The polar opposite of the Sun’s solar maximum period is the solar minimum. In the Sun’s eleven year cycle, the solar minimum is the period when there is least solar activity, as contrasted to the solar maximum, when solar activity is at its peak. It is during this period that the occurrence of sunspots, coronal

Sunsets are usually associated with the color red and in some cases, can be seen with a tinge of orange. Why is the sunset red? Sunlight is composed of various colors of light, with each carrying a different wavelength. As the Sun sets, more red colored light is scattered towards the direction of the Earth

In science, sunlight may be defined as the total frequency spectrum of the electromagnetic radiation that is emitted by the Sun. On earth, the atmosphere filters the sunlight before it touches the surface. When the Sun can be seen in the horizon, there is visible evidence of its radiation. This is commonly known as sunlight

The Sun is not a constant, unmoving mass of plasma and energy. It is constantly active, sometimes releasing sudden amounts of energy and displaying different kinds of solar activity. These patterns of activity are believed to be driven by the surface magnetism of the Sun, underneath which rotation and convective flows arise. The amount of

Everybody knows that the path of the Sun is from east to west. It rises from the east and then sets on the west. This cycle will go on and on every day. But does it always follow the exact same path every day? Does the axis of our planet have any significance with the

Are there really rings around the sun like the planet Saturn? When a person stares at the sky, sometimes they see a ring around the sun. But most people haven’t seen those rings before. The rings that encircle the sun make people curious of what causes it to appear and disappear all of a sudden.

To better understand how old the Sun is, it is important that we learn what a star’s life cycle is like. The Sun is a star and stars have life cycles that depend on their masses. The Sun starts off as a super giant cloud that is made of cold molecular hydrogen. A passing star,

Solar irradiance is an astronomical term which is used to refer to the amount of energy emitted by the Sun over all wavelengths that fall per second on 11 sq ft outside the Earth’s atmosphere. In simpler terms, it is the amount of radiant energy coming form the Sun which human beings are able to

The sun is definitely huge compared to other objects in the solar system. It is big enough to consume all the planets inside it. It even makes up 99% of the entire mass of the solar system. The mass of the sun is 1.9891 x 1030 kg. Making it simple, imagine that it is 333
