Policy levers that can push decarbonisation into overdrive

Government measures to boost electric vehicle sales, the share of green ammonia in fertilizer, and public purchasing of plant proteins could help shift the decarbonisation of the global economy into high gear, researchers ...

Webb captures luminous, face-on spiral galaxy NGC 7469

Webb's picture of the month for December is dominated by NGC 7469, a luminous, face-on spiral galaxy approximately 90,000 light-years in diameter that lies roughly 220 million light-years from Earth in the constellation Pegasus.

Relativistic mirror made of plasma at kilohertz repetition rate

Scientists at the LOA (Laboratoire d'Optique Appliquée) in France succeeded for the first time to drive at a thousand shots per second a so-called plasma mirror in the relativistic regime (i.e., with a laser-field so strong ...

Webb telescope promises new age of the stars

The James Webb Space Telescope lit up 2022 with dazzling images of the early universe after the Big Bang, heralding a new era of astronomy and untold revelations about the cosmos in years to come.

NASA Webb micrometeoroid mitigation update

Micrometeoroid strikes are an unavoidable aspect of operating any spacecraft. NASA's James Webb Space Telescope was engineered to withstand continual bombardment from these dust-sized particles moving at extreme velocities, ...

Creating the world's largest SiC aspherical mirror

Aspherical components in optical systems can increase the free design variables without introducing new aberrations. That brings improved imaging quality and reduced size and weight. Aspheric components are widely used in ...
