Previously, the Cepheid variables of other galaxies could not be used for distance measurement because they cover metallicity ranges that differ from those of the Milky Way. Refrain from using words such as a, and, for, the, etc. Using the Spitzer data, the researchers estimated that stars are forming in the central regions of NGC … Read more
