The Night Sky Is In Danger And Astronomers Are Stepping Up To Protect It“A problem for us with light pollution on the ground is the ongoing world transition to LED technology, which has made light at night very inexpensive to consume,” Dr John Barentine, the Executive Officer and Principal Consultant at Dark Sky Consulting, told IFLScience. “In the last decade, the brightness of the night sky has been rising around the world on the order of about 10 percent per year on average.”
“We don't want to roll back any progress,” Dr Barentine explained. “The satellite operators have a right to be in space, just as we have a right to access space for astronomy purposes. So we're actively working with them to try to find a solution that is as much of an agreement on the basics as we can reach to where they're able to conduct their activities without causing undue interference to what we're doing.” SpaceX's new direct-to-cell Starlink satellites are way brighter than the originalsWhile DTCs are brighter objects, they move at a faster apparent rate and spend more time in Earth's shadow than regular Starlinks, which would offset some of their negative impact on astronomy observations, the study noted.
"I see it as a tradeoff in parameters rather than an absolute better/worse kind of situation," John Barentine, a principal consultant at Arizona-based Dark Sky Consulting who was not involved with the new study, told Space.com. |
