The very dark color of the moon can be used to calibrate X-ray imagers to properly record the ‘zero signal’ state, while the eclipse will block out the disk of the sun letting the light from the mysterious inner corona within 100 km of the solar photosphere shine into various experiments for detailed study.
This page introduces you to some of the unique observations – Why is it that the corona shines with such a unique color and texture?
The year was 2001 – the first of the new millennium. It was also the year astronomers reached a historic milestone: they had catalogued more planets orbiting distant stars than the eight we knew about in our own solar system!.
There are many features of the sun that will likely be seen during the total solar eclipse including the spectacular corona, helmet streamers, the thin red ring of the chromosphere, and perhaps a few prominences.
One of the most beautiful things about viewing the solar corona during a total solar eclipse is the light from the corona itself.

Science for a healthy planet and safer world – Why is it that the corona shines with such a unique color and texture?
It took more than 20 years to broadly accept that mankind is causing global warming with the emission of greenhouse gases. Why have warnings about climate change been ignored ?
Warming of the climate system is unequivocal, and scientists are more than 95% certain that it is primarily caused by increasing concentrations of greenhouse gases produced by human activities.
How does the solar eclipse affect the atmosphere on Earth? Participate in a nation-wide science experiment by collecting cloud and temperature data.
The Science: Mechanics of Solar Eclipses
- A total solar eclipse is when the Sun is completely covered by the Moon. This diagram illustrates in more detail what happens during a total eclipse:
- A partial solar eclipse is when the Moon covers only part of the Sun, taking a « bite » out of it.
- An annular eclipse occurs when the Moon covers the centre of the Sun, but not its edges, leaving a ring (or annulus) of the Sun visible around its edges.
