Large astronomical instruments, such as the DECam, are housed on the Víctor M. Blanco telescope funded by the US Department of Energy. It was created for the Dark Energy Survey (DES), where more than 400 scientists from 25 institutions in seven countries mapped hundreds of millions of galaxies or galaxies. Detect thousands of supernovas and discover subtle patterns of cosmic structure. All of this to provide details about the mysterious dark energy that is the catalyst for the expansion of the universe.

Recently, the Victor M. Blanco telescope has released an image of the beamed spiral galaxies NGC 1512 (left) and tiny neighbors NGC 1510 (right). In addition to revealing the beautiful internal structure of NGC 1512, this image also shows NGC 1512’s outer lines stretching out that appear to envelop its tiny neighboring galaxies, with streams of bright stars seemingly connecting galaxies. both places together This is therefore evidence of gravitational interactions that have occurred for more than 400 million years. The gravitational action of NGC 1512 and NGC 1510 affects the rates of star formation in both galaxies. By twisting their shape, NGC 1512 and NGC 1510 will eventually merge to form a single large galaxy.

These galaxies are located in the direction of the constellation Horologium, about 40 million light-years from our planet.
