What are dark areas on the photosphere on the sun called?
Dark areas on the photosphere of the Sun are called sunspots. They appear dark because they are cooler regions compared to their surrounding areas, which results in decreased luminosity. Sunspots are temporary phenomena that occur in 11-year cycles as part of the Sun's magnetic activity.
What are the dark spots on the photosphere?
Dark spots on the photosphere, known as sunspots, are areas of reduced surface temperature caused by magnetic activity on the Sun. They appear darker than their surroundings because they are cooler and emit less light. Sunspots can vary in size and number over an 11-year solar cycle.
What structure found in the photosphere?
Sunspots are structures commonly found in the photosphere of the Sun. These dark regions are caused by magnetic activity and are cooler than the surrounding areas, hence appearing dark against the brighter photosphere. Sunspots often occur in pairs with opposite magnetic polarities.
What are the surface features of sun?
Photosphere- outer (gaseous) layer or surface of sun that we see Faculae- bright areas Sunspots- dark areas
What are the suns surfaces features?
Photosphere- outer (gaseous) layer or surface of sun that we see Faculae- bright areas Sunspots- dark areas
An area seen as a dark spot on the photosphere of the sun?
The darkest part, where the magnetic field is approximately vertical to the sun's surface is called the Umbra.
What are dark spots on photosphere called?
The black spots on the photosphere of the sun are called sunspots.
Why is the center of a Sunspot dark?
It is not actually dark, it is just dark in comparison to the rest of the Sun's photosphere. This is because the magnetic fields/flux associated with the sunspot inhibit convection and therefore reduce the amount of heat rising from below where they are present.
An area seen as dark spot on the photosphere of sun?
A "sunspot."
Where can you find sunspot?
Sunspots can be observed on the surface of the Sun. They appear as dark, cooler areas compared to their surroundings due to magnetic activity suppressing convection. Sunspot activity follows an 11-year cycle and can be observed using solar telescopes equipped with proper filters for safe viewing.
What are dark spots called on the photosphere called?
The black spots on the photosphere of the sun are called sunspots.
Is a sunspot a dark patch on the sun?
Yes, a sunspot is a dark patch on the Sun's surface, appearing darker than the surrounding areas. This occurs because sunspots are cooler regions within the Sun's photosphere, with temperatures typically around 3,000 to 4,500 degrees Celsius, compared to the surrounding areas which are about 5,500 degrees Celsius. Sunspots are associated with magnetic activity and can influence solar phenomena such as solar flares and coronal mass ejections.
