The world of science is full of mysteries and the astronomers explore these mysteries daily. In the most recent update, astronomers recently carried out one of the most detailed radio searches ever on exoplanet K2-18b,

When astronomers observe distant exoplanets, they sometimes encounter a frustrating result: instead of revealing the chemical fingerprints of an atmosphere, the data appear almost completely flat. Those flat spectra can make it difficult to determine whether clouds or haze are obscuring the atmosphere being observed.

When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of biology because they are often produced by living microbes. However, scientists can be misled because certain geological processes can produce chemical signatures identical to those of living organisms.

Alas, it’s not a study-abroad course – yet – but exoplanets may provide insight into how life formed on Earth.

Scientists have been working on a plan for nearly a century to use the Sun as a telescope to capture high-resolution images of alien worlds, which could reveal rivers, continents, and even city lights.
