Here on Earth, liquid water is key to life. But elsewhere? That might not be the case. A new study suggests that other liquids might be able to support life on worlds beyond our own.
"We consider water to be required for life because that is what's needed for Earth life. But if we look at a more general definition, we see that what we need is a liquid in which metabolism for life can take place," study leader Rachana Agrawal, a postdoctoral student at the Massachusetts Institute of Technology (MIT), said in a statement.
