The NASA Hubble Space Telescope's Wide Field and Planetary Camera 2 snapped this wide view of the nearby barred spiral galaxy NGC 1512. A wispy bar of material can barely be seen slicing vertically through the galaxy. The bar is funneling gas to the heart of the galaxy, fueling a ring of star birth. Blue-colored stars along the galaxy's outer edge trace the grand spiral arms.

| About The Object | |
|---|---|
| Object Name | A name or catalog number that astronomers use to identify an astronomical object. |
| Object Description | The type of astronomical object. |
| R.A. Position | Right ascension – analogous to longitude – is one component of an object's position. |
| Dec. Position | Declination – analogous to latitude – is one component of an object's position. |
| Constellation | One of 88 recognized regions of the celestial sphere in which the object appears. |
| Distance | The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs. |
| Dimensions | The physical size of the object or the apparent angle it subtends on the sky. |
