Unsolved Space Mysteries

We examine the first confirmed interstellar object detected passing through our solar system, 1I/ʻOumuamua, whose peculiar acceleration and unusual physical properties sparked intense scientific debate. Our hosts analyze the detailed observational data from multiple telescopes that revealed its bizarre cigar-like shape and unexpected acceleration away from the Sun. We explore the competing theories about its composition—from hydrogen ice to ultra-thin structures—and discuss how this single object

Our hosts investigate KIC 8462852, also known as Tabby's Star, whose unprecedented irregular dimming patterns have defied conventional astronomical explanations. We examine the Kepler Space Telescope data showing light fluctuations of up to 22%, far exceeding what's typically observed during planetary transits. The discussion covers the comprehensive analysis of historical astronomical plates, modern multi-wavelength observations, and the various proposed explanations—from comet swarms to stellar

We delve into the enigmatic world of Fast Radio Bursts (FRBs), millisecond-long radio pulses from deep space that pack more energy than our Sun emits in decades. The hosts analyze the groundbreaking discovery of FRB 121102, the first repeating fast radio burst, and examine how its detection transformed our research approaches. Through detailed discussion of radio telescope data, signal patterns, and host galaxy characteristics, we explore competing theories including magnetar flares, neutron star

In this episode, we investigate the mysterious deceleration observed in the Pioneer 10 and 11 spacecraft that challenged our understanding of deep space navigation. Our hosts examine the precise tracking data that revealed an unexplained sunward acceleration of approximately 8.74 × 10−10 m/s², which couldn't be explained by known gravitational forces or spacecraft systems. We explore the decades-long investigation involving multiple research teams, the proposed theoretical explanations ranging from
