No, but it was considered. The reason parallax measurements weren’t taken with Voyager or any other interplanetary spacecraft is simply that astronomers can do better from the ground or with dedicated ...

Let’s try a demonstration that we all enjoyed in elementary school. Close one eye, hold out your thumb at arm’s length, and align it with an object on the other side of the room. Without moving your ...

Distance measured out to the far side of our Milky Way means that radio astronomers now can work on producing an accurate map of the full extent of our galaxy's structure for the first time.
