Universe's Expansion May Be Slowing: New research challenges the long-held belief that the universe's expansion is accelerating due to dark energy. This study suggests that dark energy might be evolving and weakening over time, potentially leading to a scenario where gravity could eventually dominate, resulting in a Big Crunch.
Tianwen 1's Interstellar Photography: China's Tianwen 1 orbiter has captured stunning images of the interstellar object 3I Atlas, marking a significant achievement in its extended mission phase. These observations provide crucial insights into the object's composition and offer practice for future sample return missions.
Launch Scrub Update: The much-anticipated launch of United Launch Alliance's Atlas V rocket carrying the Viasat 3F2 satellite was scrubbed due to ground systems equipment issues. The launch has been rescheduled, with hopes for a successful liftoff soon, as this satellite is crucial for global broadband coverage.
Mysterious Black Hole Flare: A supermassive black hole has emitted an unprecedentedly long-lasting flare, observed by the Zwicky Transient Facility. This unusual event raises questions as it defies typical flare durations, hinting at the consumption of an exceptionally massive star.
Alien Probes in Our Solar System? A recent scientific paper explores the concept of von Neumann probes—self-replicating robotic explorers that could potentially be in our solar system. The authors suggest searching for technosignatures on the Moon, where artifacts could remain undisturbed for millions of years.

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
