The latest discovery by scientists reveals interesting news for astronomy. The presence of water in two planets 218 light-years away from Earth. They believed that only rocks and metals could be found in both, but no. The information was obtained by data from the Hubble telescope and the telescope sptizer. Kepler-138 c and Kepler-138 d, because they have water in their composition and a larger size, are now even more Earth-like.

Scientists Discover Water On Two Exoplanets Called 'Super Earths'
A team of researchers published an article in the journal Nature Astronomy, in which they report having discovered water on two exoplanets with similar characteristics. those from Earth: Kepler-138 c and Kepler-138, both located at a distance of 218 light-years, in the constellation Lyra, where they orbit the red dwarf star Kepler-138.
Researchers also found water
The main similarity between the planets and the Earth can be seen in their composition, which was believed to be just rocks and metals. In addition to its size, of course, which is slightly larger than Earth's. But does not stop there! The similarities are even greater, according to the scientist's discovery. Much of the planet's volume is filled with water, a fundamental element for life, especially human life.
Scientists reached this conclusion through data obtained by the Hubble and Spitzer telescopes, which showed detailed images that even indicated the presence of water.
Björn Benneke, a scientist at the University of Montreal, spoke a little about the discovery: “We previously thought that these planets that were a little bigger than Earth were big balls of rock and metal, like bigger versions of Earth and that's why they were called Super Earths. The scientist adds: "However, we have now shown that these two planets are quite different in nature: a large fraction of their total volume is composed entirely of water."
The group pointed out that the water on exoplanets may not be concentrated in oceans, as we see on Earth.
