![]() They've observed the jets before, but there were unfortunately too few observations to get conclusive evidence. One proof could be plasma jets, which scientists expect to be produced by the reconnection process. "We need to find proofs that (magnetic reconnection) is really the story" says Gurman. There are four outer layers of the Sun, and the Corona is the outermost one. However, the corona can be viewed during a total solar eclipse. That makes it difficult to see without using special instruments. The corona is usually hidden by the bright light of the Suns surface. The outer layers are the Corona, the Transition Region, the Chromosphere, and the Photosphere, while the inner layers are the Core, the Radiative Zone, and the Convection Zone. The Short Answer: The Sun’s corona is the outermost part of the Sun’s atmosphere. As a direct consequence of this theory, the heating process should occur much closer to the surface of the Sun than previously thought, but no one really knows how close. The layers of the Sun are divided into two larger groups, the outer and the inner layers. Experts do not even agree on the approximate length of time these patches remain active. ![]() No one has directly observed any magnetic field reconnection. It's a faily inefficient source of energy, but the sheer number of these small magnetic patches on the surface of the Sun makes the process a viable solution to the 50 year old problem of what heats the solar corona.Īll is not quite clear yet. They will then reinforce what they have learned through five reading comprehension questions. Because the laws of electromagnetism prohibit the intersection of two magnetic field lines, every time magnetic field lines come close to crossing they are "rearranged," and this magnetic reconnection continuously heats the solar corona. 5th Grade Earth & Space Science Worksheet The Sun: A Diagram Get to know Earths star with with this diagram and vocabulary worksheet Children will learn important solar terminology and trivia as they review a diagram of the Sun. ![]() Now most scientists believe that the heating of the corona is linked to the interaction of the magnetic field lines radiating out of the small patches mentioned above. But there was a problem with that theory: those giant loops disappeared during solar minima, while the corona does not. They thought the heat energy was coming from the active regions, where the spectacular giant loops are seen in Ultra-Violet and X-rays. During this period of darkness, one can witness the solar corona, which is usually too dim to. According to Joseph Gurman, an astrophysicist at the Laboratory for Astronomy and Solar Physics at the Goddard Space Flight Center, people already suspected that magnetic fields were playing an active role in the Solar Corona problem. image depicting moon passing between the earth and the sun. ![]()
