An analysis of astronomers

By Paul Scott Anderson in Space May 27, A new study concludes that a large, as-yet-unknown Planet Nine — an estimated 4 times the size of Earth and 10 times its mass — is influencing the behavior of an oddball object in the outer solar system.

Some astronomers work away from home temporarily at national or international facilities that have unique equipment. Astronomers held about 2, jobs in The largest employers of astronomers were as follows: The largest employers of physicists were as follows: Department of Defense have traditionally been two of the largest employers of physicists and astronomers in the federal government.

The scientific research-and-development industry includes both private and federally funded national laboratories, such as the Lawrence Livermore Laboratory in California, the Los Alamos National Laboratory in New Mexico, and the Goddard Institute in Maryland.

Job opportunities

Physics research is usually done in An analysis of astronomers or medium-sized laboratories. However, experiments in some areas of physics, such as nuclear and high-energy physics, may require extremely large and expensive equipment, such as particle accelerators and nuclear reactors.

Although physics research may require extensive experimentation in laboratories, physicists still spend much of their time in offices, planning, analyzing, fundraising, and reporting on research. Most astronomers work in offices and may visit observatories a few times a year.

An observatory is a building that houses ground-based telescopes used to gather data and make observations. Some astronomers work full time in observatories. Some physicists and astronomers work away from home temporarily at national or international facilities that have unique equipment, such as particle accelerators and gamma ray telescopes.

They also frequently travel to meetings to present research results, discuss ideas with colleagues, and learn more about new developments in their field. Work Schedules Most physicists and astronomers work full time.

Astronomers may need to work at night, because radiation from the sun tends to interfere less with observations made during nighttime hours.

Astronomers typically visit observatories only a few times per year and therefore keep normal office hours. How to Become a Physicist or Astronomer About this section Astronomers study planets, stars, galaxies, and other celestial bodies.

Physicists and astronomers typically need a Ph. After receiving a Ph. Graduate students usually concentrate in a subfield of physics or astronomy, such as condensed matter physics or cosmology. In addition to taking courses in physics or astronomy, Ph.

Computer science classes also are essential, because physicists and astronomers often develop specialized computer programs that are used to gather, analyze, and model data. Undergraduate physics programs provide a broad background in the natural sciences and mathematics. Typical courses include classical and quantum mechanics, thermodynamics, optics, and electromagnetism.

Students may choose to complete an internship during their undergraduate curriculum in order to gain additional hands-on experience. The American Astronomical Society has a directory of internships for astronomy students, and the American Physical Society lists internships for students in physics.

Students who do not want to continue their studies to the doctoral level may want to take courses in instrument building and computer science. Others may become science teachers in middle schools and high schools.

Training Many physics and astronomy Ph. During their postdoctoral appointment, they work with experienced scientists and continue to learn about their specialties or develop a broader understanding of related areas of research. Senior scientists may carefully supervise their initial work, but as these postdoctoral workers gain experience, they usually do more complex tasks and have greater independence in their work.

Important Qualities Analytical skills. Physicists and astronomers need to think logically in order to carry out scientific experiments and studies. They must be precise and accurate in their analyses because errors could invalidate their research. Physicists and astronomers present their research at scientific conferences, to the public, or to government and business leaders.

Physicists and astronomers write technical reports that may be published in scientific journals. They also write proposals for research funding. Physicists and astronomers must carefully evaluate their own work and the work of others.Astronomers believe that the interior of Saturn’s satellites is mostly ____.

Students will learn what spectroscopic data can specifically tell astronomers about the sun and other stars. 5. Students will observe a Doppler Shift and what it indicates about a celestial object. Spectroscopic analysis tells what elements the celestial object is burn-ing, if it is moving away or towards Earth, tells us its temperature.

Astronomy Tools - Spectroscopy: Spectroscopy is second to photography with regards to importance. It was the photography of spectra that birthed Astrophysics. The term spectra is defined as the entire electro-magnetic wavelength. Spectroscopy began in when Sir Isaac Newton discovered that white light passing through a glass prism split the light into a rainbow.

Spectrographs enable astronomers to study the spectrum i.e. energy emitted vs frequency of an astronomical object in great detail.
