Galactic Center Region in Infrared from Spitzer

Galactic Center Region in Infrared from Spitzer
The Spitzer Space Telescope's infrared-light observations provide a detailed and spectacular view of the galactic center region. The swirling core of our galaxy harbors hundreds of thousands of stars that cannot be seen in visible light. These stars heat the nearby gas and dust. These dusty clouds glow in infrared light and reveal their often dramatic shapes. Some of these clouds harbor stellar nurseries that are forming new generations of stars. Like the downtown of a large city, the center of our galaxy is a crowded, active, and vibrant place.

About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    17h 45m 36.0s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    -28° 55' 58.8"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Sagittarius
  • 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.
    26,000 light-years (8 kiloparsecs)
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    The image of the galactic center is 32.5 arcminutes (246 light-years or 75.5 parsecs) wide.
