Visit the Ringed Planet Saturn

Visit the Ringed Planet Saturn The Beauty of Saturn Saturn is the sixth planet from the Sun and among the most beautiful in the solar system. Its named after the Roman god of agriculture. This world, which is the second largest planet, is most famous for its ring system, which is visible even from Earth. You can spot it with a pair of binoculars or a small telescope fairly easily. The first astronomer to spot those rings was Galileo Galilei. He saw them through his home-built telescope in the year 1610. From Handles to Rings Galileos use of the telescope was a boon to the science of astronomy. Although he didnt realize the rings were separate from Saturn, he  did describe them in his observing logs as handles, which piqued the interest of other astronomers. In 1655, Dutch astronomer Christiaan Huygens observed them and was the first to determine that these odd objects were actually rings of material circling the planet. Before that time, people were quite puzzled that a world could have such odd attachments.   Saturn, the Gas Giant The atmosphere of Saturn is made up of hydrogen (88 percent) and helium (11 percent) and traces of methane, ammonia, ammonia crystals. Trace amounts of ethane, acetylene, and phosphine are also present. Often confused with a star when viewed with the naked eye, Saturn can be clearly seen with a telescope or binoculars. Exploring Saturn Saturn has been explored on location by the Pioneer 11 and Voyager 1 and Voyager 2 spacecraft, as well as the Cassini Mission. The Cassini spacecraft also dropped a probe onto the surface of the largest moon, Titan. It returned images of a frozen world, encased in an icy water-ammonia mix. In addition, Cassini has found plumes of water ice blasting from Enceladus (another moon), with particles that end up in the planets E ring. Planetary scientists have considered other missions to Saturn and its moons, and more may well fly in the future.   Saturn Vital Statistics MEAN RADIUS: 58232 kmMASS: 95.2 (Earth1)DENSITY: 0.69 (g/cm^3)GRAVITY: 1.16 (Earth1)ORBIT PERIOD: 29.46 (Earth years)ROTATION PERIOD: 0.436 (Earth days)SEMIMAJOR AXIS OF ORBIT: 9.53 auECCENTRICITY OF ORBIT: 0.056 Satellites of Saturn Saturn has dozens of moons.

Training in Clinical and Counseling Psychology

Training in Clinical and Counseling Psychology Graduate school applicants who want a career in the field of psychology often assume that training in clinical or counseling psychology will prepare them for practice, which is a reasonable assumption, but not all doctoral programs offer similar training. There are several kinds of doctoral programs in clinical and counseling psychology, and each offers different training. Consider what you want to do with your degree counsel patients, work in academia or do research when you decide which program is best for you. Considerations in Selecting Graduate Programs   As you consider applying to clinical and counseling programs remember your own interests. What do you hope to do with your degree? Do you want to work with people and practice psychology? Do you want to teach and conduct research at a college or university? Do you want to conduct research in business and industry or for the government? Do you want to work in public policy, conducting and applying research to address social problems? Not all doctoral psychology programs will train you for all of these careers. There are three types of doctoral programs in clinical and counseling psychology and ​two different academic degrees. Scientist Model The scientist model emphasizes training students for research. Students earn a  Ph.D., a doctor of philosophy,  which is a research degree. Like other science Ph.Ds., clinical and counseling psychologists trained in scientist programs focus on conducting research. They learn how to ask and answer questions through conducting carefully designed research. Graduates of this model get jobs as researchers and college professors. Students in scientist programs are not trained in practice and, unless they seek additional training after graduation, they are not eligible to practice psychology as therapists. Scientist-Practitioner Model The scientist-practitioner model is also known as the Boulder Model, after the 1949 Boulder Conference on Graduate Education in Clinical Psychology in which it was first created. Scientist-practitioner programs train students in both science and practice. Students earn Ph.D.s and learn how to design and conduct research, but they also learn how to apply research findings and practice as psychologists. Graduates have careers in academia and practice. Some work as researchers and professors. Others work in practice settings, such as hospitals, mental health facilities, and private practice. Some do both. Practitioner-Scholar Model The practitioner-scholar model is also referred to as the Vail model, after the 1973 Vail Conference on Professional Training in Psychology, when it was first articulated. The practitioner-scholar model is a professional doctoral degree that trains students for clinical practice. Most students earn Psy.D. (doctor of psychology) degrees. Students learn how to understand and apply scholarly findings to practice. They are trained to be consumers of research. Graduates work in practice settings in hospitals, mental health facilities, and private practice.
