Spitzer spots cosmic bubbles generated by massive young stars

The sheer energy of newborn, massive stars produces cosmic bubbles of gas and dust stretching tens of lightyears across.

This colourful cosmic view shows clouds of gas and dust in space that are expanding like bubbles due to the radiation outflow of massive young stars.

Each of these bubbles is about 10-30 lightyears across and filled with hundreds to thousands of stars.

The region is found in within our galaxy the Milky Way, in the constellation Aquila.

The image was captured by the Spitzer Space Telescope before it was placed in safe mode in January 2020, ending its 16-year mission.
