spiral galaxy

This is because radio telescopes have always struggled to see the much fainter radio emission from normal spiral galaxies like our own Milky Way.

EMU sees almost all the spiral galaxies in the nearby universe that were previously seen only by optical and infrared telescopes.

Another new Hubble image shows a large spiral galaxy that lies 490 million lightyears away.

Many spiral galaxies, including the Milky Way, contain a central bar-shaped region densely packed with stars and surrounded by the galaxy’s pinwheeling arms.

Different parts of spiral galaxies tend to host different types of stars.

Case in point: the spiral galaxy NGC 5548, which astronomers have been monitoring off and on for decades.
