## Overview

The Multimodal Universe dataset is a large scale collection of multimodal astronomical data, including images, spectra, and light curves, which aims to enable research into foundation models for astrophysics and beyond.

## Quick Start

All datasets can be previewed directly from our [HuggingFace hub](https://huggingface.co/MultimodalUniverse) and accessed via `load_dataset('MultimodalUniverse/dataset_name')`! 

Preview datasets include ~1k examples from each survey.

```py

from datasets import load_dataset

dset = load_dataset('MultimodalUniverse/plasticc', 

                    split='train', streaming=True)

example = next(iter(dset))

```

You can try this out with our [getting started notebook](https://colab.research.google.com/github/MultimodalUniverse/MultimodalUniverse/blob/main/notebooks/getting_started.ipynb)!

## Data Access

To access the full dataset, we recommend downloading the data locally. This is necessary for using the provided cross-matching utilities.

The full dataset content is hosted at the Flatiron Institute and available either through HTTPS or through [GLOBUS](https://www.globus.org/):

 - https://users.flatironinstitute.org/~flanusse/MultimodalUniverse

 - https://app.globus.org/file-manager?origin_id=58a4d334-d750-454d-88a3-9d8256d091a6

GLOBUS is much preferable when downloading large amounts of data, or a large number of files. Local download of the full data in its native HDF5 format is necessary for using the provided cross-matching utilities.

After downloading the data, you can use Hugging Face's `datasets` library to load the data directly from your local copy. For example, to load the PLAsTiCC dataset:

```py

from datasets import load_dataset

dset = load_dataset('path/to/downloaded/plasticc', 

                    split='train', streaming=True)

dset = dset.with_format('numpy')

example = next(iter(dset))

```

## Architecture



Illustration of the methodology behind the Multimodal Universe. Domain scientists with expertise in a given astronomical survey provide data download and formatting scripts through Pull Requests. All datasets are then downloaded from their original source and made available as Hugging Face datasets sharing a common data schema for each modality and associated metadata. End-users can then generate any combination of subsets using provided cross-matching utilities to generate multimodal datasets.

Please see the [Design Document](https://github.com/MultimodalUniverse/MultimodalUniverse/blob/main/DESIGN.md) for more context about the project.
