Today on Astronomy Daily: Astronomers have witnessed something extraordinary in the Andromeda Galaxy — a massive star that simply vanished, collapsing into a brand-new black hole without the usual supernova fireworks. We cover the SpaceX Crew-12 launch to the ISS, Europe's powerful Ariane 64 flying for the first time with Amazon satellites aboard, another booster anomaly for ULA's Vulcan rocket, a bizarre inside-out planetary system that defies formation models, and NASA's plan to rescue the Swift observatory from orbital decay.

SpaceTime with Stuart Gary Gary - Series 29 Episode 19

In this episode of SpaceTime , we explore astonishing discoveries in astrophysics, planetary science, and aerospace engineering.

Astronomers Observe Possible Black Hole Explosion

Astronomers are investigating what could be the first ever observation of a black hole explosion. A recent study published in Physical Review Letters suggests that the mysterious high-energy neutrino detected in 2023 may have originated from a quasi-extremal primordial black hole. This type of black hole, theorized to exist since the Big Bang, could explain the otherwise unexplainable energy levels of the neutrino and potentially unlock the secrets of dark matter and the fundamental nature of the universe.

Mars' Dust Storms and Water Loss

New research published in Communications Earth and Environment reveals that localized dust storms on Mars may play a significant role in the planet's water loss. While Mars is currently a dry desert, evidence from its surface indicates a wetter past. The study shows that intense dust storms can transport water vapor to higher altitudes, facilitating its escape into space, thus contributing to the long-standing mystery of Martian water depletion.

Plasma Daniel for Hypersonic Testing

A groundbreaking facility known as the plasma tunnel is now being used by scientists and engineers to simulate the extreme conditions spacecraft face during atmospheric reentry. The plasma tunnel generates high-speed plasma flows that mimic the intense heat and pressure experienced during reentry, providing critical data for developing safer and more efficient spacecraft. This innovative technology could revolutionize our understanding of hypersonic flight and enhance mission safety for future space exploration.

Cosmic Dust in a Jar, Volcanic Eruptions on Io, and the Quest for Intelligent Life

In this exciting episode of Space Nuts , hosts Andrew Dunkley and Professor Fred Watson delve into a series of captivating cosmic stories that will spark your imagination. From the groundbreaking creation of cosmic dust in a lab to the simultaneous volcanic eruptions on Jupiter's moon Io, this episode is a treasure trove of astronomical insights.

Episode Highlights:

- Cosmic Dust in a Jar: A Sydney PhD student has synthesized cosmic dust in a laboratory setting. Andrew and Fred discuss the implications of this breakthrough for our understanding of how complex organic molecules form in space, and whether this could reduce the need for future space missions to gather samples from asteroids.

- Simultaneous Volcanic Eruptions on Io: The hosts explore the extraordinary event of five volcanoes erupting at once on Io, revealing insights into the moon’s geological activity. They discuss the gravitational forces at play and how this discovery challenges previous theories about Io's solid interior.

- Follow the Coal to Find Intelligent Life: A new theory suggests that the presence of coal may be a key factor in the development of intelligent civilizations. Andrew and Fred unpack the idea that access to natural resources could influence technological advancement, raising questions about the rarity of intelligent life in the universe.
