What makes plasma rain on the surface of the Sun?

As the film progresses, huge loops of solar material fall down to the solar surface, a flare-driven occurrence known as post-flare loops or coronal rain. These loops become filled with particles that are accelerated to high energies by the turbulence they create as their weight causes them to collapse.

The particles in these clouds are electrically charged and it is this charge that causes them to be deflected by the Earth's magnetic field towards the surface. When they reach the atmosphere they can either dissipate their energy by collision with other molecules or radiation, or they can pass through the atmosphere without incident.

Plasma is made up of ionized particles that are driven apart by electrical forces; therefore, plasma is conductive but not metallic. The Sun is composed mainly of plasma, so it isn't surprising that it has such an impact on Earth's environment. For example, the aurora are caused by particles from the Sun entering the Earth's atmosphere and being absorbed into its magnetic field.

The most energetic events occur when a filament or sheet of solar material breaks off from the rest of the Sun and falls toward the surface. If it reaches the surface before breaking up, it will form a new sunspot. Less energetic events may only cause a cloud to ripple across the surface of the Sun for a few days before disappearing.

What are the huge loops of plasma erupting from the sun called?

Coronal loops are massive magnetic field loops that begin and finish on the Sun's visible surface (photosphere) and extend into the solar atmosphere (corona). The loops are visible because they are filled with hot, luminous ionized gas (plasma).

When a coronal loop is stressed by forces from within, it can snap. If the stress is great enough, it will be more efficient to break than to hold its shape, so the loop will collapse down onto itself until the tension in the magnetic field is less than the force of gravity. At this point, the loop will rebound outwards, stretching to its limit before snapping again. This cycle continues until no more snaps can be achieved, at which point the loop will collapse under its own weight.

The Sun's corona is made up of billions of these collapsed loops. When a loop collapses, it emits radiation at all wavelengths from radio waves to x-rays and beyond. Some parts of the emitted spectrum are visible to us from Earth while others are not. Thus, we call these phenomena "cosmic rays".

The Sun goes through an activity cycle. As it approaches the maximum of its cycle, many regions on the photosphere become excited and emit radiation at wavelengths we can see. These regions are known as active areas. Eventually, all active area will dissipate and be replaced by new ones.

Why does it rain in the sun?

Huge droplets of plasma, or electrified gas, can fall onto the searing surface from prominences (huge magnetic loops of gas) in the sun's outer atmosphere, the corona. This uncommon phenomena, known as coronal rain, was the focus of a NASA undergraduate student's research, who wished to better chronicle it. The student used data from the Solar Terrestrial Relations Observatory (STEREO), which is a pair of satellites that orbit the planet about 16 minutes apart, and study the sun from two different angles. The STEREO mission is part of the Solar Dynamics Observatory (SDO), which is a satellite launched by NASA in 2010 to study the sun in 3D with high-resolution images and videos.

Coronal rain has been observed by several space missions over the years. It was first discovered by NASA's Skylab spacecraft in 1973. Since then, it has been seen on the Sun during major solar storms when clouds of electrons and ions are blown into space from the corona. Coronal rain falls back down toward the Sun's surface because gravity points southward at both Earth and the Sun. Thus, any particles falling towards Earth from the storm would travel south of west across our planet, while those falling towards the Sun would do so east of north.

Coronal rain occurs when charged particles from the corona hit the top of the sun's atmosphere, called the photosphere.

What are magnetic storms on the sun’s surface called?

Solar flares are brilliant blasts of radiation produced by magnetically active areas on the sun's surface. When the sun's magnetic fields get twisted and knotted, massive bursts of energy may be sent hurtling toward Earth in a matter of minutes. These violent events can cause power outages and satellite damage, but they also provide us with valuable information about our star. Solar flares were first discovered visually in 1848, when astronomer Richard Carrington recorded seeing stars before and after a solar flare occurred.

Nowadays, we detect them using satellites and other instruments. Solar flares can emit particles that reach Earth's atmosphere to create conditions similar to those inside a planetarium. In fact, cosmic rays are the primary source of data on solar activity used by scientists to develop models that can predict future eruptions with greater accuracy.

The connection between solar activity and terrestrial effects was noted as early as 1715 by British astronomer Charles Mason, who observed that stars appeared to be changing position in the night sky during periods when wars were being fought on Earth. Since then, many other correlations have been found between solar activity and various terrestrial effects. Some of these connections are discussed below.

Magnetic storms on the sun's surface are known as sunspots.
