A gas cloud has been spotted approaching the Milky Way's central black hole. Observations of its closest approach, expected to occur in mid-2013, may offer insight into the black hole's immediate surroundings. See Letter p.51 The radio source Sgr A* in Sagittarius is thought to be the site of a supermassive black hole lying at the centre of the Milky Way. A study of stellar orbits has identified an object moving towards Sgr A* at a speed of 1,700 kilometres per second. Its low temperature and… Expand

Multiwavelength study of the flaring activity of Sagittarius A in 2014 February−April
Context. The supermassive black hole named Sgr A* is located at the dynamical center of the Milky Way. This closest supermassive black hole is known to have a luminosity several orders of magnitudeExpand
Astrophysics: Mystery survivor of a supermassive black hole
The G2 cloud in our Galaxy's core has survived an encounter with the central black hole and failed to trigger a major flare-up in the black hole's activity. A promising theory endeavours to explainExpand

TLDR
The presence of a dense gas cloud approximately three times the mass of Earth that is falling into the accretion zone of Sagittarius A*, a compact radio source at the Galactic Centre, is reported. Expand
