Astronomy Coursework Help

Future years will see an armada of new large telescopes brought to bear on some of the most important astronomical questions being asked today. Astronomers also study data gathered by physicists using particle accelerators.Key questions about the big bang and the nature of matter in the universe can only be answered by studying the behavior and forces of elementary particles and, perhaps, discovering new particles.Robert O'Dell of Rice University aimed NASA's Hubble Space Telescope at the rich star-forming region known as the Orion Nebula to study newborn stars.

Such discoveries not only reveal a universe richer and more varied than had been suspected by previous generations, but pose bold, new challenges for scientists. Interplanetary spacecraft have observed eight of the nine planets in phenomenal detail, mapped and landed on the surfaces of the moon, Mars, and Venus, and returned the first close-up images of a comet nucleus and several asteroids.

Orbiting observatories scrutinize star clusters, nebulae, the violent cores of galaxies, and distant quasars.

Many entering students have taken advanced placement calculus and/or physics, though these courses are not required.

Students are also encouraged to get involved in high school science groups, state junior academies of science, and local amateur astronomy clubs.

Rather, astronomers must apply equal measures of analytic thinking and imagination, logic and intuition, to answer the most fundamental questions about the cosmos: What are stars and planets? Although most colleges require at least one year of high school science and two years of high school mathematics, this minimum background is insufficient for students planning to major in science.

A better approach is to complete math through pre-calculus in high school.It is this challenge and the satisfaction gained by solving these puzzles that drew me to astronomy." — Tereasa Brainerd, California Institute of Technology.Primary research of interest: the origin and evolution of structure in the universe."I was struck by the unique appearance of a train of individual [comet] nuclei all lined up in a row," Said Dr. "I had never before seen such a unique image in a comet." In fact, nothing like it had been seen by other astronomers either.The pearls were the remnant of a comet that had come too close to Jupiter and broke into at least 21 fragments.Lava is one possibility, but to carve the narrow channel, it would have had to flow rapidly and with the consistency of paint."The very existence of such a channel is a great puzzle," said Dr.Even more extraordinary, 18 months later these comet fragments, known collectively as Comet Shoemaker-Levy 9, would collide with Jupiter, providing astronomers the opportunity to study such an event for the first time!The Magellan spacecraft had already mapped over 84 percent of the surface of Venus with its imaging radar when it revealed a surprising new feature: a narrow channel snaking its way 4,200 miles across the hellish surface.This gives students who plan to major in astronomy or physics the necessary grounding in mathematics needed to start their science courses as soon as they begin college.Both chemistry and physics courses are also strongly recommended in high school as adequate preparation for the first year of college.
