Mrk 3 HST
Here is another active galactic nucleus captured by Hubble—this time in a lenticular galaxy rather than a barred spiral. Interestingly, there are a few dusty tendrils visible against the northern half of the galaxy that are off-axis compared with the active galactic nucleus (AGN) torus and disk of the galaxy. Visible in a blueish hue, beams of light shine brightly from the poles of the AGN, appearing to us as two cones of light. They are illuminating and ionizing gaseous structures that would otherwise be invisible to us at these wavelengths.
A version featuring Chandra x-ray data is here.
Data from the following proposals were used to create this image:
