NOIRLab Releases High-Resolution Images of 88 Constellations and Colossal Photo of Night Sky
NSF’s NOIRLab, in collaboration with ESA/Hubble, has released a collection of free, high resolution images of all 88 constellations and the largest open-source, freely available all-sky photo of the night sky. This all-sky photo of the night sky was compiled using images taken by astrophotographer Eckhard Slawik from the best and darkest locations around the
Nanostructured Filaments Produce Bright Light Waves that Twirl as They Travel
Bright, twisted light can be produced thanks to nanostructured filaments with twisted geometry, according to scientists at the University of Michigan. Planck’s law ignores but does not prohibit black-body radiation (BBR) from being circularly polarized. BBR from nanostructured filaments with twisted geometry from nanocarbon or metal has strong ellipticity from 500 to 3000 nanometers. The
Leopards Can Be Identified by Their Vocalizations, New Study Shows
Conservation requires accurate information about species occupancy, populations and behavior. However, gathering these data for elusive, solitary species, such as leopards (Panthera pardus), is often challenging. In a large-scale paired camera trap and autonomous recording survey in Nyerere National Park, Tanzania, scientists found that each leopard has its own unique roar through which it can
New Species of Herbivorous Dinosaur Discovered in China
Dubbed Archaeocursor asiaticus, the newly-discovered species is the earliest-diverging ornithischian dinosaur yet discovered in Asia, according to a team of paleontologists from China. Archaeocursor asiaticus. Image credit: Yao et al., doi: 10.1016/j.isci.2024.111641. Archaeocursor asiaticus lived in what is now southwestern China during the Early Jurassic, some 193 million years ago. This dinosaur was around 1
Study: Pre-Roman Copper Industry in Timna Valley Had No Polluting Impact on Environment
Scientists from Tel Aviv University have conducted geochemical surveys at two smelting camps — dating back to the 10th century BCE, the era of the Biblical Kings David and Solomon — in Timna Valley in the Southern Arabah, southern Israel. They’ve found that the environmental pollution resulting from copper production was minimal and spatially restricted
