It all began in 1994 when Dr. Alexander Wolszczan observed unusual variations in the signal of a pulsar (known as Beta Pictoris) and discovered the first planet outside the solar system. Since then, more than 1888 more exoplanets have been detected and have thus laid the way to study and explore about the heavenly bodies beyond our solar system. Thanks to this, the Big Bang Theory too has revealed a lot of information about the history of the universe.
Here we have surprising information about the mysterious planets in the universe known so far. Have a look!
Gliese 581C is forced to face one way as it orbits its red, small star. This way, one part of it is always facing the dwarf star, thus burning on one side and frozen on the other. Though it is believed to be the best candidate for human expansion.
The first rocky planet discovered in orbit of another star, CoRoT-7b, has the temperature of 4000 degrees Fahrenheit on one face while the dark side reaches temperatures as frigid as 350F, resulting in rock rain.
How, you ask? Well, because this huge, rocky planet is made mostly of carbon that turned into diamond and graphite. According to Forbes magazine, only 0.182% of 55 Cancri e would be enough for mining to pay back the total debt of all the governments in the world, close to $50 trillion USD.
Planet Methuselah is nearly triple the age of Earth and was likely formed only one billion years after the big bang.
The gas giant which is half the size of Jupiter weighs roughly the same as a ball of cork!
Approximately 300 light years from the Earth, this pretty planet is at a distance 20 times greater than the space between the Sun and Neptune (about 60,000,000,000 miles) from its closest star, thus making it the loneliest planet yet discovered.
It is the darkest planet in the known universe. TrES-2b is a planet that absorbs a huge intensity of light but reflects less than 1 percent of the light that strikes the planet. As a result, it is darker than coal.
Located 400 light years from Earth, J1407 b flaunts it planetary links like a queen. If Saturn had a ring system of similar size, it would be all over the Earth's sky and appear much larger than the full moon.
The extremely high temperature (about 1,832 degrees Fahrenheit) and pressure exerted on this gas planet results in a significant evaporation of various atmospheric gases. During the research, gases hydrogen, oxygen and carbon were detected rushing away from the planet, leading to an entire new species of planet classification, referred to as Chthonian.
It orbits pretty close to its stars when compared to Earth, only 4.3 million miles. The ice on the planet is held together by immense gravitational forces, thus making it an ice-tin.
