This image shows the HCG 98 group. The core of HCG 98 consists of the two ‘smudges’ at the center of the image. Each is a galaxy much like our own Milky Way Galaxy. The tadpole structure covers the central galaxy pair and was formed when the pair demolished a much smaller galaxy. Image credit: Brosch et al, doi: 10.1093/mnras/sty2717.

This Hubble image shows a supernova remnant called SNR 0454-67.2. The color image was made from separate exposures taken in the visible region of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). 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.

Images of four colliding galaxies, along with close-up views of their coalescing nuclei in the bright cores, are shown beneath the Hubble snapshots of NGC 6240. The left image of each pair, showing the merging galaxies, was taken by the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS). The right image, showing the bright cores, was taken in near-infrared light by the W. M. Keck Observatory in Hawaii, using adaptive optics to sharpen the view. The nuclei in each of the Hubble and Keck Observatory infrared photos are only about 3,000 light-years apart -- a near-embrace in cosmic terms. If there are pairs of black holes, they will likely merge within the next 10 million years to form a more massive black hole. These observations are part of the largest-ever survey of the cores of nearby galaxies using high-resolution images in near-infrared light taken by the Hubble and Keck observatories.
