SpaceTime Series 29 Episode 81How a passing star redirected comets to the inner solar systemA fascinating new study reveals how a passing star, HD 7977, may have altered the trajectory of comets from the Oort Cloud, sending them cascading into the inner solar system. This event, which occurred approximately 2.47 billion years ago, could still be influencing comet activity today. Researchers used data from the European Space Agency's Gaia mission to refine the distances involved and suggest that the gravitational perturbations from HD 7977 temporarily dominated the generation of new comets.Changing our map of the Milky Way GalaxyAstronomers have redrawn the map of our Milky Way galaxy, moving its outer arms up to 10% further away than previously estimated. This revised picture is based on observations of gamma-ray bursts and the subsequent echoes of X-rays that helped to measure distances within the galaxy. New techniques have allowed for a clearer understanding of the Milky Way's structure, confirming the existence of its four spiral arms.Evidence of vast hidden magma systems inside MarsNew findings suggest that Mars once hosted extensive magmatic systems beneath its surface, despite the absence of plate tectonics. Data from NASA's InSight mission has revealed a previously unidentified boundary layer deep within the Martian crust, indicating complex geological processes that may have allowed the Red Planet to develop a habitable environment. This challenges long-held assumptions about the geological capabilities of rocky planets without tectonic activity.The Science RobertA new study indicates that the mental health of high school peers can significantly affect individual mental health outcomes. Additionally, research finds no link between paracetamol use during pregnancy and the risk of autism or ADHD. A detailed analysis of a fossilised pterosaur wing reveals insights into its diet, while scientists discover new methods to control quantum light sources, bringing us closer to practical quantum technologies.1.
