Wide view of Barred Spiral Galaxy NGC 1512

Wide view of Barred Spiral Galaxy NGC 1512
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

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    04h 3m 54.29s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    -43° 20' 56.0"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Horologium
  • Distance
    DistanceThe 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.
    9.2 million pc (30 million light-years)
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    The galaxy is 70,000 light-years across. The circumnuclear starburst ring is 2,400 light-years wide.
