Can This Planet Inhabited by Aliens or even Human?

Earth Planet that has the Potential to Live in

IZOKE - Astronomers have recently discovered three new planets that resemble Earth, and they predict that signs of alien life will soon emerge from these planets.

Earth and Alien

Scientists also look at the planet in a little different, because the fact of these planets do not orbit the sun, or any other star so its orbit. Instead, they are crowded into an orbit around a dwarf star around the Milky Way, which is 40 light years from our galaxy.

Strange Planet

Reporting from Tech Insider citing the inventors of this planet, this planet has the potential to be habitable.

"This is the first Earth-sized planet that has the potential to live in," said astrophysicist and one of the inventors of this planet, Michael Gillon. He also added that he and his team were very surprised to find such a planet at a great distance from Earth.

Gillion and colleagues, who publish their findings du journal Nature, found the 'trio' of this planet with a telescope called transiting Planets and Small planetesimals Telescope, or Trappist located in La Silla, Chile.

This planet was discovered when the planets pass between tiny star into orbit, and the Earth. This makes these three planets emit faint light signal that can be captured by the telescope.

The question is now, what are the requirements that make a planet habitable? Here's his review in the context of the three newly discovered planet is.

3 Planet Strange

Although the distance is not too far from our galaxy, the planet turned out the third mechanism is far different from the Earth and other planets in our galaxy. These three planets circling a star called Trappist-1, which was given the name of a telescope caught. Center is only by Jupiter's orbit, which makes it much smaller than the sun.

This star was not bright and shining like the sun. Fitness orbit is actually touted as a brown dwarf star, because it radiates a lot of infrared light. This infrared frequency slightly higher than can be seen of men. Even technically, this star is not a star, because he just made up of gas.

Goldilocks Zone

Goldilocks Zone

According to astrophysicists, if we stand on the surface of the planet, dramatic red sky we will see beautifully.

Livable? Wait a minute.

On this planet, the sun will appear larger because the planet is very close to the star that became the center of their orbit. If the Earth takes a year to orbit the sun, the new planet is only takes one and a half days. Meanwhile, two other planets are located slightly further away, it took 2.4 days to evolve.

Can imagine one year only reached within a few hours?

Another difference is the 'sun' so stunted that they orbit the center turned out thousands of kelvins much cooler than the sun. This makes the planet is not at all hot.

'Goldilocks' Zone

The inventor of the three new planets, strongly believes there are at least two of the planet's habitable zone, or so-called 'Goldilocks.'

To get the criteria as the Goldilocks zone, a planet must be sufficiently light, not too much nor little. This would make the planet is a planet that is right for their water.

Two of the three planets are almost positive has all the criteria for a livable life. While the third and farthest planet from orbit center, is considered too cold and it was unclear how much time it takes to complete the orbit.

The third planet is estimated the size of Earth and Venus, and had a solid, rocky surface. But the weakness of this planet is the planet experienced a 'tidal lock,' ie, there is one side will always be facing the sun and one side is not. It makes no edge will always lunch and one side will always night.

Another drawback, and that is a vital aspect to a planet that wants to live in, is the atmosphere. Scientists and astrophysicists do not understand the composition of the atmosphere on the planet. So far, in the Milky Way, only Earth has the atmosphere with the composition enables humans, plants, and animals can live.

Alien

The composition of a planet is habitable, but the atmosphere is still a mystery it can make a planet that has livability though, will not be able to live a human. Man is not going meninggali the planet in the near future. But perhaps this was the 'anchor' of aliens.

In your opinion, can this planet inhabited by aliens or even human?
