Hydrothermal vents on the seafloor support a rich diversity of life, and they contain deposits of valuable metals used in the manufacture of lithium ion batteries. A new research paper looks at what is known about the vital microscopic life in these locations to evaluate the possible impacts of mining these and other deep-sea locations.

A new class of astronauts will graduate basic training on Jan. 10, 2020. They will join the active astronaut corps, beginning careers in exploration that may take them to the International Space Station, on missions to the Moon under the Artemis program, or someday, Mars. The 2017 class includes (top row) Matthew Dominick of NASA, Kayla Barron of NASA, Warren Hoburg of NASA, and Joshua Kutryk of CSA, (middle row) Bob Hines of NASA, Frank Rubio of NASA, Jennifer Sidey-Gibbons of CSA, Jasmin Moghbeli of NASA, and Jessica Watkins of NASA, (bottom row) Raja Chari of NASA, Jonny Kim of NASA, Zena Cardman of NASA, and Loral O’Hara of NASA.

A large tidewater glacier meets the coast in west Greenland, spilling ice and meltwater into the ocean. The Intergovernmental Panel on Climate Change (IPCC) special report on the ocean and cryosphere in Sept. 2019 highlighted how climate change is affecting the planet’s ice and oceans.
