An international group of astronomers reports the detection of a new dwarf galaxy in the so-called Magellanic Bridge – a stream of gas linking the two Magellanic Clouds. The newly found galaxy, designated Hydrus 1, is described ...
EPFL scientists have completed the fastidious task of analyzing 27 dwarf galaxies in detail, identifying the conditions under which they were formed and how they've since evolved. These small-scale galaxies are perfect for ...
