How do we know the composition of distant stars?

What stars are made of is determined through the help of spectroscopy.

This involves the study of a star’s spectrum which is created by the electromagnetic radiation that it emits. Spectroscopy can not only derive the chemical composition of distant stars and galaxies, but can also determine their temperature, density, mass, luminosity and relative motion.

Stars emit at all wavelengths across the electromagnetic spectrum, along with many discrete absorption lines at certain wavelengths. These lines, which appear black on a colourful emission spectrum, result from a deficiency of observed photons at those particular wavelengths since its light is absorbed. It

The first step is an array of field sobriety tests, which includes sniffing your breath. If your performance is at par with a baby learning- to walk, either through intoxication or a God-given lack of motor skills, then you will go through a breath analyzer exam to determine the alcohol content of your blood. However, the legal limit is not yet set. The Department of Transport and Communications, Department of Health, and National Police Commission are still banging their heads together to figure it out (which is anytime in the next three months).

How can I fake a zoom burst?

I love trying out your tutorials and would really like to have a go at creating the zoom burst effect that I have seen in the magazine. There are lots of flowers in my garden that I think would look great when shot with this technique. I know that you need to zoom out while taking the shot, but unfortunately I only have a compact camera that won’t let me do this.
