In a remarkable display of the Martian atmosphere and surface features, NASA's MAVEN (Mars Atmosphere and Volatile EvolutioN) mission has unveiled stunning ultraviolet images of Mars. These captivating visuals were captured at different points along the planet's elliptical orbit around the Sun, providing scientists with...

Breakthrough in Meta-Hologram Technology Expands Possibilities for Augmented Reality

A research team at Pohang University of Science and Technology (POSTECH) has made significant strides in the field of meta-holograms, pushing the boundaries of augmented reality (AR) and virtual reality (VR) devices. Meta-holograms are artificially engineered substances, known as metamaterials, that possess extraordinary properties...

Deep UV photodetectors head to real-world testing

Numerous devices and detectors sense and catalog deep ultraviolet frequencies which the Earth's ozone layer otherwise absorbs. Most solar-blind space-borne imaging platforms still rely on photomultiplier tubes and/or microchannel plates working with silicon photodiodes that increase the systems' complexity and weight. Scientists of India asked...

Hubble snaps yet another spiral galaxy

The spiral galaxy M91 fills the frame of this Wide Field Camera 3 observation from the NASA/ESA Hubble Space Telescope. M91 lies nearly 55 million light-years from Earth in the constellation Coma Berenices. It is also evident in this image that it is a...

Sunflowers’ invisible colors help them attract bees

According to a new UBC research, the ultraviolet colours of sunflowers not only attract pollinators, but also help the plant regulate water loss. The dense collection of yellow petals of a sunflower has an ultraviolet bullseye pattern which is invisible to humans but not to...
