A presentation of the cooperative ESA/NASA mission to send a spacecraft out of the elliptic plane and over an unexplored pole of the Sun. No spacecraft has ever ventured so far from the elliptical plane. To do so requires Ulysses to travel first to Jupiter, using the gravitational pull of the giant planet to propel itself towards the southern solar pole.
A shadow eclipses the face of a star. Darkness falls where once there was light leaving only the faint trace of the solar corona.
Deep inside the straís core gravitationnal pressures raise the temperatures so highj that ions of hydrogen are fused together to formions of Helium, releasing vast amounts of energy.
This enregy forms a heliosphere, a zone of solar influence in which the solar wind and its magnetic field dominate interstellar space.
How far this starís heliosphere actually extends is not known. Perhaps 7500 million kilometers; maybe up to 15,000 millions kilometers.
The star shakes and vibrates as it furiously resists the forces of its own gravitational mass. It has engaged in this titanic struggle since it was first formed more than 4,5 billion years ago.
Eventually, it will lose ballooning outwards to become a Red Giant and consuming all before it.
One day it will shrink again ending its days as a tiny, burnt out, stellar remnant, known as a White Dwarf.
This is no ordinary star, this is
