The unmanned spacecraft named Voyager 2, which was launched into space in August 1977 as part of NASA's Voyager Project, came out of the Heliosphere (Solar System Sphere) after 41 (forty-one) years. With this phase, the Vayager 2 spacecraft became the second vehicle in human history to enter interstellar space, after Voyager 1. Thus, Voyager 2 entered the area where the Sun's magnetic field had little or no influence. This does not mean that it is completely outside the Circle of the Solar System. Voyager 2 is traveling through the outer layer of the Solar System and other interstellar space. Previously, it took NASA 1 (one) year to confirm that Voyager 1 was outside the Solar System. Both spacecraft had entered orbits of Jupiter, Saturn, Uranus and Neptune during their voyages.
The Invisible Side of the Sun Revived
Until now, none of the exploratory vehicles sent into space by many countries had the features to examine the Sun from every angle. For this reason, in our opinion, the north and south poles of the "giant star" are still a mystery for human beings in line with the current scientific and technological level. In order to understand this unknown, the European Space Agency (ESA) collected the data of all spacecraft sent for exploration purposes and obtained the estimated image of the Sun's north pole with a method; "collage study". Even if the result obtained by integrating the images obtained by the reconnaissance tools is not real, it gives some directly proportional information about the poles of the Sun. The polar information of the Sun, which remains hidden in this sense, has begun to be obtained thanks to the Solar Orbiter, which was put into practice in 2020. NASA/ESA joint study Ulysses observed the Sun from very different latitudes for an average of 20 (twenty) years. However, since these spacecraft did not have imaging technology, he could not send the images he obtained to Earth.
