NASA's SPHEREx mission won't be the first space telescope to observe hundreds of millions of stars and galaxies when it launches no later than April 2025, but it will be the first to observe them in 102 colors.

Infraredwavelength

Infrared (IR) radiation is electromagnetic radiation whose wavelength is longer than that of visible light (400-700 nm), but shorter than that of terahertz radiation (100 µm - 1 mm) and microwaves (~30,000 µm). Infrared radiation spans roughly three orders of magnitude (750 nm and 100 µm).

NASA's TBIRD (TeraByte InfraRed Delivery) demonstration and its host spacecraft—the PTD-3 (Pathfinder Technology Demonstrator-3)—have completed their technology demonstration. The TBIRD payload spent the past two years ...

Researchers at Durham University, in collaboration with international partners, have developed a robotic system that allows for continuous, long-term observation of honeybee colonies.

Patients with late-stage cancer often have to endure multiple rounds of different types of treatment, which can cause unwanted side effects and may not always help.

NASA's LCOT (Low-Cost Optical Terminal), a ground station made of modified commercial hardware, has transmitted its first laser communications uplink to the TBIRD (TeraByte Infrared Delivery), a tissue box-sized payload formerly ...

When it rains heavily, plastic waste is washed off our streets into rivers, flowing out to the ocean. Most plastic is trapped in estuaries and coastal ecosystems, with a small fraction ending up offshore in the high seas.

near-infraredlight

Direct sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux, which includes infrared (47% share of the spectrum), visible (46%), and ultra-violet (only 6%) light. Bright sunlight provides luminance of approximately 100,000 candela per square meter at the Earth's surface.

Observing our planet from the International Space Station since July 2022, NASA's EMIT (Earth Surface Mineral Dust Source Investigation) mission is beginning its next act.

New observations from the James Webb Space Telescope (JWST) have confirmed a decades-old galaxy model, originally proposed by a University of Portsmouth Professor in 2005.

In the fight against antibiotic resistance, a new technology developed at Chalmers University of Technology, in Sweden, can be of great importance when, for example, hip and knee implants are surgically inserted. By heating ...
