Astronomers Release Largest Galaxy Survey, Confirming Universe Less Clumpy Than Predicted
Astronomers have released the most comprehensive cosmic map to date, confirming that matter in the Universe is less clumpy than standard cosmological theory predicts. The Dark Energy Survey observed approximately 150 million galaxies visible in Earth's southern sky, according to a Nature News report. The findings challenge existing models of the universe's structure.

Meanwhile, a new open-source framework called PageIndex has emerged, addressing challenges in retrieval-augmented generation (RAG) for handling long documents, VentureBeat reported. PageIndex aims to improve accuracy in high-stakes workflows like auditing financial statements and analyzing legal contracts, where traditional "chunk-and-embed" methods often fall short. According to VentureBeat, PageIndex achieved a 98.7% accuracy rate on documents where vector search failed.
