It is one of only four star systems known to be hydrogen-deficient, which makes it difficult to classify U Sgr. This image is a tiny part of just one of eleven public surveys of the sky now in progress using ESO telescopes. The sign, which is represented by the archer's arrow, is ruled by Jupiter. Chiron was wise and skilled not only in the arts of war but also healing and philosophy. It is one of the nearest globular star clusters to Earth. The several star forming regions that make up W31 are located at different distances, but appear together in the sky because they lie in the same line of sight when observed from Earth. Vast amounts of energy are also released when these stars go out as supernovas, heating the surrounding material. It was discovered by William Herschel in 1784. It belongs to the spectral type B9V. Because it has an imposing size and energy, Sagittarius A East is believed to be a remnant of a star that came close to the central black hole and was gravitationally compressed. The cluster was discovered by Charles Messier in 1778. In this image of ESO 456-67, it is possible to see the various layers of material expelled by the central star.
