This week’s image is from the Hubble Space Telescope. It shows spiral galaxy NGC 3137 in all its glory. We are getting a nice inclined view of the galaxy, allowing us to see multiple arms of stars.
The European Space Agency (ESA) describes what we are seeing in this way:
A spiral galaxy seen close up and tilted at an angle, so that its disc fills the view from corner to corner. Its disc is yellow near to the centre and pale blue farther out, showing cooler and hotter stars, respectively. Thin brown clouds of dust, glowing pink spots of star formation, and sparkling blue patches filled with star clusters swirl through the galaxy. Behind it, small orange dots are very distant galaxies.
