Explanation:
Blown by the wind from a massive star, this interstellar
apparition has a surprisingly
familiar shape.
Cataloged as NGC 7635, it is also known simply
as The
Bubble Nebula.
Although it looks delicate, the 10 light-year diameter
bubble offers evidence of
violent processes at work.
Above and right of the Bubble's center is a hot,
O star, several hundred thousand
times more luminous and around 45 times more massive
than the Sun.
A fierce stellar wind and intense radiation from that
star has blasted out the
structure of glowing gas
against denser material
in a surrounding
molecular
cloud.
The intriguing Bubble Nebula lies a mere
11,000 light-years away toward the boastful constellation
Cassiopeia.
This natural looking view
of the cosmic bubble is
composed from narrowband image data, also used to
create a 3D model.
