Galaxies for training astroPT
Here we have ~8.5 million galaxy cutouts from the DESI legacy survey DR8.
The cut outs are 512x512 pixel jpg images centred on the galaxy source.
I've split away 1% of the images into a test set, and 1% into a validation set.
The remaining 98% of the images comprise the training set.
Metadata (galaxy properties)
There is also accompanying metadata!
To combine the metadata with the galaxy images you can do (for example):

Dataset Card for HumanTracker
Project page · Paper · Code
HumanTracker is a humanoid motion-tracking benchmark. This release contains two complementary subsets:
motions/ — the evaluation test split: retargeted 29-DoF reference trajectories, grouped into four motion families.
preference_pair/ — 6,000 human preference pairs, each stored with the two tracker rollouts that were compared and the source-motion clip they track.

Galaxy Mentions HATS
A HATS catalog of 43,546 resolved literature mentions from
astronolan/galaxy-mentions,
prepared for efficient spatial crossmatching with the
Multimodal Universe HATS catalogs.
Each row is a mention in a paper, not a deduplicated astronomical object. Multiple rows may
therefore describe the same galaxy. The optional wiki_entity_id groups mentions using the current
1 arcsecond connected-components build, while mention_id remains the unique row identifier.… See the full description on the dataset page: https://huggingface.co/datasets/astronolan/galaxy-mentions-hats.stem-reasoning-complex

1. Dataset Summary
STEM-Reasoning-Complex is a curated collection of 118.255 high-quality samples designed for Supervised Fine-Tuning (SFT) and alignment of Large Language Models. The dataset focuses on four core disciplines: Biology, Mathematics, Physics, and Chemistry.
Unlike standard QA datasets, each entry provides a structured Chain-of-Thought (CoT) reasoning process, enabling models to learn… See the full description on the dataset page: https://huggingface.co/datasets/galaxyMindAiLabs/stem-reasoning-complex.galaxy-descriptions
Galaxy Descriptions

This dataset provides galaxy cutout images, natural-language descriptions, text embeddings, and image embeddings for galaxies drawn from multiple imaging surveys (specifically Legacy DR10 and HSC PDR3 Wide).
Each row corresponds to a single galaxy and contains:
A preprocessed RGB galaxy image
A caption generated by gpt-4.1-mini
A single-sentence summary of the caption generated by gpt-4.1-nano

Galaxy metadata for pairing with `smith42/galaxies' dataset
Here we have metadata for ~8.5 million galaxies.
This metadata can be paired with galaxy jpg cutouts from the DESI legacy survey DR8,
the cut outs are found here: https://huggingface.co/datasets/Smith42/galaxies.
I've split away 1% of the metadata into a test set, and 1% into a validation set.
The remaining 98% of the metadata comprise the training set.
