Most ISS watchers are satisfied with a bright streak across the evening sky — but a small group of dedicated observers chase something far rarer. When the space station passes directly in front of a bright star or planet, the result is a split-second cosmic alignment that demands precision, patience, and a little bit of luck.
Not everything gliding across your night sky is a functioning spacecraft. Earth orbit is packed with dead satellites, spent rocket stages, and forgotten hardware that's been circling our planet for decades. Here's how to find them, identify them, and appreciate them as the space archaeology they truly are.
Earth orbit is getting crowded, and the International Space Station has had more brushes with disaster than most people realize. From chunks of defunct satellites to rogue rocket bodies, the threats come fast and the response windows are sometimes measured in hours. This is the story of the maneuvers nobody planned for — and the systems working around the clock to make sure they never have to happen again.
Not every American gets the same view of the International Space Station, and your zip code has more to do with it than you might think. This regional breakdown explains why latitude, local geography, and seasonal timing combine to give some states a serious leg up on ISS spotting. Find out where your state lands in the pecking order — and how to make the most of whatever sky you've got.
The ISS is a fantastic entry point into the hobby, but the night sky holds dozens of phenomena that most station-watchers never bother to look for. From asteroid occultations to polar stratospheric clouds, here's what you're missing — and why your ISS skills already make you ready for it.
Most observers chase the long, lazy passes — but the ISS also delivers split-second solar and lunar transits visible only from a narrow strip of ground. Here's how the math works, which tools actually help, and how to put yourself in exactly the right spot before it happens.
NASA's pass prediction pages are packed with numbers — elevation angles, azimuth bearings, brightness magnitudes — but most casual observers just scroll past them to find the time. Learning to read that data changes everything about how you watch the ISS cross your sky.
You don't need a telescope, a tracking mount, or a thousand-dollar mirrorless body to photograph the International Space Station. With the right timing, a few tweaked settings, and some creative thinking, your smartphone or entry-level camera can pull off shots that'll genuinely impress you.
The ISS doesn't shine equally for everyone, and it definitely doesn't shine equally all year long. Understanding how the seasons, your latitude, and a few tricks of orbital geometry interact can turn a frustrating string of missed passes into a reliable viewing habit. Here's how to think strategically about when to look up — no matter where you live in the US.
The ISS gets most of the headlines, but it's no longer the only crewed laboratory circling Earth — and it won't be for much longer. From China's rapidly expanding Tiangong station to a wave of commercial platforms on the drawing board, the orbital neighborhood is getting crowded in the most fascinating way possible. Here's what's up there, why it matters, and how amateur observers can start tracking the new generation of space stations.
Ever wonder why the International Space Station blazes across your sky on Tuesday night but completely ghosts you by Friday? The answer lies in some surprisingly elegant orbital physics — and once you understand it, you'll never miss a pass again.
SpaceX, Amazon, and a growing list of tech players are filling low Earth orbit with thousands of satellites — and professional astronomers say the damage to ground-based science is already real. Here's what's at stake, who's pushing back, and what you can do about it.
