Of the four main elements that make up life on earth, are they present on other planets?
Question Date: 2015-11-04
Answer 1:

Hydrogen is the most common element in the universe, oxygen is third, carbon fourth, and nitrogen is seventh. They are all quite common on most planets (all but the very hottest like Mercury or Venus, which have lost most of their hydrogen). However, just because these elements exist doesn't mean that there's life.
