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 ...

Jupiter's red spot thickness remains steady as surface area decreases

A team of researchers affiliated with Aix-Marseille Université has found evidence that suggests the thickness of Jupiter's red spot has remained relatively stable as its surface area has decreased. In their paper published in the journal Nature Physics, the group describes how they estimated the thickness of the spot and why they believe it is not going to disappear anytime soon.
