Earth's city lights streak by in this long-exposure photo taken by NASA astronaut Don Pettit on Oct. 24, 2024. The green glow of Earth's atmosphere is also visible on the horizon.

This fall, NASA released photos of astronaut Suni Williams—who is currently living on the International Space Station (ISS)—that triggered an onslaught of tabloid and social media rumors speculating about her health.

Leaks are affecting a key part of the International Space Station. NASA and Russia’s space agency, Roscosmos, are not seeing eye to eye about the level of risk.

The station has been leaking air for five years, and NASA is concerned that this might indicate a potential failure in the structural integrity of the International Space Station.

NASA and Russian officials disagree on the cause of a worsening leak on the ISS, raising safety concerns for astronauts.
