   Could alien life be different to our own?

   • For instance, consider the under-ice oceans of Europa and Ganymede (two of Jupiter 's large moons): these are places where the temperature is just right, there is access to water and to minerals, too. Then again, that's viewing things with a very Earth-like lens, and of course alien life could be very different to our own.

   Do we have life on other planets?

   • So far we have no direct evidence of life on other planets. But I believe that we are probably not alone. And it’s not speculative at all. We already know that half of all sun-like stars have an Earth-like planet orbiting at roughly the same distance from the star.

   Jun 16, 2021 · Rebecca Allen, space technology expert: Yes, but they probably don't look like us.
