What does an astrophysicist do, exactly?
106743
Astrophysicist study and experiment with the forces and material reality of space and the universe.  Some may study gravity, electomagentic effects, how particles are affected by forces, some may study dark matter and dark energy, and some may study the cosmic background radiation.  Astrophysicist study the very energies and particles and force that make up our universe.

If you whole heartedly like and do what you do then not only Astronomy, any job is a fun job. When you do such a fun job time flies. Astronomy is sure one such profession, where you will never feel tired of it. While optical astronomers observe in the night, the radio astronomers observe celestial sources both in the day and night. Rain, Clouds, Sunlight don't affect the observations of radio sources. Similarly astronomy in other frequencies of observations such as Gamma ray, X-ray, Ultraviolet, Infrared and microwave each have different types of advantages and restrictions.\n\nAstronomy is one of the oldest professions in the human society.\nModern day equipments and computers have made the astronomical observations much easier now than it used to be in the past.

What does this have to do with astronomy?

I assume you are speaking of astrophysics because all of the other fields are easy to discern. \nI cannot remember what physicist said it but one of them said that Discovery and hope are good for the soul. For me that is very true.

The way to measure it is to measure the redshift of galaxies at different distances. Are they starting to slow down, or not? But like was said above, I'm not going to worry about it. Not that cosmology isn't a fun thing to study, but as far as applications it's just about there with Abstract Art. I would say let's concentrate on applied physics, earth and solar science first, develop some new technologies, maybe colonize Mars, some other solar systems, or a good fraction of the galaxy and then we can worry about the fate of the universe when we have more tools, power and understanding to explore or do something about it. It's noble and admirable, but might be like a caveman pondering the lifespan of the sun - that large bright circle that goes around the flat earth. Occasionally skipping ahead is rewarded - most times it's a shot in the dark.

Actually, contrary to popular belief, most astronomers do NOT stay up all night. In some cases one does (typically if you go to an observatory), but when you are observing with radio telescope arrays or satellites you can essentially e-mail in your observatons and then sit back and watch TV while they're being done. (You can't just send an text e-mail with your requests, you have to work with some fairly complex software to generate the observing information.)\n\nMost of the time for astonomers is spent back at their home institution in front of a computer. That is where all the information from telescopes, satellites or whatnot are analyzed using a wide variety of specialized software packages. That data analysis almost always takes a lot longer than the actual observations.\n\nThen you have to write it all up and show how your data is either just darn interesting, or fits with an established theory, or - if you're lucky - doesn't fit with an established theory.\n\nBut the process for doing this can take months or years. Rarely is anyone in modern science, not just astonomy, working alone. You need to get input and help from your colleagues (and help them when they are taking the lead in writing up papers).\n\nYou need to send the paper in to be printed, realizing that if it is in a hot field it had better be old news by the time the actual print copy appears. You need to send your finished paper out to friends and others in the same sub-field. Post it one electronic document-servers for astronomy and physics. And also go to either specialised or general astronomy conferences. The American Astronomical Society has two big conferences a year. At the confernes you need to meet other people and start to cross connect information as well as promote your own ideas.\n\nLet's see, you also have to write grants. Getting grants for telescope or satellite time is often not that hard. You have to be able to scientifically justify your observations and don't get everything, but it is not terribly difficult to build up more data than you can use in a couple of years. The hard past --- and this is critical --- is that it is much harder to get grant money. If you are a postdoc you may need a lot of grant money just for your salary.\n\nOn top of that, many astronomers have to do something else. Often it is to teach a couple of classes at a university. Or, if you are working at some place like the National Radio Astronomy Observatory you need to work on the various software packages and routines that you and others use to process and analyze data.\n\nAnd on top of that you need a job. My own experience was more or less typical (I was a radio/X-ray astronomer for about a decade after grad school).\n\nAfter college there were 4 more years of grad school in physics (about half of all astronmers have physics degrees). I actually finished slightly faster than some. Then I had two 1-year teaching positions as a Visiting Professor. After that I got a 2-3 year postdoc at Penn State. It turned out to last for 6 years, except that wasn't obvious at the time and except for one year I spent a lot of time looking for a permanent position. I got one, finally, and went the astronomy group at Fermilab outside of Chicago.\n\nNote that by this time others that I had known in college, even some slow ones, had houses and were well established into careers. Boring ones, but careers none the less. We (myself + wife + kid) were still renting and while my salary was okay, it wasn't particually impressive for the amount of effort that had gone into the whole process.\n\nAnd I ended up not liking the work at Fermilab a whole lot (turns out I had a brain tumor - but that's another story).\n\nSo after 2 years at Fermi I, very, very reluctantly left science for various computer and technical writing jobs with various business entities. I make more money, do a lot less work, and still at times regret having to leave science sometimes.\n

They have specialist called meteorologist who use special technology that connects to satellites that are orbiting the air and picking up waves from the atmosphere. There are several parts to the atmosphere so the also use special kinds of barometers. To make a long story short it's all in technology.

Astronomy is generally considered a subfield of physics, although it is distinct from the related field of astrophysics.  (One way of differentiating between astronomy and astrophysics is that astronomy deals with what stars do and astrophysics deals with how/why they do it.)  \n\nAlthough there are a number of universities which grant bachelor's degrees both in physics and in astronomy, the curricula typically overlap and a basic physics degree will prepare one for graduate school.  The basic physics curriculum includes a heavy dose of mathematics as well as classes within the field of physics--classical mechanics, quantum mechanics, electromagnetism, electronics, atomic & nuclear physics, thermodynamics, optics.  A concentration in astronomy would also include an observational astronomy class, celestial mechanics, and more optics.\n\nA Ph.D. is typically required to work in the field of astronomy, although there are some "low-level" jobs available with a master's degree.  Advanced degrees in physics, including astronomy, can take anywhere from three to ten years to earn.  The main reason for the variation in the time to complete a degree is because of the research required for a doctoral thesis.  Getting time on a major telescope or array to collect data can be difficult and there's always the possibility of being bumped by someone with more pull.  The nature of research generally can mean several months of work can be wrecked or rendered useless in a heartbeat.  There are a number of excellent schools for astronomy--Arizona, Cornell, Chicago, Maryland, Iowa State, North Carolina State, New Mexico, just to name a few. \n\nAs to whether meteorology or astronomy is better for society, well, that depends on your criteria.  Meteorology probably has many more direct and practical applications and impact on individuals.  Space science generally has brought a number of advances in technology/convenience.  Learning more about the natural world around us, specifically the lights in the night sky, however tends to inspire the poet and dreamer in folks, reminding us of the things that are greater than we ourselves.\n\nOh, and I can't speak to preparation for meteorology, so I won't. \n\n******\nI have a B.S. in physics with minors in mathematics and philosophy, spent a year in graduate school for physics (Ph.D-track) and studied the history of science before pursuing other things.

Many physicists go into information technology professions. I have seen quite a few, ranging from PhDs and bachelors, working in IT consulting, teaching, programming, and all sorts. It seems that stuff learnt in physics lectures can be translated into IT work too.

astrology \n\nA study of the positions and relationships of the sun, moon, stars, and planets in order to judge their influence on human actions. Astrology, unlike astronomy, is not a scientific study and has been much criticized by scientists. (See zodiac.)

Not really. There are some internships if you want a job, but they are not going to listen to theories of just any random teenager who walks in the door. If you really do have a good theory, get it published in the appropriate scientific journal, like Nature or the Astrophysical Journal. Then NASA might pay some attention to it.

Elaborating on strangeberry's; try to do some of your research in grad school with NASA staff.  There are grad student fellowships. The GSRP listed below is an excellent way to do this.  Try to attach yourself as a grad student to a faculty member who has had several students win them.  As a grad student, I saw students of certain faculty win them over and over and over again, so I think it helps to be with one of these "in" faculty. \n\nI am sure NASA has public stats on who wins them and what universities they attend so I would look for that info starting at the link below and pick your grad school and advisor based on what you find.  If that fails, then picking a school physically near a NASA center (like Ames or Goddard) is a good fallback. I have another link below listing all the centers. Good luck!\n\n(BTW, if you mostly just want to work for NASA and the Physics or Astrophysics PhD is beyond your reach, they also like engineers! Contact me directly if you want some tips on going that route.)

In practice most of these branches of physics employ both theorists and experimentalists. Occasionally an individual wears both hats.\n\nCondensed Matter Physics \nThis is the study of matter when there are large numbers of particles in close proximity. Ordinary solids are the most common example. This research lead to the first transistor and to today's high capacity storage media. But the field also includes many esoteric forms of matter, from Nutronium (the substance of neutron stars) to matter confined to one or two dimensions. Recent work has produced samples numbering in the tens of thousands of atoms that all behave according to a single wave function (the atoms have lost their individual identities). These collections are called Bose-Einstein Condensates (BEC) and form a new category of matter. \nAtomic and Molecular Physics \nIndividual atoms or small groups of atoms are the focus in this field. Some researches use single trapped atoms to make extremely precise measurements to confirm theories about Quantum Mechanics or Relativity. Others are exploring the interaction between atoms (or molecules) or the interaction between light and atoms. Lasers and laser physics are an important part of this research area. \nNuclear Physics \nAs the name implies, this field examines the nucleus of the atom. While the composition of the nucleus is understood for all atoms and their isotopes, the arrangements and interactions of the nuclear constituents is still a rich field of study. Nuclear physics includes the fission and fusion reactions that provide nuclear power, as well as the nuclear synthesis process that fuels the sun and other stars. \nHigh Energy Particle Physics \nThis is where the theories about the fundamental structure of nature are devised. They are then tested at high energy accelerator laboratories and in the study of cosmic rays. Theories about the smallest particles and the largest structures in our universe have become linked by the Big Bang Theory. Many High Energy Physicists also do work in Cosmology. \nMathematical Physics \nHistorically physics and mathematics grew up together, each field pushing the other into new realms. The mathematical physicist works on the border between math and physics to help us find a rigorous description of nature. Some of the most subtle and profound ideas in physics were created here. \nPhysics Education Research \nThis is a relatively new field in physics departments. The practitioners are physicists who observe students learning physics and examine the difficulties encountered. Their work is changing the face of the college physics course nationwide. \nInterdisciplinary research \nA growing number of departments support degree candidates who want to straddle two disciplines in their research. Topics like these at UIUC are indicative of the programs available. Here again your best search strategy is to visit the graduate programs, select a particular physics department, and search that site for research topics.

All of them are sciences or Arts. . But people master these subjects by reading books, or practice under a teacher of directly. There is not institution to teach these. But about 80 % of the person who are doing this are fake and take advantage of the people who are suffering in their lift for some thing or other and they look upon someone who give word of encoragement through these subect. The actual meaning of these sciences are -\n\nASTROLOGY - Astrology is a group of systems, traditions, and beliefs in which knowledge of the relative positions of celestial bodies and related information is held to be useful in understanding, interpreting, and organizing knowledge about personality, human affairs, and other terrestrial events. A practitioner of astrology is called an astrologer, or, less often, an astrologist. Historically, the term mathematicus was used to denote a person proficient in astrology, astronomy, and mathematics. Although the two fields share a common origin, modern astronomy is entirely distinct from astrology. While astronomy is the scientific study of astronomical objects and phenomena, the practice of astrology is concerned with the correlation of heavenly bodies (which historically involved measurement of the celestial sphere) with earthly and human affairs. Astrology is variously considered by its proponents to be a symbolic language, a form of art, science, or divination. The scientific community generally considers astrology to be a pseudoscience or superstition as it has failed empirical tests in controlled studies.\n\nPALMISTRY - Chiromancy or cheiromancy, (Greek cheir, “hand”; manteia, “divination”), is the art of characterization and foretelling the future through the study of the palm, also known as palmistry, palm-reading, chirology or hand analysis. The practice is found all over the world, with numerous cultural variations. Those who practise chiromancy are generally called chiromancers, palmists, palm readers or chirologists.\nModern palmistry can trace its roots back to Roma fortune tellers and Indian mystics, but often modern palmists combine traditional predictive techniques with psychology, holistic healing, and alternative methods of divination.\n\nTAROT CARDS - The tarot are a set of cards displaying allegorical representations originally used as playing cards and later for divination. Most modern tarot decks consist of 78 cards split into two major groups:\nThe major arcana, consisting of 22 trump cards (sometimes referred to as keys):

If you are planning on going to college for four years, getting a bachelors' degree and getting a real job having anything at all to do with physics, forget it. \n\nIn order to get a real job in physics, let alone astrophysics, four years of post high school education isn't going to do it. You will need a PhD, and a Masters degree at the very least. And yes, those will require math, and a lot of it.\n\nIf you can deal with the math part, then go for it. Otherwise I would suggest finding a similar major that you do like, such as a science degree of some sort, and declare a minor in physics. This will minimize the math requirements.
