Astronomers have spotted Einstein’s ring in distant galaxy with the most powerful ground based observatory in the world. Atacama Large Millimeter/submillimeter Array (ALMA) telescope which is located in Chile’s Atacama Desert is the most powerful telescope.
The telescopes antenna is 15 Kilometers apart to detect distant objects.
At the end of 2014 during the ALMA’s Long Baseline Campaign the telescope has observed ancient galaxy called SDP.81. This galaxy is warped by massive foreground galaxy and bent around warped spacetime.
According to scientist this galaxy began forming when the Universe was just 15 percent of its age today.
The warping seen is galaxy was first observed by Hubble telescope.
Warping is produced when source of light become warped around massive objects in the galaxy clusters. Bright arcs appear very often but they transform into circle creating Einstein’s rings.
Frontier Fields a project by Hubble captured arcs from distant galaxies but it couldn’t capture complete ring and these pieces of information were used to study the stellar formations but ALMA high resolution image detailed the young galaxy’s feature.
Dr Jacqueline Hodge of the National Radio Astronomy Observatory, a co-author of the study said, “The exquisite amount of information contained in the ALMA images is incredibly important for our understanding of galaxies in the early Universe.”
