M17 – Omega/Swan/Lobster Nebula

zespaceblog:

What does a star factory look like, well, M17 is a perfect example. It contains the three main types of nebula, reflective (the blue light reflecting from hot blue stars), the red light from the dust and gas (mostly hydrogen) which glows red when bombarded by UV light, and the dark nebula, the dust which is foreground and hides in visible light what lies behind.

The whole structure lies across the backdrop of the centre of our own galaxy in the constellation of Sagittarius some 5-6,000 light years from Earth.

N44 Superbubble

spacevoyagerx:

N44 is a large, bright region of ionized gas located in the Large Magellanic Cloud, a satellite galaxy of the Milky Way.

It is often referred to as a “superbubble” because it is formed by the combined effects of stellar winds and supernova explosions from massive stars.

These processes create a large cavity in the surrounding interstellar medium, leading to the characteristic bubble shape.

The N44 superbubble is notable for its complex structure and the presence of young, hot stars, as well as regions of active star formation.
