This is Venus, high in the morning sky, amid the faint pillar of light called the Zodiacal Light. The glow is sunlight reflected off cometary dust in the inner solar system.
Above is the centre of the Galaxy area of Sagittarius. Alan Dyer
EDIT: I thinkSince the "Starts With A Bang" image below is wrong. Using this calculator I find that Zodiacal Light lies in the eliptic north pole points to galactic longitude 96 and latitude 29ecliptic plane, which means that the orientation of the Solar system in the Galaxy is moresomething like this:
Since Scorpio is fairly close to the galactic center (Sagittarius), the NASA diagram looks about right.
According to Starts With A Bang! the orientation is like this, so the solar system is currently going edgewise in its direction of motion.
The Sun orbits the Milky Way with a speed of 230 km/sec and it moves through the local interstellar gas cloud approximately into the direction of Scorpio with a speed of about 25 km/sec. You may be interested
Since Scorpio is fairly close to the galactic center (Sagittarius), the Solar System is moving approximately edge-on through the gas cloud as in the latterNASA diagram. I don't know how the directions of these motions are related
