A growing swarm of Internet-beaming satellites continues in the growing Starlink planetarium launched by SpaceX Eye barrier and an obstacle for the astronomy community. A recent change made on the outer surface of satellites to reduce its visibility in the night sky has made a small difference – just not nearly enough to make it an issue to make astronomy observations.
Beginning May 2019, SpaceX has launched batches of its Starlink satellites – 60 at a time – with the ultimate goal of being the “mega planetarium” of some 30,000 small, Internet-beaming satellites.
Long after the first batch of StarLink satellites launched in 2019, astronomers were in no hurry to realize that the amount and reflection of the satellites made it visible in the night sky – a sure sign of light in the sky In form of.
Video! Get ready.

I know people are excited about those images of the SpaceX Starlink satellites train, but it gives me pause.
They are bright, and a lot of them are going to happen.
If SpaceX launches all 12,000, they will beat stars visible to the naked eye.

Satellites were so reflective that they were disrupting the complex work already being done Study of the universe In space observatories around the world.
America– Deformed Vera C Rubin Observatory in Chile There is a giant telescope that has been operating with a multibillion-dollar printtag for over two decades. It was designed to begin the deepest survey of the night sky in 2022. a report in Guardian, Astronomers are now wondering how the Starlink constellation will draw streaks on its images every night, and what might be hindering the process.

Important astronomical events can occur over a long period of time or in the blink of an eye. Astronomers need to make careful calculations, and find a correct place and time window to make these observations, and capture them on record.
While the satellites follow a straight and predictable path in the sky, several thousands of similarly bright luminosity satellites in the sky can be a major deflection for the stargazing and astronomy communities. Imagine a brightly lit train to explain why you are too conservative to observe the behavior of lions.
SpaceX attempted to address the issue. They Starlink satellite redesigned and responded External, after making all satellites – “Darksat” – less reflective. He also published a paper with proof that it Made the satellites quite blurred.
However, scientific American Report This change has made little difference, with DarkSat still bright enough to interrupt the survey of the sky during daytime or nighttime. The upgraded DarkSat appears half as bright as the original Starlink fleet, the report says, which is progress.
These pictures that I shot last evening, show 3 @SpaceX #starlink Satellites, including STARLINK-1130 “DARKSAT”, pass through the same part of the sky in 10 minutes time.
As can be seen, Starlink-1130 is clearly unconscious due to its reflection-reducing coating.@ planet4589 @TSKelso pic.twitter.com/5lnBJJIo1S

Although the lines of light in the form of satellites still pass overhead, it is still a challenge for astronomers to make uninterrupted observations of space objects and events.
University of Washington astronomer Meredith Rawls told SciAm If SpaceX continues without fixing the problem, it sets a precedent for other companies to follow suit and launch their own mega constellations in relation to the needs of the astronomy community.
If this issue persists, scientists may have no choice but to take Elon Musk at his suggestion of having observatories in orbit beyond the range of visible-blocking satellites.
