A new ‘Einstein ring’ is discovered

2 June 2016 Astronomy Now

This unusual phenomenon, predicted by Einstein’s theory of General Relativity, was discovered by chance by doctoral student Margherita Bettinelli at the Instituto de Astrofísica de Canarias while analysing images of the Sculptor dwarf galaxy. The “Canarias Einstein ring” is one of the most symmetrical discovered until now and is almost circular.


First light for future black hole probe

Zooming in on black holes is the main mission for the newly installed GRAVITY instrument at ESO’s Very Large Telescope in Chile. During its first observations, GRAVITY successfully combined starlight using all four 1.8-metre Auxiliary Telescopes. The first observations using GRAVITY with the four 8-metre VLT Unit Telescopes are planned for later in 2016.
