The Hunt For A Second Earth

by Moin Uddin Ahmed Tipu

NASA’s Kepler telescope was launched to find other planets just like earth– and now, scientists think they may have found not just one, but three! Trace shows us where they are in the solar system and why the discovery is so important.

“10 Remarkable Exoplanets”

“From a planetary perspective, there’s no place like home — as far as we know, at least.”

“Exoplanet Kepler 22-b offers best hope yet for a new Earth”

“Nasa discovers planet that is about 2.4 times the size of our own and lies in the ‘Goldilocks zone’ of its solar system.”

“Five Potential Habitable Exoplanets Now”

“New data suggests the confirmation of the exoplanet Gliese 581g and the best candidate so far of a potential habitable exoplanet.”

“Are we not the only Earth out there?”

“If another Earth exists in the universe, wouldn’t it need to look like, well, Earth?”

um well your last one is not a very good idea Gliese 581d the side pointing to the red dwarf can heat up two 500 degrees Celsius and the other side pointing away from the sun can reach -420 Fahrenheit the only habitable part is a small strip in between the right and left side which may inhabit life but try to fit half the earth's population in-between a planet

Well… if radio waves we're sending get there maybe they will lend us a Light speed space ship, and bring us too their planet…. as slaves!!!!
Good luck future grand children!

4.5 x earth!?!?! You would break your legs just walking haja

well i mean, the 3 sun planet seems pree cool but that gravity would just wreck our bodies.

I would laugh if humanity was at an end on Earth here due to a World War 3 or something and we sent people there as a last resort just to have the planets be destroyed by the time they get there.

I wouldn't mind waiting twenty year to go to another planet if we could got to the speed of light

If the exoplanets are much bigger than Earth wouldn't their be a problem with gravity?

As my teacher says humans came from seed or aliens brought us in here.

They better hurry up and build hyperdrives and spaceships already I don't want to die 10 years before that happens

joao roberto September 16, 2016 - 6:59 AM

how humans would adapt to such strong gravity?

Mitka September 18, 2016 - 4:04 AM

bullshit we haven't returned to the moon stop misguiding people

We did a project on this exact topic in my ELAR class in 6th grade, We had to research a planet that is similar to earth and could be habitable. The reason for this project was because we were reading the book 'a wrinkle in time'.

Does anyone hear how he says that a planet is not to far to burn up and to close to be covered in ice

Hoshii Melon January 14, 2017 - 11:14 AM

we all are going to die on this blue marble, so just accept it

Zachary Chandra March 4, 2017 - 9:31 AM

Number 1 is Kepler 438 b.

Why don't they put rats or something that breath our oxygen to see if it's a breathable planet

Violeta Escarlata April 3, 2017 - 7:41 PM

First! We need to check if someone lives there, and see if we are welcome to visit them.

Viktor Nguyen October 4, 2017 - 5:36 AM

anyone playing space engine are gonna try searching these planets? xD

Ahmed Adan October 16, 2017 - 9:29 AM

yes

Nutty Salt June 20, 2018 - 1:51 PM

I prefer Kepler 186f
