|Locations: Carina-Sagittarius Arm (toward the Galactic centre)|
The Carina-Sagittarius Arm is generally thought to be a minor spiral arm of our home galaxy, the Milky Way. Each spiral arm is a long, diffuse curving streamer of stars that radiates out from the galactic center. These gigantic structures are often composed of billions of stars and thousands of gas clouds. The Carina-Sagittarius Arm is one of the most pronounced arms in our galaxy, as a large number of HII regions, young stars, and giant molecular clouds are concentrated in it. The Carina-Sagittarius Arm lies between two major spiral arms, Scutum-Centaurus Arm inside and the Perseus Arm outside.
The Sagittarius Arm is divided into two parts. Curving outward from the galaxy's central bar is the Sagittarius Arm (Sagittarius bar), which further outward becomes the Carina Arm.
Noteable locations: Elysium
- The Digital Mission Macross VF-X story takes place here.
- a rather loosely concentrated cluster of stars that measures 75 ly across.
- from Earth, appears about the same size as the Moon in the sky.
- At least 43 variable stars have been observed within M4.
- a very large (100-150 times as much mass as the Sun) and bright (about four million times that of the Sun) luminous blue variable (LBV) star.
- the star is surrounded by a large, bright nebula, known as the Eta Carinae Nebula, the Keyhole Nebula, or NGC 3372.
- as of July 2005, Eta Car is the 5th most luminous star yet discovered, and still the most massive.
- Mylene Flare Jiinasu, the 7th child of Maximilian and Miria Farina Jiinasu, born onboard the space carrier Red Moon in flight near the Nebula, on 2031.02.02.
- Radius: 1.0 ly
- a young bipolar planetary nebula in the constellation Norma that is composed of a bright core and four distinct high-velocity outflows that have been named lobes.
- composed of a giant companion that caused a central dense gas region to form, and a white dwarf that provides ionizing photons for the PN.
- PSR B1620-26
- a neutron star pulsar.
- 1.35 solar mass
- PSR B1620-26b
- a white dwarf companion.
- 0.34 solar mass.
- orbits at a distance of 1 AU about once every half year.
- PSR B1620-26c Methuselah
- a planet orbiting the primary and secondary in a circumbinary orbit. This makes the system the only triple system radio pulsar, and the only triple system in a globular cluster known thus far.
- mass: 2.5 times that of Jupiter
- orbits at 23 AU in an orbit similar to that of Uranus around the Sun, but slightly larger. Each orbit of the planet takes about 100 years.
