-- this week that's creating quite a buzz as we continued to ponder the question could life exist on planets beyond earth.
Scientists have discovered a new earth like planet capable of -- water and eventually sustain life.
It's been nicknamed the goldilocks planet because.
It's not too hot not -- coal.
He tells more about this and even discovery is Alan Boss an astronomer with the Carnegie Institution -- -- He's also the author of the crowded universe the search.
For living plant and it's great to have you here today.
Did to me in a very exciting discovery an answer to huge space enthusiasts first of all but the fact that you really believe we have a plan it.
That can actually sustain life.
At this point and could actually have liquid water tells more about.
The plan it was just discovered and announced this last week and that's what is the sixth -- in the system so this planet has a whole range of plants.
The system has.
Roughly six -- some of them as low -- is perhaps twice the mass of earth some as large as sixteen times amounts of the -- the new and it's just been found it just right this -- to have liquid water.
As roughly three or four times of mass of the earth we don't know for sure it's rocky but most likely it's -- rocky planet.
And since -- at the right distance to have liquid water probably can have a rain which is just wonderful.
Considering that we -- East Coast and suffering from -- last couple of days you know rain is important for life for the first time astronomers have found out of hundreds of planets found so far.
-- which has the right distance to possibly have liquid water.
And this -- is twenty light years away which means it's not really close but.
Using today's technology how long would actually -- was to travel to that point yeah.
And what we have today would be wonderful Richard Branson could fly somewhere but it don't take a little bit of time to do that impartially at the speed of our fastest NASA spacecraft such as the new horizons mission which is on its way -- to Pluto.
I would take roughly 500000 years to get there are so it's not really something you wanna go on and of course 500000 years -- -- you didn't wanna stay there so the best way to.
Learn more about this plan is look at the -- which really takes twenty years.
Effect a couple years back a Russian scientists sent a message to this planet.
This whole system because other plans have been found here as of 2007.
And so we've already are trying to communicate with possible life forms that might be in the -- 581 system.
It is called with a funny one by the UPS of all things named after his finest called police who first as catalog the -- many years ago.
Fascinating and then you've got you've been following this planet have been talking about the last twelve years and it's been very interesting to follow its progress but how are you able to determine that it can actually sustain life.
And have water knowing that we don't have a telescope yet built that can actually see it.
Right we're only detecting this planet indirectly -- watching the wobbled with the just produced by the plants pulling on the Starr watching the star while on the center of mass.
But the very simple calculation do we know how bright the stars it's roughly -- 1100 as bright as our side.
And that means that we can also figure -- how hot you would be if -- really given distance from us on and we can.
Knowing that period of which the star wobbles -- -- the planet which is roughly.
Every 37 days that means the planet as the distance roughly ten times closer to a star than -- -- -- -- this.
And since the sun is roughly hundred times.
Less bright that means that we actually have about the same amount of sunlight hitting us on that planet as we -- on earth and that means we are right in the smack down what's called habitable zone.
Where liquid water could exist so it's it's a much closer and the stars fainter.
But those two factors combined to say it's just the right temperature -- be -- the goldilocks planet where water could do it.
And really quickly few seconds what do you think this is going to do the ramifications scientifically and spiritually what do you think people can come away with.
We are certainly on the verge of learning if there -- life elsewhere in the solicited ought not only the forces to but I'll be on.
The real -- go for mass will be to come up with a way of building a space telescope -- actually -- assistant told that actually has life on it now.
It's very very interesting discovery and I know that when you're excited about some other sciences so thank you so much for sharing insights -- -- -- to.
And further discoveries that may Connolly said -- --
