She discovered the Cepheid variable, a group of giant variable stars with luminosities 500-30,000 times greater than that of the Sun. Henrietta Swan Leavitt is considered the pioneer in galactic astronomy. Once we better understand Milky Way, we’ll have a better idea of the origin and evolution of other local groups of galaxies. This field won’t just help us understand our own galaxy. Astronomers who study galactic astronomy, or galactic cosmology, focus on the chemical and stellar evolution, star formation, and motion of the Milky Way. Planet Earth is inside Milky Way, a galaxy spinning around a massive black hole. She is credited to the development of the Stellar Classification system, where the stars are classified according to the temperature they produce, their size and color. Stellar astronomers investigate how the stars are born, what constituents they have, how they evolve over their long lifespans, and what happens when they die.Īnnie Jump Cannon is considered one of the earliest stellar astronomers. Stellar astronomy is the study of the Sun and the stars. READ: 35 Impressive Facts About the Planet Mercury 3. He suggested the heliocentric theory which states that the Earth revolves around the Sun. Nicolaus Copernicus is regarded as the first solar astronomer. They may also research how the sun affects us here on Earth. Solar astronomers study the systems and characteristics of the Sun, such as its atmosphere, magnetohydrodynamics, solar winds, radiation, and more. This branch of astronomy focuses specifically on the yellow star Sol, often called the Sun. Galileo Galilei is one famous planetary astronomer and he is called the Father of Observational Astronomy. They also investigate the cosmological prerequisites required to form new planetary bodies and the possibility of life in them. Astronomers in this field study planetary & exoplanetary atmospheres, surfaces, and exteriors of planets and the distribution of planets around other stars. Planetary astronomy is the study of planets and planetary bodies, including moons, comets, and asteroids. Enlisted below are some of the popular branches of astronomy. There are a vast number of celestial objects that astronomers study, that it is convenient to break astronomy up into different branches. Astrology is not a science and is no longer recognized as something that has to do anything with astronomy. Combining, astronomy means “star law”.Īstronomy should not be confused with “astrology.” The latter is the study dealing with the movements and relative positions of celestial bodies and their influence on human affairs. The word comes to us from the ancient Greek words, “Astro,” which means “star,” and “nomos,” which means “law”. It is also the oldest of the natural sciences. Astronomers observe and study galaxies, planets, stars, comets, meteors, and various phenomena involving the objects in space. I glanced at her and said, "Nice shooting back there.Astronomy is the scientific study of all celestial objects. I glanced at her and said, "Nice shooting back there." He's chasing us-out into the open water." She thought a moment, then said, "In other words, we're not chasing him anymore. She replied, "I have nine left in this magazine and a full magazine of fifteen in my pocket." She pointed and said, "That must be Long Beach Bar Lighthouse over there." I asked her, "How many rounds do you have left?"īeth found the plastic-coated chart on the deck and unfolded it on the dashboard. I set a course that would take us to the right of the lighthouse out into Gardiners Bay, which in turn would put us on a course to Plum Island. "Right." She glanced back over her shoulder and said, "He's got us outgunned and outboated."Ĭorrect. Jeez Just like old times back in the city." I asked her, as an afterthought, "You okay?"īeth folded her chart. ![]() I said to her, "I heard that last round go past my ear before it went through the windshield. ![]()
