Juno Mission to Jupiter

Posted by in category: space

A beautiful abyss. This view of an area within a Jovian jet stream includes a vortex with an intensely dark center. Nearby, other features display bright, high altitude clouds that have puffed up into the sunlight.

I took this color-enhanced image on May 29, 2019, as I performed my 20th science flyby of Jupiter. At the time, I was about 9,200 miles (14,800 kilometers) from the planet’s cloud tops. Citizen scientists Gerald Eichstädt and Seán Doran created this image using data from the JunoCam imager. Details: https://www.missionjuno.swri.edu/news/jupiter_abyss
