Planet Earth is rumored to have a 'twin'. About 160 Earth-like rocky planets were discovered by scientists. They identified the planets from a total of about 4,500 exoplanets discovered.

But to find out the condition of the planets, the United States Aviation and Space Agency (NASA) was asked to build a new, more sophisticated telescope. It is recommended by Caltech Astrophysicist Fiona Harrison's committee.


"The most amazing scientific opportunity ahead of us in the coming decades is the possibility that we could find life on other planets orbiting stars in galaxy environments," Harrison said.


They recommend NASA build a more advanced telescope than the Hubble Space Telescope and be equipped with infrared, optical, and ultraviolet sensors. The new telescope will cost about $11 billion and be launched in the early 2040s.


The National Academy of Science, Engineering and Medicine advises government agencies, such as NASA and the National Science Foundation, what research goals astronomers should prioritize in the coming decade every 10 years.


In the latest report, the advisers highlight three key research priorities: to better understand the nature of black holes and neutron stars, and how galaxies form and evolve.


In addition, the research was conducted to identify Earth-like planets, which are predicted to be habitable, as well as see biochemical signs of life in other planetary systems.


"With telescopes like that, we're going to see different little dots," Bruce Macintosh, an astrophysicist at Stanford and a committee member, told The Atlantic.


According to him, by analyzing the light reflected from the exoplanet, scientists can find out the chemical composition of its atmosphere.


Atmospheric evidence of oxygen, methane, and water could hint at the existence of life on the planet, although astronomers need to rule out other explanations for other chemical signatures, such as volcanic activity.
