NASA discovered more than 100 planets outside the Solar System

On July 18, an international team of scientists announced that 104 more planets outside the Solar System have been discovered, of which four planets may have Earth-like surfaces.

The outer planets were discovered thanks to the powerful support of the Kepler space-based telescope of the US Aerospace Agency (NASA) as well as the Earth-based telescopes including four in Mauna. Kea, Hawaii.

Astronomer Evan Sinukoff from the University of Hawaii said the diversity of newly discovered planets is amazing.

According to him, many planets about twice the size of the Earth, rotate very close to the star, the planets have temperatures of more than 1,000 degrees Celsius.

There are two planets that can have the same temperature as Earth, although their rotation is smaller.

In this newly discovered planetary series, 21 planets in the region can survive life, far enough away from the host so that water can exist in liquid form and develop life.

Among these, there are 4 planets made of rock, 20-50% larger than Earth, flying close together at the same star system 400 light years from Earth.

Because the star planet's temperature is lower than that of the Sun, scientists believe that two planets may have temperatures similar to those of Earth, although their rotation is smaller.

The Kepler telescope is still constantly observing 150,000 stars that can have planets flying around. With a value of up to $ 600 million and launched in space in March 2009, Kepler is the first telescope designed by NASA to search for planets of the size or structure of the Earth outside the Solar System. By measuring the brightness changes of a host star when a planet passes by.

During the mission, Kepler has discovered 2,326 exoplanets so far. By observing these extrasolar planets, NASA scientists hope to gather more important information for research and search for extraterrestrial life.

Until now, the scientific community has discovered a total of nearly 5,000 planets, with 3,200 of these confirmed.
