NGC 3344 (Leo Minor)

The galaxy features an outer ring swirling around an inner ring with a subtle bar structure in the center. A

bar is an elongated distribution of stars and gas in the center of a spiral galaxy. The central regions of

the galaxy are predominately populated by young stars, with the galactic fringes also featuring areas of

active star formation.

Central bars are found in around two thirds of spiral galaxies. NGC 3344’s is clearly visible here, although

it is not as dramatic as in some galaxies.

The high density of stars in galaxies’ central regions gives them enough gravitational influence to affect

the movement of other stars in their galaxy. However, NGC 3344’s outer stars are moving in an unusual

manner, although the presence of the bar cannot entirely account for this, leaving astronomers puzzled. It

is possible that in its past NGC 3344 passed close by another galaxy and acquired stars from it, but more

research is needed to state this with confidence.
