Mars and Earth - Small difference & big consequences

Einstein's theory of relativity suggests that time is not a constant and can vary based on gravitational fields and speed. In a strong gravitational field, time moves slower compared to a weaker one. Since Mars has a weaker gravitational field than Earth, time actually flows slightly faster there.  This concept has implications for future space missions, as the timing of communication and operation of spacecraft will need to account for this difference in how time elapses on Mars compared to Earth. Missions may need to adjust their schedules, operations, and technology to ensure accuracy and synchronization with Earth. Basically, the moment you bring gravity and velocity into the picture, time stops behaving like the simple, universal tick‑tock we experience in everyday life. And you’re absolutely right: Mars’ weaker gravity means clocks there run a little faster than clocks on Earth. What’s fascinating is how small the difference is—and how big the consequences become ...

Cold planets exist throughout our Galaxy, even in the galactic bulge

Researchers combined observations and modeling to infer the distribution of cold planets in the Milky Way. The results suggest that this distribution is not strongly dependent on the distance from the Galactic center. Cold planets seem to be present throughout our Galaxy, even in the galactic bulge, where their existence was uncertain. The findings could improve our understanding of both planetary formation and its history in the Milky Way.
