Revealing the Mysteries of Dark Matter, Dark Energy, and Neutron Stars | Space Nuts #345

Épisode 345

jeudi 30 mars 2023 • Durée 55:26

An all-listener questions episode. Hear what's on the minds of our listeners. Explore the mysterious universe and uncover the secrets of dark matter and dark energy with Andrew and Fred. "Matter tells space how to bend. Space tells matter how to move." - John Wheeler Professor Fred Watson is an astronomer and science communicator, best known for his work in the field of astrophysics. He is a regular contributor to numerous science-related media outlets around the globe. Professor Fred Watson was taken aback by Rusty's question about how the rotation curves vary with wavelength. After exploring Einstein's famous theory of gravity, Fred discussed the dangers of the neutron star and the web of dark matter that formed structures in the universe. He explained that dark energy, while being uniform throughout the universe, was the cause of the universe's accelerating expansion. He then discussed the possibility of dark matter black holes, concluding that they should behave the same as normal matter black holes. Finally, he discussed the research done by colleagues in Australia which suggested that the speed of light may have been different in the past. This thought-provoking conversation left Fred and the listeners with questions to ponder. In this episode, you will learn the following: 1. What phenomena would you encounter if you were magically transported to a neutron star? 2. What is the difference between dark matter and dark energy and how do they interact with each other? 3. Could the speed of light or charge of the electron have been different in the past?

The Search for Life on Venus: Uncovering Volcanic Activity | Space Nuts #344

Épisode 344

jeudi 23 mars 2023 • Durée 44:57

In this episode of the podcast, Fred Watson embarks on a journey to the National Press Club to attend a big event featuring NASA Administrator Bill Nelson, only to find himself in the wrong place at the wrong time and caught in a thunderstorm. "If you're going to bet on where the most likely place for an eruption to occur on Venus, this would be it. It's the tallest volcano on the planet." Fred Watson was in a hotel room in Canberra when a thunderstorm struck, sending him scrambling to unplug his electronics. While there, he heard about the National Press Club lunch with the NASA administrator, Bill Nelson, and his deputy, Pam Melroy. He managed to get a ticket and attended the event, where he learned about the volcanically active planet Venus. Robert Herrick, a planetary scientist at the University of Alaska, had detected a particular volcanic vent that had changed in shape and size over an eight month period. Professor Herrick suggested that this could be a recent volcanic event; and Trevor Allen's research on the carbonaceous asteroid, 162173 Ryugu, uncovered evidence of uracil, a component of RNA molecules. In this episode, you will learn the following: 1. What is the Veritas mission and how could it further our understanding of volcanoes on Venus?Herrick 2. How did researchers detect uracil in the carbonaceous asteroid 162173 Ryugu? 3. How does the sun's core lose mass and energy and how does it become visible radiation?

A Cosmic Cannibal: Uncovering the Mystery of the Loneliest Galaxy in the Universe | Space Nuts #343

Épisode 343

jeudi 16 mars 2023 • Durée 47:55

When an ambitious astrophysicist discovers a lone galaxy 9.2 billion light years away, she unravels the mystery of a fossil cluster, uncovering an unexpected twist in the evolution of carbon in the universe. In this episode, learn about astronomy topics - Quasars, Big Bang, and Carbon formation in the universe - from a conversation between Andrew and Fred about Dr. Rebecca Davis' research. They discuss how carbon started forming in the universe, which is important as we are a carbon based life form. The research found that in the early universe there was more cold carbon than warm carbon and it may be due to the first generation of stars. This research also paves the way for future investigations with the Square Kilometer Array to detect neutral hydrogen during a key phase of the universe's history. Furthermore, there is an example of extreme galactic cannibalism, with a distant galaxy called 3 C 297, which appears to be alone in space due to gobbling up all it's neighbours. "During the period when the first stars and galaxies are forming, a lot of heavy elements are forming because we never had carbon before we had stars. One possible reason for this rapid rise is just that we're seeing the products of the first generation of stars." In this episode, you will learn the following: 1. Australian astrophysicists have uncovered a crucial new development in understanding the evolution of carbon in the universe. 2. An extremely distant and old galaxy, 3C 297, is all alone in space, because it ate its friends. 3. Astronomers have discovered the earliest fossil group ever found, suggesting that galaxies gobbling up their partners and friends happened much earlier in the universe than previously thought.

Moon Time - What? | Space Nuts #342

Épisode 342

jeudi 9 mars 2023 • Durée 47:46

Hi there, thanks for joining us. This is Space Nuts. I'm your host, Andrew Dunkley. Hope you can stick around. We've got a lot to talk about today. What time is it on the moon? It's moon time.
It could be daytime, could be night-time. It depends where you are, but we're talking about real time.
We'll elaborate in this episode and offer up some solutions. There might be a new way to find Planet Nine. We're going to look at some sunrays on Mars and the dark Big Bang Theory. We'll also be answering some audience questions and much, much more on this episode of Space Nuts. "Throughout human history, exploration has actually been a key driver of improved timekeeping and geodetic reference models." The idea is how do you define time on the Moon. Do you have lots of different time zones, like we have on Earth? Or do you have a single lunar time zone? A joint international effort is now being launched towards achieving this. In this episode, you will learn the following: 1. How is time being defined on the Moon? 2. What is Planet Nine and can we find it? 3. Have Crepuscular Rays been seen on Mars for the first time?

Auroras, Spaghetti & Speed of Light: Space Nuts #341

Épisode 341

jeudi 2 mars 2023 • Durée 47:11

Experience the awe-inspiring power of the universe with a journey to see the aurora australis and witness spaghettification first-hand! Learn about Aurora displays from this Space Nuts podcast episode featuring Fred Watson and Andrew Dunkley. Apparently, people have been seeing these aurora displays in unusual places due to various plasma bubbles being spat out from the sun. This is not surprising as we are approaching the solar maximum, which is the regular up and down trend in the number of sunspots that appear on the sun. These sunspots are highly intense regions of magnetism that release energy in the form of plasma bubbles which cause the green, red and sometimes purple lights of the aurora. It is unusual for people to be seeing the aurora in places such as the UK, and the best time to look is near the equinox. Plus we’re witnessing a spaghettification first hand, but what exactly is that, and lastly, the Space Station was damaged by a micrometeoroid and a rescue mission is underway. In this episode, you will learn the following: 1. People are seeing the aurora in unexpected places - what is causing this phenomenon? 2. What will happen to the mysterious gas cloud X-7 as it passes closest to a black hole in 2036? 3. An uncrewed rescue mission was sent to the International Space Station - what was the mission and why was it necessary?
