Today's Picture: June 20, 1995 The Pleiades Star Cluster Picture Credit: Mount Wilson Observatory Explanation: The Pleiades star cluster, M45, is one of the brightest star clusters visible in the northern hemisphere. It consists of many bright, hot stars that were all formed at the same time within a large cloud of interstellar dust and gas. The blue haze that accompanies them is due to very fine dust which still remains and preferentially reflects the blue light from the stars.

Está compuesto por numerosas estrellas brillantes y calientes que se formaron todas al mismo tiempo en el interior de una gran nube de polvo y gas interestelar. La neblina azul que las acompaña se debe a polvo muy fino que aún permanece en la región y que refleja preferentemente la luz azul proveniente de las estrellas.
