AstroLLaVA Convos: Astronomical Images with Captions and Synthetic Q&A

A large-scale collection of astronomical images paired with descriptive captions and synthetic question-answer pairs, designed for training visual language models. The dataset was created by UniverseTBD and last updated on July 28, 2025. It combines imagery from NASA's Astronomy Picture of the Day, the European Southern Observatory's public archive, and ESA's Hubble Space Telescope.

Use Cases

• Training visual question-answering models based on synthetic astronomical Q&A pairs.
• Fine-tuning image captioning models for astronomy based on descriptive captions.
• Benchmarking multimodal AI performance on domain-specific scientific imagery.
• Pre-training foundation models for astronomical visual-language understanding.

Strengths

• Combines imagery from three major astronomical sources: NASA APOD, ESO, and ESA Hubble.
• Designed as a large-scale collection specifically for training visual language models.
• Includes both descriptive captions and synthetic question-answer pairs for each image.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count, file formats, and dataset size are unknown, which may limit suitability assessment.
• The dataset's license is unknown, which may restrict usage.

Provenance

Source

NASA's Astronomy Picture of the Day (APOD), European Southern Observatory (ESO) public image archive, ESA's Hubble Space Telescope.
