A mission concept to fly a solar neutrino detector close to the sun

Credit: ESA Astronomers have proposed a concept mission to fly a neutrino observatory into orbit around the sun to get a better picture of what’s going on in the sun’s core. Astronomers have very few tools to peer into the heart of the sun. Fortunately, the constant nuclear reactions taking place in the sun’s core as hydrogen combine to form helium release a relentless flood of neutrinos. Neutrinos are tiny, ghost-like particles that almost never interact with matter. On Earth we’ve built giant detectors to catch the occasional neutrino. Astronomers have used these neutrinos to understand the nuclear processes taking place inside the sun and to probe the edges of known physics. But our observatories on Earth are basically limited because our planet is so far from the sun. So what if we took the neutrino observatory into space? A te

The Hyundai N Vision 74 concept previews hydrogen's future performance

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
