Alfvén 4 found that the supposed coronium is actually highly ionized iron gas at temperatures of about a million kelvin. The discovery of emission lines in the spectrum observed during the eclipse of 1868, attributed to helium 2, and during the eclipse of 1869 (attributed to a new element called coronium) 3 led to the discovery of the high temperature of the corona. The solar corona, normally too faint to be seen with the naked eye but revealed during total solar eclipses, has been known since at least its description by Kepler in 1605 1, though he thought it could be a lunar atmosphere.

We also discuss some additional bonus effects of eclipse observations, such as recreating the original verification of the general theory of relativity. This review explores the past decade of solar eclipse studies, including advances in our understanding of the corona and its coronal mass ejections as well as terrestrial effects. This set of eclipse observations will again complement space observations, this time near the minimum of the solar activity cycle. This event, which will cross coast-to-coast for the first time in 99 years, will provide an opportunity not only for massive expeditions with state-of-the-art ground-based equipment, but also for observations from aloft in aeroplanes and balloons. On 21 August 2017, the first total solar eclipse visible solely from what is now United States territory since long before George Washington's presidency will occur.

In addition, eclipse views boast of much higher quality than those obtained with ground-based coronagraphs. In fact, the region of the corona best observed from the ground at total solar eclipses is not available for view from any space coronagraphs. Today's heliophysicists benefit from continued instrumental and theoretical advances, but a solar eclipse still provides a unique occasion to study coronal science. Observations during total solar eclipses have revealed many secrets about the solar corona, from its discovery in the 17th century to the measurement of its million-kelvin temperature in the 19th and 20th centuries, to details about its dynamics and its role in the solar-activity cycle in the 21st century.
