NASA has recently discovered 17 new exoplanets where water is expected to be found. Based on new research, NASA has said that 17 exoplanets have been discovered in a recent study to search for life outside our solar system. In which it is expected that there will be an ocean of liquid water beneath the icy shell. Let us tell you that by doing this research for the first time, NASA has estimated that there may be water in the world outside our solar system also.
Apart from all this, now you must be wondering what are these exoplanets, so let us know today.
What are exoplanets?
Exoplanets are planets that orbit other stars and are located away from our solar system. The first confirmation of the detection of an exoplanet was made in the year 1992. According to NASA, more than 5 thousand exoplanets have been discovered so far. Recently, 17 of these exoplanets have been suggested to have water. That means there is a possibility of life on these also.
What are exoplanets like?
Let us tell you that exoplanets are of different sizes. They can be large and gaseous like Jupiter or small and rocky like Earth. There is also variation in their temperatures which can range from extremely hot to extremely cold. It is difficult to see them through binoculars. In fact, they are hidden in the brightness of the stars around which they revolve.
Therefore, astronomers use other methods to detect and study them. Like seeing the effects of these planets on the stars around which they revolve. Also, scientists rely mostly on indirect methods, such as the transit method, which measures the dimming of a star as a planet passes in front of it.
