Saturn now outnumbers Jupiter for most moons, thanks to recent work by a team of astronomers. The 20 new moons bring the ringed planet's total natural-satellite count up to 82, three more than Jupiter. Seventeen of these new discoveries have retrograde orbits, meaning they travel in the direction opposite to Saturn's rotation.

Cosmological and exoplanetary discoveries are being honored for this year's Nobel Prize in physics. Half of the award will go to Michel Mayor and Didier Queloz, who announced in 1995 that they had found the first-known planet outside the solar system. The other half goes to James Peebles for his theoretical work in physical cosmology, or the field of astronomy that looks at the universe's birth and evolution.

The first person ever to perform a spacewalk has died, according to a Friday (Oct. 11) announcement from Russia's space agency Roscosmos. Alexei Leonov conducted the historic extravehicular procedure on March 18, 1965 as part of the Soviet Union's Voskhod 2 mission. Russian news agency ITAR-Tass reported that Leonov died in Moscow after battling a long illness.

NASA chief Jim Bridenstine was irked by SpaceX CEO Elon Musk unveiling the new prototype for his Mars-bound Starship vehicle two weeks ago (Sept. 28) because the company's collaboration with NASA ⁠— the low-Earth orbit project Crew Dragon ⁠— is behind schedule. Although a tweet from Bridenstine on Oct. 3 suggests the two men have reconciled over a phone call, Bridenstine commented on CNN days earlier that he wasn't convinced Crew Dragon would be ready in the three-to-four month timeline given by Musk.

NASA is asking for industry feedback on how to improve its new lunar spacesuit, the Exploration Extravehicular Mobility Unit (xEMU). The first few suits will be made at NASA and tested on the International Space Station in 2023. But the space agency wants to get feedback from the private sector on how they might, for example, produce new threads and maintain toolkits for moonwalks.

Meat has been grown in space for the first time, according to an announcement on Monday (Oct. 7) from the Israeli food company Aleph Farms. Their experiment onboard the International Space Station produced this result and was possible through a collaboration between Aleph Farms, the Russian company 3D Bioprinting Solutions and two U.S.-based food companies.

India's Chandrayaan-2 lunar orbiter has beamed back its first science data. The mission, run by the Indian Space Research Organisation, carries eight different instruments and scientists are currently analyzing imagery taken by the orbiter and data from CLASS, or Chandrayaan-2 Large Area Soft X-ray Spectrometer. CLASS helps researchers find out where certain elements are located on the lunar surface and can also observe the environment around Earth.

UFOs appear over Chile

Seven objects dropped from the sky over the city of Dalcahue on the Chilean island of Chiloé, but no one is certain what they were. The unidentified flying objects were seen tumbling down as fireballs on Sept. 25, and three days later, geologists said none of the objects' landing sites contained traces of meteorite. Space junk have been the culprit, but one expert saw no obvious space debris candidates that could have rained down over Dalcahue.

On Thursday (Oct. 10), NASA's ICON mission launched into space from Cape Canaveral Air Force Station aboard a Northrop Grumman Pegasus XL rocket, which was released in midair by its carrier plane, a Stargazer L-1011. ICON, or Ionospheric Connection Explorer, is designed to study Earth's ionosphere and how this massive layer of the atmosphere is linked to terrestrial weather and space weather.
