The extrasolar planet has a common element in the universe

The galaxy still possesses secrets that many scientists seek to discover and no doubt, as science advances, we realize the wonders that exist in the universe. On this occasion, scientists from the Department of Physics and Astronomy of the University of Exeter in the United Kingdom carried out an exhaustive investigation in which they determined that there is a giant gaseous extrasolar planet called WASP-107b that possesses Helium.

In addition to hydrogen, helium is one of the most common elements in the universe, but the reason why scientists are surprised is because none of the other 3,500 extrasolar planets in the galaxy possess Helium. The fact that on that planet if there is such an element makes the news surprising and historic, because it creates a positive line to look for more exoplanets in the universe and observe their evolution.


The extra-solar planet isn’t as dense, so it doesn’t retain its atmosphere.
In order to determine the presence of Helium on the extrasolar planet, a study had to be carried out in the planet’s atmosphere, this was done by observing the planet’s translation in front of its stars, in this way, the amount of light absorbed was calculated according to the external zones of its atmosphere. The ultraviolet spectra of satellites in space are the ones that calculate the density of light, but as they do not have enough technology to measure it at 100%, they only achieve it with the nearest planets.

Because of this, they used the Hubble telescope with infrared spectrum and determined that the wavelength of helium in the WASP-107b is 10,833 Ångström. However, the exoplanet is not very dense and cannot retain its atmosphere, so its ultraviolet radiation causes its gases to heat up and expel the atmosphere as if it were wind.
