Front

What is the solar cycle?

Back

The solar cycle is the cycle that the Sun’s magnetic field goes through approximately every 11 years, characterized by the increase and decrease of sunspots.

Front

What is a solar flare?

Back

A solar flare is a sudden eruption of increased brightness on the Sun, often associated with sunspots and magnetic activity.

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.

Front

What is solar minimum?

Back

Solar minimum is the period in the solar cycle when the Sun has the least number of sunspots.

Front

What is solar maximum?

Back

Solar maximum is the period in the solar cycle when the Sun has the most sunspots and solar activity is at its peak.

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.

Front

What is a coronal mass ejection (CME)?

Back

A coronal mass ejection is a significant release of plasma and magnetic field from the solar corona, often associated with solar flares.

Front

What is the photosphere?

Back

The photosphere is the visible surface of the Sun, from which light is emitted.

Front

What is the Sun's corona?

Back

The Sun's corona is the outermost layer of its atmosphere, visible during a total solar eclipse, and extends millions of kilometers into space.

Front

How do sunspots affect Earth?

Back

Sunspots can influence solar radiation and solar wind, which can affect satellite operations and communications on Earth.
