Most galaxies fall into two main categories: spiral galaxies and elliptical galaxies (which have a regular stellar population of older and redder stars).
The galaxy in this #HubbleFriday image requires more detailed study to determine its type. Although it has a smooth disk with no arms like an elliptical galaxy, it has active star formation and a population of relatively young stars.
Its unique shape and star-forming activity puts it in the category of a lenticular galaxy, the result of a cosmic collision with a nearby dwarf galaxy. Lenticular galaxies don't have spiral arms, but they do contain enough gas to form more stars than elliptical galaxies.
NGC 4694 is located in the Virgo galaxy cluster, about 54 million light-years away.
Image description:
An oval-shaped galaxy is seen tilted at an angle. It glows brightly at its core and fades towards the edge of the oval, spreading outwards. Reddish-brown, patchy dust radiates from the core and covers most of the galaxy's upper half and outer edge, obscuring some of its light. Stars can be seen around and in front of the galaxy.
