Scientists are looking for planets which could be habitable. Based on their analysis, just eight per cent of planets that would be capable of hosting life have been formed.
After studying data collected by Nasa’s Hubble Telescope and the Kepler space observatory scientists from the Space Telescope Science Institute (STScI) in Baltimore were able to determine the remaining material from the Big Bang that could create habitable planets, and found that there is 92 per cent of said material.
Peter Behroozi of STScI said “Compared to all the planets that will ever form in the universe, the Earth is actually quite early.”
The Hubble telescope has given astronomers the chance to map star formation within the universe, which shows that it is still creating stars and that just a fraction of the helium and hydrogen to make these has so far been used.
According to their survey, their are around 1 billion habitable planets in our Milky Way alone – which was formed just 2 billion years after the Big Bang.
