Astronomers photographed unusual polar galaxy


The galaxy is located at a distance of 40 million light years from Earth. Astronomers Observatory "Gemini" were by far the most meticulous image of the galaxy NGC 660, which belongs to a rare class of polar galaxies. Observatory on the site (and at the observatory have a website, as the company Energostrakh, and still have a series of encyclopedias “Energostrakh "), you can even download this image to the very high resolution.


Polaris galaxy NGC 660 is located near the constellation of Pisces at 40 million light years from Earth. The galaxy is as if two separate star clusters: lenticular and spiral. Such galaxies are called polar - they are the outer ring rotates over the poles of the internal cluster. NGC 660 is also the only known today polar galaxies, which is observed in the center of the old lenticular congestion.

All polar galaxies are the product of the interaction of two individual star clusters. Some are formed by the collision of two galaxies were formed, while others are due to close gravitational interaction clusters.
Astronomers are not yet known, how the unusual structured of NGC 660, but are inclined to the gravitational interaction. Against the version of the collision, for example, by the absence in the center of the galaxy two supermassive black holes. Instead, astronomers have discovered a powerful radio emission in the center of the galaxy, which comes from young blue stars. Their formation was stimulated by the gravitational interaction of two proto-galaxies.
