Your research and astrophotography are especially interesting. I absolutely enjoy reading your insights and seeing your photos. I’d love to write something of important and encouraging value here but all I can add is that I read in a book recently, “most atoms in each of our bodies were built up out of smaller particles produced in the furnaces of long-gone stars.” Which is amazing considering you take pictures of galaxies so far away.
Thank you! Glad that I could give you some enjoyment with my articles and astrophotography! Also, that is one of my favorite facts – we are all made up of star dust.
