We are firmly in the era of the satellite constellation—groups of dozens of similar satellites—and are currently entering the era of the mega constellation, wherein groups of thousands of satellites swarm the skies. The clusters of satellites started small, but, like a viral outbreak, they grew almost without us noticing—and now we're dealing with a pandemic.
This system is truly extraordinary. We're seeing the radio equivalent of a laser halfway across the universe. Fundamentally, masers and lasers are focused beams of light in the same frequency. In the realm of astrophysics, these can arise from clouds of dust being excited into a higher energy state from the light emitted by other sources, like stars and black holes.
At the time the proposed telescope was one of three contenders to make a giant leap in mirror size from the roughly 10-meter diameter instruments that existed then, to approximately 30 meters. This represented a huge increase in light-gathering potential, allowing astronomers to see much further into the universe-and therefore back into time-with far greater clarity.
Your stargazing experience can differ greatly based on where you are in the world. That's due in part to light pollution, which can drown out all but the brightest stars and satellites in densely populated areas. For truly unforgettable celestial views, you'll need to visit one of the darkest places in the U.S. on a clear night. DarkSky is an Arizona-based nonprofit with the mission "to restore the nighttime environment and protect communities and wildlife from light pollution."
After years of traveling the globe in search of the darkest skies still possible in an increasingly bright world, I've learned something that surprises a lot of people: truly experiencing the night isn't just about where you go-it's about when you go. If I had to share just one astrotourism tip with travelers, it would be this: plan your trip around the new moon. It sounds almost too simple, but the difference it makes is dramatic. When the moon is absent from the night sky, darkness returns in a way that feels almost ancient. Stars multiply. Constellations become easier to trace. And in truly dark places, the Milky Way often reveals itself as a glowing, dusty band stretching from horizon to horizon.
There is a profound, quiet magic in standing alone under a truly dark sky, but the experience becomes something else entirely when shared with a community of fellow explorers. Star parties are the heartbeat of this experience: communal, high-energy gatherings where everyone from veteran astronomers to total beginners can share a wide-angle view of the cosmos.
