From now I want to teach you some simple collocation of astronomy and then I will bring you a fantastic picture with some explanations

So the first collocation

Reflection Nebula

A reflection nebula is created when light from a star is scattered or reflected off a neighbouring dust cloud. The scattered light is slightly polarised and has a spectrum similar to that of the illuminating star, only bluer. This shift in colour arises because the typical size of dust grains in the cloud are comparable to the wavelength of blue light. The result is that blue light is scattered more efficiently than longer, red wavelengths giving the characteristic blue colour for these nebulae

Reflection nebulae are usually less dense than dark nebulae, and have sizes that are determined by the source of illumination. Their extent is not defined by the size of the dust cloud but rather the area over which their brightness remains above the point of detection.
The nebulosity surrounding the stars in the Pleiades is perhaps the most well known example of a reflection nebula

Alfred Nobel (1833-1896) was born in Stockholm, Sweden, on October 21, 1833. His family was descended from Olof Rudbeck, the best-known technical genius in Sweden in the 17th century, an era in which Sweden was a great power in northern Europe. Alfred's mother, born Andriette Ahlsell, came from a wealthy family. His father Immanuel Nobel was an engineer and inventor who built bridges and buildings in Stockholm. In connection with his construction work Immanuel Nobel also experimented with different techniques for blasting rocks. Immanuel Nobel was also a pioneer in arms manufacture and in designing steam engines. Due to misfortunes in his construction work caused by the loss of some barges of building material, Immanuel Nobel was forced into bankruptcy the same year Alfred Nobel was born. Nobel was fluent in several languages, and wrote poetry and drama. Nobel was also very interested in social and peace-related issues, and held views that were considered radical during his time. In St. Petersburg, Immanuel's sons were given a first class education by private teachers. The training included natural sciences, languages and literature. By the age of 17 Alfred Nobel was fluent in Swedish, Russian, French, English and German. His primary interests were in English literature and poetry as well as in chemistry and physics. Alfred's father, who wanted his sons to join his enterprise as engineers, disliked Alfred's interest in poetry and found his son rather introverted
