Basic Astronomy News

Easier - Astronomy is the study of things found in space such as the sun, planets, moons, and stars.

Advanced -Astronomy , one of the oldest sciences, is the study of celestial bodies such as planets, stars, and other objects in space. Astronomers locate objects in the daytime or nighttime skies and measure their magnitudes and motions, searching to find what they are made of and how they create their light.

An astronomer is a scientist who studies celestial bodies such as planets, stars, and galaxies. Historically, astronomy was more concerned with the classification and description of phenomena in the sky, while astrophysics attempted to explain these phenomena and the differences between them using physical laws. Today, that distinction has mostly disappeared. Professional astronomers are highly educated individuals who typically have a PhD in physics or astronomy and are employed by research institutions or universities. They spend the majority of their time working on research, although they quite often have other duties such as teaching, building instruments, or aiding in the operation of an observatory.

Solar astronomy : Main article: Sun At a distance of about eight light-minutes, the most frequently studied star is the Sun, a typical main-sequence dwarf star of stellar class G2 V, and about 4.6 Gyr in age. The Sun is not considered a variable star, but it does undergo periodic changes in activity known as the sunspot cycle. This is an 11-year fluctuation in sunspot numbers. Sunspots are regions of lower-than- average temperatures that are associated with intense magnetic activity. Astronomy brief news.
