About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.10h 47m 4.17s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.17° 16' 22.8"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Leo
- 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.98 million light-years (30 megaparsecs)
- DimensionsDimensionsThe physical size of the object or the apparent angle it subtends on the sky.This image is roughly 3.4 arcminutes (95,000 light-years or 29,000 parsecs) wide.

Pan of the galaxy NGC 3370 taken by Hubble's Advanced Camera for Surveys in early 2003. Adam Riess, an astronomer at the Space Telescope Science Institute in Baltimore, Md., observed NGC 3370 a dozen times over the course of a month and has seen many Cepheid variables. These...
Cepheid Variable in NGC 3370
Here we see a "movie" of 12 consecutive epochs of a long period (~50 days) Cepheid variable. The Cepheid is in the center of a crowded region of stars. The resolution of HST is required to pick out the variable star from its neighbors. The star was caught initially fading before...
