Spacetime With Stuart Gary

SpaceTime Series 27 Episode 122*The Sun's Most Powerful Solar Flare in Over a DecadeThe Sun has unleashed its most powerful solar flare in more than a decade, with a spectacular X9.1 class event. This massive solar flare, part of a pair that erupted just two days apart, was detected by NASA’s Solar Dynamics Observatory. The event sparked strong G3 class geomagnetic storms, causing auroral activity to reach mid-latitudes and triggering deep shortwave radio blackouts. Solar flares, like this one, can have significant impacts on Earth's atmosphere, communications, and power grids.*Ceres: A Former Ocean World?New research suggests that the dwarf planet Ceres may have once been an ocean world. The study, published in Nature Astronomy, indicates that Ceres has a dirty icy crust, suggesting a past filled with muddy oceans. Computer simulations reveal that the crust may contain up to 90% ice, challenging previous assumptions of a drier Ceres. The findings are based on data from NASA’s Dawn mission, which observed sur
