Earth was one of the universe’s first habitable planets, and we’re likely to miss chance to meet future alien civilizations, study claims
Earth was one of the first habitable planets in the universe, according to a new study.
Earth was among the first 8 percent of worlds that could potentially support life when we came into being 4 point 6 billion years ago. Many of the other Earth like planets will not be around for some time. New Earth-like planets are likely to come about after our own sun burns out in six billion years.
Astronomers looked at data from the Hubble and Kepler space telescopes to reach this conclusion. Humanity arrived early enough to be able to see back into the beginnings of the universe with telescopes like Hubble and other equipment.
But that same understanding might be off-limits to future civilizations. Because the universe is expanding so fast, any observable evidence of its beginnings is likely to be erased — leaving people in the future with no clue about how the universe got to where they are.
Galaxy observations show that 10 billion years ago stars were forming rapidly, but the process used only a fraction of all the hydrogen and helium in the universe.
Today, stars are being born at a much slower rate and, with the amount of raw material still available are likely to continue being created for a very long time to come.
Kepler had shown that Earth-sized planets occupying “habitable zones” are common in our galaxy.
Scientists estimate there could be one billion Earth-sized worlds in the Milky Way, a large proportion of which are rocky
The last star is not expected to burn out until 100 trillion years from now, providing time for untold numbers of potentially life-sustaining Earth-like planets to form in habitable zones.
Even though Earth is older than other, newer planets in the universe, some planets are much older than Earth, and may already have advanced civilizations. The oldest planets found yet by astronomers are almost 13 billion years old. Whether any of these contain life is unknown, however based on the sheer number of planets, there is a good possibility that there are other life forms out there.
