NASA Scientist to Discuss "The Science of Interstellar" at Library of Congress Lecture This is an image of an accretion disk around a black hole, as seen by an observer nearly edge-on to the disk. According to Professor Brand the 3 potential planets (designated Miller, Edmunds and Mann) are in another galaxy.
Interstellar travel is between stars within a galaxy.
By 1989 it had visited Jupiter and Saturn, and crossed the orbits of (but did not visit) Uranus, and Neptune. Voyager 1 was launched in 1977. NASA's Voyager 1 probe broke through the sun’s magnetic bubble to touch the interstellar wind. Interstellar location: the cavernous space facility: Westin Bonaventure Hotel, South Figueroa Street, Downtown Los Angeles The cavernous interior of the NASA facility, with its circular balconies, is the enormous lobby of the Westin Bonaventure Hotel , 404 South Figueroa Street , downtown Los Angeles . Humanity’s great leap into the space between the stars has, in a sense, already begun. The extreme gravity of the black hole bends the light from the disk, forming … Humanity’s great leap into the space between the stars has, in a sense, already begun. After the initial detections of the comet, Scout system, which is located at NASA's Jet Propulsion Laboratory in Pasadena, California, automatically flagged the object as possibly being interstellar. This required both Cooper's Endurance mission and the previous Lazarus mission to travel from our galaxy to another - which would be defined as intergalactic travel.
In the summer of 2012, a NASA spacecraft named Voyager 1 became the first human-made object to enter interstellar space.
