During the mission, SOHO discovered a very rare periodic comet. They have already unveiled over 1,350 comets during the mission, but what they found was considered officially periodic. Many comets that SOHO has discovered have been identified as periodic, meaning that they follow their orbits around the sun more than twice and also have orbital periods that consists of less than 200 years. Astronomers have seen thousands of comets but have around 190 of them that fall under being periodic. The purpose of the SOHO mission was keep track of the sun and its orbit. So in essence, we were basically spying on the sun and its daily orbit routine.
The SOHO mission gave us an understanding as to why the solar corona exist and how it is heated to such an extremely highly temperature. The solar corona is the region around the sun that extends more than a million kilometers from its surface. This region can reach two million degrees, which is where all the heat is derived from (along with solar wind).The corona can only be seen during solar eclipses. The only problem is that scientists can’t really explain how the corona exists.
The SOHO mission also helped us understand where the solar wind is produced and how it’s accelerated. Solar wind is nothing but a hot and fast discharge of magnetized gas that streams away from the suns upper atmosphere. In the magnetized gas there are hydrogen and helium ions with a dash of heavier elements. Researchers like to compare it to a streaming pot of water boiling on a stove, it’s as the sun is
