Stunning Milky Way Shines Above the Very Large Telescope: Space Photo of the Day – November 5, 2025

High in Chile’s Atacama Desert, the Very Large Telescope (VLT) is a key tool for astronomers. It helps them explore the universe, from distant galaxies to our own Milky Way. Operated by the European Southern Observatory (ESO), the VLT has made many groundbreaking discoveries in its time.

Recently, three of its large domes showcased a stunning view of the Milky Way, illuminated by a soft glow in the sky. This phenomenon, known as airglow, occurs due to chemical reactions in the upper atmosphere. These reactions produce faint light, which can display hints of green, red, or orange hues.

The Atacama Desert, located in the Andes Mountains, is one of the best places on Earth for stargazing. This is partly because it has very low light pollution. With urban growth and increasing satellite launches, many are concerned about how light pollution might affect observatories like the VLT in the future. Even remote locations, once free from artificial light, aren’t immune to this creeping glow.

Experts note that preserving dark skies is crucial not just for astronomy but for our cultural heritage. Astronomical societies emphasize that these dark areas allow both professional astronomers and stargazers to experience the wonders of the universe.

According to recent studies, nearly 80% of people in urban areas can’t see the Milky Way due to light pollution. This statistic highlights the urgency of protecting natural dark spaces. Organizations are increasingly advocating for measures to safeguard these stargazing havens.

In discussions on social media, many users express a deep appreciation for the night sky and urge efforts to combat light pollution. Community initiatives, like “Dark Sky Parks,” aim to raise awareness about the importance of dark environments for both science and enjoyment. It’s a reminder that appreciating our skies is a shared human experience.
