New Planet found outside of our Solar System? How could it be possible?

Question

How could the Europeans know about something 170 trillion light years away???

Answer 1

Well, it's not 170 trillion light years away - it's only 20 light years.

Answer 2

You seriously need to take a class.

Answer 3

Becuase the flying spagetti monster told them about it.

   rAmen

Answer 4

With advance technology that every nation is using to try and look for these things. You should read the articles before you ask such a ignorant question

Answer 5

they are lying communist is what they are, They will do anything to destory american including making up planets to make us look bad. DON'T TRUST THEM DAMNIIIIIIIIT.

Answer 6

i think all the star are planet or some one explain.

Answer 7

Man, Pluto's going to be pissed.

Answer 8

It is simple, they use a chromatography technique to see the stars and observed any glimpse of a planet orbiting it, which result in a small decrease or increase in the sun overall radiation emission... As for the distance of the observation, we don't really need it to see it, but just use special calculation to infer the presence of another body. They are other detection techiques used to know if the planet is solid or a gas one, and others to know the atmosphere composition of the planet (like using radio telescopes)... Anyways, this is science...

Answer 9

I believe it was 170 trillion miles away, not 170 trillion light years away. It's a big difference in the number because it's something like 2.4 billion miles per light year. Still a long way away, but there are telescopes powerful enough to detect things at that distance.

Answer 10

It's only 20.5 light-years away. They use HARPS (High Accuracy Radial Velocity for Planetary Searcher), perhaps the most precise spectrograph in the world.

Answer 11

We actually put it there in the first place. It's all part of a global conspiracy, and YOU'RE the ONLY person who's not in on it.

Ever seen the Truman Show? You're the equivalent of Truman. Look for the cameras, you might just find one.

Answer 12

no its not, Filipinos did.

Answer 13

They don't.  It is all an insidious plot to fool you.  But stay vigilant, young Padawan.  Don't let them push any of their evil scientific beliefs on you!  Teach your children the wonders of alchemy and spiritism instead.

Answer 14

I did not read the article, but in school we larned how scientists do this. If you read the article it may have contained the answer.

Answer 15

they have satellites

Answer 16

in case you haven't noticed , any thing you can imagine is possible. all you have to do is believe and act as if it already exists. so get busy!

Answer 17

don't know but it is pretty d**n cool. I can't wait to see what they find out. They really think it could sustain life, so far.

Answer 18

Modern science are capable of producing high-teched telescopes,,and it is possible and it is true that there are millions of planets in space,,we just belong in one galaxy and we are just a small part of it,,basically there are still lots of undiscovered planets in our galaxy alone,,millions,,or even billions,,so come to think of it,,there are billions of galaxies in the whole outer space,,and if there are billions of planets in our galaxy alone''milky way'' how many more planets can there be in the whole outer space? shocking isnt it?

Answer 19

ok first of all it is not a trillion light years away..it is mearly 20.5 light years away. So if we could travel the speed of light, it would take us a little over 20 years to get there. They say that it may be inhabitable. It has a red dwarf star as it's source of light. Smaller than our sun but 10 times bigger than our moon. Half the side of this planet is of darkness and the other half is lit all the time. The red dwarf star gives off a dimmer light and a red glow. You ask how can they do this, well technology is amazing, is it not?

Answer 20

...The same way American, Chinese, Japanese, and other international people would know. And maybe they looked, too. That would do it, don't you think? Light is a wonderful thing. Oh and it isn't 170 trillion lightyears away. If it were, nobody would see it since according to the big bang theory the universe has not existed for that long and the light would not reach us for another 169.85 trillion years or so.

So it was in millions then. If you truly don't know how people find things in space, then you need to figure out a thing or two about astronomy. We are not in the stone age.

Sorry for my cynical attitude here, but that was a truly ridiculous question.

Answer 21

By focusing their large telescopes on distant stars they can tell if there are objects regularly orbiting them.

Answer 22

The find was pos­si­ble thanks to an in­stru­ment known as a spec­tro­graph on the Eu­ro­pe­an South­ern Ob­serv­a­to­ry’s 3.6-meter tel­e­scope at La Silla, Chil­e. The in­s­tru­ment, called the High Ac­cu­ra­cy Ra­di­al Ve­loc­i­ty for Plan­e­tary Search­er, is touted as one of the most suc­cess­ful tools for de­tecting exo­pla­n­ets to date.

Answer 23

chuck norris told them

Answer 24

because, just like us, they are constantly coming up with more powerful ways to see everything in space, and they made it to mars (i think, don't quote) and a really powerful telescope saw it. The discovery was also done (i think, don't quote) by the Americans as well.

Answer 25

very powerful telescopes maybe.

Answer 26

Telescopes. They're generally used for seeing distant objects. The European Space Agency has quite a few of 'em.

Answer 27

Very large telescopes and mathmatics.  Who knows?  The universe is expanding and we are yet discovering new things about it every day.  I wonder what new things will be discovered 100 years from now?

Answer 28

the planet's mass causes a measurable "wobble" (perturbation of orbit?") in the star that can be detected if you have the right expensive equipment on a satellite and a computer to crunch data.  i think.

Answer 29

They looked.  They calculated, they looked again, they calculated some more.  It's only 20 light years away, that is in our backyard.  It is only the 230th extra-solar planet to have been detected  in the past dozen years or so. The difference is that this one appears to be rocky and about 5 times the weight of Earth.  All the others have been gas giants.  One famous astronomer (Patrick Moore) interviewed on radio the other day said that it was inevitable and more will almost certainly be found.   What happens when we detect music coming from such a planet by radio?  Hmmmm?  Does the US Baptist Church collapse or does it make up another set of lies?
