What are the prominences?
Prominences are clouds of incandescent, ionized gas ejected from the Sun’s surface. They are also some of the most dramatic phenomena in the solar system, the equivalent of thousand-mile-high storms that can rage for months. This time-lapse film shows active prominences of a few hours’ duration.
What are the two types of prominences?
There are two basic types of prominences: (1) quiescent, or long-lived, and (2) transient. The former are associated with large-scale magnetic fields, marking the boundaries of unipolar magnetic regions or sunspot groups. Because the large unipolar plates are long-lived, the quiescent prominences are as well.
What are solar flares and prominences?
A prominence, seen from above and set against the Sun’s bright surface, appears as a dark filament. We also went over flares. A solar flare is a sudden, brief (typically lasting only a few minutes), and explosive release of solar magnetic energy that heats and accelerates the gas in the Sun’s atmosphere.
What is prominence of the Sun?
A solar prominence (also known as a filament when viewed against the solar disk) is a large, bright feature extending outward from the Sun’s surface. Prominences are anchored to the Sun’s surface in the photosphere, and extend outwards into the Sun’s hot outer atmosphere, called the corona.
How is a solar prominence created?
Prominences are shaped by the Sun’s complex magnetic field, often forming loops with each end “anchored” to the Sun’s surface (photosphere). Prominences are enormous, extending for many thousands of kilometers (miles). Prominences can last for several days – or up to several months!
How was the prominence of the Sun formed?
What do prominences affect?
Prominences are associated with the release of high energy particles, known as a solar flare. If a prominence breaks apart, it produces a coronal mass ejection. The solar flare aspect of a prominence has the most common effect on the earth.
What do solar prominences do to Earth?
If a prominence breaks apart, it produces a coronal mass ejection. The solar flare aspect of a prominence has the most common effect on the earth. Normally, the magnetic field surrounding earth deflects harmful solar radiation. If not, life would be impossible.
What causes a prominence?
How long are solar prominences?
A typical prominence extends over many thousands of kilometers; the largest on record was estimated at over 800,000 km (500,000 mi) long, roughly a solar radius.

What causes solar prominence?
solar prominence, dense cloud of incandescent ionized gas projecting from the Sun ’s chromosphere into the corona. Prominences sometimes extend hundreds of thousands of kilometres above the Sun’s chromosphere. Their causes are uncertain but probably involve magnetic forces.

What is the same about the Moon and the Sun?
When the Moon lies on a node, Earth, the Sun, and the Moon lie in the same plane. Rarely do the nodes line up exactly, but when they do — and if the Moon happens to be at new or full phase — total solar or lunar eclipses occur. However, due to the 5.1° tilt, eclipses do not occur every month.
