There are definitely things that I study as an astronomer from billions of light years away that would be far more convenient to study up close, so there are definitely galaxies, black holes, stars etc that I’d like to visit, but I’m quite attached to Earth so would always want to come home. The trouble is that for any practical method of travel that does not violate the laws of physics as we currently understand them, space travel would be extraordinarily tedious. The closest star is ~4 light years away, so takes 4 years at the speed of light (30,000 km/s). Assuming you could travel at even 10% the speed of light in a spaceship (3,000 km/s), which is very fast indeed, it would take 40 years to get there, half a lifetime. So, you have to travel a long way and don’t get to see much along the way.
