What is the name for jets of gas which extend upward from the chromosphere?

spicules
The chromosphere of the Sun observed through a telescope with a filter that isolates the H-alpha emission. The most prominent structures in the chromosphere, especially in the limb, are the clusters of jets, or streams, of plasma called spicules. Spicules extend up to 10,000 kilometres above the surface of the Sun.

What are large clouds that rise from the chromosphere?

The most common feature is the presence of spicules. Spicules rise to the top of the chromosphere and then sink back down again over the course of about 10 minutes. Similarly, there are horizontal wisps of gas called fibrils, which last about twice as long as spicules.

What layer of the sun is the chromosphere?

photosphere
The chromosphere is above the photosphere, the visible “surface” of the Sun. It lies below the solar corona, the Sun’s upper atmosphere, which extends many thousands of kilometers above the chromosphere into space. The plasma (electrically charged gas) in the chromosphere has a very low density.

What is the eruption of gases from the chromosphere?

Solar flares are sporadic local eruptions of the chromosphere. They develop suddenly and rapidly, in minutes, and cover a relatively small region of the solar surface. Initially they manifest themselves by a localized sudden brightening. The duration of a solar flare ranges from about 20 minutes to as much as 3 hours.

How far does the sun’s corona extend?

All NASA Missions Now, using NASA’s Solar Terrestrial Relations Observatory, scientists have found that this atmosphere, called the corona, is even larger than thought, extending out some 5 million miles above the sun’s surface — the equivalent of 12 solar radii.

What does the corona of the sun do?

The corona is in the outer layer of the Sun’s atmosphere—far from its surface. Yet the corona is hundreds of times hotter than the Sun’s surface. In the corona, the heat bombs explode and release their energy as heat. But astronomers think that this is only one of many ways in which the corona is heated.

What happens in chromosphere?

NASA/Marshall Solar Physics. The chromosphere is an irregular layer above the photosphere where the temperature rises from 6000°C to about 20,000°C. At these higher temperatures hydrogen emits light that gives off a reddish color (H-alpha emission).

What is chromosphere and photosphere?

Definition: Chromosphere is a reddish and glowing layer of gas above a star’s (or Sun’s) photosphere. Out of the three layers of the Sun’s atmosphere, chromosphere is the second one (with photosphere being the first layer and corona as the third).

How big is the chromosphere of the Sun?

The chromosphere is 2000-3000 km thick and the temperature rises from around 6000k to 20,000K.

How is the chromosphere affected by a solar eclipse?

The image to the left of a total solar eclipse demonstrates the colouring of the chromosphere. The chromosphere contains spikes of gas called spicules that rise through it. Spicules are short-lived phenomena, corresponding to rising jets of gas that move upward at about 30km/sec and last only about 10 minutes. The Corona

How are hot and cold gas bubbles related?

The hot bubbles rise quickly to higher levels, cooling and expanding, just like hot air rising in the atmosphere of the earth. When it becomes cooler that its surroundings, the gas sinks to become reheated and rise again. In this way rolling currents of hot and cold gas create a churning motion that carries heat from the bottom to the top.

Is the photosphere the source of solar flares?

The photosphere is also the source of solar flares: tongues of fire that extend hundreds of thousands of miles above the sun’s surface. Solar flares produce bursts of X-rays, ultraviolet radiation, electromagnetic radiation and radio waves. The next layer is the chromosphere.
