Hyundai’s first concept car has showcased its latest special motor, a retro coupe powered by a 500kW hydrogen fuel cell system. 0 See 13 pictures See 13 pictures Previously It Hyundai N Vision 74 The high-performance coupe concept has been revealed, providing Hyundai’s clearest indication that hydrogen fuel cells have the performance potential of a car. The N Vision 74 concept was revealed alongside the official confirmation of the Ioniq 5 N – the N brand’s first electric vehicle – and an Ioniq 6-based high-performance EV concept called the RN22e. Officially, the RN22e and N Vision 74 are ‘rolling laboratory concepts’, the vehicles Hyundai uses to test and validate future technologies. The N Vision 74 is said to provide a vision of a “hydrogen-based high-performance future” – but expect that future to look a little different, as in its current form, Hyundai has no plans to build on the concept. Its name and style pay homage to the Hyundai Pony Coupe, a 1974 concept car written by icon

Webb captures the dying star's final 'performance' in fine detail

The faint star in the center of this scene has sent rings of gas and dust for thousands of years in all directions, and NASA’s James Webb Space Telescope has revealed for the first time that the star is shrouded in dust. Two cameras aboard Webb captured the latest images of the planet’s nebula, cataloged as NGC 3132, and informally known as the Southern Ring Nebula. The distance is about 2,500 light years. Webb will allow astronomers to unearth more specifics about planetary nebulae like these—clouds of gas and dust ejected by dying stars. Understanding which molecules are present, and where they are located across shells of gas and dust will help researchers refine their knowledge of these objects. This observation shows the Southern Ring Nebula almost facing upwards, but if we could rotate it to view it from the edge, its three-dimensional shape would more clearly
