  What it is

Dwarf galaxy NGC 4214 may be small, but what it lacks in size it makes up for in content. It is packed with hot young star-forming regions and old clusters with red supergiants. A huge heart-shaped cavity — possibly the galaxy’s most eye-catching feature — can be seen at the center of the image. Inside this hole lies a large cluster of massive young stars ranging in temperature from 10,000° to 50,000° Celsius. Their strong stellar winds are responsible for the creation of this hollow area. The resulting lack of gas prevents any further star formation from occurring in this region.
