| About the Object |
| Object Name: |
High Redshift Galaxy (named IR 1916) in Abell 1835 |
| Object Description: |
Galaxy Cluster, Gravitational Lens |
| Position
(J2000): |
R.A. 14h 01m 02.0s
Dec. +02°51'32"
|
| Constellation: |
Virgo |
| Distance to Lensed
Galaxy: |
Approximately 13.23 billion light-years (4.06 billion parsecs) |
| Distance to Abell 1835: |
Approximately 3billion light-years (920 million parsecs)
|
| Dimensions: |
This large image covers a field of appox.1 by 2 arcminutes
side. At this distance to Abell 1835, this is roughly 780'000
by 1'560'000 light-years across (240'000 by 480'000 parsecs).
The small images are approx. 8 by 12 arcseconds wide, which
corresponds to 100'000 by 150'000 light-years accross (32'000
by 48'000 parsecs).
The visible part of the distant "proto-galaxy"
IR 1916 (shown in the white circle) is less than 1000 parsecs
across, i.e. smaller than ~ 3000 light years! In comparison
our Galaxy, the Milky Way, is at least ten times larger.
