“There is an entire ecosystem that lives within sea ice in polar regions that might be an analog for what’s happening on other [worlds],” says Kevin Arrigo in an article about how extraterrestrial oceans could support life.

"It's not a surprise that no one would support Yucca," says Stanford's Rodney Ewing, who led a 2018 study that recommended moving responsibility for disposing of nuclear waste to an independent nonprofit corporation.
