We are finally closing in on the cosmic origins of the 鈥淥MG particle鈥�

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 鈥� and now we are unravelling the mystery of what produces them

Majestic photographs of the world’s major telescopes

Researchers at SLAC National Accelerator Laboratory are nearly done with the LSST Camera, the world's largest digital camera ever built for astronomy. Roughly the size of a small car and weighing in at three tons, the camera features a five-foot wide front lens and a 3,200 megapixel sensor that will be cooled to -100??C to reduce noise. Once complete and in place atop the Vera C. Rubin Observatory's Simonyi Survey Telescope in Chile, the camera will survey the southern night sky for a decade, creating a trove of data that scientists will pore over to better understand some of the universe's biggest mysteries, including the nature of dark energy and dark matter.

Planet-sized telescopes could be possible using quantum technique

While the purpose of this image was to focus on the bright star at the center for alignment evaluation, Webb's optics and NIRCam are so sensitive that the galaxies and stars seen in the background show up. At this stage of Webb?s mirror alignment, known as ?fine phasing,? each of the primary mirror segments have been adjusted to produce one unified image of the same star using only the NIRCam instrument. This image of the star, which is called 2MASS J17554042+6551277, uses a red filter to optimize visual contrast.

James Webb Space Telescope just sent back its first image – of itself

News
James Webb Space Telescope fired its onboard thrusters for nearly five minutes (297 seconds) to complete the final post launch course correction to Webb?s trajectory. This mid-course correction burn inserted Webb toward its final orbit around the second Sun-Earth Lagrange point, or L2, nearly 1.5 million kilometres away from Earth.
