Digitized Sky Survey Image of White Dwarf Stars in Hyades Cluster
The Hyades is the nearest open star cluster to our solar system, at 150 light-years from Earth. This image is a color composite of red- and blue-filter observations from the ground-based Digitized Sky Survey. The Hubble Space Telescope's Cosmic Origins Spectrograph was used to study the spectrum of two white dwarfs that are cluster members.
About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.04h 26m 52s.80
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.15° 52' 12.00"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Taurus
- DistanceDistanceThe 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.150 light-years (46 parsecs)
