Scientists discovered an alien exoplanet which is believed to be darker than coal.
There are over 800 billion planets in our galaxy. Imagine having a world full of people similar to us somewhere in the outer space. Over 100 billion galaxies have been discovered so far; there could be more.
We do not have sufficient resources to discover the space at the moment. However, nothing is impossible or unattainable when it comes to science. The experts are busy in creating an advanced telescope for the outer space. We’d be able to have an accurate number of galaxies in the forthcoming years.
The astronauts and scientists at NASA have discovered a unique class of planets that are as big as Jupiter. They are believed to be floating in the dark space, away from the light of a star. Exoplanets generally orbit a star that provides the light.
However, the ones NASA has spotted are in utter darkness. The scientists have now developed an interesting theory that there could be uncountable exoplanets in the Milky Way.
Here are eight fascinating facts about the exoplanets that are floating in our galaxy:
1) Certain planets are floating without a star in the space. Hence, it indicates that planets, in general, do not need a star to exist. There could be more planets of similar nature.
2) According to the experts, the newly discovered planets are located at an average approximate distance of 10,000 to 20,000 light-years from Earth.
3) NASA launched a spacecraft called Kepler in 2009 to look for any potentially habitable exoplanets. Kepler discovered planets that were in different sizes and had multiple types of orbits. Moreover, these newly discovered planets orbit stars that vary in size and temperature.
4) The Kepler spacecraft has unveiled a wide variety of planets. Besides gas monsters and terrestrial planets, it has helped identify a whole new class known as super-earths. It is believed that the super-earth planets are between the size of Earth and Neptune.
5) Scientists also discovered an alien-black exoplanet, which is believed to be darker than the coal. Only 1% of the sunlight hits it. The said planet is known as TrES-2b. It is currently the darkest known planet in our galaxy. However, multiple other worlds around other stars certainly await discovery.
6) According to Kelper’s discovery, around 1,200 worlds could turn up to be the dark planets.
7) As I have stated above, there could be uncountable exoplanets in our galaxy. Some of them could benefit the forthcoming generations as we have limited resources on planet earth. We’ll have to move out to save humans from being extinct.
8) According to the discovery made by NASA‘s TESS spacecraft, there are about 1,560 stars approximately 50 light-years away from Earth. They are most probably orbited by thousands of undiscovered planets. About a thousand of these exoplanets may be rocky; they may have a composition similar to planet earth. Certain may even harbour life. However, over 99% of these alien worlds remain undiscovered.
We are certain that things will change in the forthcoming years, and we will make discoveries. The Milky Way is massive, and there is still a lot to uncover.
