About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    11h 56m 28.13s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    55° 7' 30.86"
  • 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.
    68 million light-years (26 million parsecs)

Compass and Scale Image for NGC 3982
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 WFPC2, ACS, and WFC3 instruments on the Hubble Space Telescope. Three filters were used to sample broad and narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue/cyan: F555W (V) Red: F658N (H-alpha+[N II]) Red/yellow: 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.

Face-on Spiral Galaxy NGC 3982

Though the universe is chock full of spiral-shaped galaxies, no two look exactly the same. This face-on spiral galaxy, called NGC 3982, is striking for its rich tapestry of star birth, along with its winding arms. The arms are lined with pink star-forming regions of glowing...
