CAROT exo 3B

The most massive and densest exoplanet upto date is a world known as COROT exo 3B. It is about the size of Jupiter and about 25 times that planets mass. This makes COROT exo 3B about twice as dense as lead. The degree of pressure put upon a human walking te surface of a such a planet would be unreal with a mass 25 times that of Jupiter, a human would weigh almost 50 times what they weigh on our planet earth. That amount of pressure would completely crush a human being skeletal system in an instant. It would literally be the equivalent of an elephant sitting in your chest.

CAROT 7B

• 

This volcanic inferno was the first rocky planet conforned to be orbiting another star outside of our solar system known as a super earth, it orbits a star 480 light years away and weighs about 5x the mass of the earth. It is 23x closer to its star than mercury is to our sun bringing its surface temperature up to a helish 4000 degrees Fahrenheit (2,200 degrees Celsius)

The same side is always facing the star and the other side is always in shadows, where temperature can drop to minus 350 f (minus 2'0 c). This rocky planet may be the left over core of a former gas giant whose atmosphere evaporated a long time ago. If so, it would be the first kind of this type of planet.  

Kepler 438b

470 light years away is a planet discovered but the Kepler space observatory known as "Kepler 438b". This planet is very strange not because it has any extreme features, but the opposite because it is, to date the most earth like planet we have ever found. The earth similarity indeed is a standard measure of how similar to earth another planet is with a score of being identical to earth in every way and 0 being nothing like earth. Kepler-438 boasts an impressive earth similarity index of 0.88 making  Kepler 438 super rare, and very special discovered in January 2015, this planet has all the right pre-requisite for alien life most importantly it is a rocky world, like earth and its proximity to its last star puts it in what scientists call the Goldilocks zone which is the holy grail of space exploration. The Goldilocks zone is when a planet is not too close to its parent star that it's too hot for life, yet not too far away that it's too cold water is essential to life, where there's water, there's probably life, but in order to have complex life there has to be a liquid water, which most of the time can only occur in the Goldilocks zone

Hd 188753AB first world with triple sunset

Triple sunset on hd188753ab

You may remember that Luke sky walker's home planet of tatooine in Star Wars had two stars but as if often the case, red life can be much more amazing than science fiction, 149 light years from Earth is a planet with not one bit two but three "stars" this three star planet which goes by its catalogue name of hd 188753ab, sits within the triple star system hd 188753ab. If you could live in this planet you would experience triple shadows, and constant eclipse as it's three parent stars cross each other's. Paths andof course you would see some of the strangest and most beautiful sunsets and sunrises in the universe.

J1407b

J1407b

J1407 b is located four hundred light years away from earth and those planatery rings that are 200 times bigger than the rings of Saturn scientist don't completely understand how this strange planet managed to acquire rings of such an enormous size the rings of j1407b are so so large that if saturns rings were as large they would dominate the earth's sky and appear much larger than a full moon. 

Gj1214b The water world

Nick named the water world a planet catalog as GJ 1214b identified as ocean that had absolutely no land, not unlike the water plant scene in the movie "interstellar" and anyone on the surface  of Gj1214b  would only see ocean in  all directions to global ocean on GJ1214b are also miles deep stretching all the way down into the planets core making Gj 1214b a unique water planet

Travelling to Gliese 581d

This is Gliese 581d it's a large rocky earth like planet the nearest known it just possible that this world or one like it could in the future become home to the human race a second century against the unforgiving blackness of space. Discovered in 2007 it seven times bigger tha earth It orbits a star smaller and redder than our own it lies just the right distance from its sun to allow water to exist on the surface but even if this is the perfect home away from home there is a fundamental problem we have to over come Gliese is a very very long way away more than 20 light years that's 120,000,000,000,000 miles to get some idea of this extraordinary distance then the challenge it presents I'm going to imagine that we could hitch a ride on the fastest man-made object in existence voyager 1 was launched in 1977 now over 30 years old it's Travelled more than 13,000,000 miles its mission so far has taken it to Jupiter and Saturn by using their gravity to boost the speed  little spacecraft has entered the record it might not look fast but voyager is racing through space at 11 miles a second on Earth 11 miles a second looks like 39,000 miles an hour at this speed we could circle the globe one an a half times in an hour so how long would it take a space shot travelling at voyager speed to get to the nearest earth like planet Gliese the answer reveals the true scale of the cosmos even travelling 11 miles a second the journey to Gliese would still take over 350 thousand years I think we have a chance to become a lasting part of the ever changing universe and discover what other wonders it might hold but to do this we have to developed a new technology on the enormous scale and that's going to take some serious engineering if we could build a machine capable of travelling to other solar systems we'd open up a fascinating possibility the survival of the human race billions of years present day engineers have begun thinking about the principles of building such a ship, it could use atomic energy or perhaps more exotic fuels such as antimatter supplying it with enormous amounts of power yet I think the main challenges won't be technical the first will be finincial the cost of constructing an interstellar spacecraft would be huge and for the society that made it there would be little payback they would never see It again 

So constructing this greater machine will either be the greatest act of generosity in history or it will have to be funded by the travelling themselves and that raises the the second problem even if it could travel the mind numbingly fast say a thousand times faster than voyager 11,000 miles a second, a journey to the nearest Star system will still take "seventy three" years
