Six-Image CLASS Gravitational Lens

Description

This object was discovered during the third phase of the Cosmic Lens All-Sky Survey (CLASS), an international collaboration that searches for new cases of gravitational lensing among compact radio sources. This is a composite image showing the Hubble Space Telescope image of the gravitational lens system B1359+154, and six VLBA images of the lensed background radio source. The white objects are the multiple lensed images of the background galaxy, more than 11 billion light-years away. The orange objects are images of the three galaxies some 7 billion light-years away whose gravity is bending the light from the background galaxy to produce the multiple images. This is the first arcsecond-scale system in which a source is lensed into more than four detectable images.
VLBA images (15 x 15 milliarcsecond boxes) made from a 10-hour observation at 1.7 GHZ. HST image (2.9 x 2.9 arcsec) made from a 5000 second observation in the I band.
