Despite the fact that nights are shorter because there are more daylight hours and contrary to logic, summer is a perfect season to see astronomical phenomena. Few, yes, precisely for this reason: because there is more light and more daylight hours, they are more difficult to produce.

But the few that there are can be seen clearly because summer, which officially began on June 21 at 4:58 p.m., is usually accompanied by clear skies.

Thus, after the change of season and the summer solstice -the longest day of the year- the first full moon has arrived, which is also the first summer supermoon. Known as the deer moontook place on July 3.

The Delta Aquarids They are shooting stars visible at a average height of 100 kilometers, and that can be enjoyed from areas with low light pollution. The area where the fleeting ones appear to come from occurs in the Aquarius constellation.

Less intense and less visible

Compared to the Perseids it is a less intense rain in terms of the number of meteors observed, but since they are slower, longer and with more persistent trails, they can produce a greater visual impact in the observer. On the night of the last day of July, the moon will be 95.6% full (on July 17 it will be in a new phase), which will make it difficult to observe the aquarid rain.

On August 1 comes the second supermoon of summer, the sturgeon moon. It is called the sturgeon because it is the time when Native Americans fished more easily That large fish in the great rivers and lakes of the country.

In the specific case of the Perseids, the fragments come from the Comet 109P/Swift-Tuttle that, at a certain moment, comes into contact with the Earth’s atmosphere. Although it has not been scientifically proven, it is speculated that the term perseids could be related to perseus constellation. The fact that the moon is at 10% of its phase will mean that, if the skies are clear, the rain can be easily observed.

Saturn and its rings, visible

the night of August 27th Saturn reaches its opposition, being brighter than at any other time of the year. This will be the perfect night to view and photograph the planet and its rings.
