SpaceTime with Stuart Gary Gary - Series 29 Episode 13

In this episode of SpaceTime , we uncover the hidden violent past of the Milky Way's supermassive black hole, delve into the origins of water on Jupiter's Galilean moons, and explore how meteor impacts are triggering dust avalanches on Mars.

The Violent History of Sagittarius A

For years, Sagittarius A, the supermassive black hole at the center of our galaxy, has been perceived as a quiet entity. However, new research published in the Astrophysical Journal Letters indicates that it may have experienced dramatic flares in the past. Observations from the CRISM Space Telescope reveal X-ray emissions from a gas cloud near Sagittarius A, suggesting a history of explosive activity that alters our understanding of supermassive black hole evolution and the history of our galaxy.

Water Origins of Jupiter's Galilean Moons

A groundbreaking study has determined that the contrasting water content of Jupiter's four large Galilean moons was established during their formation rather than evolving later. This research sheds light on the stark differences between Io, which is dry and volcanically active, and Europa, believed to have a subsurface ocean. The findings suggest that the primordial environment around Jupiter played a crucial role in shaping these moons' compositions.

Meteor Impacts Trigger Dust Avalanches on Mars

New evidence indicates that meteor impacts on Mars are causing dust avalanches, creating dark streaks on the planet's surface. An analysis of images from the European Space Agency's ExoMars Trace Gas Orbiter reveals that these avalanches occur primarily due to dry processes, driven by seasonal dust and wind activity, rather than water-related phenomena. This discovery enhances our understanding of Martian surface dynamics and the impact of meteor activity.

Join hosts Anna and Avery for an exciting journey through today's most compelling space stories. We explore Mercury's surprising geological activity, NASA's TESS satellite recovery, a frigid Earth-like exoplanet discovery, an accelerated ISS crew launch, runaway black holes tearing through space, and the scientific opportunities of a potential lunar asteroid impact in 2032.

### Episode Highlights

**Mercury's Hidden Activity**

New research reveals that Mercury, long considered geologically dead, is still actively losing volatile materials from its interior. Using AI analysis of 100,000 MESSENGER images, scientists have mapped 400 bright slope streaks that indicate ongoing geological processes. The BepiColombo mission will provide unprecedented new data when it arrives at Mercury.

**TESS Satellite Recovery**

NASA's planet-hunting TESS satellite recently entered safe mode after a command error caused solar panel misalignment. The spacecraft successfully recovered, demonstrating the importance of built-in safeguards. NASA is reviewing procedures to prevent future incidents.

**Ice-Cold Earth Twin**

Astronomers have discovered HD 137010 b, an Earth-like exoplanet 146 light-years away that could be as cold as minus 90°F. Despite frigid temperatures, it orbits within its star's habitable zone, offering insights into the diversity of potentially habitable worlds.

**Crew-12 Launch Advanced**

SpaceX and NASA have moved up the Crew-12 launch to February 11, four days earlier than planned, to provide relief for the three-person skeleton crew managing the ISS after the first-ever medical evacuation from the station.

**Runaway Black Holes Confirmed**

The James Webb Space Telescope has confirmed the first runaway supermassive black hole, ejected from its galaxy and leaving a 200,000 light-year trail of newborn stars. Traveling at 1,600 km/s, this discovery validates 50-year-old theoretical predictions.

**Moon Impact Opportunity**

Asteroid 2024 YR4 has a 4% chance of striking the Moon on December 22, 2032. While posing risks to satellites and Earth, such an impact would provide unprecedented scientific data on lunar geology, create spectacular meteor displays, and deliver free lunar samples to Earth.

SpaceTime with Stuart Gary Gary - Series 29 Episode 12

In this episode of SpaceTime , we uncover groundbreaking discoveries about Earth's mantle, the watery past of Mars, and the rapid growth of galaxies through cool gas filaments.

Distinct Histories of Earth’s Mantle Provinces

Recent research reveals that the two massive continent-sized regions deep within the Earth's mantle have unique chemical compositions and histories. This study challenges long-held assumptions and uses seismic wave data to illustrate how these large low velocity provinces differ in density and material, impacting the planet's heat extraction from the core and potentially affecting the stability of Earth's magnetic field.

Confirmation of Mars as a Blue Planet

New evidence from ancient Martian river deltas suggests that Mars was once covered by a vast ocean. High-resolution images reveal delta-like structures, indicating that water once flowed into an ocean approximately 3 billion years ago. This discovery supports the notion of a once habitable environment on Mars, offering insights into its geological history and the potential for life.

Galaxies Growing Through Cool Gas Filaments

A fascinating new study has demonstrated how galaxies can rapidly grow by drawing in filaments of cool gas. Observations from the Keck Telescope's Cosmic Webb Imager provide direct evidence of these gas streams spiraling into galaxies, fueling star formation at unprecedented rates. This research offers significant insights into the processes of galaxy formation and the role of the cosmic web in shaping the universe.

SpaceTime with Stuart Gary Gary - Series 29 Episode 11

In this episode of SpaceTime , we dive into the latest astronomical events, including a record-setting solar storm impacting Earth, the historic Artemis 2 mission preparing to return astronauts to the Moon, and groundbreaking evidence confirming an ancient asteroid impact in the North Sea.

Record-Breaking Solar Storm Strikes Earth

Planet Earth has recently experienced a massive geomagnetic storm triggered by an X1.9 class solar flare, followed by a coronal mass ejection. This event produced stunning auroras, visible as far north as Sydney and Brisbane. We discuss how such solar storms can affect technology on Earth and in space, including potential disruptions to communications and navigation systems, as well as the impact on satellites in low Earth orbit.

Artemis 2: A Historic Return to the Moon

NASA's Artemis 2 mission is gearing up to send astronauts back to the Moon for the first time in over 50 years. The crew will embark on a 10-day journey, orbiting the Moon and traveling further than any humans have before. We explore the mission's objectives, including testing spacecraft systems, practicing docking procedures, and conducting deep space science experiments, all while preparing for future lunar landings.

Proof of an Ancient Asteroid Impact

A decades-long debate over the origins of the Silverpit Crater in the North Sea has been resolved with new evidence confirming it was formed by an asteroid impact 43 to 46 million years ago. Utilizing seismic imaging and microscopic analysis, researchers have established this crater as a significant impact site, shedding light on the history of asteroid collisions on Earth and their implications for our planet's geological evolution.
