Summary
[edit]DescriptionM77 (noao-m77pelletier).jpg |
English: M77 is a tremendous galaxy in the constellation of Cetus. It is over 170,000 light years across (the largest Messier galaxy) and over 49 million light years away. In this image you can see the very bright center and if you dim the lights in the room you can just make out the very dim outer arms. M77 is also remarkable because its central region emits copious amounts of energy. It is believed that the only source that could generate this amount of energy is a supermassive blackhole (as if a run-of-the-mill blackhole wasn't enough). In fact, the entire nucleus of this galaxy changes in brightness in a period of less than a week!. An energetic galaxy such as this falls into a special category called Seyfert galaxies (named after the discoverer Carl Seyfert). The galaxy is also a very strong radio source (for the reasons above). There have been more astronomical papers written about this galaxy than any others!This image was taken as part of Advanced Observing Program (AOP) program at Kitt Peak Visitor Center during 2014. |
