What is a parsec? One parsec is approximately 30 trillion kilometers or 19 trillion miles. That’s a bit over three light-years. The Voyager 1 probe, launched in 1977, is the most distant manmade object from Earth. It is a mere six ten-thousandths of a parsec away.

Parse Home : Technical Terms : Parse Definition. Parse. The word parse means to analyze an object specifically. It is commonly used in computer science to refer to reading program code. For example, after a program is written, whether it be in C++, Java, or any other language, the code needs to be parsed by the compiler in order to be compiled.

- A unit of distance equal to the distance from the sun to a point having a heliocentric (sun-centered) parallax of one second (second as an angle, not a time unit). 1 parsec = 3.26164 light years.

- Converting Parsecs to Light-Years and Miles. Each parsec equals 3.262 light-years; to find the distance to the star in light-years, multiply by 3.262. In the example, 4 parsecs times 3.262 equals 13.048 light-years. A parsec is equivalent to about 19 trillion miles, so 4 parsecs times 19 trillion is 76 trillion miles.arsec Calculation. The calculation to find parsecs is simple: take the angle measured between two star observations and divide it into 1. For example, you measure a difference of .25 seconds of arc between two observations of a star. To find the distance, 1 / .25 equals 4 parsecs.

Concasse Concasse, from the Frenchconcasser, to crush or grind, is a cooking term meaning to rough chop any ingredient, usually vegetables. This term is particularly applied to tomatoes, where tomato concasse is a tomato that has been peeled, seeded (seeds and skins removed), and chopped to specified dimensions. Specified dimensions can be rough chop, small dice, medium dice, or large dice.

- verb. to actively comprehend, to make sense of. To understand as a result of effort, as opposed to understanding intuitively. A derivative of the computer and linguistics term parse, to analyze data or a sentence for structure, content, and meaning. Most frequently used in parody of a hypothetical error message generated by a computer that was fed nonsensical data, eg, Does Not Parse.. She obviously had no idea what I was talking about.

Cusec Cusec is a measure of flow rate and is informal shorthand for cubic feet per second (28.317 litres per second). In the United States it is generally applied to water flow, particularly in rivers. Other informal synonyms are cfs and second-feet. 1 ft3s−1 = 0.028316847m3s−1, 1 ft3s−1 = 1 cusec.

Beta Volantis The parsec (symbol: pc) is a unit of length used to measure large distances to objects outside the Solar System. One parsec is the distance at which one astronomical unit subtends an angle of one arcsecond. A parsec is equal to about 3.26 light-years (31 trillion kilometres or 19 trillion miles) in length. The nearest star, Proxima Centauri, is about 1.3 parsecs (4.2 light-years) from the Sun.

- by John Carl Villanueva on September 10, 2009. 1 light year is the distance light can travel in vacuum in one year’s time. This distance is equivalent to roughly 9,461,000,000,000 km or 5,878,000,000,000 miles.This is such a large distance. For comparison, consider the circumference of the Earth when measured at the equator: 40,075 km.This visible-light image shows the galaxy dubbed UGC 3789, which is 160 million light-years from Earth.hat assignment is given to the parsec. 1 parsec is approximately equal to 3.26 light years. Another commonly used unit of distance is the astronomical unit or AU, wherein 1 AU is the average distance between the Earth and the Sun, and is roughly equivalent to 150,000,000 km.

Parsec A corollary is that a parsec is also the distance from which a disc one astronomical unit in diameter must be viewed for it to have an angular diameter of one arcsecond (by placing the observer at D and a diameter of the disc on ES).

What is a Parsec????? Knowing the distance to the sun, a quick bit of trigonometry gives you the distance to the star. If the angle between the lines from Earth is one arcsecond, the distance to the star is defined as one parsec which is around 30.9 trillion kilometres. It's easier than going there with a tape measure.

- Megaparsec. by Jean Tate on December 4, 2009. A megaparsec is a million parsecs (mega-is a prefix meaning million; think of megabyte, or megapixel), and as there are about 3.3 light-years to a parsec, a megaparsec is rather a long way. The standard abbreviation is Mpc.

Parsing Parsing. To parse a word means to analyze it into component morphemes. Recall that morphemes are the smallest units in a language that link a form with a meaning or function. Parsing is generally done on complex words that came from Latin and Greek.

Pars fracture The pars interarticularis is a part of the vertebra that is located between the articular processes of the facet joint, which connect adjacent vertebrae and stabilize the spine. A pars fracture is normally a stress fracture that develops as a result of overexertion, repetitive motions and frequent bending.

primase Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis. Since primase produces RNA molecules, the enzyme is a type of RNA polymerase.

Parsec A distance of 7003100000000000000♠1000 parsecs (7003326200000000000♠3262 light-years) is commonly denoted by the kiloparsec (kpc). Astronomers typically use kiloparsecs to express distances between parts of a galaxy, or within groups of galaxies. So, for example: 1  One parsec is approximately 3.26 light-years.

"Why in astronomy is distance measured in light ""years""?" The parsec is equal to 3.3 light-years. Using the light-year, we can say that 1  : The Crab supernova remnant is about 4,000 light-years away. 2  The Milky Way Galaxy is about 150,000 light-years across. 3  The Andromeda Galaxy is 2.3 million light-years away.

- We call this unique distance one parallax-second, or parsec. Finally, since one light year equals about 9.46 million million kilometers, and we said a parsec is 3.26 light years, simple multiplication tells us that one parsec is a distance of almost 31 million million kilometers. A long distance, to be sure!
