Messier 45 January 2025
Messier 45, The Pleiades or The Seven Sisters, is an open star cluster containing young, hot B-type stars situated in the constellation of Taurus. It lies at a distance of around 444 light-years and is one of the nearest star clusters to us. The cluster is dominated by hot blue luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be leftover material from their formation but are now considered likely to be an unrelated dust cloud in the interstellar medium through which the stars are currently passing.
Imaged over 2 nights, the 2nd and 7th January 2025.
