 That’s why we’re excited to have partnered with the **Multimodal Universe** collaboration to introduce a new, large-scale curated collection of standardized data designed to accelerate ML research in astronomy. If you’ve ever dreamed of having a unified resource that seamlessly ties together images, spectra, time-series, and more, from multiple surveys, we built the Multimodal Universe with you in mind.

 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.
