Sun

To put it in layman terms, the Sun is simply a massive fusion engine that constantly emits energy into space. This fusion process is called stellar nucleosynthesis. The energy it produces amounts to incredible heat, approximately 383 billion megawatts multiplied by one billion. So why is the Sun so hot? Any machine that produces that

This is one of the most common questions thrown to astronomers and scientists. Many of us know that our Sun is a star and a star’s final moment is through a very powerful explosion known as a supernova. This is such a very dreadful scenario; however, the Sun will not experience the same fate as

So how much longer will the Sun be alive? Is it nearing its death? Is it still a baby in astronomical terms? Well, there is no need to worry because the Sun is going to be around for a few more billions of years. So we will be dead for millions and millions of years

What is the rotation of the sun? Every morning when people see the sun, most have no idea that it is rotating while the Earth and other planets revolve around it. When the Earth rotates, that is when people notice the change between night and day. So that means it takes 24 hours for the

In elementary science, you are taught that the Sun rises in the east. While this is an accepted generalized fact, you would be surprised to know that there are only two days out of the 365 days in a year when the Sun rises exactly on the east. These two days are the spring equinox

A sundog, bearing the scientific name parhelion (plural is parhelia) which means “beside the sun” in Greek, is also called a mock Sun or a phantom Sun. This is an atmospheric phenomenon that results to the manifestation of bright spots of light in the horizon. It usually appears in the form of a halo or

To put it simply, the Sun is as big as more than 1 million Earth masses put together. It is 1,287,000 times bigger than a solitary Earth. The Sun has a diameter of 1,392,000 km (865,000 miles) while the Earth’s diameter is only 12,742 km (7,918 miles). In terms of weight, the Sun is 333,000

In terms of its mass, the Sun has an enormous amount of it. It is a fact that the more mass an object has, the stronger its gravity will be. So given the Sun’s unusually huge mass, it also has an enormous amount of gravity. Here are the facts: the mass of the Sun is

Most pictures of the Sun depict it as a yellow heavenly body. The primary reason why the Sun appears yellow is the fact that it is made up of gases such as hydrogen and helium along with other elements like sulfur, magnesium, carbon, neon, iron, oxygen, nickel, chromium and calcium. The interaction of these elements
