The Hubble Tension: Could Primordial Magnetic Fields Explain the Expanding Universe?
19/2/2026 | 32 min
Astronomers are grappling with the Hubble tension—a major conflict in measurements of how fast the universe is expanding.

Data from the cosmic microwave background point to a slower rate, while supernova observations suggest a faster one. New research proposes that primordial magnetic fields from the early universe may have influenced hydrogen formation and altered cosmic expansion.

Recent simulations indicate these ancient magnetic effects could help reconcile the discrepancy, offering fresh insight into the physics of the infant universe and the origins of cosmic structure.

Black Hole Binaries Revealed by Gravitational Lensing
18/2/2026 | 32 min
Astronomers have proposed a new way to detect supermassive black hole binaries—by watching how they bend and magnify starlight. As two black holes orbit each other, their combined gravity acts as a rotating gravitational lens, producing predictable, repeating flashes from distant background stars.

These light signals could reveal the pair’s masses and orbital motion long before they merge. Using wide-field sky surveys, researchers aim to turn black holes into natural telescopes, opening a new window into the evolution of the universe’s most powerful duos.

Failed Supernova? How a Massive Star Quietly Became a Black Hole
17/2/2026 | 33 min
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 min
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 min
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.
