In this video, I break down everything about the Nancy Grace Roman Space Telescope: how it captures 100x more sky than Hubble at the same resolution, why its mirror started life as a scrapped spy satellite, how it's hunting for dark matter, dark energy, and thousands of new exoplanets, and how it fits alongside Hubble and the James Webb Space Telescope. Plus, the inspiring story of Nancy Grace Roman herself — the woman who was NASA's first female executive, and the reason Hubble made it to space in the first place.

On 1,200 acres in Indiana, Amazon’s biggest AI data center is now operational, with half a million AWS Trainium2 chips entirely devoted to powering OpenAI rival Anthropic. Just over a year ago, the whole site was nothing but dirt and cornfields. Seven buildings are operating now, and once complete, the site will have around 30 buildings and consume some 2.2 gigawatts of power. CNBC went to the small town of New Carlisle, Indiana, to talk to locals who are worried about the impact on their community and electric bills - and to get a first ever on-camera tour inside what Amazon’s calling the largest cluster of non-Nvidia chips in the world. We also sat down with AWS CEO Matt Garman and Anthropic CPO Mike Krieger for more details on the partnership.
