**Multimodal data** refers to data that comes in multiple formats or “modalities” for a given object. For example, an image of a galaxy is a two-dimensional array of pixel intensities, while a spectrum encodes brightness at different wavelengths, and a time series captures how the brightness of a source evolves over time. Each of these modalities offers a unique window into the physics of the source under study, which is why pairing them in a single dataset can be particularly powerful.

#### What’s in the Multimodal Universe?
3430

3531
We’ve combined publicly available data from **major astronomical surveys** into one consistently cross-matched framework, summarized in the table below. Images, spectra, hyperspectral data cubes, time-series data… they’re all in here! Each dataset has been carefully pre-processed, documented, and aligned to play nicely with one another right out of the box.
