How you can help save Britain's rivers by becoming a citizen scientist

As part of New Scientist's Save Britain's Rivers campaign, we've rounded up the best citizen science projects that let you play an active role in improving the nation's waterways

What looks much like craggy mountains on a moonlit evening is actually the edge of a nearby, young, star-forming region NGC 3324 in the Carina Nebula. Captured in infrared light by the Near-Infrared Camera (NIRCam) on NASA???s James Webb Space Telescope, this image reveals previously obscured areas of star birth. Called the Cosmic Cliffs, the region is actually the edge of a gigantic, gaseous cavity within NGC 3324, roughly 7,600 light-years away. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image. The high-energy radiation from these stars is sculpting the nebula???s wall by slowly eroding it away. NIRCam ??? with its crisp resolution and unparalleled sensitivity ??? unveils hundreds of previously hidden stars, and even numerous background galaxies. Several prominent features in this image are described below. ??? The ???steam??? that appears to rise from the celestial ???mountains??? is actually hot, ionized gas and hot dust streaming away from the nebula due to intense, ultraviolet radiation. ??? Dramatic pillars rise above the glowing wall of gas, resisting the blistering ultraviolet radiation from the young stars. ??? Bubbles and cavities are being blown by the intense radiation and stellar winds of newborn stars. ??? Protostellar jets and outflows, which appear in gold, shoot from dust-enshrouded, nascent stars. ??? A ???blow-out??? erupts at the top-center of the ridge, spewing gas and dust into the interstellar medium. ??? An unusual ???arch??? appears, looking like a bent-over cylinder. This period of very early star formation is difficult to capture because, for an individual star, it lasts only about 50,000 to 100,000 years ??? but Webb???s extreme sensitivity and exquisite spatial resolution have chronicled this rare event. Located roughly 7,600 light-years away, NGC 3324 was first cat

We are finally closing in on the cosmic origins of the “OMG particle”

Three decades ago, we spotted the single most energetic particle ever seen, nicknamed the 'Oh-My-God particle'. Since then, we have seen many more ultra-high-energy cosmic rays – and now we are unravelling the mystery of what produces them
