  • Map Reference: NGC 188 SMV 4385
    • POI: Caldwell 1
    • Caldwell 1, also known as NGC 188 is an open cluster located within the Cepheus constellation areas of the sky as seen from Earth. Being circumpolar as well it is always above the Horizon no matter where you are in the northern hemisphere. It was discovered in 1831 by John Herschel. Among open clusters it has a high number of main sequence stars making it of particular interest to scientists studying those and for potential exoplanets.

      It is the first object in the Caldwell catalog made by Sir Patrick Alfred Caldwell-Moore to act as a complement to the Messier catalog. The objects in the Caldwell catalog are ordered by their declination, meaning Caldwell 1 is the most northerly in the sky, and Caldwell 109 being the most southerly.

Optional Waypoints

The optional waypoints for this leg is to simply scout out any stars you can within the cluster. There is a shared discoveries spreadsheet available at this link: https://1drv.ms/x/s!AuaQ1lvTHzu7jkpyRmG-FXzQ2uvU?e=dE7SG0 to keep track of what has already been scouted by the group and what needs to be scouted still. Please make sure to record any progress there as well!

CEA 5 Leg 1

We are setting off with the first leg of the fifth Celebration of Early Astronomy. In this leg we are travelling from the human populated bubble up to our entry basecamp for Caldwell 1, which we will then enter on leg 2 and spend three weeks scouting in depth.

    • POI: Caldwell 41
    • Caldwell 41, The Hyades Cluster is the nearest open cluster to our own solar system, and one of the best studied star clusters in existence due to that. From the perspective of Earth, it appears within the constellation Taurus at a similar angle in the sky to Aldebaran, albeit unrelated to Aldebaran otherwise. Four stars of the Hyades, with Tauri constellation Bayer designations Gamma, Delta 1, Epsilon, and Theta form the asterism that is the head of Taurus the Bull. Due to its proximity to our own solar system, the distance to it can be measured using parallax shift of the member stars as we orbit our own sun throughout our year. This leads to the a highly accurate mesaurement of roughly 145 Ly to the center of the cluster. 45 Tauri particularly is on the closer side of the cluster.

“The early 2000s, they were often the speculative setting of early science fiction works. Early imaginings of interstellar travel, first contact with aliens, apocalypses, pandemics, you name it, there was probably a movie or book set in the early 21st century of it. While humanity may not have invented interstellar travel by 2020 as many novels and films purported, they still discovered plenty gems of our galaxy by then.

Lucky for us in 3308 we do have interstellar travel and can visit these gems that humans on Earth in the early 21st century could only dream of visiting. So that is just what we will be setting out to do. This expedition will visit many of the noteworthy celestial objects discovered by the early 21st century, some of which even still are considered noteworthy even today in 3308.

We will be setting off from our faction’s home system Keltim, also known as Gliese 149 to the humans of 2020. From there we will be travelling our route clockwise. Many of the sights on this expedition revisit those featured on earlier CEA expeditions for those that weren’t on those.

For Celebration of Early Astronomy 5 we are focusing on exploring various Caldwell clusters, and in particular, Caldwell 1, a large cluster high up from the galactic plane that can only be entered and exited using a carrier. The Caldwell catalog was created by Sir Patrick Alfred Caldwell-Moore, a British astronomer and influential TV presenter on the topic of astronomy.

All legs will be one week long with the exception of our week in Caldwell 1, which will be three weeks long in duration. During this time there will be a pair of carriers swapping positions daily

      Of interest to the At the Eldritch Gate expedition in particular is that the planet in question is a gas giant with Ammonia based life, which have the chance to be a green gas giant, so may actually be our giant. Or maybe not, but at the very least it’s an interesting real world planet.
    • SIMBAD Link
  • Map Reference: PSR J1959+2048
    • POI: Black Widow Pulsar
    • Nicknamed “The Black Widow Pulsar”, PSR B1957+20 aka PSR J1959+2048 is an eclipsing binary millisecond pulsar discovered in 1988 by the Arecibo radio telescope with a rotation period of 1.6ms. It orbits with a companion super-jupiter brown dwarf with orbital period of 9.2 hours when it was discovered. At discovery it was hypothesised that the brown dwarf companion was being destroyed by the powerful outflow of high energy particles from the neutron star’s jet cones. As it is no longer there in 3308 this seems to have held true. It was the first known pulsar with this arrangement and is the namesake of the class of pulars known as spider pulsars. Black widow types having a companion brown dwarf, and redback types having companion red dwarfs.

      This pulsar was also observed by the XMM-Newton telescope to observe it’s Intra-binary Shock, scientific paper can be found here: https://iopscience.iop.org/article/10.3847/2041-8213/ac15f7/pdf

      Chandra X-Ray Telescope has also determined through observations of the system’s bow shock that is has a high speed across the galactic plane in comparison to most stars. Approximately 20 times as fast as our own solar system.

    • Discovered by the Ginga telescope in April 1988 when it produced an X-ray nova caused by matter falling in from it’s K class companion into the black hole classified as GS 2000+25. In 3308 it is found to also contain some other bodies, including a terrestrial planet with ammonia based life.
  • Map Reference: Campbell’s Hydrogen Star
    • First discovered by William Wallace Campbell who noted it’s peculiar hydrogen-rich spectra. It was an at the time uncharted planetary nebula, and a member of the yet to be classified WC subclass of Wolf-Rayet stars.

Map Reference: HD 175876

AKA: Heaven’s Lathe

The bright O-type star HD 175876 has a companion neutron-star with a surprising feature: Extremely large rings. The effective radius of the rings are 12 light seconds, and it has a mass of 5.16 x 10^17 kg – slightly greater than Thebe, a small moon of Jupiter. As the neutron star has a radius on the order of 10km, this object has an exceptionally large ring size relative to the central body. These massive metal-rich rings would provide enough material for hundreds of years for any colony.

Map Reference: PSR J1300+1240

POI: Lich, and exoplanets

Where the first extrasolar planets were discovered in 1992. It is a millisecond pulsar with a rotation period of a mere 6.22 milliseconds (9,650 rpm), but was found to have slight anomalies in its rotational period, leading to investigations as to the cause of that. Those investigation led to the confirmation of the first planets found outside of our own solar system. In 1994 an additional planet was also found in orbit of this pulsar.

Too far to be reachable by most ships, is an optional waypoint as a result

Route to: This route was found by CMDR Merlinsan during this expedition and has been edited into this post, start at HD 112186.

Map Reference: Sol

First discovered in 450 BC by Anaxagoras, Sol is a G-class main sequence star of exactly 1 solar mass and 1 solar radii. It also hosts a mostly harmless Earth-like world “Earth” as its third planets, containing sentient lifeforms known as humans. (although their sentience is sometimes questionable)

What we mean by discovered in 450 BC by Anaxagoras is that this they were first to propose that our Sun may be a star like the other ones in the sky. It was later again suggested by Aristarchus of Samos, but did not catch on until later on still.

Other important first discoveries in this system:

Note that you may need Jumponium for this.
  • SIMBAD Link
  • Map Reference: Hypoae Ain MO-I D9-37
    • POI: Heart & Soul Nebulae
    • This is a pair of nebulae very close to each other. First is the Heart Nebula, aka IC 1805. An emission nebula in the Persues Arm of the Mily Way, and in the Cossiopeia constellation of the sky. Within the nebula is a bright open cluster of stars known as Collinder 26 and contains a few bright stars nearly 50 times the mass of our sun, as well as many more dim stars. The size of the nebula in the night sky is nearly 2 degrees of arc, making it nearly four times the size in the night sky as the full moon.

      The second nebula is the Soul Nebula, also known as Westerhout 5. It is also an emission nebula like the Heart Nebula. Near the nebula in the night sky can also be seen the galaxies Maffei 1 and Maffei 2 of the Maffei Group. Soul Nebula is one of the most studied nebula in the field of star formation, due to it’s angle to us and ease of seeing the gas cavities and stellar formation areas allowing sceintists to easily see how gas cavities formed from the stellar winds of a star’s birth compress gasses together from other cavities leading to a chain reaction of stellar formation.

  • Map Reference: Bubble Sector LX-T B3-1
    • POI: Bubble Nebula
    • The Bubble Nebula, also known as NGC 7635 is an emission nebula in the Cassiopeia region of the sky. It is formed from stellar wind from the central star BD+60 2522. (For whatever reason however in the in-game galaxy it placed that star nearly 5,000 Ly away from the bubble nebula)

      While BD+60 2522 is around two million years old, the Bubble Nebula is only about 40,000 years old. It is hypothesised that the bubble formed as a shock front where stellar wind meets interstellar material at supersonic speeds as the wind from the star travels outwards at between 1,800 to 2,500 kilometers per second.

Three of which were within the habitable zone of this ultra-cool red dwarf star roughly 39.5 light years from Earth. Players of Elite: Dangerous quickly realized that there was a system in roughly the correct location called Core Sys Sector XU-P A5-0 at 42 Ly from Sol that happened to be a brown dwarf, not much colder than the red dwarf named Trappist-1 with seven terrestrial worlds around it. The system was officially tweaked to be a red dwarf and renamed to Trappist-1 for the 2.3 update.

    • 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.

    • 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.

    • AKA: OGLE-2005-BLG-071Lb
    • OGLE-2005-BLG-071Lb is an exoplanet discovered by the Optical Gravitational Lensing Experiment in 2005 using gravitational microlensing. It is believed to have about 3.5 times the mass of Jupiter and orbit roughly 3.6 AU from the star. However another model predicts a slightly lower mass of 3.3 times Jupiter mass and an orbit of 2.1 AU and is considered only slightly less likely of a match.

  • Map Reference: Shapley 1
    • POI: Fine Ring Nebula
    • Shapley 1 was discovered in 1936 by Harlow Shapley, it is an annular planetary nebula viewed from Earth almost perfectly perpindicular. In reality it is determined that the central star is a white dwarf, however in-game it is represented by a Wolf-Rayet. This may be due to new data since the in-game galaxy was created.
  • Map Reference: Antares
    • The 15th brightest star in the night sky and the brightest star in the Scorpius constellation. It is often referred to as The Heart of the Scorpion because of its distinct red hue when viewed with the naked eye.

      It is a red supergiant and among the largest known stars. It also has a companion star Antares B which is a typical B-class star
    • Note: Previously this system would jump you into the “B” star for whatever reason. Not sure if this is still the case in Odyssey.

Main Waypoints Details

  • Map Reference: Sagittarius A*
    • Sagittarius A* is the Supermassive Black Hole at the center of the Milky Way Galaxy, the type of black hole generally accepted to be at the center of most, if not all spiral and elliptical galaxies. Observations of stars, most notably S2 that orbit around Sagittarius A* have been used to show the presence of a supermassive black hole at that location. S2’s highly eccentric orbit and proximity to Sagittarius A* has been instrumental for scientists use in determining the location and mass of Sagittarius A. At it’s closest to Sagittarius A S2 was recorded to travel at a speed of 7650 km/s, or 2.55% the speed of light.

  • Map Reference: Great Annihilator
    • Large black hole pair in the galactic center, one of the brightest gamma ray sources found in the Milky Way, producing massive amounts of photon pairs at 511 keV, which usually indicates the annihilation of an electron-positron pair. Additionally it emits high-velocity synchrotron radiation in the radio spectrum for an estimated three lightyears from it.

    • POI: (NBORO) Black Hole Only Nebula
    • 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.
