Front

What is a sunspot?

Back

A sunspot is a dark spot on the photosphere of the sun, caused by magnetic activity that inhibits convection, resulting in lower temperatures compared to surrounding areas.

Front

What is solar minimum?

Back

Solar minimum is the period in the solar cycle when the sun has the least number of sunspots and solar activity is at its lowest.

Front

What is solar maximum?

Back

Solar maximum is the period in the solar cycle when the sun exhibits the highest level of solar activity, characterized by a large number of sunspots.

Front

What are solar flares?

Back

Solar flares are sudden eruptions of energy on the sun's surface, often associated with sunspots, that release a large amount of radiation.

Front

What are coronal mass ejections (CMEs)?

Back

Coronal mass ejections are significant releases of plasma and magnetic field from the solar corona, often associated with solar flares and sunspots.

Front

What is the solar cycle?

Back

The solar cycle is the approximately 11-year cycle that describes the fluctuation in solar activity, including the number of sunspots and solar flares.

Front

What is the sun's corona?

Back

The sun's corona is the outermost layer of the sun's atmosphere, visible during a total solar eclipse, and is much hotter than the surface.

Front

What is solar wind?

Back

Solar wind is a stream of charged particles released from the upper atmosphere of the sun, which can affect space weather and Earth's magnetosphere.

Front

What is the relationship between sunspots and solar flares?

Back

Sunspots are often the sites of solar flares; increased sunspot activity can lead to more frequent and intense solar flares.

Front

How do sunspots affect Earth?

Back

Sunspots can influence space weather, affecting satellite operations, communication systems, and even power grids on Earth.
