Why can't you see the Stars in the first picture a few months later?

You may not see the stars in the first picture a few months later due to changes in atmospheric conditions, such as increased light pollution or cloud cover. Additionally, the position of the Earth in its orbit can affect which stars are visible at different times of the year. Seasonal variations and the angle of the Earth’s tilt can also cause certain constellations to be obscured or rise and set at different times.
