The telescope to observe this image had it origin in the early 20th century. The ideology to devise a space technology was done in 1923 by the German scientists Herman Oberth. He had the fundamental idea of observing events and assimilating data about the different aspects from space. In 1946 the American astrophysicist Lyman Spitzer Jr, furthered this original agenda of creating a telescope to monitor and assimilate data. He is considered to be the inspiration for creating a large telescope. In 1969 NASA basically created a big telescope that can monitor activities and collect data. The intricacies and the detailing of the telescope basically became complex with time and from the knowledge. In 1974 the large telescope basically had the technology to collect data that is one tenth of an arc second and can record the various wavelengths from UV rays to infrared rays. It could basically deduce the different wavelength across the spectrum and make significant calculations. IN 1975 the European agencies also got involved in this project and in 1977 The Hubble telescope name was devised and had officially started to function. This is the history behind this ambitious telescope project. The M100 that was found with the help of the HST is actually a cluster of stars, it has about 2500 galaxies in it and in this the spiral Messier 100 is seen to be the most prominent or what scientists call the most magnificent in them (Hubble Site, 2015b). Astronomers were able to observe that there were more than a dozen of these Cepheid variables and these Cepheid variables were capable of strong pulsations that occurred at a rate of weeks.
