  • T Tauri

Main Waypoints Details

• Map Reference: Cl Pismis 24 1
  • Cl Pismis 24 1, is a binary system in the Pismis cluster within the NGC 6357 nebula. It was originally thought to be the most massive and luminous known star at an estimated 200 to 300 solar masses. However, later observations and scientific advancements allowed for it to be resolved that it was two stars orbiting each other, each still among the most massive and luminous known stars in existence respectively.
    
    Further observations since the in-game galaxy was made in 2013 also suggest that one of the stars may be a very compact binary of it’s own, but we have so far been unable to conclusively determine that.

  • POI 1: T Tauri
  • POI 2: Hind Variable Nebula
  • T Tauri is a variable star in the Taurus constellation, and the prototypical star of the T Tauri class of variable stars. It was discovered in October 1852 by John Russel Hind, after which it’s planetary nebula, the Hind Variable Nebula was also named. — Strangely enough despite being the prototype star of the T Tauri classe of stars, the in-game representation does not have them as T Tauri stars.

  • This is a system inside of a nebula with the only star being a black hole. This means the only source of light in the system is from the reflection of the nebula. For Odyssey players there are atmospheric planets within the system. Due to the nature of the system, the atmospheres end up being bands of black on the horizon, because even being as thin as they are, they are enough that they can block the small pittance of light coming from the nebula’s reflection if passing through at enough of an angle, which makes for an interesting sight to behold.

Main Waypoints Details

• Map Reference: PSR J1740-3052
  • PSR J1740-3052 is a young 570ms pulsar with an estimated age of only about 350 thousand years. It was originally though to have a companion star in a highly eccentric orbit with it with a mass greater than 11 times that of our sun. However later observations seem to discount that star being the companion star and instead a different star of much smaller radius and mass to be the actual companion star, and the other to just be nearby but not orbitally bound. – The star originally thought to be a companion but no longer thought to be would be 2MASS J17405002-3052039, which is not actually in the in-game universe.

• Map Reference: GRS 1737-31
  • GRS 1737-31 is a stellar-mass black hole located in the Galactic Bar. This system was first observed in the year 1997 during observations of the galactic core, where it was detected as a source of gamma and X-rays. Today, three other stars have been found in the system; two of very hot O-class, and one hot B-class. The high mass and very similar young age of these objects suggests that they originate from a similar area. Orbital periods are also quite short, which appears to point towards either a shared origin or capture. No planets are present in this system.

Main Waypoints Details

• Map Reference: 13 Mu Sagittarii
  • While this blue-white supergiant is neither the biggest nor brightest known star in our galaxy, it is among those furthest away while still clearly visible with the naked eye from Earth. Part of the explanation for this is that the star is located deep below the galactic plane allowing for a relative clear line of sight to Earth. The other part is obviously that this IS a supergiant star with a total luminosity of 180.000 times that of the Sun. The star is the 13th star of the constellation Sagittarius (measured in apparent magnitude), and besides its designation “Mu Sagittarii” it is also known under the names Polis and Dôu. (From Galactic Mapping Project entry on EDSM page, minor edit for publishing from a 21st century perspective)
  • SIMBAD Link
  • EDSM Link
• Map Reference: HD 158320
  • HD 158320 is the furthest north known real star based system in the in-game galaxy. This is based on a search and filtering of the EDSM database ran by CMDR Waterlubber for my purposes of finding such systems. The only more northern systems in the galaxy that do not follow the Blahblah AA-A A#### naming convention are Beagle Point, VonRictofen’s Rescue, and Macedonica’s Leap, none of which are based on real celestial objects. — In real life HD 158320 is a spectroscopic binary system and member of a visial triple system. It is also a possible candidate for the X-Ray Source known as 3U 1727-33

  • AKA: SAX J1819.3-2525
  • V4641 Sagittarii is a variable X-ray binary star system in the constellation Sagittarius. It is the source of one of the fastest superluminal jets in the Milky Way galaxy. Amateur astronomer Rod Stubbings made a visual observation of a dramatic outburst during earth year 1999. This observation helped to confirm the source was a black hole with a close binary star.

  • AKA: (NBORO) Luna’s Shadow
  • Situated on the galactic prime meridian, and 1 LY above the galactic plane z-line, some 25,898 LYs from Sagittarius A* on the far side of the galaxy, this system is the physically located antithesis of Sol. Remarkably the star system also has 8 major planets, the third one being a Water World orbited by a moon that is strikingly similar in both appearance, size, and composition to that of the Earth’s moon, Luna, on the opposite side of the galaxy from this location. This moon, nicknamed Luna’s Shadow, is an ideal location for travellers to land at and collect Jumponium resources before heading out to the Abyss. (From Galactic Mapping Project entry on EDSM Page)
  • EDSM Link
• Map Reference: Beagle Point
  • AKA: (NBORO) Beagle Point
  • Beagle Point marks the end point of a galaxy-spanning expedition undertaken by Commander Kamzel in 3301. At the time, the system was known as Ceeckia ZQ-L c24-0, but Kamzel nicknamed it Beagle Point after his beloved beagle Jack, who had passed away a short time before. One year later, the system was chosen as the final destination of the first Distant Worlds expedition, resulting in an influx of over 500 pilots in April 3302. In recognition of these events, Universal Cartographics officially renamed the system Beagle Point on the 26th of May 3302. At 65,279 LYs from Sol, Beagle Point was one of the most distant star systems a commander could reach prior to the Jumponium and Engineering eras. (From EDSM System Page)

• Map Reference: Oevasy SG-Y D0
  • AKA: (NBORO) Salome’s Reach
  • This system represents a double galactic record. It is at the same time the most distant system from Sol at 65,647.34 LYs and also the system furthest north of Sol at 65,630.16 LYs. The system was apparently visited by “unknown means” sometime in 3301 by a CMDR Tooth – who originally held the first discovery tagging rights with Universal Cartographics until the system was revisited by more legitimate means by CMDR Ishum in June 3302 once engineered FSD upgrades were introduced. The system contains ‘Salomé’s Reach’ (Oevasy SG-Y D0 B 9 F). At its most extreme, this moon can be over 134,000 Light Seconds further out into the intergalactic void than the primary star is – thus making it the most distant object an explorer can currently visit. It was designated ‘Salomé’s Reach’ in honour of Senator Kahina Tijani Loren (Salomé) by the Children of Raxxla commander who was the first pilot recorded to have landed there (June 1st 3302).
