SpaceTime Series 28 Episode 01Webb Telescope Confirms Hubble TensionThe James Webb Space Telescope has confirmed the Hubble Tension, challenging the current understanding of cosmic theory. New observations reveal that the Universe is expanding faster now than during its early years, suggesting gaps in our understanding of cosmic physics. The study, led by Adam Rees and Thomas Barber, confirms the accuracy of Hubble's measurements, pointing to unknown factors in the Universe's expansion.
Liquid Erosion on Asteroid VestaA new hypothesis proposes that liquids could have carved out gullies on the airless asteroid Vesta. Laboratory experiments suggest that briny liquids, rather than dry debris flows, may have formed these features. This study, reported in the Planetary Science Journal, provides insights into the geological processes on Vesta.
