A quantum camera can take images using light that has never actually illuminated the subject. It could be useful for imaging particularly fragile tissues and materials.

Conventional cameras capture the light that bounces off objects to create images. Consequently, dimly lit objects that are only in contact with a few light particles end up blurry. Xiaosong Ma at Nanjing University in China and his colleagues have now built a device that can utilise light that doesn’t ever touch the object. …

A Scottish photographer has managed to get some pictures of the Geminid meteor shower on its FINAL night above the UK. Amateur astronomer Graeme Whipps picked up 13 meteors on camera in the dramatic display above Pitcaple in Aberdeenshire last night (Sun). "There was a little bit of airglow, an active burst of aurora, distant lightning flashes and last, but not least, the Geminids," said Graeme, 50, who works as a meteorologist. "It wasn't as bright as the 12th and 13th but they were much more frequent, although mostly short and fast moving." The shower is an annual occurrence which happens when the Earth crosses paths with a trail of rocky debris left behind by an asteroid known as 3200 Phaethon. The debris burns up when it enters the Earth's atmosphere, giving the appearance of a "shooting star."

[ad_1] Graeme Whipps/Shutterstock I RECENTLY learned that the field of radio astronomy essentially started with a meteor shower. It was December 1945, and physicist Bernard Lovell was in Cheshire, UK, searching for cosmic rays – high-energy particles that zip through space. He had obtained a radar detector left over from the British army after the […]

[ad_1] Comet Arrokoth is a small Kuiper Belt object made of of two parts with pancake-like shapes NASA Spinning clouds of pebbles may lead to the formation of oddly flattened objects in the solar system, including comets and asteroids. In 2019, NASA’s New Horizons spacecraft flew past an icy, comet-like object beyond Pluto called Arrokoth. […]
