Messier 71 is a globular cluster in the constellation Sagitta, discovered by Philippe Loys de Chéseaux in 1745. It is about 13,000 light years away from Earth and has a mass of about 53,000 M☉ and a luminosity of around 19,000 L☉.
Messier 71 is a small and ancient globular cluster of stars on the edge of our galaxy, located 13,000 light-years from Earth. Learn about its history, structure, and appearance in this Hubble image and star chart.
Messier 71 (M71) is a faint and loose globular cluster of stars in the constellation Sagitta, the Arrow. It was discovered by de Chéseaux in 1746 and added to Messier's catalogue in 1780.
This Hubble image of M71 was created from images taken with the Wide Field Channel of the Advanced Camera for Surveys on Hubble. taken through yellow (F606W — colored blue) and near-infrared (F814W — colored red) filters. The exposure times were 304 s and 324 s respectively. The field of view is about 3.4 arcminutes across. M71 is located roughly 13,000 light-years from Earth in the ...

Messier 71 is a loose and metal-rich globular cluster in the constellation Sagitta, located 13000 light-years away from Earth. It has around two dozen variable stars and can be viewed with binoculars or a small telescope.
M71 is a 10 billion year old globular star cluster in the constellation Sagitta. Learn how interstellar dust affects the colors and brightness of its stars and how to correct them using a Color-Magnitude diagram.
For a long time, the classification of M71 was a dense open cluster, but nowadays it's pretty inconclusive, with little study to help astronomers understand exactly what the M71 is. One of great importance was in 2008, when Brazilian astronomer Alan Alves-Brito and his colleagues published a study entitled "Abundance variations in globular ...
Messier 71 is a small but bright cluster of ancient stars on the edge of our galaxy, 13 000 light-years from Earth. It was first discovered in the eighteenth century and its nature was debated until recently.
M71 is strange because it looks exactly like an open star cluster when observed or photographed. In reality, Messier 71 has been officially classified as being a very loose open cluster. A similar object in the Messier catalog would be Messier 68 (although it does look like a globular cluster when photographed), which we yet have to capture.
