The discovery of Tyrannosaurus mcraeensis, a sister species of the famous Tyrannosaurus rex, suggests that tyrannosaurid dinosaurs originated on Laramidia, an island continent that existed between 100 and 66 million years ago and stretched from modern-day Alaska to Mexico.

Two spiral galaxies, NGC 6040 and NGC 6039, are merging together at the right side of this Hubble image. NGC 6039 is seen face-on and is circular in shape. NGC 6040 seems to lie in front of the first one. In the lower-left corner, cut off by the frame, the elliptical galaxy NGC 6041 -- a central member of the galaxy cluster that Arp 122 resides in -- appears as light radiating from a point. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) and the Dark Energy Camera, which is mounted on NSF’s Víctor M. Blanco 4-m telescope at Cerro Tololo Inter-American Observatory in Chile. Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / J.
