When is parallax used for?
A parallax is a change in apparent position, when YOU move. In astronomy, it usually refers to the change in the apparent position of a star, due to Earth's orbit around the Sun. It's there, whether you "use" it or not, but it is quite useful to determine distances of stars that are relatively close to us - since the farther a star is, the smaller will the parallax be. Even for the nearest star after the Sun, the parallax is smaller than one second (1/3600 of a degree).
Which movies have the word distance in the title?
"The Loneliness of the Long Distance Runner" (1962). Stars Michael Redgrave. "Striking Distance" (1993). Stars Bruce Willis, Sarah Jessica Parker, Dennis Farina. "Going the Distance" (2010). Stars Drew Barrymore.
What did the astronomers of Babylon map?
the astromers of babylon mapped the stars and the plants
Define light year and explain its value in astronomy?
A light-year is the distance light travels in a year - equivalent to almos 10 million million (or 1013) kilometers. In popular astronomy, distances to stars or galaxies are often stated in light-years; although astronomers often prefer another measure, the parsec, equivalent to about 3.26 light-years.A light-year is the distance light travels in a year - equivalent to almos 10 million million (or 1013) kilometers.

Do distant galaxies have more heavy elements than nearby galaxies?
The distribution of metals (In astronomy, that is any element other that hydrogen and helium) is reliant of the population stars. (See related question) Metal rich stars, population I stars, are the latest "breed" of stars, whereas population III stars are the oldest and are classed as metal free stars. So the furthest galaxies are likely to be formed from the initial gases from the big bang and will be metal free stars,
What is used to determine the distance to nearby stars?
They use trigonometry to determine the distance to nearby stars. They measure the star's positions at one point in time, and again six months later, calibrating against the backdrop of the far distant stars. The nearby stars will show a parallax shift in position, so they calculate a triangle, with the Earth at two points, and the base 186 million miles long. The star is the third point on the triangle, and it is simple trigonometry from there to figure out the distance.
What method do astronomers use to determine the distance to a relatively close star like Sirius?
For nearby stars, the parallax method is used.
The distance to nearby stars can be measured by using?
Parallax
Distance to nearby stars can be determined from?
stellar parallax
How do astronomers measure the distance to nearby stars?
Astronomers use a method called parallax to measure the distance to nearby stars. Astronomers can measure parallax by measuring the position of a nearby star with respect to the distant stars behind it. Then, they measure the same stars again six months later when the Earth is on the opposite side of its orbit.
Method to measure the distance to nearby stars directly?
For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.
What ways can you measure th distance to nearby stars?
You can measure it by using absolute magnitude.
Why do we measure the movement of stars?
Parallax is the apparent change in position of an object when you look at it from different angles. Astronomers often us parallax to measure distances to nearby stars. This method can be used to determine stars' distances up to 400 light-years from Earth.
What is one way scientist use to calculate the age of the universe?
Measure the distance from Earth to nearby stars.
Can the distances to nearby stars be measured by color?
That is one of the things scientists use to help them measure a stars distance but it isn't just based on the color.
What is sentence of always?
Passive voice: It has always been hard to determine distance to the stars. Present voice. As always, it is difficult to determine the distance to the stars. Future participle: According to Einstein, it will always be difficult to determine if relativity is correct. Object; What is a sentence of always?
Could parallax be used to determine the distance of all stars?
