Scientist discovered that all the planets that are able to sustain life are yet to be born.
A new and enlightening study in the fields of astronomy and astrophysics revealed that all the planets that are similar to Earth have yet to be born across the galaxy. Earthlike planets are yet to be formed in the Milky Way.
According to the data collected by both Kepler and Hubble electronic space telescopes, scientists theorized that when Earth formed nearly 4.6 billion years ago, only about seven to eight percent of the possibly habitable planets that could ever form already existed, out there on the verges of our galaxy. Also, they also stated that compared to all planets that could virtually form and sustain life, Earth is actually very young.
In this study, published on Phys.org, researchers show that the process of star and planet creation is much slower now than it was in the distant past. They also discovered that there is so much oxygen and helium gas left in the Universe, that both star and planet creation could go on for a very long time.
Using computer generated models of the known and explored Universe, scientists have come up with some intriguing numbers. It seems that there are about one billion planets in the Milky way Galaxy that have the same properties as our planet. Extrapolating, we can infer that there can be a grand total of 100 billion galaxies in the visible Universe and each of them can have the same number of habitable planets. Sadly, according to their finds, the Milky Way has less gas available for star and planet formation.
The team points out that the advantage is still on our side. It seems that Earth’ early formation gives us the opportunity to further study and interpret the evidence left from the beginning of the Universe. They also said that, in the distant future, late coming civilizations will not be able to make such observations. Study estimates state that in about a trillion years from now, all the light and radiation emanating from the Big Bang will be erased due to the rapid expansion of space.
In other words, if there will be another civilization after us, they will be without a clue regarding how the Universe began and evolved.
Peter Behroozi, the author of this study and a member of STSCI (Space Telescope Study Science Institute) said that the purpose of this scientific endeavor was to understand Earth’s placement in the Universe.
