Abstract
The author Douglas Adams once described the Earth as an “insignificant little blue-green planet” orbiting a “small unregarded yellow sun”. 1 Adams D The hitchhiker's guide to the galaxy. Pan Macmillan, London, UK1979 Google Scholar Our star is not essentially spectacular, but it is also not particularly unique. There are many spiral galaxies similar to the Milky Way, all with a range of different star types, including many similar to our own. The creation of such stars can be seen by looking further and further out at star-forming regions (nebulae). One spectacular star-forming region is the Orion nebula. Easily visible to the naked eye as a fuzzy spot in the Orion constellation, the nebula is roughly 1500 light years from us, and the closest stellar nursery. Near impenetrable at visible wavelengths due to the clouds of gas and dust from which the young stars are forming, the nebula's energetic heart can be viewed easily at X-ray wavelengths.
