A parallax error is the perceived shift in an object's position as it is viewed from different angles. The error is most easily noticed by looking at a nearby object with one eye closed, then looking at it through the other eye. The apparent motion of the object is the parallax shift, and it is resp


In chemistry, a parallax error is a deceptive shift in an object's actual position due to personal perception. This type of error commonly occurs in a laboratory setting with the use of specialized measuring instruments called volumetric glassware.


Spectroscopic parallax is a technique that is used in the field of astronomy to estimate how far a star is from a certain point like the surface of the earth. Cliffsnotes.com explains that the method involves comparing the star’s absolute size with its apparent size which is obtained by measuring.


Simplifying trigonometric expressions is a matter of understanding the circles and triangles upon which trigonometry is based. While much of the simplification can be done geometrically, knowledge of trigonometric identities will allow an algebraic solution.


Astronomy is a field of science that studies the nature and motions of celestial bodies. This includes studying objects such as stars, planets and entire galaxies.


Astronomy, and space science generally, is an effective method for broadening the human perspective, contributing new ideas and technologies and alerting the world to impending harm. After the unexpected Russian 2013 meteorite strike, astronomers at the University of Hawaii announced plans to build


Though the parallax method for working out distances has been known since Euclid, even the closest stars are so distant that their shift could not be measured with the necessary precision until the 19th century. The largest stellar parallax, that of Alpha Centauri, is approximately 77 arcseconds. Th


Some good sources for astronomy news include ScienceDaily and Space.com. As of 2015, both of these websites offer recent articles concerning space and astronomy to read for free.


The pursuit and study of astronomy as a science can be difficult at times, but the degree of difficulty is subjective to different individuals. Advancing through astronomical studies leads to questions and problems of greater difficulty.


Good ways to learn the latest astronomy news are to read astronomy periodicals, visit websites devoted to astronomy, and read updates from space-related organizations. Magazines such as Sky and Telescope and Astronomy Magazine are published monthly and are devoted exclusively to astronomy news, whil
