James Webb Telescope Finds Most Distant Known Galaxy

Handout infrared image from NASA’s James Webb Space Telescope (also called Webb or JWST) was taken by the NIRCam (Near-Infrared Camera) for the JWST Advanced Deep Extragalactic Survey, or JADES, program. The NIRCam data was used to determine which galaxies to study further with spectroscopic observations. One such galaxy, JADES-GS-z14-0 (shown in the pullout), was determined to be at a redshift of 14.32 (+0.08/-0.20), making it the current record-holder for the most distant known galaxy. This corresponds to a time less than 300 million years after the big bang. In the background image, blue represents light at 0.9, 1.15, and 1.5 microns (filters F090W + F115W + F150W), green is 2.0 and 2.77 microns (F200W + F277W), and red is 3.56, 4.1, and 4.44 microns (F356W + F410M + F444W). The pullout image shows light at 0.9 and 1.15 microns (F090W + F115W) as blue, 1.5 and 2.0 microns (F150W + F200W) as green, and 2.77 microns (F277W) as red. Photo by Nasa via ABACAPRESS.COM

Saturn Captured By James Webb Space Telescope

Saturn Captured By James Webb Space Telescope

This image shows Saturn and some of its moons, captured by the James Webb Space Telescope’s (JWST) NIRCam instrument on June 25, 2023. In this monochrome image, NIRCam filter F323N (3.23 microns) was color mapped with an orange hue. JWST turned to the ringed world Saturn in June 2023 to conduct a deep search for new ring structure and faint moons. Saturn itself appears to extremely dark at the infrared wavelengths sensed by JWST’s Near-Infrared Camera (NIRCam), as methane gas absorbs almost all of the sunlight falling on the atmosphere. However, the icy rings stay relatively bright, leading to the unusual appearance of Saturn in the JWST image. Several very deep Saturn exposures taken together with this image were designed to test JWST’s capacity to detect faint moons around the planet and its bright rings. Any newly discovered moons would be important dynamical tracers of the current Saturn system as well as its past history. This context image clearly shows details within the ring system, along with many of

Air pollution continues in Beijing

BEIJING, China - A woman wears a mask as she walks in China's capital on Jan. 5, 2015, although the Beijing Municipal Environmental Protection Bureau unveiled the previous day that levels of PM2.5, airborne particles smaller than 2.5 microns in diameter and a major air pollutant, declined in 2014 by 4 percent from 2013.

Fish found off Mumbai coast may contain microplastics

STORY: Fish found off Mumbai coast may contain microplastics DATELINE: March 11, 2022 LENGTH: 00:02:25 LOCATION: MUMBAI, India CATEGORY: ENVIRONMENT SHOTLIST: 1. various of the Mumbai beach 2. SOUNDBITE (Hindi): CHETAN KOLI, Fisherman STORYLINE: The Central Institute of Fisheries Education (CIFE) in India has found an abundant variety of microplastics in the gastrointestinal (GI) tracts and gills of croaker fish netted off Mumbai's coast. The research, based on a survey done along Mumbai's coastline, was recently published in the renowned Elsevier journal. It found that the GI tract and the gills of the fish had microplastics less than 100 microns in size. The study had sought to establish the intensity of microplastic pollution in demersal species or bottom-feeders found in the northeastern coastal waters of the Arabian Sea. The microplastics found in the fish tissue were predominantly black and blue in color and posed a carcinogenic risk to consumers and organisms in the food chain. Reacting to the

Japanese Environment Minister Yoshio Mochizuki (L) talks with his Chinese counterpart Chen Jining in Shanghai on April 29, 2015, the first such ministerial meeting in about three years. At the meeting, held on the sidelines of a trilateral meeting involving South Korea, they agreed to jointly tackle the prevention of high levels of the pollutant PM2.5 -- harmful particles in the air with a diameter of less than 2.5 microns.
