It has a low surface brightness and is somewhat difficult to observe visually, but is an impressive object for astronomical long exposures. Instead, this nebula is a great target for astrophotographers. The star that most likely provides the high-energy starlight that ionises much of the nebular gas is the bright, hot, bluish Xi Persei just … Read more
And they have detected faint traces in the galaxy’s halo – a vast region of space around the disk. The streams, recorded only in very deep exposures, likely represent the ghostly trail of a dwarf galaxy – debris left behind along the orbit of a smaller satellite galaxy that was gradually torn apart and merged … Read more

The polar ring component can also be used to probe the shape of the otherwise invisible dark matter halo by calculating the gravitational influence of the dark matter on the rotation of the ring and disk. It is the only galaxy of its kind to have a “lenticular late-type galaxy” as a host. ngc 660 … Read more
