An image from the Dark Energy Camera Legacy Survey (DECaLS), a public survey mapping 6700 square degrees, approximately one-sixth of the sky, using the Blanco 4-m telescope at the Cerro Tololo Inter-American Observatory. The image shows the interacting galaxy system UGC 12589 at a distance of 470 million light-years. The distorted morphologies and diffuse light result from the gravitational interaction between the galaxies.
Digital tracking dramatically increases the sensitivity of a telescope to faint asteroids. A recent study illustrates the potential of this approach using data from the 0.9m WIYN telescope on Kitt Peak.
Eight new dwarf galaxy “neighbors” of the Milky Way discovered in recent data from the Dark Energy Survey. The survey is being carried out on the 4-m Blanco telescope at CTIO.
