For centuries, scientists have been searching for answers to some questions. Yet they could not even go a single point in solving those questions. Such a question, is the earth the only source of life?

However, scientists from the US Space Research Agency (NASA) have now discovered three planets that can help solve those questions. The three planets can shed light on the mystery of life on this planet other than the earth.

NASA found that these three new planets have a new world system that we have never seen in our solar system.
Researchers say that these mysterious planets may be the 'lost source' that can be a great gift for scientists to find 'aliens'.

These three new planets are orbiting a star. The star is only 3 light years away from our sun. They are the nearest and smallest of such planets ever found.

Researchers discovered these planets through the NASA Exoplanet Survey Satellite (TESS) project. The project was sent to space in the 21st. Its purpose is to find all the stars and planets in which life has evolved.

The new three planets have a rocky planet, which is somewhat larger than our Earth. The remaining two planets are made of gas, which is a bit bigger. And these features make the planet a 'lost source'. Because the rocky planet looks a lot like Earth or Mars. The gaseous planets look like Jupiter or Saturn.

Maximilian Gunther, head of the planetary exploration team, said the new planets could help understand how gas and rocky planets were created in this space.

Scientists think that the planet may have temperatures that look like the earth, which can help the life of the organism. However, its atmosphere is thought to be very light, while its surface temperature is quite warm.
