The host star hasnt been named but was identified as an M1 dwarf M dwarfs make up 70% of stars in the galaxy and are smaller than our sun Nasa astronomers found a total of five planets orbiting this unnamed host The outermost planet sits in the stars habitable zone and may have liquid water on its surface This so-called goldilocks planet is believed to be 1.1 times the size of Earth Until now, the most Earth-like planet was Kepler-62f - 1.4 times the size Details of the new star system are due to be announced later this year
The hunt for alien life has been given a boost after scientists discovered a habitable planet almost the same size as Earth.
Astronomer Thomas Barclay from Nasas Ames Research Centre in California made the discovery using data collected by the Kepler space telescope.
The unnamed planet was found orbiting an unidentified star in its so-called Goldilocks zone - a region around the star that emits just enough energy, light and temperature for liquid surface water to appear.
Mr Barclay made the announcement during the Search for Life Beyond the Solar System conference in Arizona.
Using the Kepler images, Mr Barclay said he believes he has found a new star system consisting of five planets orbiting an M1 dwarf star.
M dwarfs are stars that are much smaller and dimmer than Earths sun, and arent bright enough to be seen with the naked eye.

Or civilization succumbed to Green Politics and everyone was living in the 19th Century.....................
I did, too-I’m fond of convoluted characters. When I was a kid I read Citizen of the Galaxy several times, and I re-read Farnham’s Freehold last year, and it was still scary...
What exactly is the goldilocks zone around a dwarf star?
This doesn’t make sense.
Not too close and not too far away.................Just right................
Sign at a gym: “Remember, when the aliens arrive, they eat the fat ones first.”
A planet that close to it’s star would be fried by solar flares repeatedly. It wouldn’t be able to maintain an atmosphere.
And any civilization that could develop there would never be able to develop satellite radio. ;)
Which obviously makes it a "Class M" planet.
It basically related the mass and brightness of the star and the distance of the planet.

Interesting; I re-read it last year, too.
The opening scenes were pretty "hot", in more than the nuclear way.
It is irrelevant. We will never be able communicate.
Suppose they lived on the near side of the Andromeda galaxy, the closest. That's a 4-million-year round trip for a radio wave or laser. You gonna be here? Heck, I seriously doubt our civilization will be here.
Also, the communication equations are just impossible for a path like that. Humanity does not possess the ability to control the power required to be "heard" at those distances without integration times beyond the human lifetime. We're talking quadrillions of watts with antennas the size of a small moon, just to say "hi". I'm a communications engineer and ham radio operator, and I have had friends who have bounced a signal off the moon. The loss from the moon and back is over 230 dB. I cannot even fathom what it would be to another galaxy.
No. I think I am on pretty solid ground when I say "we" will never communicate with "them", if "they" are in another galaxy.
Hugh and Barbara certainly did make it interesting-between a lunatic, toasted wife, the temptation of his daughter’s friend, and the threat of imminent death, I understood his giving in.
Should be right next to the new Heaven.
Solid answer, backwoods-engineer. Yet, perhaps there are still unknown fractal acceleration particle forms of energy. Just sayin’, such is possible.
