By analyzing the data from the Dark Energy Survey (DES), an international team of astronomers has conducted a search for nearby faint dwarf galaxies. In result, they detected three such objects around the Sculptor Galaxy. ...
One of the largest X-ray surveys using the European Space Agency's XMM-Newton space observatory has mapped nearly 12,000 X-ray sources across three large, prime regions of the sky. The X-ray sources represent active galactic ...
