Under the spell of the Milky Way. International Dark Sky Week

Imagine standing under a sky so dark that the Milky Way stretches across it like a luminous ribbon. This is the experience that International Dark Sky Week aims to bring back. Every April, during the week of the new moon (this year from April 21 to 27), we are invited to turn off our lights and gaze at the stars. The event was initiated by Jennifer Barlow, an American high school student, in 2003, to combat light pollution. One of the best places to experience the night sky's beauty is in the United States, in Joshua Tree National Park in southeastern California, which is an International Dark Sky Park. Here, the absence of artificial light allows visitors to see the stars as our ancestors once did. Did you know that light pollution prevents us from seeing most of the stars in the Milky Way? By reducing it, we can reconnect with the universe's beauty and wonder.
