Doubling the number of known gravitational lenses

Data from the DESI (Dark Energy Spectroscopic Instrument) Legacy Imaging Surveys have revealed over 1200 new gravitational lenses, approximately doubling the number of known lenses. Discovered using machine learning trained ...

Gravitational lenses measure universe expansion

It's one of the big cosmology debates: The universe is expanding, but how fast exactly? Two available measurements yield different results. Leiden physicist David Harvey adapted an independent third measurement method using ...

Sol 2931: Mars Hand Lens Imager instrument acquires image

NASA's Mars rover Curiosity acquired this image using its Mars Hand Lens Imager (MAHLI), located on the turret at the end of the rover's robotic arm, on November 3, 2020, Sol 2931 of the Mars Science Laboratory Mission, at ...

Algae-inspired polymers light the way for enhanced night vision

In a study recently published in ACS Applied Polymer Materials, researchers from the University of Tsukuba synthesized an infrared-transmitting polymer—based on low-cost, widely available materials—that retains its shape ...

Microwave lenses harnessed for multi-beam forming

This highly compact beam forming network has been designed for multi-beam satellite payload antennas. Generating a total of 64 signal beams outputted from a single antenna, this novel design could cover the entire Earth with ...

Custom fabricated microscope lens inspired by lighthouse

An optical device that resembles a miniaturized lighthouse lens can make it easier to peer into Petri dishes and observe molecular-level details of biological processes, including cancer cell growth. Developed by KAUST, the ...
