The luminous night sky full of stars is threatened by its existence. According to the researchers, pollution satellite suspected to be the cause. How come?
“For the first time in human history, we will no longer be able to see the night sky as we used to see it,” said Samanta Lawler, Professor of Astronomy at the University of Regina in Canada, expressing concern.
Quoted from CNN, Wednesday (13/4/2022), Professor Lawler’s concern was conveyed after observing the sky from his farm in Saskatchewan, Canada.
Up to now, the number of satellite that air in the sky reaches more than 5,000 pieces. That number is double the number of previous satellites recorded in 2017, which was around 2,500 only.
“This is worse than I thought. This change is happening very quickly,” said Professor Lawler.
Professor Lawler and his colleagues have predicted this in a scientific journal that he published in The Astronomical Journal.
In the journal, Professor Lawler wrote that in less than a decade (10 years), one in fifteen bright spots in the night sky is not a star, but rather a star. satellite which moves.
“Think about it. There are only 4,000 stars that you can see with the naked eye and if 200 of those move, it’s very different from the sky we used to see,” Professor Lawler explained.
For the traveler who loves astronomy, satellite like a nightmare because when viewed with a telescope, the celestial body will ‘contaminate’ space photos that researchers want to observe.
If there is no strict regulation related to this, for example by limiting the number or function, the satellites will have an impact on astronomical research.
“Looks like we’re about to make a transition like when cars first hit the road. At first you’ll see it with enthusiasm. Now suddenly you’re living next to a giant highway full of cars. That’s what happened with satellite and the night sky now, “Lawler closed.
