Their finding is important from the perspective of meteorites and other space rocks that crash on Earth. Many scientists think such objects could once have seeded our planet … Read more
A new study published in the online journal Life says a hotter, pressurized form of carbon dioxide could harbor life in a similar way water does on Earth. This is an interesting find, theoretical though it is, because it might obviate the need for water to be present for life to exist on other planets. In fact, of … Read more
