Earth’s Twin: Won’t Support Life

Two planets which are similar in size to our Earth has been spotted orbiting a star that is also similar to our Sun. This has been the first time another planet has been seen in another solar system that has similarities of the planet we call home, if one planet discovery was not enough a second was also spotted which reveals that somewhere there could be a planet that supports life and if discovered plans will be put into placed to get humans to it.

Kepler-20f and Kepler-20e

The first planet that has been discovered is one being called Kepler-20f, this is a location which is much like earth but signs are that it has a much thicker water-vapour atmosphere. Moreover, the surface is looking as if it would be too hot to support life.

The second planet named Kepler-20e is a little smaller in size compared with earth but it is much hotter again ending hopes that life could exist on the planet. Could these planets be giving us a glimpse into the future of earth, there is the huge debate of global warming and the rise of temperature will cause massive consequences in regards to natural disasters.

As such could these planets show us our future as earth heats up, although nobody has made any suggestions this is a possibility and a worrying one at that.

Both the newly discovered worlds are circling a parent star in a tight orbit, which has been measured to last just nine for Kepler-20f and sixteen days for Kepler-20e. Earth in comparison takes 365 days to orbit the sun and with it has four distinct seasons which are experienced almost everywhere, on these planets who knows if there are seasons but if they are then they won’t last long.

For scientists who are watching the skies intently this a major discovery, and it will be in 10 years time or 100 years time that people will look back and ask when the first Earth-sized planet was found. However, this will fall into the background if scientists actually do discover a planet that actually supports life.

1000 light years away

Visiting these planets is not really in the cards at the moment as Kepler-20e, for example, is the best part of 1000 light years away.

The other problem as mentioned before is that both are too hot to allow for life and this means that man would struggle to enter the atmospheres of these planets without developments in technology that could support that, this is provided the 1000 light year bridge can be traversed.
