ESOcast 96: Ultracool Dwarf and the Seven Planets

Astronomers have found a system of seven Earth-sized planets just 40 light-years away. Using ground and space telescopes, including ESO’s Very Large Telescope, the planets were all detected as they passed in front of their parent star, the ultracool dwarf star known as TRAPPIST-1.
Three of the planets lie in the habitable zone and could harbour oceans of water on their surfaces, increasing the possibility that the star system could play host to life. This system has both the largest number of Earth-sized planets yet found and the largest number of worlds that could support liquid water on their surfaces. This ESOcasts describes the findings and shows a little of what they might mean.
The artist’s impressions in this video are based on the known physical parameters for the planets and stars seen, and uses a vast database of objects in the Universe.

[@ketfoen]

this very very exciting. I never expected such a remarkable discovery in my lifetime. This truly is the golden age of astronomy!

[@oldtoby4062]

This makes me so happy, I can hardly explain why

[@ThePoetinres]

Name those planets after 7 dwarves!

Very nice narration! Discoveries like this always leave me in a positive, excited mood~

[@tasneembel8613]

That's fantastic!!the world is nearing the most cutting-edge revolutions of all.

[@Alienasa1]

Awesome! Also nice to see you guys are working with SpaceEngine!

[@untouchable360x]

If we conquer and colonize them, we will be "Lord of the 7 planets and protector of the universe"

[@criticalpoint7672]

40 light years away ? It would take us with our current technology about 20 million years to reach there.

[@TheParagonmen]

with current technology will take us just minute or less... 3D technology ))))

[@luckyluke7355]

Critical Point exactly with 40000 Miles per Hour about: 2 Million years

[@Jansen33]

Too bad red dwarfs are far more erratic than main sequence stars. These exoplanets better have kickass magnetospheres. Just saying, brotato chips.

[@jesusvieira7180]

This is so amazing!!!

[@Alex-wg1mb]

Where is the reference to the Space Engine planetarium?! I think it's unfair to hide such gorgeous project.

[@ecuaplanes5441]

I'm so happy with this :D

[@carlotroger5653]

Très intéressant.

[@NinhGhoster]

Vietnamese subtitle was done. Please update it! Thanks!

[@jdamacenofrance]

Just 40? 4 years and no we will hardly see it, imagining 40!

[@mariadaluzmoutinho5701]

É uma grande descoberta!! Só sendo possível estudar de longe ...Estes planetas te alguma lua?? O conhecimento é o nosso destino!!

[@adamreilly4108]

What will NASA even do if we discover that these planets do indeed harbour life? Will we try to contact them in some way? What are NASA's plans?

[@demo2382]

Well I think these planets are a lot younger than earth. If there was life, they may be in the early stages so I dont know if contacting them will pan out. Though it wouldnt hurt to try. But I'm sure NASA's plan are to do what they can only do at this time..... and that's just keep studying them. There are plenty of organizations out there already looking into deep space travel.

[@billytherebel5122]

We can travel there with the new discovery of the way to travel faster than light

[@nangephriam1211]

If only infinity stones are real and can easily find I would visit all these planets in a moment.

[@godfree2canada]

it's a trap!

[@TheParagonmen]

yes sir!

[@ohsoyoureawrestlernow9756]

Planet bieber!

[@adalbertotay3767]

Adalberto

[@marcelineingot9359]

Hahaha, wake me up when we get there...Not!

[@oalithgow]

tbt ESO

[@TheParagonmen]

everything born on this planet stay forever on this planet....easy right!

[@66oyoyo]

Ned Ned until the asteroid comes, yes

[@marvpgee8332]

its right. cuz noone can leave the earth. thats why nasa is faking space. these TWATS

[@pakdungplung8723]

ye can find the most of this system in pleiades constellation , there are a bunch of this sort of system which has planets could support life as if the earth. abundant of its collected there . made my name tag to it...caused they are abundant. ye better look down first before parking up there...

[@DarkFenix139]

And not a single reference to "Space Engine". Unscrupulous..

[@mitkomitaka7735]

??????????????2

[@cosmicsurfer5911]

They are getting better at the CGI theories, still lies though.

[@nicholascurry7014]

Cosmic Surfer dude they have to use CGI to show us the video it's not like they have video of this they know what they look like based on the data they are getting from the planet

[@IDyn4m1CI]

That looks like SpaceEngine, so yeah it looks pretty realistic

[@cosmicsurfer5911]

Planets do not hand out data to nassholes. There is no way to even understand what a planet is, ever seen a planet with your own eyes. I will tell you what their data is based on, disinformation to the masses.

[@cosmicsurfer5911]

Something that looks realistic is not necessarily realistic though.

[@IDyn4m1CI]

Cosmic Surfer Cool man, but unless you have any proof or evidence that they're spreading disinformation all the bullshit you just said is completely irrelevant.

[@mametfelixlaudat1365]

We already lost count of the number of earth like planets. Soon people will lose interest,unless a means of efficient and fast transport to these worlds be found.Then what is this insistence on earth size planets ?Why not accept any size offered there , may be the bigger the better?and what if humans poison out their earths atmosphere before being able to escape there ?shouldnt they look into preserving their own planet first, and change their genetic structure to withstand the cosmic journey,as a prerequisite to colonies these worlds?
