Satellite Internet Providers Creating Light Pollution for Astronomers
SpaceX’s Starlink and other satellite internet companies are making light pollution worse for astronomers, according to a recent research article that appeared in Nature Astronomy. Since 2019, the number of satellites in orbit has more than doubled, and the report examines the repercussions of this phenomenon.
The expanding number of satellites in low Earth orbit, particularly for satellite internet constellations like Starlink, is causing considerable challenges for astronomers. The paper points out that the satellites’ dazzling reflections in the night sky interfere with observations and cause severe light pollution.
As a result, astronomers are calling on regulators to take action to fix the situation before it worsens. With SpaceX and other firms intending to launch tens of thousands of additional satellites into orbit, it is anticipated that the problem will only intensify.
Similar to telescope coatings, the report suggests that the solution may lie in developing a method to reduce the reflectivity of satellites. Moreover, launching fewer satellites and positioning them at higher altitudes could potentially help reduce the problem.
Satellite Internet’s Impact on Astronomy: Balancing Needs and Challenges
Yet, some critics claim that the remedy is not so straightforward. While deploying fewer satellites and relocating them at higher altitudes may lessen the impact on astronomy, it would also reduce the speed and dependability of satellite internet connections.
Elon Musk, CEO of SpaceX, has acknowledged the issue and claimed that the business is working to mitigate Starlink’s impact on astronomy. Yet, it remains to be seen what actual steps the corporation will take to solve the problem.
The growing number of satellites in low Earth orbit is causing significant light pollution, which is impacting astronomy. Authorities and satellite internet providers need to take action to fix the issue before it worsens, while also balancing the demand for reliable and high-speed internet connections.
