Astronomers launch campaign to guard the dark night sky

Published:

Humanity is blinding itself with light and losing sight of the starry night skies that when guided our ancestors and filled them with wonder, based on the European Southern Observatory (ESO), and the international astronomy organization is doing something about it.

Greater than 80% of the world’s population has their view of the night sky curtailed resulting from light pollution, based on the ESO. The increasing variety of satellites in orbit are photobombing the views of skilled telescopes on the few remaining dark sky sites, akin to the Very Large Telescope the ESO operates in Chile.

In response the ESO has launched a campaign to coach people about light pollution and the negative impacts of satellite mega-constellations on each skilled and amateur astronomy. They launched a web site spelling out the issue and created a social media hashtag, #ProtectDarkSkies, to spread the word. In a Tweet posted Wednesday using the brand new hashtag, the ESO identified that about one third of humanity can now not see the Milky Way — the thick disk of our galaxy wealthy with dust and stars — within the night sky from where they live.

Light pollution, electric light from human settlement and industry, makes it harder to see the more subtle celestial lights of the night sky. A 2019 survey found that 57% of English people could pick greater than 10 stars within the night sky, while just 2% could pick 30 or more.

But light pollution goes further than cutting off views of the sky, based on the ESO campaign website.

“Light can intrude into bedrooms, distract drivers, and upset the natural body clock of animals,” the ESO website reads, noting human health can suffer with out a clear light-dark cycle. And within the natural world, “Flocks of migratory birds and dung beetles alike orientate themselves using the Milky Way, and are disorientated by light pollution.”

The lack of astronomical views is more dramatic than most contemporary urban dwellers may understand. In a graphic on the ESO website illustrating a measure of sunshine pollution generally known as the Bortle Scale, it shows just how much of the further universe is definitely visible with the naked eye when standing under a very dark night sky.

Much more problematic for skilled astronomers than light pollution are the swelling mega-constellations of low Earth orbit satellites, akin to those being launched by the UK’s OneWeb and the Starlink constellation of SpaceX. Firms plan to launch as many as 100,000 of those satellites in the approaching years, and astronomers worry that they may reflect sunlight in ways in which impairs necessary astronomical observations.

And within the case of the Starlink satellites, many observations have already been impacted by the long white streaks of satellites passing through a telescope’s view during a protracted exposure.

To combat these issues, the ESO has launched the Protect Dark Skies campaign and suggested recent lighting standards, noting that light pollution isn’t just any light, but “artificial light that shines where it’s neither wanted, nor needed.”

The ESO can be a member of the International Astronomical Union Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference, which was founded in April to assist coordinate efforts to check and mitigate effects of satellites on astronomy. The ESO has also petitioned the United Nations to take motion, resulting in a discussion of the difficulty of satellite interference on the UN Committee on the Peaceful Uses of Outer Space earlier in 2022.
