Did you know that NASA takes a photo of the universe every day?

On the night of August 10th, our eyes are turned to the sky, hoping to catch a shooting star and make a wish. But unfortunately, especially if we are in the city, it has become increasingly difficult to observe this phenomenon, due to the smog. Searching the web for solutions and ideal places to observe the stars, we came across an even more interesting NASA site. So, if you are disappointed in your contemplative session tonight, we have news that may comfort you.
Did you know that every day NASA takes a picture of the universe? The Hubble Space Telescope, launched into Earth orbit in 1990, takes a picture of the Universe every day and NASA shares it with the world on this site.

The images have an extremely high resolution thanks to the telescope’s outer orbit. In addition to taking incredible photographs, the measurements obtained with the help of the Hubble have enabled NASA to make important discoveries. The age of the Universe, which was previously estimated at between 10 and 20 billion years, was corrected to around 13.7 billion. It was also possible to estimate the number of black holes and their spread to other nearby galaxies, in 2012 Hubble discovered Pluto’s fifth moon and in 2016 it detected the farthest galaxy from Earth ever recorded (GN-z11). In addition to Hubble, NASA uses other telescopes and observatories such as the Chandra X-ray Observatory and professional photographers.

But back to the photographs, the site allows you to search by day, month and year, so you can go in search of the day of your birth and discover the phenomenon observed that day! In addition, each photograph is accompanied by an explanation, here are some examples.
