NGC 4452: An Extremely Thin Galaxy

While to most people this picture would look simply like a bright line in the sky, astronomers are able to identify it as a galaxy being seen perfectly edge on.  This galaxy, known as NGC 4452, belongs to Virgo Cluster of Galaxies.  Because it is a disk galaxy, it makes it hard to determine what type of galaxy it actually is.  It is likely a low-dust lenticular galaxy because of its lack of a visible dust lane.  NGC 4452 has an estimated span of 35,000 light years.  Our own Milky Way is thought to be just as thin as this galaxy!!
