Explanation: Stars of the globular cluster NGC 2419 are packed into this [6]Hubble Space Telescope [7]field of view toward the mostly stealthy constellation [8]Lynx. The two brighter spiky stars near the edge of the frame are within our own galaxy. [9]NGC 2419 itself is remote though, some 300,000 light-years away. In comparison, the Milky Way's satellite galaxy, the [10]Large Magellanic Cloud, is only about 160,000 light-years distant. Roughly similar to other large globular star clusters like [11]Omega Centauri, NGC 2419 is intrinsically bright, but appears faint because it is so far away. Its extreme distance makes it difficult to [12]study and compare its properties with other globular clusters that roam the halo of our Milky Way galaxy. Sometimes called "the Intergalactic Wanderer", [13]NGC 2419 really does seem to have come from beyond the Milky Way. [14]Measurements of the cluster's motion through space suggest it once belonged to the [15]Sagittarius dwarf spheroidal galaxy, another small satellite galaxy being disrupted by repeated encounters with the much larger Milky Way.
