About The Data
Data Description Note: The wide-field image of M81 was released on May 28, 2007. ACS/WFC data from proposal (PI: A. Zezas (Harvard-Smithsonian Center for Astrophysics)) was combined into a BVI color-composite image. Hubble data for this release of SN 1993J were obtained from proposal : A. Filippenko (University of California, Berkeley), P. Chandra (Pune University, India), R. Chevalier (University of Virginia), V. Dwarkadas (University of Chicago), C. Fransson (Stockholm University), W. Li (University of California, Berkeley) T. Matheson (NOAO), J. Silverman (University of Texas, Austin), N. Smith (Steward Observatory), and S. Van Dyk (Caltech). The science team comprises: O. Fox (University of California, Berkeley), A. Bostroem (STScI), S. Van Dyk (Caltech), A. Filippenko (University of California, Berkeley), C. Fransson (Stockholm University), T. Matheson (NOAO), S. Cenko (University of California, Berkeley, and NASA/GSFC), P. Chandra (Pune University, India), V. Dwarkadas (University of Chicago), W.

About The Object
Object Name A name or catalog number that astronomers use to identify an astronomical object.
Object Description The type of astronomical object.
R.A. Position Right ascension – analogous to longitude – is one component of an object's position.
Dec. Position Declination – analogous to latitude – is one component of an object's position.
Constellation One of 88 recognized regions of the celestial sphere in which the object appears.
Distance The 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.
Dimensions The physical size of the object or the apparent angle it subtends on the sky.
