Noise variations in the two regions covered by the second data release from the LOw-Frequency ARray (LOFAR) Two-metre Sky Survey with the coverage of the 841 individual pointing outlined. The RA-13 (top) and RA-1 (bottom) regions span 4,178 and 1,457 square degrees and have median rms values of 74 μJy beam−1 and 106 μJy beam−1 respectively. Failed facets (white regions) are generally caused by either poor ionospheric conditions or dynamic range issues around bright sources such as 3C 48 and 3C 196.

This Hubble image shows the galaxy pair NGC 4496. The color image is composed of infrared, optical and ultraviolet observations from Hubble’s Wide Field Camera 3 (WFC3), the Dark Energy Camera (DECam) on the Victor M. Blanco 4-m Telescope, and the Sloan Digital Sky Survey (SDSS). Nine 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 / T. Boeker / B.
