Galactic Portrait

Two enormous galaxies drift through the cosmic void in this striking image. The galaxy on the left is a lenticular galaxy named 2MASX J03193743+4137580. The side-on spiral galaxy on the right is more simply named UGC 2665. Both galaxies lie approximately 350 million light-years from Earth, and they both form part of the enormous Perseus galaxy cluster. The Perseus cluster is one of the biggest objects in the known universe, consisting of thousands of galaxies, only a few of which are visible in this image. The wonderful detail in the image is thanks to Hubble's Wide Field Camera 3's powerful resolution and high sensitivity. Wide Field Camera 3 is sensitive to both visible and infrared light, so those are the wavelengths that are captured in this image.
