#407-408 Premium: Cosmic Conundrums & Volcanic Ventures: Unraveling the Universe's Expansion & Mars' Hidden Fire Mountain

Prepare to have your mind expanded to the farthest reaches of the cosmos in this mind-boggling episode of Space Nuts. Andrew Dunkley, your host, and the ever-enlightening Professor Fred Watson are here to unravel the mysteries of the universe's expansion speed and to reveal a colossal discovery that's been hiding on the Red Planet. First, we dive into the cosmic conundrum that's been baffling astronomers: the expansion speed of the universe. With new data from the James Webb Space Telescope affirming previous Hubble Space Telescope findings, we're left with two conflicting speeds of cosmic expansion. The debate heats up as we explore the possibility of unknown physics at play in the vast expanse of space. Could we be on the brink of a breakthrough that reshapes our understanding of the cosmos? Next, we set our sights on Mars, where a giant volcano has been discovered. Not just any volcano, but one that's been hiding in plain sight. This behemoth, now known as the Noctis Volcano, stands over 9,000 meters tall and stretches 450 kilometers in diameter. Join us as we discuss the potential of this Martian marvel for future exploration and the intriguing evidence of ancient glacial ice hidden beneath its surface. From the perplexing pace of universal expansion to Martian volcanic giants, this episode is a cosmic journey like no other. So, strap in and join us as we explore these celestial revelations.
