HST Snaps Optical Jet of Quasar 3c 273

 HST Snaps Optical Jet of Quasar 3c 273

The Green (V band) image (left) shows the field around the quasar 3c 273 (courtesy Matthew Colless, David Schade and the CFHT). The optical jet can be seen SW of the quasar. The blue (B band) image (right) shows the optical jet as seen by the Faint Object Camera (FOC) on board the Hubble Space Telescope. For comparasion, the 11X11 arcesec FOC field of view is marked on the ground based CFHT image. The insert (right) is a Maximum Entropy reconstructionof the FOC image. This FOC image is derived from three linearly polarized images which show that the brightest knots are highly polarized (20%-50%). a letter which describes these data appears in the 9 September 1993 issue of Nature.

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.
