Though the universe is filled with billions upon billions of stars, the discovery of a single variable star in 1923 altered the course of modern astronomy. Amateur astronomy is a hobby where participants enjoy observing or imaging celestial objects in the sky using the unaided eye, binoculars, or telescopes.Even though scientific research may not be their primary goal, some amateur astronomers make contributions in doing citizen science, such as by monitoring variable stars, double stars sunspots, or occultations of stars by the Moon or asteroids ... Galaxy: Galaxy, any of the systems of stars and interstellar matter that make up the universe. Many such assemblages are so enormous that they contain hundreds of billions of stars. Virtually all galaxies appear to have been formed soon after the universe began, and they pervade all space that is viewable by modern telescopes.

Stars great and small, and their life cycles. A star’s color is critical in identifying the star, because it tells us the star’s surface temperature in the black body radiation scale.The sun has a surface temperature of 5,500 K, typical for a yellow star. Red stars are cooler than the sun, with surface temperatures of 3,500 K for a bright red star and 2,500 K for a dark red star. download Study Of Variable Stars Using Small Telescopes in pdf BEST Study Of Variable Stars Using Small Telescopes PDF NASA Sol, the model for finding stars with habitable planets. Notable Extra-Solar Planets. Over the past several years, astronomers increasingly have been using three, somewhat overlapping, terms to describe a range of extra-Solar planets that have been, or may soon be, found.
