21 JAN 2026 · SpaceTime with Stuart Gary Gary - Series 29 Episode 9
In this episode of SpaceTime, we unravel the enigma of the universe's mysterious little red dots, delve into groundbreaking insights from Jupiter regarding the evolution of our solar system's planets, and mark the commencement of construction on Earth's largest gamma-ray observatory.
The Mystery of the Little Red Dots
A fascinating new study reveals that the enigmatic little red dots observed in early images from the NASA Webb Space Telescope are, in fact, young black holes cloaked in ionized gas. Researchers from the Niels Bohr Institute's Cosmic Dawn Center have determined that these black holes, much smaller than previously thought, are in the process of consuming gas, which creates immense heat and radiation, giving them their distinctive red appearance. This discovery sheds light on the formation of some of the universe's earliest black holes just 700 million years after the Big Bang.
Jupiter's Role in Planetary Evolution
New simulations indicate that Jupiter may contain up to 50% more oxygen than the Sun, providing fresh insights into how the planets in our solar system formed. By developing a comprehensive model of Jupiter's atmosphere, researchers have resolved a long-standing debate regarding the gas giant's chemical composition. The findings suggest that Jupiter's atmosphere circulates much more slowly than previously believed, which could alter our understanding of planetary migration and formation processes.
Construction of Earth's Largest Gamma-Ray Observatory
Engineers have officially begun construction on the Cherenkov Telescope Array Observatory, set to be the largest gamma-ray telescope ever built. Located in Chile's Atacama Desert, this observatory will significantly enhance our ability to study high-energy cosmic phenomena, such as black holes and supernovae. With over 60 telescopes across two sites, the observatory will allow astronomers to observe gamma rays with unprecedented accuracy, potentially unlocking new discoveries about dark matter and the fundamental laws of physics.

In this episode of SpaceTime, we explore groundbreaking discoveries in astrophysics, including the confirmation of Betelgeuse's elusive companion star, a spectacular black hole event, and the BepiColombo spacecraft's approach to Mercury.
Betelgeuse's Companion Star Confirmed
Astronomers have finally confirmed that the red supergiant star Betelgeuse has a companion star, named Saguara. Utilizing data from NASA's Hubble Space Telescope and ground-based observatories, researchers traced the influence of Saguara as it interacts with Betelgeuse's outer atmosphere. This discovery sheds light on the star's peculiar brightness variations and its eventual fate as it nears a supernova explosion, which could occur at any time in astronomical terms.
A Black Hole's Powerful Feast
In a remarkable observation, astronomers witnessed a black hole shredding a massive star in what is described as the most powerful event of its kind ever recorded. Known as a gravitational tidal disruption event, this phenomenon released energy equivalent to 400 billion times that of our Sun, surpassing even the most energetic supernovae. The event, cataloged as AT 2024WPP, offers new insights into black hole behavior and the dynamics of stellar destruction.
BepiColombo's Journey to Mercury
The BepiColombo spacecraft is nearing its orbit insertion around Mercury after a seven-year journey. Launched in 2018, this multi-spacecraft mission will study Mercury's surface, magnetic field, and interaction with solar activity. The mission consists of two orbiters that will work in tandem to gather comprehensive data about this enigmatic planet, promising to enhance our understanding of planetary formation and evolution.
