It’s not a surprise that the Arctic has seen an abundance of lights, but how long has it been that the region has had them?
That’s because light pollution is not the only issue with light pollution, according to a new study.
In the Northern Hemisphere, researchers from the University of British Columbia and the University and College London have determined that over time the Northern Lights region has lost around 20 percent of its natural light, meaning that the amount of sunlight reaching the atmosphere has increased.
“There are more than 100,000 stars in the sky, and in the Northern Light region of the sky there are about 40 percent fewer stars than in the Southern Light region,” said David Leffler, a professor of astronomy at the University at Buffalo.
“In other words, in the Arctic, we’re getting a lot less light from the Northern lights than in other parts of the world.”
Leffler and his colleagues are currently working on a follow-up study, which will focus on how the amount and intensity of the light pollution affected the stars in their survey.
“The northern lights are a pretty unique and unique constellation, so this is an interesting study in terms of what they’ve found and what we’re doing to understand their impacts,” said Leffer.
“If we can get some data on how they change, we’ll know a lot more about what is going on in the northern lights.”
Leiffler is also excited by the possibility that a future study could determine if there’s any potential for new light pollution regulations.
“If the regulations that we have now are effective in controlling emissions and the CO2 that we produce, then I think it could be a way to develop a lot of different things in the future, and I think the Northern Star Initiative is a good place to start,” said Leonie J. Jett, a senior lecturer at the School of Physics at the Australian National University.
“This research has shown us that there is a lot that we don’t know yet about the impacts of light pollution on the Northern Stars, so I think we’re very interested in seeing what these future studies show.”
In addition to the study, the researchers also have some other data that may help to understand the effects of light on the stars.
They found that the light from a star’s innermost star is about five times more intense than the light coming from the star’s outermost star, and the stars closest to the sun are also about 30 percent brighter than those in the southern sky.
These data, combined with previous research, suggests that a star can produce more light than the Northern stars do, and this may lead to the Northern star having a greater capacity for light pollution.
“We’re trying to learn how much light the NorthernStars produce and how that changes over time, and then we’re going to figure out how to mitigate that,” said Jett.
