Ius and Tithonium Chasmata on Mars. This image from ESA’s Mars Express shows Ius and Tithonium Chasmata, which are part of the canyon structure of Mars’ Valles Marineris. This image consists of data collected by the Mars Express High Resolution Stereo Camera (HRSC) on April 21, 2022.

This is a dusty, cold, desert world with a very thin atmosphere. Iron oxide is abundant on the surface of Mars, giving it its reddish color and its nickname "Red Planet." The name Mars comes from the Roman god of war. ” data-gt-translate-attributes=”[{” attribute=””>Mars Express’s latest image release takes us over two ruptures in the martian crust that form part of the mighty Valles Marineris canyon system. Valles Marineris cuts across Mars similar to how the Grand Canyon cuts across the United States, except the latter is tiny in comparison. At

A Victorian perfumer has summed up the smell of Melbourne’s traffic after being challenged by ABC Radio Melbourne to stop its rush hour activity. Perfume Janelle Donnelly was asked to create the scent, named Eau D’ometer, after talking to a radio station about some of the city’s commuter scents. Donnelly says that he likes to go overboard, but he’s never been asked to limit the essence of traffic. “I think one of our favorite things as perfumers … is taking really left-handed concepts and turning them into fragrances,” she says. Janelle Donnelly told an outside broadcast how she created the scent. ( ABC Radio Melbourne: Zilla Gordon ) He hopes the finished product encapsulates “tears stuck in Melbourne traffic”. “We added a little more black pepper to give it that intensity, so it would be sharper and have more of a grating effect,” says Donnelly. The fragrance is built on geosmin, which gives the product an earthy scent that results after a rain, often referred to as petrichor. “A d

Gemini South, one of the most productive and powerful infrared-optical telescopes in the world, received a major capability upgrade with the successful installation of a new high-resolution spectrograph called GHOST built by an international consortium. This cutting-edge scientific instrument will expand our understanding of the earliest stars, the chemical fingerprints of distant planetary systems, and the formation and evolution of galaxies. Gemini South in Chile is half of the Gemini International Observatory, operated by NOIRLab NSF. The latest scientific instrument from the Gemini South telescope — GHOST, Gemini High-resolution Optical SpecTrograph — achieved its first light by making excellent observations of HD 222925, a very bright and chemically complex star located more than 1,400 light-years to the south. hemisphere of the constellation Tucana. This star is a prime example of the type of object GHOST will investigate. Gemini South is half of the Gemini International Obs

by Jeremy Gray posted Friday, July 15, 2022 at 15:00 EDT Yesterday, we saw Webb’s incredible photos of the Southern Ring Nebula. On Wednesday, the focus was Webb’s first deep-plane image of SMACS 0723, the sharpest and deepest image of the universe captured so far. Now it’s time to take a look at Stephan’s Quintet, as imaged by the Webb Near Infrared Camera (NIRCam) and Central Infrared Instrument (MIRI). The Quintet Stephan image is a large mosaic of nearly 1,000 images. This is Webb’s big image to date and contains over 150 million pixels. You can download the full 150MB .TIFF file here. All of these details allowed researchers to investigate how interactions between galaxies drove the evolution of galaxies in the early universe. Stephan’s Quintet (NIRCam and MIRI composite image). “With its powerful infrared vision and extremely high spatial resolution, Webb demonstrates never-before-seen detail in this galaxy cluster. Sparkling clusters of millions of young stars and stellar-b

The faint star in the center of this scene has sent rings of gas and dust for thousands of years in all directions, and NASA’s James Webb Space Telescope has revealed for the first time that the star is shrouded in dust. Two cameras aboard Webb captured the latest images of the planet’s nebula, cataloged as NGC 3132, and informally known as the Southern Ring Nebula. The distance is about 2,500 light years. Webb will allow astronomers to unearth more specifics about planetary nebulae like these—clouds of gas and dust ejected by dying stars. Understanding which molecules are present, and where they are located across shells of gas and dust will help researchers refine their knowledge of these objects. This observation shows the Southern Ring Nebula almost facing upwards, but if we could rotate it to view it from the edge, its three-dimensional shape would more clearly
