Do you see a whitish broad band like white glowing path across the sky on clear starry night?

Yes, what you're seeing is the Milky Way, our home galaxy. The Milky Way appears as a whitish band of light in the night sky due to the combined light of billions of stars that reside within it. These stars stretch across the sky in a plane, forming a visible band.

When observed from Earth, the Milky Way appears to curve across the sky, and its brightest part can be seen in the constellation Sagittarius during the northern hemisphere summer months. The Milky Way is a spiral galaxy, and from our perspective within it, we see the galaxy as a bright band because we are located within one of its arms.

The center of the Milky Way galaxy cannot be seen directly as it lies behind a thick concentration of dust and gas, but its influence can be detected through the observation of stars, nebulae, and other celestial objects within our galaxy.

The Milky Way is a vast and awe-inspiring sight, visible on a clear dark night away from city lights. It serves as a reminder of our place in the universe and the countless stars that form this magnificent galaxy.
