New "earth" found

ASTRONOMERS have found a "new Earth" - the first planet outside our solar system with the potential for life as we know it.

The Earth-like planet is 20.5 light years away, orbiting the "red dwarf" star Gliese 581 in the constellation Libra.

It is one of three planets in that solar system, with the Earth-like planet named Gliese 581C.

Commenting on the discovery by a team of European scientists, University of Adelaide Professor Roger Clay said this was the first time a planet with a mass or weight similar to the Earth's had been found.

"They believe that its distance from the star would mean the surface temperature is not that different to the surface temperature of Earth," he said.

This meant water would be in a liquid form.

"So, potentially, it is the sort of place that you'd start looking to find some sort of life form... it does seem to have the right ingredients."

The discovery, at the European Southern Observatory's telescope in La Silla, Chile, was made using spectroscopy.

The technique is based on the principle that light is shifted more towards the blue end of the spectrum when something is moving towards you and more towards red when it is moving away, Professor Clay said.

It worked in this case because the planet has a tight orbit and the star was relatively lightweight, so movement was easier to detect. The discovery appears to confirm suspicions of astronomers that the universe has many Earth-like worlds.

The new planet is about 1 1/2 times the diameter of the Earth. It is the first exoplanet (a planet orbiting a star other than our own Sun) that is like our Earth. Of the 220 or so exoplanets found to date, most have either been too big, made of gas rather than solid material, far too hot, or far too cold for life to survive. "On the treasure map of the universe, one would be tempted to mark this planet with an X," said Xavier Delfosse, one of the scientists who discovered the planet.

"Because of its temperature and relative proximity, this planet will most probably be a very important target of the future space missions dedicated to the search for extraterrestrial life."

they think its between 0 and 40 degrees C

 

so we could well live over there...

 

gravity might be a bit of a prob but who cares if you can fly? doesn everyone wish they could?

 

im gonna be the President of the New Earth..

 

No emos or newbies allowed.. ill add stuff as i see fit..

Wait, 20 light years.

Can we go at half the speed of light in the vacuum of space?

Dunno.

 

One Light year is the distance light travles in a vacuum in one year.

Light travels at 186,282.397 miles per second.

Over a year this distance is 5,879,000,000,000 miles.

 

So, to answer question we can not travel 93,141.2 miles per second in a vacuum.:cool:

We will never make it to Earth 2.
