摘要
描述Snakes and Stones NGC 4194.jpg |
English: The galaxy pictured in this Hubble Picture of the Week has an especially evocative name: the Medusa merger.
Often referred to by its somewhat drier New General Catalogue designation of NGC 4194, this was not always one entity, but two. An early galaxy consumed a smaller gas-rich system, throwing out streams of stars and dust out into space. These streams, seen rising from the top of the merger galaxy, resembles the writhing snakes that Medusa, a monster in ancient Greek mythology, famously had on her head in place of hair, lending the object its intriguing name. The legend of Medusa also held that anyone who saw her face would transform into stone. In this case, you can feast your eyes without fear on the centre of the merging galaxies, a region known as Medusa's eye. All the cool gas pooling here has triggered a burst of star formation, causing it to stand out brightly against the dark cosmic backdrop. The Medusa merger is located about 130 million light-years away in the constellation of Ursa Major (The Great Bear). |

JPEG文件备注 | The two galaxies pictured in this Hubble Picture of the Week have an especially evocative name: the Medusa merger.Ê Often referred to by its somewhat drier New General Catalogue designation of NGC 4194, this is actually not one entity, but two. These are galaxies in the turbulent throes of merging togetherÑÊ scrambling their original shapes and taking part in a dramatic cosmic wrestling match, they are throwing out streams of stars and dust out into space as they grapple. These streams, seen rising from the top of the merging galaxies, resemble the writhing snakes that Medusa, a monster in ancient Greek mythology, famously had on her head in place of hair, lending the object its intriguing name.Ê The legend of Medusa also held that anyone who saw her face would transform into stone. In this case, you can feast your eyes without fear on the centre of the merging galaxies, a region known as Medusa's eye. All the cool gas pooling here has triggered a burst of star formation, causing it to stand out brightly against the dark cosmic backdrop.
