How far is a star or a galaxy? Scaling and measuring the cosmos is a complex problem. Scientists are integrating mathematical applications and scientific technology to create standards. Distances are so vast they are described in light years - the distance light travels in a year. Nearby stars are measured by trigonometry - the technique of parallax. Farther out, astronomers use so-called "standard candles", the 'Type Ia supernovae' is the standard candle basis. Beyond that the electromagnetic "redshift" of galaxies reveals their distances.
