Triangle Galaxy: Awesome Photography by Hubble - Popular Mechanics

Full year telescope "Hubble took photographs of an unusual Triangle system – one of the neighbors of the Milky Way – and finally astronomers showed the world a fascinating image with high resolution.

Usually, when astronomers talk about a "neighboring galaxy," they mean the Andromeda galaxy, which is only 2.5 million light-years away. A little further (only 500,000 l.) There is another spiral galaxy, the third largest in the local group. Her name is the Triangle Galaxy and recently Hubble acquired one of the most detailed and fascinating photos of this amazing phenomenon:

Approximately 25,000,000 zvzed came into the lens, so that scientists can not only study the Triangle System, but also highlight some features of the Milky Way. The final image is the result of combining 54 images taken from February 2017 to February 2018, according to data from the Space Telescope Science Institute. Jagged "edges" are artifacts that are created by the specific location of the telescope camera.

Astronomers have established that the galaxy itself has about 40 billion stars and that the diameter is about 60,000 light years. By comparison, our Milky Way has hundreds (!) Billions of stars and its length is 150,000 light-years across. According to a new press release, Triangle Galaxy is now experiencing a stage of highly active star formation – about 10 times more intense than that of its neighbor, Andromeda Galaxy.
