Barnard’s Star is a familiar name in both the history of astronomy and popular culture, but did you realise that it’s the closest stellar body to the Sun that you can see from the British Isles and similar latitudes? We tell you some fascinating facts about this famous runaway star and show you how to locate it.
The creation of a specialised IAU Working Group, the Working Group on Star Names (WGSN), was approved by the IAU Executive Committee in May 2016 to formalise star names that have been used colloquially for centuries. WGSN has now established a new catalogue of IAU star names, with the first set of 227 approved names published on the IAU website.
The NASA/ESA Hubble Space Telescope has given us this stunning view of the closest bright stars Alpha Centauri A (on the left) and Alpha Centauri B (on the right), at a distance of 4.3 light-years from the Earth. The Alpha Centauri group is completed by a faint red dwarf, Proxima Centauri (not shown), recently revealed to possess an Earth-like planet orbiting in its habitable zone.
Peering deep into the heart of our home galaxy, the Milky Way, the Hubble Space Telescope reveals a rich tapestry of more than half a million stars. Most of the stars pictured in the image are members of the Milky Way nuclear star cluster, the densest and most massive star cluster in the galaxy. Hidden in the centre is the Milky Way’s resident supermassive black hole.
