2017-6-28: Solar Prominences ⬅︎
Anyone who observes the sun regularly through a solar telescope knows that the sun is very, very active, especially when it comes to solar prominences -- those bright, hot, gaseous, streams of plasma that extend thousands of miles from the surface of the sun. Prominences can appear one day and be gone the next.

We captured the image of the sun above using a special solar scope -- a telescope designed to safely view and image the sun and to reveal surface features better. How many solar prominences do you see? We count three -- a large one center-right, a smaller one below and a very faint one above. The large one is likely far larger than our Earth.

The plasma in a prominence is a hot gas consisting of electrically charged hydrogen and helium. It flows along invisible magnetic fields generated from deep within the sun's interior and then erupts above the surface forming long lines and even large loops. A typical prominence can be larger than the earth and the largest ones can extend half the diameter of the sun!

Remember to never look at the sun using a telescope unless the telescope, like the one we have, has a special solar filter to make viewing the sun safe.
