Compass and Scale Image for NGC 2976

About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    09h 47m 15.45s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    67° 54' 59.0"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Ursa Major
  • 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.
    This image is 2.8 arcminutes (9,800 light-years or 3,000 parsecs) wide.

Compass and Scale Image for NGC 2976
Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

The image is a composite of separate exposures made by the ACS/WFC instrument on the Hubble Space Telescope. Three filters were used to sample broad wavelength ranges in the near infrared. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F475W (B) Green: F606W (V) Red: F814W (I)

Compass and Scale
Compass and ScaleAn astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made.

Star-Birth Party Almost Over in NGC 2976

NGC 2976 does not look like a typical spiral galaxy, as this NASA Hubble Space Telescope image shows. In this view of the oddball galaxy's inner region, there are no obvious spiral arms. Dusty filaments running through the disk show no clear spiral structure. A raucous...
