Not long ago we had no solid evidence of planets that existed outside our solar system. Known as an "extraterrestrial planet", speculations are still theoretical, until 1992 it was officially discovered an extrasolar planet. Later, a distant worldwith thousands of "fine looks" was discovered and mapped.

In the past decade alone, with the help of the Kepler space telescope (recently ending its mission), people have explored new planets at the multiplier level, in June. past, foreign planet 4,000 th has been confirmed.

This is a leap of astronomy as well as of human awareness, helping to mark the progress of people reaching far away in conquering their vision into the vast universe. To make it easier to visualize mass audiences, NASA created a video that ill‌ּustrated the positions of these planets in the night sky based on their detection speed. Let’s see how fast the detection speed is when the Kepler space telescope was launched in 2010.

Kepler has now closed its great mission and "left forever" last year, but its legacy has been received by other observatories such as Exoplanet Satellite Observatory (TESS) and continues to help find see more than 700 new planet candidates in the first year launched into space.

The statistical site of extrasolar planets has been discovered

Following it, the European planetary satellite observer (CHEOPS) will also be launched into space later this year and soon after NASA’s James Webb space telescope will fire in 2021. These two space telescopes may be able to do more than just observe exoplanets, which may help determine whether the outer surface of the solar system converges enough to be unique. life maintenance is similar on earth or not.
