Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

The edge of the Sun is shown sporting a large gaseous prominence that looks like a science-fiction alien. Please see the explanation for more detailed information.

Monster Solar Prominence

Explanation: The monsters that live on the Sun are not like us. They are larger than the Earth and made of gas hotter than in any teapot . They have no eyes, but at times, many tentacles . They float . Usually, they slowly change shape and just fade back onto the Sun over about a month. Sometimes, though, they suddenly explode and unleash energetic particles into the Solar System that can attack the Earth. Pictured is a huge solar prominence imaged almost two weeks ago in the light of hydrogen . Captured by a small telescope in Gilbert , Arizona , USA , the monster esque plume of gas was held aloft by the ever-present but ever-changing magnetic field near the surface of the Sun. Our active Sun continues to show an unusually high number of prominences , filaments , sunspots , and large active regions as solar maximum approaches in 2025.
