There are some things that are just not possible on our planet. It would certainly understandable that you would think that if it is impossible here on Earth, then it would be impossible anywhere else in the universe. But that's simply not the case. And the universe is for stranger than any of us can actually believe.


That's begin with the shadows. Your shadow on Earth is always alone and you are always used to seeing it this way as it follows during the day. You are also use to seeing everyone else with just one shadow, but this is not a universal thing that would be experienced elsewhere. You have won Shadow because our primary light source on Earth is our Sun. 

But what would happen if there were two Suns? 
A planet that orbits two star would look much like Tatooine two Stars wars, with two brilliant sun sets each days and two shadows instead of one for each person. Get used to only be science fiction on take the planet Kepler- 16b was discovered, which is a place that orbits two different stars. If you were suddenly teleported to the surface of of the planet, you would like die from the extreme temperature and lake of air to breathe. But assuming that you were teleported in a suit that could help you survive, then you would experience having two different shadows. A friend for your always lonely Shadow that you experience on earth. 


Our next extremely good place is planet that is likely completely covered in water. The ocean planet named GJ1214-b l. The planet is several times larger than the earth, which makes the Pacific Ocean on our planet seem like a puddle in comparison. Women do water covers over 70% of the Earth's surface, water only accounts for 0,0005% of the earth's total mass. On GJ1214-b however, water may account for up to 10% of the planets total mass. 

Which means that the entire planet would be covered in an ocean hundreds of kilometres deep. Our Pawan Ocean goes down only mere 11 kilometres and we already have terrifying the monster like this, and this, huge whales like this. So once imaginations can run absolutely wild with what fantastic all monster would exist in an Ocean that's over time than our own. 


We knows what could be lurking there if you crash land your ship on the surface. What is known is that at very bottom of the massive Ocean hundreds of kilometres beneath the surface, the pressure would be so intensive that the water at the bottom would be transferred into an exotic form of ice known as ice 7. This ice would not be like ice that you know on earth. If it will not be cold at all, but would remain in a solid form. This doesn't happen naturally on earth, but neither does our next example. Weather on Earth is often violent and unpredictable, but is extremely tame compared to other place in the universe. Take the planet COROT-7b for example, where instead of raining water if it rains down rocks. This is because half of the planet is scorching hot at 2600 c, while the other half is far cooler at 177c. 

The temperature on the hot side is enough to vaporize rock. And just like how water will evaporate and condense into clouds on earth, SO too will rocks condense into Rock clouds on this planet. This strange of cloud deal than rain liquid over magma back onto the surface. But since the atmosphere is cooler the father up goes and the temperature on the cool side is far lower, the magma rain will often harden into rocks before striking the ground. This planet seems like the closest place to help that a place in the university could get. But another planet has perhaps even more different weather.


Is planet known as HD 189773-b is located 63 light years away from us, is a little larger than Jupiter looks tiny planet in the universe. But that beauty is hinding terrifying secret. Its looks at this way because the planet's atmosphere is made up of silicate particles. Wind on the planet can scream at 5,400 mph, equal to 2 km/s 7 times the speed of sound.

 Temperature can reach up to 930 C. 5 most terrifying of all is that the planet rain glass sideways in its extremely violent 2 km per second winds. This is so fast and scary that if a storm like that happened to appear on earth, it would travel across the entire planet at the equator in just 5 hours and 35 minutes. But even this Storm pales in the comparison to the the mightiest wind sofa known is our entire universe. 
This is gas planet with the one side always facing it star, where temperature can reach 966 C. So, how does the dark side remains so hard still? The answer is extremely, wickedly fast wind, possible up to 22000 mph, equal to 10 kilometre per second for nearly 29 time speed of sound. 


But perhaps the most interesting place in somewhere that's much closer to home. Specifically, this place is called Titan, which is a moon of Saturn. It has such a thick atmosphere, that we did not even know what its surface looked like until 2005. It is a very different place, it has an atmosphere, river and lakes and it even rains like on earth. What the temperature is a bone shattering negative 179 c, which is so cold that water is as hard as rocks, and the chemical methane exist in a liquid state. The clouds, rivers and lakes on the Moon are made of methane, which is primary component of natural gas. Only 20% surface of the Titan has been mapped, but it is estimated that in that region alone, where is hundreds of times or natural gas and oil is located on all of Earth. There is so much gas on Titan, that is literally range it. 

The atmosphere is thick enough and gravity is weak enough that is attached a pair of running jump, then you could actually flap around the moon like a Bird, taking in all the alien sites of river and lakes. Of course you you would need a suit to protect yourself, but still, you would like just like in your dreams and achieve something that's impossible here on earth.
