Astronomers Find First Earth-like Planet in Habitable Zone

[nowhere991]

I hope that satelites that was projected to photo universe crashes into Gliese and stirs trouble. And draw flys to invite into our universe as a threat by following our satelite. We need to fight the universe because we wanted to know as aggressors and I hope they come as predators so they can EAT us and grow & raise us as their food chain.

[kodiak1966]

Unless they actually see a new planet, THEY HAVE NOT FOUND A NEW PLANET! All hogwosh! They say if a star seems to be pulled by gravity,that it must be a planet!All theory and no proof.Get a deep space telescope set up around or past Jupiter and maybe we will see some new planets.Until then..all speculation.

Do not only think that life is all there may be in the universe. It is very easy to become trapped in the thinking that we are used to by what we percieve to be existence. what if there is something else other than just life. something we are not able to no about or comprehend as the something else out there is not life as we no it.

ok what i do?

[dryalex12]

funny how im a Libra and its in Libra

[voltlord]

same!

[domco2525]

Shut the fuck up. No real scientist cares about how you're oriented with the zodiac. That's all bullshit.

[metaldave08096]

I was watching an episode of the universe and they stated that the planet was more like venus than it is the earth. That sucks!!!! No life there I guess....

[Stillahills]

1 light year is roughly 6 trillion miles.

[A1var3z360]

how many regular years is 1 light year???

[TheSNCvideos]

a light year is a distance not a time mate. 1 light year is the distance you would have gone if you spent 1 year travelling at the speed of light(300,000,000metres per second)

[LilLaura86]

actually a light year can be compared to regular time known as Julian time, the unit measurement of time utilized by Western Civilisation ( 365 days). So one light year is actually some 10 trillion km in distance put simply, but it is also the distance that light can travel in one Earth/Julian year.

[Bozewani]

it is obvious it is a rocky planet, what is not obvious wether it has water.

[taratarajing]

its interesting because its only 20 lightyears away...so we are actually seing it 20 years ago...compare 2 d other planets that are hundreds of lightyears away, studying d 20 years ago is much much better than studying 100 or 200 years ago...

[verbakes88]

isnt a light year a unit of distance? how are we seeing it as it is 20 years ago?

[stevebd1]

Because it's taken the light 20 years to reach us so the image that reaches us is 20 years old. The image we see of the Sun is as it was ~8.3 minutes previous, the image of the moon, as it was ~1.3 seconds previous due to the finite velocity of light.

[duckfetzer]

how do you know the light took 20 years to get here? a lightyear is a unit of distance not time

[stevebd1]

and what do you think that unit of distance is based on.

[S8T8E8A]

think of it this way: 1 light year is the distance that light travels in 1 year. That distance is roughly 10 trillion kilometers. So if the point that the light started from is 20 light years away (200 trillion km), it would take that light 20 years to reach us. Like if you left your house to go somewhere that's 40 km away, and you were traveling at 40 km/h, you'd get there in 1 hour right?

[mrcraig41]

Another shining example of some dim-witted NITWIT incapable of thinking beyond their own doorstep ;) I also thought that there was no such thing as a dumb question! You sure blew the lid off

of that one, professor!

[austincmcm]

@duckfetzer LAugh MA OFF! A light year is how far light travels in a year, 20 light years away means that it takes 20 years for the light to travel to us. Laugh OL

[AyKay47]

@duckfetzer actually I believe a light year is the time on how long the light took to travel to our vision. Meaning it's actually a measurement of time. Most anything we do is the same thing, and rather it being a measurement of distance it becomes a measurement of light, but how long that light takes to get here in years. So it's a measure or time since light gives us the illusion of time. Maybe i'm completely wrong, oh well.

[johnqp777]

@duckfetzer

You dumbass! A light year is the time it takes for light to travel in one year. So, if it's 20 light years away it take 20 YEARS TO GET HERE!

[taratarajing]

yes lightyears is a measurement for distance...but its also a measurement for time...lightyears actually means "the distance light travels in one year". if the star is 20 lightyears away, the light it emmitted will take 20 yrs to reach us(earth). so if we look at this star today(tonight) we are actually seeing the light it emmited 20 yrs ago...peace!!!

[goferbut]

And, thi planet is like... a red dwarf right? Arn't those like just about to explode? Wouldn't thsat be bad for the life on the other planet if there is life there?

[Boy75402]

The planet orbits a red dwarf. A red dwarf star isn't about to explode. For a star to explode, it's got to be around 3 times heavier than our sun. Red dwarfs, however, are only 1/3 as heavy as our sun.

Red dwarfs live a lot longer than our sun though, and when they die, they'll just dim out, instead of explode.

[ORACLE063]

red dwarves last longer than main sequence stars as well

[reluctantprophet7]

my bad.. it's at 2:37. Also... the pyramid shape on the other side of it when the planet rotates

[orion1077]

Didn't you pay attention to the description of the detection method?

They cannot even see the planet...they detect it by "indirect methods" like the spectrum shift. This means they can see what the planet does to the sun (it orbits)...SO they have NO IDEA WHAT THE SURFACE LOOKS LIKE...The appearance of the surface here is just CG(computer graphics).

[yiotos]

CGI.

[reluctantprophet7]

At 4:38 does anyone else see a skull??? bd sign... don't go... To Serve Man... or somethin'....

[TheSkyLorde]

We can´t. just by radio sounds we can touch with that planet...

[marcelosinico]

How do we get there?

[lillukepossy]

and also, because it is so close, Gliese 581 may just very well domonate the sky and be the only view for the life there, if there is life, they would most likely not have sight because there would be a certain amount of adapttation to the envirement there, which will make it hopeless that there will ever be any intelegent life forms on that planet?, owell, if there is life on this planet it is a majot step foward in science and astromany, and the understanding of the universe.

[lillukepossy]

i have done alot of study on this planet myself, and i am rather exited about the future outcome, it is a hopeable candidate, and the fact that it may realm water exites me even more, could we be gazing at a planet which gazes back at us? :D

i think that endofsociety makes a point, i no that it is 14 times closer to earth to its sone which makes up for the loss in heat, but could being this close to such a bright light maybe burn life if the atmosphere cant withstand it gamma rays?

[endofsociety]

Anyone ever wonder what effects a RED Dwarf star may have on us Earthlings? Being that it is different from our Yellow Sun which is much more massive. That still shouldn`t stop us from trying though.

[FatalFist]

For one apparently some sort of force would alter the revolution orbit by pushing Earth back. Other than that, it's temperature increases do to burning more fuel more rapidly and the expansion getting us closer to the Sun itself would cause Earth to accumulate more heat. Simply put... you'd see the ocean evaporate very quickly just before bursting into ash :P

[FatalFist]

Bah nm ignore me, I'm thinking Red Giant and the process it under goes as it changes.

[ubentu]

Something I've noticed, we always seem to discover stars systems with very close orbiting planets. Does anyone think that the elongated winter/ summer in our ecosystem has had huge evolutionary implications for intelligence, eco-dominance, and the like? It seems to me that winter/summer conditions are useful for these perposes..although the latitude may be enough...

[throttlelever]

Now it is a good time to aim all possible telescopes, including radio telescopes, to this planet. The ISS would be a great platform for carrying a VLA telescope. And a telescope in space would not suffer atmospheric noise.

[KyotoMelody]

Thank you, Steve. :) Thank you.

[wjfox2006]

Oh and I've subscribed by the way... great selection of videos you have there.

[wjfox2006]

If we want to view exo-planets "directly", and to actually see them, we need to build a whole network of telescopes in space. Individually these would be like Hubble, but they'd combine their magnifications to provide an ultra-powerful zoom. I really hope we do this eventually.

[AdmiralPeacock]

freaking sweet!
