While my project will involve looking mainly at X-Ray data, in astronomy it is always important to keep the big picture in mind. Every different category of light is important and gives us individual information which should be considered. This is a summary of the different wavelengths of light astronomers use and the objcts they are particularly useful for.
(I first blogged this for the National Space Centre here)
Humans have been looking out into space for thousands of years and finding lots of weird and wonderful objects among the stars. Using only our eyes and various strengths of telescopes we can spot thousands of these astronomical features, but this is only a fraction of the fascinating and exotic phenomena out there.
The Electromagnetic Spectrum
The light our eyes recognise is a small selection of the whole electromagnetic spectrum; there are many different wavelengths of light and all of them tell us something about the objects they come from. To discover all we possibly can about astronomical phenomena, light of all these different wavelengths is gathered and analysed by specially designed telescopes. Continue reading
