Modern Astronomy is the astronomy in which we actually started looking at celestial bodies up close. Today there is a lot going on about the information of astronomy. Galileo was the first modern astronomer, just an interesting fact to throw in!
Astronomers are scientists who study celestial objects such as stars, planets, and galaxies, as well as the phenomena that occur in space. They use telescopes and other instruments to observe and analyze the universe to better understand its composition and behavior.
They study the Universe (also called the "cosmos".
More details: They study the structure and evolution of the Universe as a whole and try to find theories that explain the data.
At present the "Standard Model" they have developed is based on the "Big Bang Theory" of an expanding Universe. There are many different ideas consistent with the Big Bang. So, there's a lot more work required from cosmologists.
Man has always been curious about everything around him, everything he sees . This is how astronomy developed. Today, man has to answer the question, how big ist universe, how did everything come into existence, is it the end? Astronomy is used to answer these questions.
Astronomers are usually working for some kind of organisation like NASA or ESA where they are mapping the skies, so discovering new stars comets and galaxies. Astronomers do not earn alot of money they do it because they love it. However if they present a new and correct theory they will get it patented or something and that makes alot of cash. Some astronomers teach at an university. I think its also possible to receive some kind of fund for each new discovered and mapped celestial object. Basicly looking at the skies and making measurements is the daily astronomers job.
Typically, at universities. Relatively few astronomers actually WORK at the observatories they use. Astronomical observatories are generally at the tops of mountains, far away from the joys of the college campus. And with modern telecommunications and sophisticated computer-controlled instruments, there's no longer a need to press your eye against a frigid high-altitude eyepiece. It can all be controlled from your warm, cozy office in the flatlands.
And let's be truthful here; you CANNOT GET TO the best telescope, because the best telescope isn't here on Earth. It's the Hubble Space Telescope in orbit.
Astronomy is the study of the universe with particular reference to celestial bodies. The planets, the moons, the sun and other stars, galaxies, etc. all fall under astronomy. Astronomy is comparable to a physical geographic study of space. Not to be confused with astrophysics, the study of the physics or composition of celestial bodies.
Astronomy is the scientific study of celestial objects (such as planets, comets, stars, galaxies etc. that originate outside the Earth's atmosphere (such as cosmic background radiation). It is concerned with the evolution, physics, chemistry, meteorology, and the motion of celestial objects, as well as the formation & development of our universe.
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 trained 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. The number of professional astronomers in the United States is actually quite small. The American Astronomical Society, which is the major organization of professional astronomers in North America, has approximately 6500 members. This number includes scientists from other fields, such as physics, geology, and engineering, whose research interests are closely related to astronomy. The International Astronomical Union comprises almost 10,000 members from 87 different countries who are involved in astronomical research at the PhD level and beyond. While the number of professional astronomers world-wide is not much larger than the population of a small town, there is a huge community of amateur astronomers. Most cities have amateur astronomy clubs that meet on a regular basis and often host star parties in their communities. The Astronomical Society of the Pacific is the largest general astronomical society in the world, comprising both professional and amateur astronomers as well as educators from 70 different nations. Like any hobby, most people who think of themselves as amateur astronomers may devote a few hours a month to stargazing and reading the latest developments in research. However, amateurs span the range from so-called "armchair astronomers" to the very ambitious, who own science-grade telescopes and instruments with which they are able to make their own discoveries and assist professional astronomers in research.
Astronomy is the scientific field that studies the motion, size, composition, magnitude, etc. of matter beyond the earth's atmosphere. In simpler terms, it is the study of stars, planets, galaxies and other items in space, space itself and the universe.

Is a telescope a tool for astronomers?
A telescope is a tool for atronomers. Yes!
Atronomers believe that the solar system is about how many years?
Astronomers believe that the solar system is about 4.6 billion years old. This age is determined by studying the ages of rocks on Earth and meteorites from space that have been dated using radiometric dating techniques.

How does atronomers live on moon?
They don't. Astronomers are people who study the cosmos from....earth!
What are some of the things atronomers can learn about astronomical objects from their spectra?
The main physical information about astronomical objects give their spectra!

What is a astronomer specializes in?
An astronomer specializes in studying celestial objects such as planets, stars, galaxies, and cosmic phenomena. They use telescopes, satellites, and computer simulations to observe, analyze, and interpret data to better understand the universe and its origins.
How do atronomers detect dark matter?
Gravity. We cannot see or directly detect "dark matter", and the only reason why astronomers talk about "dark matter" is that galaxies like the Milky Way appear to be spinning too fast for gravity to hold them together. Or at least, for the gravity of the mass that we can SEE to hold them together. Gravity comes from matter, and we can't see enough matter, so it must be "dark matter". This may be in the form of trillions of invisibly-dim brown dwarf stars, or in black holes from which no light ever escapes - or it may be something entirely new. "Dark matter" is the something new.
How do astronomers plot a star's exact position?
Astronomers use a coordinate system called Right Ascension and Declination to plot a star's exact position on the celestial sphere. Right Ascension (measured in hours, minutes, and seconds) defines the star's east-west position, and Declination (measured in degrees) defines its north-south position. By triangulating these coordinates, astronomers can accurately pinpoint a star's location in the night sky.
