StarX's Spacelink satellites get mixed up with star observations. Astronomers say "it's not cool!"



Clara Martinez-Vázquez, an astronomer at the Inter-American Observatory in Cerro Tololo in Coquimbo, Chile, tweets that the bright lights reflected by satellites interfere with a powerful camera used to monitor other galaxies.

"Wow! I'm in shock! A huge amount of Starlink satellites went through the sky tonight [the observatory]," she said. "Our exposure to DECam was badly affected by 19 of them! The Starlink satellite train lasted for over 5 minutes !! More depressing … That's not cool!"

SpaceX CEO Elon Musk began designing a project in 201
5 to strengthen on-site Internet connectivity. The hope is that more satellites will expand the bandwidth and range.

But astronomers fear that the lower the Earth's orbit, the more light will interfere with the observations of their telescopes.

Satellites on Earth

Satellites can be seen from Earth, thinking that they are usually quite dropped. But when their panels reflect the "flare" of sunlight back to Earth, they can look brighter in the short term, according to National Geographic.
These streaks of bright light can interfere with astronomical objects just below them and can cause false signals in telescopes, Nature reports.
In March, the Union of Interested Scientists announced that there are currently more than 2,000 satellites in orbit, ie. although this number does not include Starlink satellites.

The most visible, like the International Space Station, are in low Earth orbit and are easier to spot in summer when the sun is shining for longer periods – thus satellites have more time to reflect it.

And many, many more moons can join those already in orbit. SpaceX has authorized regulators to launch more than 10,000 satellites, and recently requested the addition of another 30,000.

In response to an initial riot in May, Musk claimed that Starlink satellites would not affect astronomical observations.

"There are already 4,900 satellites in orbit that people notice ~ 0% of the time," he tweets . "Starlink will not be seen by anyone unless it looks very closely and will have ~ 0% influence on advances in astronomy."

Reached by CNN on Wednesday, a SpaceX spokesman replied that it was talking to leading astronomy groups to find ways that satellites will not disrupt their work. On a more tactical level, this makes the primary color of Starlink satellites black, which it hopes to help. SpaceX says it can adjust some of the satellites' orbits if necessary.

In other words: they listen.
