Are We Ever Likely To See Another Earth Type Planet?
It’s exciting times in science as we get more information around Mars and the ability to reach distant planets in our Solar System seems to be getting closer with developments of the EM drive and other thrust systems. Given that most of the habitable planets in the Universe have still to be formed after the Sun dies out in 6 Billion years or so our only opportunity to see other developed planets and potential lifeforms would mean travelling to Planets such as Kepler-186 which is 500 light years away.
What’s your thoughts on the possibility of Alien lifeforms out there and are we destined to never see them?
We were among the first 8 per cent of worlds that could potentially support life when we came into being 4.6 billion years ago, according the astronomers behind the study. Many of the other Earth-supporting planets won’t turn be around for some time — and 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 come to the conclusion. The latter was built in part to look for the kind of earth-supporting planets that could be sustaining life elsewhere in the universe.
Lead researcher Dr Peter Behroozi, from the Space Telescope Science Institute (STScI) in Baltimore, US, said: “Our main motivation was understanding the Earth’s place in the context of the rest of the universe. Compared to all the planets that will ever form in the universe, the Earth is actually quite early.”
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 civilisations. 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.
