M45, commonly known as the Pleiades or the Seven Sisters, presents a captivating celestial panorama with distinctive blue hues in astrophotographs. The dominant reason behind this intense blue appearance lies in the interstellar dust surrounding the stars within the cluster. As starlight passes through this cosmic dust, it undergoes a process known as Rayleigh scattering.

Rayleigh scattering, more commonly associated with why the Earth's sky appears blue during the day, occurs when short wavelengths of light (such as blue) scatter more effectively than longer wavelengths (such as red). In the case of the Pleiades, the blue light from the stars is scattered by the intervening interstellar dust, resulting in the cluster's pronounced blue coloration when captured through astrophotography.

This scattering phenomenon not only contributes to the distinct visual beauty of the Pleiades but also serves as a valuable astrophysical tool for astronomers. By studying the extent of this scattering, scientists can gain insights into the distribution and properties of the intervening interstellar material, providing a deeper understanding of the cosmic environment surrounding this iconic star cluster.
