Although the starry sky is something which has long captivated us, many never really realise that the stars visible in the night sky from a particular location on the earth’s surface change throughout the year.

This means that from Malta, for example, we do not see the same stars throughout the entire year, but they change gradually throughout the year.

The reason for this observation is mainly due to the earth’s orbit around the sun.

At any particular point in the orbit of the earth around the sun, half of the sky will be visible during the day and the other half will be visible during the night.

Since during the day the sun shines too brightly for the stars behind it to be visible, we can only see the sky which is visible to us during the night.

Six months later, however, the Earth would now be on the opposite side of its orbit. The stars which were visible in the night sky six months before would now be in the daytime sky, and thus we would not be able to see them.

The stars visible in the night sky would be those present in the daytime sky six months before, so they would have now become visible to us at night.
