humans have not yet sent a probe outside of the Milky Way galaxy. The Milky Way is a vast spiral galaxy with a diameter of approximately 100,000 light-years, and sending a probe beyond its boundaries is an extremely challenging task due to the immense distances involved.
To put things into perspective, the Voyager 1 spacecraft, launched in 1977, is currently the farthest human-made object from Earth. However, even after more than four decades of travel, Voyager 1 is still well within the confines of our own solar system. It has not yet reached the outer boundary known as the heliopause, where the influence of the Sun's solar wind diminishes and interstellar space begins.
Interstellar travel presents numerous technical, logistical, and technological hurdles that must be overcome to send a probe beyond the Milky Way. The vast distances, the need for long-duration power sources, and the communication challenges are just a few of the significant obstacles in undertaking such a mission. While scientific exploration of other galaxies is a topic of interest, it remains a goal for future space exploration endeavors.
