Welcome to Astronomy Daily, the podcast that brings you the latest news and discoveries from the cosmos. I'm Anna and I'm thrilled to be your host for today. We have a lineup of captivating stories that span from groundbreaking space missions to intriguing research discoveries. In today's episode, we'll explore China's Chang'e 6 mission, which has made history by returning with the first-ever samples from the far side of the moon. We'll also dive into NASA's successful launch of the GOES-U weather satellite, set to revolutionize real-time weather tracking. Additionally, we'll discuss a compelling study from UC Riverside on how detecting certain greenhouse gases on exoplanets could hint at extraterrestrial intelligent life. But that's not all. We'll shed light on new insights into the sun's super granules, track recent advancements in detecting spy balloons and UFOs using satellites, and delve into the fascinating world of plate tectonics on other planets. So sit back, relax, and join me on this journey through the vast and wondrous universe.00:00 Astronomy Daily brings you the latest news and discoveries from the cosmos.

Welcome to Astronomy Daily, your daily dose of celestial wonder and cosmic news. I'm Anna, your host, and I'm thrilled to take you on today's journey through the fascinating world of astronomy. In our podcast, we bring you the latest updates, expert insights, and detailed commentary on everything happening beyond our planet.

Today we've got an exciting lineup of stories that will captivate both seasoned astronomers and curious newcomers alike. We'll start with NASA's recent decision to cancel a spacewalk again due to a coolant leak. What happened, why it's significant and what it means for future missions. Then we'll dive into a busy week of launches by SpaceX and JAXA, highlighting their challenges and achievements. We'll also explore China's Chang'e-6 mission, returning with groundbreaking samples from the moon's far side. We'll examine the close approach of two large asteroids as they fly by Earth and talk about why it's crucial to enhance our detection systems. Ever wondered why some planets have moons while others don't? We'll delve into the science behind it, and later we'll uncover the mystery behind a massive aurora in the arctic sky. So sit back, relax, and let's embark on this cosmic journey together.

Join us for SpaceTime Series 27 Episode 76, where we delve into the latest groundbreaking discoveries in planetary science and astronomy.

First, scientists have uncovered evidence that fresh water existed on Earth about 4 billion years ago, pushing back the timeframe for the potential emergence of life by 500 million years. This discovery, based on zircon crystal analysis from the Jack Hills formation in Western Australia, challenges the long-held belief that Earth was entirely covered by oceans at that time. The study's findings suggest that fresh water and land masses existed much earlier, setting the stage for life to flourish.

Next, new research indicates that the rotation of Earth's inner core has slowed down compared to the planet's surface. This discovery, reported in the journal Nature, shows that the inner core began to decelerate around 2010, moving slower than the Earth's mantle and crust for the first time in decades. The implications of this change are still being explored, but it may ultimately affect the length of the day.

Finally, a new study suggests that Earth's encounter with dense interstellar clouds 2 million years ago may have significantly altered the planet's climate. The research, published in Nature Astronomy, posits that these clouds could have compressed the heliosphere, exposing Earth to increased levels of cosmic rays and altering its climatic conditions.
