This Hubble image shows the galaxy cluster MACS J0138.0-2155, which is so massive that its gravity bent and magnified light streaming not only from an extremely distant background galaxy but also from a supernova event in this galaxy. The color image was made using observations from eight different filters spread across Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / A. Newman / M. Akhshik / K. Whitaker.

A special feature in the feeding behavior of the giant panda (Ailuropoda melanoleuca), related to eating bamboo, is the habit to skim the outer green skin of the hard bamboo culm; although the feeding preferences have a seasonal shift, the culm is consumed and skinned during all the year; while eating culm, the outer skin is removed for reasons which until now have remained poorly understood.
