The American Space Agency (Nasa) released data from unpublished observations of atoms surrounding the Solar System. Using the Ibex spacecraft, astronomers were able to capture the chemical elements from neighbouring regions and measuring the volume of these materials inside and outside the heliosphere, the "bubble" around the Sun that protects the Earth and other planets of cosmic rays.

The data were announced at a press conference held on the afternoon of Tuesday in Nasa's dependencies. Six studies on the results collected by the Ibex mission will be disclosed in the February issue of the magazine "the Astrophysical Journal", one of the main scientific publications on astronomy in the world.

The study showed the difference in rates of hydrogen, oxygen and neon gas within the zone of influence of the Sun and clouds of cosmic dust that surrounds the Solar System. A decade ago, another Nasa mission called Ulysses had already detected the atoms of Helium coming from outside the solar bubble.
