Radio telescope at Arecibo only localized the fast radio burst to the area inside the two circles in this image, but the Very Large Array was able to pinpoint it as a dwarf galaxy within the square (shown at intersection of cross hairs in enlarged box)
While the radio telescope at Arecibo Observatory could only localize the fast radio burst to the area inside the two circles in this image, the Very Large Array pinpointed it as a dwarf galaxy within the square, shown at the intersection of the cross hairs in enlarged box. [Image 2 of 3 related ...
