Recently, scientists studied the skies, hoping to find signs of life on distant planets. They only found a few exoplanets that have traits that can sustain life so far, and one of them is K2-18b, which is 124 light-years away from Earth.

Exoplanets are planets that are not in our solar system. Scientists have been studying the skies for years and have been able to find only a few exoplanets that could have life on them.

Life, as we know it, requires several key ingredients: energy, carbon, liquid water, and a stable environment. These elements are essential for the formation and sustenance of living organisms.

Most exoplanets don’t have liquid water or oxygen. But scientists think K2-18b could support life because it has liquid water and oxygen and a few more of the essential things to support life. Scientists suggest that there are more exoplanets that are possible to have life.

Other exoplanets that can support life are: Proxima Centauri b, TRAPPIST-1e, and Kelper-186f. There are definitely More exoplanets that could sustain lifehave life in it, but scientists have to keep searching into he skies finding more and more life-sustaining exoplanets. Otherwise the exoplanets could not support life.

Part of the challenge when it comes to researching the existence of alien life is knowing where to look. Until relatively recently, the focus offor NASA’s search for life was Mars, but that began to change in 1992 with the discovery of the first planet orbiting another star outside of our solar system.

Although astronomers had suspected that there were other worlds around distant stars there had been no proof that they would sustain life until the future.
