Barred Spiral Galaxy COSMOS 1161898

Barred Spiral Galaxy COSMOS 1161898
Barred spiral galaxy COSMOS 1161898 is located 5.3 billion light-years away from Earth. The galaxy is part of a landmark study of more than 2,000 spiral galaxies from the largest galaxy census conducted by the Advanced Camera for Surveys aboard NASA's Hubble Space Telescope. The observations are part of the Cosmic Evolution Survey (COSMOS). Astronomers assembled this image from observations taken between fall 2003 and spring 2005 with Hubble and the Subaru Telescope in Mauna Kea, Hawaii.

About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    10h 0m 0.0s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    02° 12' 0.0"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Sextans
  • 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.
    5.3 billion light-years, Redshift: z=0.54
