Description

M74 - Subaru and HST

Here another composite image obtained by ground based observations recorded by the Subaru Telescope @ Mauna Kea and space data by the HST (for the galaxy core). The Subaru filters that have been assembled are Rc and B (G synthetic as (Rc+B / 2)) and HAlpha.
The HST data come from the ACS and WFPC2 detectors.

M74 is a "perfect spiral" galaxy placed some 32 milion light years from Earth towards the constellation of Pisces.
The galaxy contains two clearly defined spiral arms and is therefore used as an archetypal example of a grand design spiral galaxy. It is estimated to host approx. 100 billion stars.
