Discover how stars are classified based on different observable characteristics, such as spectral class and luminosity class. Learn what type of...
Color Astronomers classify stars according to their physical characteristics which include; color, temperature, size, composition, and brightness. Looking up at the night sky you will notice that some stars look reddish, while others are yellow or blue-white. Differences in the colors of stars are...
AstronomerEdwin Hubbleled the way to classify celestial giants called galaxies.Galaxiesare a system of stars, interstellar gas,dark matter, dust, and stellar remnants that are gravitationally bound together. Through his observations, Hubble categorized galaxies into three primary classifications:spiral,ellip...

The article seeks to classify medieval astronomical tables compiled in Europe by means of their content and internal structure. The author first classifies these tables according to their themes, which include chronology, trigonometry and spherical astronomy, and precession and apogees, as well as ...
It was a term that was brought in by the music industry to classify music that is neither Jazz, classical, pop, or rock. They didn’t know what to call it or what to do with it. So they threw it all together under this one name.”– Yanni. Yanni is one of the most famous New...
indirect information related to solar activity is used. We classify this information into two categories: historical records and modern measurements of quantities that are correlated to solar activity. The first category includes sunspot number: the 11 year solar-cycle length, the aurora’s frequency ...
(USA) plotted absolute brightness of stars and their temperature to show their relationship. Astronomers use H-R diagram to classify stars and understand how stars change over time. 90% of stars are main sequence (found in diagonal area from lower right to upper left) where surface temperature...
