NGC 4625

NGC 4625 is a distorted dwarf galaxy in the constellation Canes Venatici.

[3] It has been hypothesized that this galaxy's asymmetric structure may be the result of a gravitational interaction with NGC 4618.

Ultraviolet observations of NGC 4625 made by the Galaxy Evolution Explorer (GALEX) show the presence of an extended disk.

The new spiral disk extrends 28,000 light-years from the galaxy center, a staggering four times the optical radius.

[5] The UV-to-optical colors suggest that the bulk of the stars in the disk of NGC 4625 are currently being formed, providing a unique opportunity to study today the physics of star formation under conditions similar to those when the normal disks of spiral galaxies like the Milky Way first formed.

An ultraviolet image of NGC 4625 taken with GALEX shows a disc four times larger than what is seen in visible light
