Earth has captured a new mini-moon that will orbit our planet for a few months before heading back out on its cosmic journey through the solar system.

The big picture: Scientists think our planet likely has some kind of "mini-moon" in orbit at any given time.

The plumes seen erupting from Jupiter's moon Europa might be fed by water trapped in the world's crust, according to a new study.

Why it matters: Europa is thought to be one of the best places to hunt for life in the solar system, in part because of the subsurface ocean scientists expect exists beneath its icy crust.

China and the U.S. don't collaborate in space —a decades-old divide that is shaping the future of both nations' space programs.

Why it matters: U.S. semiconductor companies and those in other sectors are under pressure — from politicians and consumers — to become less reliant on China. The record of the nations' parallel ambitions in space shows what the U.S. gains and loses when it cuts China off.

Hurricane Iota made landfall in Nicaragua late Monday as an "extremely dangerous" Category 4 storm, packing maximum sustained winds of 155 mph, per the National Hurricane Center.

Why it matters: The storm is the most powerful of the 2020 Atlantic hurricane season, with "life-threatening storm surge, catastrophic winds, flash flooding, and landslides expected across portions of Central America," the NHC said.

The International Space Station has four new crewmembers delivered to the orbiting outpost care of SpaceX.

Why it matters: This mission marks the first fully operational flight of the Crew Dragon and ushers in a new era of regular, human missions to orbit operated by SpaceX for NASA.
