... 2003 December 15 . Open Star Clusters M35 and NGC 2158 . ... NGC 2158 is four times more distant that M35 , over 10 times older, and much more compact as it contains many more stars in roughly the same volume of space. NGC 2158 's bright blue stars have self-destructed , leaving cluster light to be dominated by older and yellower star s. Both clusters are visible toward the constellation of Gemini -- M35 with binoculars and NGC 2158 with a small telescope. ... About APOD | ...

Some additional inquiry information . ... WPGMA . As any cluster method , UPGMA (unweighted pair-group method of analysis) performs the structure of a set of some homogeneous elements ( in our case alignment is a set of amino acid sequences ). ... Firstly, when we calculate correlations between distance matrices on the whole alignment and on separate position (for selecting "diagnostic" positions) - we should be sure that these data are not distorted by multiple repeating of one sequence. ...

PETROTYP has been designed for clustering igneous rock compositions given as concentrations of major element oxides. This program is based on principles of hierarchical grouping of objects that are characterized by an array of parameters described as an objective function (Ward, 1963). The major principle involves a subsequent combining of samples having the minimum geochemical distance (GD) with respect to other rocks or average cluster compositions formed at a previous stage. ...
