Because of this, measuring the sizes of galaxies can often be difficult and have a wide range of results depending on the sensitivity of the detection equipment and the methodology being used. (The lobes are megaparsecs away from each other, which means they are far enough apart to feel substantial Hubble expansion!) This is the diameter measured through the quoted estimation method. The galaxy, called Alcyoneus, is about 3 billion light-years from Earth and about 16.3 million light-years long. Max can be found two nights a week probing the mysteries of the Universe at the Kitt Peak National Observatory. By comparing the data with the formation of the largest galaxy ever discovered, scientists are expecting to gain more insights into the formation of galaxies. After its initial discovery, the researchers have continued to process data surrounding Alcyoneus. The dwarf galaxy known as Segue 2 is bound together by a tiny clump of dark matter. The Comet Galaxy is the fifth largest known galaxy and the first on the list that is not an elliptical galaxy. This feature is the largest known in the Universe to correspond to a single galaxy, and makes Alcyoneus the largest known galaxy in the Universe at present. The physical diameters given by NED for this object are based on the mean of one or more redshift-independent distance techniques, which are subject to errors and sensitivity to extreme values. That makes Alcyoneus roughly 153.77 times longer than the Milky Way. 2022 BGR Media, LLC. Biggest Galaxy.
