Helium gas detected around Earth's solar system for first time

Helium has been detected for the very first time as a constituent of the atmosphere of an alien planet. This massive discovery hints that it is viable to study the atmosphere of various exoplanets in the universe without launching a space telescope, as per the researchers.

This new method will aid in probing the upper reaches of an exoplanet, which have high-energy content, according to Jessica Spake, the lead author of the research.

Researchers have to wait for this comet-like world to move in between the Earth and the exoplanet’s closest start so as to study a faraway planet’s atmosphere.

As the planet will block a portion of the light coming out from the star, so this process will be a complicated one with only few instances of success.

WASP-107B changed all of that. It is at a distance of 200 light years.
