| The astrobiologists involved with Project Viking suspect that Mars might be an inherently inhospitable environment for life. |
| As a result of the breadth of such profound scientific questions, astrobiologists draw heavily on expertise in biology, chemistry, astronomy, and planetary science. |
| It's now respectable amongst astrobiologists to consider the possibility of life in the clouds of Venus. |
| The question of whether life could have evolved on another planet has always been the big question, the Holy Grail, for astrobiologists and planetary scientists alike. |
| If so, it will boost the hopes of astrobiologists who believe Europa might also be capable of supporting some form of life. |
| One of the things astrobiologists are interested in is trying to understand the formation of organic molecules in space, in interstellar clouds and meteorites. |
