This is the Carina Nebula, an interstellar cloud of dust, hydrogen, helium and other ionized gases. It lies within our own Milky Way galaxy, about 6,500-10,000 light-years from Earth. Like many nebulae, it is a star-forming region, and contains two of the most massive and luminous stars in our galaxy, along with multiple O-type stars. Our galaxy itself is estimated to contain 200-400 billion stars, and roughly ten times as many planets.
Andromeda in Infrared. It is the closest galaxy to the Milky way at about 250 million light years distant. It will collide with our own galaxy in a few billion years to create one massive galaxy. I wonder what will happen when the two super massive black holes at the centre of our galaxies collide?
Men go abroad to wonder at the heights of mountains, at the huge waves of the sea, at the long courses of the rivers, at the vast compass of the ocean, at the circular motions of the stars, and they pass by themselves without wondering. Saint Augustine
