Another problem, explained in detail in the article linked below, is the switch from incandescent and fluorescent light bulbs to LED light bulbs. LED light bulbs use less energy and can save one a great deal of money over the lifetime of the bulb, but produce more light at the bluer end of the spectrum, thus decreasing astronomers ability to observe at these wavelengths. That's not good for those wanting to learn more about our cosmos.
Pollution is endangering the future of astronomy
There's not much to be done about this either. The use of LED bulbs will continue since they are cost effective and help limit the burning of fossil fuels. Astronomers and engineers will continue working on methods to allow astronomers to observe the night sky and I'm sure some technology will be developed that will help. I just find it ironic that a technology that allows us to light areas we need lit while using far less energy, is causing problems in another area of science.
