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 ...

HD 38170 is a magnetic B-type star, observations suggest

An international team of astronomers has conducted spectropolarimetric observations of four stars identified by the MOBSTER (Magnetic OB[A] Stars with TESS: probing their Evolutionary and Rotational properties) project. The study found that one of the investigated objects is a magnetic B-type star. The finding is detailed in a paper published April 21 on the arXiv pre-print server.
