This addon adds some star-forming regions within the Leo Ring, a huge 650,000 light year wide ring of intergalactic gas surrounding the Leo Group of galaxies, described in https://ui.adsabs.harvard.edu/abs/2021A%26A...651A..77C/abstract . It's all estimated to be about 11 Mpc away. The addon adds se...

This addon adds SECCO 1, or at least its most massive and bright stars. SECCO 1 is a blue blob, a small intergalactic hydrogen cloud that is now undergoing starburst. These hydrogen clouds were probably stripped off a nearby galaxy as it entered the Virgo cluster, where SECCO 1 is located. SECCO 1 i...

This small addon adds the GAFO Region, a small star-forming nebula, located in the Virgo Cluster. Its projected distance from NGC 4438 is almost 60,000 light years, meaning it's basically in intergalactic space. A star cluster inside the nebula has also been detected but due to floating point errors...

Please redownload the Bug Nebula if you've already downloaded it - I uploaded a new version with the correct orientation of the nebula

Added after 3 hours 42 minutes:
Also redid the Ring Nebula - redownload that if you'd like

This addon adds the nearby Bug Nebula as well as its central star. The addon was made with Lux HMT.

I can confirm that this time the orientation of the nebula is correct

Bug

This addon adds the nearby Ring Nebula as well as its central stars. The addon was made with Lux HMT.

I don't think the orientation of the nebula ingame is exactly correct though

Ring Nebula

This addon adds almost all bright stars within the Cat's Paw Nebula, also known as NGC 6334. This addon was originally made by Lux H.M.T. and expanded on by me. The distance to the Trifid Nebula is 1750 parsecs. The addon folder's name starts in zzz so it loads last, just in case there is any other ...

This addon adds the Trifid Nebula, and its brightest stars. Once again this addon was made with Lux H.M.T. . The distance to the Trifid Nebula is 1235.7 parsecs. If you have Nussun's OB associations addon, you need to put that in a separate folder titled "ob-associations" or something, doe...

This addon adds the Eagle Nebula (as well as the Pillars of Creation), and some of its most luminous O and B-type stars. This addon was made with Lux H.M.T. . The distance to the Eagle Nebula is 1706 parsecs. If you have Nussun's OB associations addon, you need to put that in a separate folder title...

This small addon adds 7 dwarf carbon stars, which are binaries comprising of a cool main-sequence star (usually a red dwarf) and a white dwarf. The main sequence star has very high carbon content due to mass exchange with its former carbon star companion, which has since then died and become its cur...

This addon adds the distant Wolf-Rayet star WR 124, as well as its circumstellar nebula, M1-67.

M1-67


WR 124


Download (zzzzz ensures it loads last. Also, if you have my very outdated WR catalog installed, you'll need to put that in a folder with any name)

Updated Kepler-1513 - I got rid of the exomoon and added the more likely outer saturn-mass planet

Updated the Leo A addon: https://celestiaproject.space/forum/viewtopic.php?p=161976#p161976 I moved everything in Leo A due to a new distance from a paper in october. https://ui.adsabs.harvard.edu/abs/2023ApJ...959...52U/abstract I also added the stars described in that paper as well as an N-type ca...

Addon for Ursa Major III, a newly discovered Milky Way satellite: viewtopic.php?p=162351#p162351

This addon adds the newly discovered Ursa Major III, and its 11 brightest stars. Ursa Major III is incredibly small, just 19.5 light years across, and is about as bright as Altair. It's only predicted to contain a few dozen stars, and its total stellar mass is just 16 solar masses. umaiii.png UMa II...

This addon adds IRAS 12272-6240, or at least what I can infer from the paper describing it - https://arxiv.org/abs/2006.14692 IRAS 12272-6240 is a small star-forming region in the constellation of Crux, located about 30,000 light years away. It's very young and still shrouded in lots of dust. A few ...

NGC 6503 and KK 242 I'll start off with an addon for this pair of galaxies: NGC 6503, a very small spiral galaxy about as bright as the LMC, and its recently discovered dwarf satellite - KK 242 (also known as [KK98a] 242), an elongated dwarf galaxy transitioning between the irregular and elliptical...

Stars beyond the Local Group Hello everyone. This thread will serve as a repository for addons of stars and other objects outside the Local Group, the small galaxy group which we are a part of. This will mainly be for subsequent addons made by me and Nussun , but anybody is welcome to contribute. A...

AC Herculis A planetary signature around a dying post-AGB star This is the first potential planet found orbiting a post-AGB star. It's also the first potential polar circumbinary planet. I added 13 fictional moons as well (mainly for my video on the subject: https://www.youtube.com/watch?v=FfhfQ0t2...
