The rotational center of the Milky Way galaxy—it is a supermassive black hole about 4.100 million solar masses, which powers the compact radio source Sagittarius A*. It is 8.2±0.4 kiloparsecs (26,700±1,300 ly) away from Earth in the direction of the constellations Sagittarius, Ophiuchus, and Scorpius.

Even though most of the stars are old red giant stars, the Galactic Center is also rich in massive stars. More than 100 OB and Wolf–Rayet stars have been identified there so far. They seem to have all been formed in a single star formation event a few million years ago. The existence of these relatively young stars was a surprise to experts, who expected the tidal forces from the central black hole to prevent their formation. This paradox of youth is even stronger for stars that are on very tight orbits around Sagittarius A*. The scenarios invoked to explain this formation involve either star formation in a massive star cluster offset from the Galactic Centre that would have migrated to its current location once formed, or star formation within a massive, compact gas accretion disk around the central black-hole. Current evidence favors the latter theory, as formation through a large accretion disk is more likely to lead to the observed discrete edge of the young stellar cluster at roughly 0.5 parsec. Most of these 100 young, massive stars seem to be concentrated within one or two disks, rather than randomly distributed within the central parsec. Star formation does not seem to be occurring currently at the Galactic Centre, although the Circumnuclear Disk of molecular gas that orbits the Galactic Centre at two parsecs seems a fairly favorable site for star formation. There is also a "conundrum of old age" associated with the distribution of the old stars at the Galactic Centre. The density of the old stars peaks at a distance of roughly 0.5 parsec from Sgr A*, then falls inward: instead of a dense cluster, there is a "hole", or core, around the black hole.

A vast, deep, open jet-black hole. A beautiful, yet heartrending enigmatic melody flows from the depths of the dark hole that fills the center of the galaxy. Unknown if this music is merely a natural development, or if intelligent life lives on the other side of the dark hole. In order to confirm what's causing it, the Megaroad-01 fleet entered the Dark Hole, without knowing if they'll be able to return to our galaxy again.

It is made of several dust and gas clouds, which orbit and fall onto Sagittarius A* at velocities as high as 1,000 km per second. The surface layer of these clouds is ionized. The source of ionisation is the population of massive stars that also occupy the central parsec. Sgr A West is surrounded by a massive, clumpy torus of cooler molecular gas, the Circumnuclear Disk (CND). The nature and kinematics of the Northern Arm cloud of Sgr A West suggest that it once was a clump in the CND, which fell due to some perturbation, perhaps the supernova explosion responsible for Sgr A East. The Northern Arm appears as a very bright North–South ridge of emission, but it extends far to the East and can be detected as a dim extended source. The Western Arc is interpreted as the ionized inner surface of the CND. The Eastern Arm and the Bar seem to be two additional large clouds similar to the Northern Arm, although they do not share the same orbital plane. They have been estimated to amount for about 20 solar masses each. On top of these large scale structures, many smaller cloudlets and holes inside the large clouds can be seen. The most prominent of these perturbations is the Minicavity which is interpreted as a bubble blown inside the Northern Arm by the stellar wind of a massive star, which is not clearly identified.

Macross 7, Macross 7 Dynamite, and Macross Frontier all take place in this area. The exact locations of the star systems and planets aren't known.

A binary star system. A strong solar wind blows in the system.

A habitable planet discovered by the Macross 5 Fleet in 2045. However, it imploded due to the Protodevilun Gigiru rampaging out of control. Protoculture ruins lay dormant on the planet.

A habitable planet discovered by the Macross Frontier and Macross Galaxy Fleets in 2059. The homeworld of the alien Vajra creatures. It was discovered in 2059. It is one of the few A-class habitable planets. It is also known that the Macross Frontier Fleet—having won the battle against the Macross Galaxy Fleet—has begun colonizing the planet. It is also noteworthy that there is a large amount of Fold Quartz, a rare substance, on the planet.

A habitable planet discovered by the Megaroad-13 Fleet in 2025.

A remote planet inhabited by the Zolans in the 67th Planetary District. Planet Zola already had its own humanoid race—the Zolansand culture when it was discovered by humans from Earth. Zolans have a sac-like organ in their abdomen. However, their other body structures and intelligence are the same as those of Earth's humankind. It appears that they could also mate with Earthlings. If a Zolan from planet Zola used a Miclone Device, they could also become giant-sized. The Zolans wear a symbiotic creature—called a Cat-Snakey—around their necks. Zolans have a Zola-specific language. Given that the letters are also unique, some of the models of computers used on Zola display the Zolan language. However, the letters currently used are different from the old ones, and it seems that only the symbiotic Cat-Snakey are able to read the old letters. The cultural level in the late 2040's is close to that of developed countries on Earth in the first half of the 20th century (Zolans have radio, but they don't have television, and so on and so forth). However, they seem to have obtained spacecraft and VFs through contact with Earth's humankind, and there is a bias toward them in the Zolan's technological level.
