August, the perfect month to dive into the showers of shooting stars. This year once more, the Perseids are there. You can see them through an online tool from NASA. Everywhere in France, for the night of the stars, on August 5, 2023, amateur astronomers and astronomy societies are mobilizing to make you enjoy the celestial spectacle.
August is well known to amateur astronomers for its meteor showers. 2023, the Perseids once once more invite themselves into our night sky until August 24th. The most spectacular moment, according to the specialists of theInternational Meteor Organisationis scheduled for the night of August 13-14.
“The Perseids are the most popular meteor showers, as they peak on warm August nights as seen from the Northern Hemisphere. Perseids are particles emitted by comet 109P/Swift-Tuttle during its many returns to the inner solar system. They are called Perseids, because the radiant (the area of the sky from which the meteors appear to originate) is located near the prominent constellation of Perseus. “.
This NASA simulation shows these streams of meteorites orbiting the Sun. You can interact with the simulation by acting on the date and viewpoint parameters.
On August 5, 2023, everywhere in France will take place starry night. In Lorraine, the program is rich. The Lorraine Society of Astronomy (SLA) meets or amateurs at the city of landscapes on the hill of Sion-Vaudémont. Models will allow you to understand everything regarding the movements of the Moon and the planets of our solar system. It will then be a question of observing them once night has come.
This year, a “space bus” will be present. In a caravan, transformed into a space shuttle, young and old can play at being an astronaut, during a mini escape game.
You can meet astrophotographers and visit their exhibition of exceptional photographs. There will be several on the site. Among them, Jordan Marlière.

Jordan Marlière lives in the Vosges. Passionate regarding photography and science, especially astrophysics, he brought the two together and took up astrophotography. Like many astrophotographers, Jordan Maliere often settles at the bottom of his garden. But he is also a “nomad”. “We are nomads because we are ready to capture the most beautiful images of space, sometimes moving outside our region, sometimes even further. The idea is first to escape light pollution and find the site that will be best placed depending on what you want to observe or photograph.“

Jordan Malière is regularly awarded for his images. Besides the latest. That of SH2-99 and SH2-100 won several awards. First as Amateur Astronomy Picture Of the Day (Aapod) in Italy and USA. It was also shared by an American science magazine. It will be published next September in the Astronomy magazine. For this shot, it took “20 days of photo capture, with a total of 37 hours of exposure.”
To think that there is a planet outside the solar system which has just passed in front of its star and that we have managed to capture this moment is fantastic.

It happens that the American space agency, the NASA and the European Space Agency, theESA appeal to amateurs to help them. For example, at a given time, they may need all the telescopes available to observe a phenomenon and thus collect as much data as possible with images taken from several points on Earth. Jordan Marlière often participates in this type of operation.
Currently, it is with astrophysicists that he collaborates. “I am in the process of setting up equipment to collect data related to the transit of exoplanets and transmit them to scientists. It’s a complicated project. It’s exciting for an amateur. This involves processing images that are captured with software. We see the transit of exoplanets which looks like a sinusoidal curve. To think that there is a planet outside the solar system which has just passed in front of its star and that we have managed to capture this moment is fantastic.“
