The last few days have seen the ATNF telescopes combining with
those of partner institutions to undertake observations using
the technique of Very Long Baseline Interferometry (VLBI).
The Parkes 64m telescope has an angular resolution
measured in arcminutes (comparable to the human eye),
the 6km baselines of the ATCA yield angular resolutions
measured in arcseconds, and VLBI arrays with baselines of
thousands of kilometers have angular resolutions of
milli-arcseconds, which corresponds to linear resolutions
of some astronomical units (Earth-Sun distances) within
our Galaxy, or light-year scales in other galaxies.
The ATNF telescopes work together with those from
the UNiversity of Tasmania, the Hartebeesthoek Radio
Astronomy Observatory in South Africa, and the Auckland
University of Technology. (Collage credit: Emil Lenc)
