A new analysis of 523 Starlink satellite reentries between 2020 and 2024 has tied faster-than-expected orbital decay directly ...

Ultra-hot Jupiters (UHJs) are some of the most fascinating astronomical objects in the cosmos, classified as having orbital periods of less than approximately three days with dayside temperatures ...

NASA’s effort to save the Swift space telescope from an uncontrolled reentry has crossed a critical threshold: ground teams ...

It's getting crowded up there. Over the past few years, the advent of SpaceX's Starlink and other players in the mega-satellite constellation game are adding an exponential load of satellites and ...

Scientists are learning more about how the upper atmosphere and ionosphere affect space satellites as well as communications and navigation here on Earth, thanks to new data from a U.S. Air Force ...

The condemned planet could help answer questions about the fate of other worlds as their solar systems evolve. For the first time, astronomers have spotted an exoplanet whose orbit is decaying around ...

Macquarie University astronomers have tracked an extreme planet's orbital decay, confirming it is spiralling towards its star in a cosmic death dance that could end in three possible ways. The ...

As described in Chapter 1, the number of cataloged space objects has increased nearly linearly since 1960, at an average rate of about 220 objects per year. New spacecraft, the mission-related debris ...

When the Sun reaches higher levels of activity, junk drifting in low Earth orbit loses altitude at an increased rate — and for the first time, scientists have measured that increase and identified ...
