  • Map Reference: NGC 752 DLM 167a
    • POI: Caldwell 28
    • Caldwell 28, also known as NGC 752 is an open cluster in the Andromeda constellation region of the sky as seen from earth. It was discovered by Caroline Herschel in 1783, and cataloged by her brother William Herschel in 1786, however an object that is now believed to be NGC 752 had also been described by Giovanni Batista Hodierna prior to 1654.
  • Map Reference: V518 Carinae
    • POI: Caldwell 102
    • Caldwell 102, also known as the Southern Pleiades is an open cluster in the Carina constellation of the sky as seen from Earth. It was discovered by Abbe Lacaille in 1751 from South Africa. It is one of the closest clusters to our solar system, being only roughly 486 light-years from our solar system. Theta Carinae (also in game) is the brightest star in the cluster.

    • POI: Caldwell 19
    • Caldwell 19, also known as The Cocoon Nebula, or IC 5146 is a reflection nebula in the Cygnus constellation area of the sky.

      Caldwell 19 is a star forming region. The most massive star known in the cluster is BD+46 3474 (doesn’t appear to be in game under any of it’s other identifiers either such as IC 5146 42, 2MASS J21532885+4715595, or ALS 12039)

      Another interesting star in Caldwell 19 is V1578 Cygni which is an example of an HAeBe Star (however in game it is A class, but that isn’t too weird as HAeBe stars eventually will become A or B class, and given Cocoon nebulae’s distance from Earth being about 2500 Ly, what we see today from Earth would be the star as it was in roughly 477 BC, and it may have become main sequence in the intervening 3,786 years between 477 BC and 3309 AD)

    • 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.

    • 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

    • POI: Kepler-186 7
    • The first Earth-sized exoplanet to be discovered within the habitable zone of its star. Represented most closely in game by Kepler-186 5. In-game it is not terraformable for whatever reason, but the criteria otherwise matches the closest. The system also contains four other known exoplanets as well represented in-game by bodies 2 (Kepler 186c), 3 (Kepler-186d), 1 (Kepler-186b), and 4 (Kepler-186e).
    • SIMBAD Link

    • Kepler-7b is the fourth of the first five exoplanets to be confirmed by the Kepler teelscope. It was the first new discovery by it as the first three were already known exoplanets used to confirm the telescope was working correctly. It is a “Hot Jupiter” orbiting close to its star and measured at a temperature of 1540K. The planet in-game representing this real exoplanet is Kepler-7 1.
    • SIMBAD Link
    • EDSM Link
  • Map Reference: CSI+19-20201

    • SIMBAD Link
    • EDSM Link
  • Map Reference: KOI 3901
    • POI: KOI 3901 5
    • This system contains a known exoplanet classified as KOI-3901.01 of roughly 40% the radius of Jupiter. (in game: KOI 3901 5 is the planet in the system matching the criteria)

      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.

      Wikipedia page about this pulsar can be found here: https://en.wikipedia.org/wiki/Black_Widow_Pulsar
    • SIMBAD Link
  • Map Reference: QZ Vulpeculae
    • 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. Do note that this system is fairly high from the galactic plane and may be difficult to reach for low jump range ships
