Dark Energy Survey's Perplexing Discoveries Leave Astronomers Puzzled | #387

This week (Episode 387) we're chatting dark energy, megastructures, and a fateful moon landing. Andrew and Fred dive deep into some surprising discoveries that have astronomers scratching their heads. A major dark energy survey has raised more questions than answers about the nature of the cosmological constant. Then we learn about a recently discovered "big ring" - a cosmic megastructure over 10 times bigger than anything seen before! What could have created this structure? Theories abound but the experts just don't know. We also get an unfortunate update on the doomed Peregrine lunar lander. Despite valiant efforts to salvage the mission, it seems the leaking spacecraft will meet a fiery end reentering Earth's atmosphere. Such a shame, but sometimes that's just the way the cosmic cookie crumbles in this business. Hungry for more space news and insights? Well settle in and listen up as the spaced-out questions come flooding in from our stellar listeners. We cover everything from the origin of Earth's water to the possibility of terraforming Venus. Yeah there's a ton of brain food here to chew on! So click that play button and let's launch into another fun and fact-filled Space Nuts adventure! See you in the cosmos 🚀
