Failed Supernova? How a Massive Star Quietly Became a Black Hole
17/2/2026 | 33 mins.
Astronomers have identified a rare case in the Andromeda Galaxy where a massive star appears to have collapsed directly into a black hole—without exploding as a supernova. After nearly two decades of observations, researchers saw the star fade as its core imploded, while its outer layers dispersed more slowly due to internal convection.

A lingering infrared glow now marks the aftermath, offering strong evidence for models predicting “failed supernovae.” This discovery suggests that many stellar-mass black holes may form in silence, reshaping our understanding of how these cosmic objects are born.

Bennu Asteroid Samples Rewrite Origins of Prebiotic Life Molecules
16/2/2026 | 36 mins.
New analysis of asteroid Bennu shows that amino acids can form in cold, icy, and radioactive environments, overturning the idea that warm water is essential. Isotopic evidence points to multiple chemical pathways and diverse solar origins for life’s basic molecules, reshaping theories about how prebiotic chemistry emerged in the early Solar System.

First Subsurface Lava Tube Discovered on Venus
15/2/2026 | 30 mins.
Scientists analyzing NASA’s Magellan radar data have confirmed the first known subsurface lava tube on Venus, hidden beneath the planet’s thick clouds. Located near Nyx Mons, this vast volcanic tunnel may stretch for tens of kilometers, revealing how Venus’s extreme conditions shape its geology.

The discovery strengthens theories about Venusian volcanism and sets the stage for future missions like Envision and Veritas to explore the planet’s concealed interior.

Is There No Black Hole? New Dark Matter Theory at the Center of the Milky Way
14/2/2026 | 41 mins.
A new study challenges the idea that a supermassive black hole sits at the center of the Milky Way. Instead, researchers propose a dense core of fermionic dark matter that could reproduce the same gravitational effects—explaining both the fast orbits of nearby stars and the galaxy’s large-scale rotation.

The model may even account for the central shadow seen in iconic images of our galactic core. In this episode, we explore whether dark matter—not a black hole—could be the true engine shaping our galaxy.

James Webb Finds the Chemical Seeds of Life in a Distant Galaxy
13/2/2026 | 30 mins.
Using the James Webb Space Telescope, astronomers have detected a rich mix of organic molecules inside the dusty core of a distant galaxy.

The discovery includes rare hydrocarbons and the first-ever extragalactic sighting of the methyl radical, revealing these regions as powerful cosmic chemical factories.

Driven by cosmic rays, complex carbon structures are broken into smaller molecules that may act as precursors to life, offering new insight into chemical evolution hidden deep in the universe.
