Mysteries in the Sky: What's That Up There?
Ever looked up at the night sky and wondered what those strange lights are? You're not alone! WTOP Newsroom has been flooded with calls from curious sky watchers, and thankfully, we have a space expert to shed some light on the subject.
Nighttime reveals a dazzling display: meteors, airplanes, the ethereal aurora, twinkling stars, planets, and, of course, satellites. But here's where it gets interesting: there are a lot of satellites. Over 11,000 are currently orbiting Earth, and a significant portion of these belong to Starlink. These satellites, launched by SpaceX, are designed to provide low-cost internet access around the globe.
When SpaceX launches a new batch of Starlink satellites, keep an eye out! They often appear as a striking "train" of lights moving across the sky. It's a truly captivating sight.
If you're curious about what you're seeing, you can use apps on your smartphone to track and identify these celestial objects.
WTOP's space expert, Greg Redfern, joined us to explain what's happening in the night sky. Here's what he had to say:
Linh Bui: We've been receiving calls into the WTOP newsroom reporting phenomena in the sky that people cannot explain.
- Listener: "I looked out to the west from my driveway, and I saw what I thought at first were three stars perfectly lined up, but I knew they couldn’t be stars. And as I watched them, I realized that they were moving up, sort of not quite exactly straight up, but at a slight angle. And as they moved up, they faded out. So I know that those are satellites, and I saw at least six of these in a straight line, all perfectly aligned going up. So I wondered, why are they? Who’s putting up those satellites? I have never seen a whole bunch of satellites all in a perfect line."
Greg Redfern: "Our listener perfectly described a train of SpaceX Starlink satellites. This constellation is deployed worldwide to provide low-cost internet. These trains of star-like satellites are usually seen shortly after a launch from a Falcon 9, where they are deployed in orbit. I myself have imaged and seen at least 25 of them at once. It's a common sight, but when people see it, they often ask, 'Wow, what is that? Is that an X-File?'"
Linh Bui: And do you think these sightings are going to become even more common going forward?
Greg Redfern: "Absolutely, because Starlink wants to put up 10,000 plus these satellites. Right now, there’s about 11,000 plus satellites in orbit around our planet that are active, and of that, over 8,000 of them are Starlink satellites. These are small. They weigh about a half a ton, but they do present a risk for orbital collisions, as well as polluting the nighttime sky for astronomers who are trying to take long exposures as part of their observing run. So it is something has to be addressed. And by the way, there’s more coming, because more people are getting into the satellite internet craze."
Linh Bui: I saw online that if you want to see the satellites, they do have a tracker available.
Greg Redfern: "People can get apps for their phones. Lynn, that can track satellites and the sky and so forth. And I highly recommend anyone that likes to look at the nighttime sky invest in a planetarium or a satellite tracker. They’re not expensive, easy to use, and they’re really quite fun to use."
The Growing Satellite Presence
The increasing number of satellites, particularly Starlink, raises some interesting questions. While providing internet access is beneficial, the sheer volume of these objects poses potential risks.
