NASA releases next wave of images from James Webb Space Telescope
Tuesday, 12 July 2022 14:52The James Webb Space Telescope began releasing a new wave of cosmic images on Tuesday, heralding a new era of astronomy. "Every image is a new discovery," said NASA administrator Bill Nelson. "Each will give humanity a view of the universe that we've never seen before." On Monday, Webb revealed the clearest image to date of the early universe, going back 13 billion years. One new ima
Webb Telescope is now fully ready for science
Tuesday, 12 July 2022 14:52The months-long process of preparing NASA's James Webb Space Telescope for science is now complete. All of the seventeen ways or 'modes' to operate Webb's scientific instruments have now been checked out, which means that Webb has completed its commissioning activities and is ready to begin full scientific operations. Each of Webb's four scientific instruments has multiple modes of operati
AFRL spacecraft recurve launches on Virgin Orbit Space Force mission
Tuesday, 12 July 2022 14:52The Air Force Research Laboratory Space Vehicles Directorate spaceflight experiment Recurve was launched July 2, 2022, from the Mojave Air and Space Port on the Virgin Orbit space system in California. The launch supported the U.S. Space Force's STP-S28A mission and carried six additional payloads for the Department of Defense Space Test Program (STP). Recurve is the latest in several low-
Chinese scientists help solve riddle of Moon's largest crater
Tuesday, 12 July 2022 14:52Chinese scientists have published a study that helps to explain an anomaly in the composition of the Moon's biggest crater - the South Pole-Aitken Basin - identifying the abnormal materials there as originating from the lunar crust. The study was conducted by a Chinese research team studying planetary sciences at Shandong University, and was published in the Astrophysical Journal Letters.
Virgin Galactic picks Boeing subsidiary to build two motherships
Tuesday, 12 July 2022 14:52Space travel company Virgin Galactic on Wednesday said it had reached an agreement with Boeing subsidiary Aurora Flight Sciences to build two new air launch carrier aircraft for its spaceships. These new "motherships" will replace Virgin Galactic's existing carrier plane - the VMS Eve built by Scaled Composites - with the first of the new aircraft due to enter service by 2025. The company
Upside-down design expands wide-spectrum super-camera abilities
Tuesday, 12 July 2022 14:52By turning a traditional lab-based fabrication process upside down, researchers at Duke University have greatly expanded the abilities of light-manipulating metasurfaces while also making them much more robust against the elements. The combination could allow these quickly maturing devices to be used in a wide range of practical applications, such as cameras that capture images in a broad
Webb reveals cosmic cliffs, glittering landscape of star birth
Tuesday, 12 July 2022 14:34This landscape of "mountains" and "valleys" speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA's new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth.
Called the Cosmic Cliffs, Webb's seemingly three-dimensional picture looks like craggy mountains on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within NGC 3324, and the tallest "peaks" in this image are about 7 light-years high. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image.
The blistering, ultraviolet radiation from the young stars is sculpting the nebula's wall by slowly eroding it away. Dramatic pillars tower above the glowing wall of gas, resisting this radiation. The "steam" that appears to rise from the celestial "mountains" is actually hot, ionized gas and hot dust streaming away from the nebula due to the relentless radiation.
Webb captures dying star's final 'performance' in fine detail
Tuesday, 12 July 2022 14:30Some stars save the best for last.
The dimmer star at the center of this scene has been sending out 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 this star is cloaked in dust.
Two cameras aboard Webb captured the latest image of this planetary nebula, cataloged as NGC 3132, and known informally as the Southern Ring Nebula. It is approximately 2,500 light-years away.
Webb will allow astronomers to dig into many more specifics about planetary nebulae like this one—clouds of gas and dust expelled by dying stars. Understanding which molecules are present, and where they lie throughout the shells of gas and dust will help researchers refine their knowledge of these objects.
This observation shows the Southern Ring Nebula almost face-on, but if we could rotate it to view it edge-on, its three-dimensional shape would more clearly look like two bowls placed together at the bottom, opening away from one another with a large hole at the center.
Webb reveals “Cosmic Cliffs” – a glittering landscape of star birth
Tuesday, 12 July 2022 14:22The NASA/ESA/CSA James Webb Space Telescope reveals emerging stellar nurseries and individual stars in Carina Nebula that were previously obscured.
The new images showcase how Webb’s cameras can peer through cosmic dust, shedding new light on how stars form. Objects in earliest, rapid phases of star formation difficult to capture, but Webb’s extreme sensitivity, spatial resolution, and imaging capability can chronicle these elusive events.
First images from Webb telescope reveal unseen Universe
Tuesday, 12 July 2022 14:22Highly anticipated observations hint at treasure trove of discoveries to come
The dawn of a new era in astronomy has begun as the world gets its first look at the full capabilities of the NASA/ESA/CSA James Webb Space Telescope. The telescope’s first full-colour images and spectroscopic data, which uncover a spectacular collection of cosmic features that have remained elusive until now, were released today.
Webb sheds light on galaxy evolution, black holes
Tuesday, 12 July 2022 14:13In this enormous new image, the NASA/ESA/CSA James Webb Space Telescope reveals never-before-seen details of the galaxy group “Stephan’s Quintet”.
Close proximity of the system gives astronomers a ringside seat to galactic mergers and interactions. Webb’s new image also shows in rare detail how interacting galaxies trigger star formation in each other and how gas in galaxies is being disturbed and the outflows driven by a black hole in Stephan’s Quintet in a level of detail never seen before. Tight galaxy groups like this may have been more common in the early Universe when superheated, infalling
La NASA revela las primeras imágenes del telescopio Webb de un universo nunca antes visto
Tuesday, 12 July 2022 14:02Webb captures dying star’s final ‘performance’ in fine detail

Webb reveals steamy atmosphere of distant planet in exquisite detail
Tuesday, 12 July 2022 13:46Webb’s enormous mirror and precise instruments joined forces to capture the most detailed measurements of starlight filtering through the atmosphere of a planet outside our Solar System to date.
The spectrum of light – which contains information about the makeup of a planetary atmosphere 1,150 light-years away – reveals the distinct signature of water. The strength of the signal that Webb detected hints at the significant role the telescope will play in the search for potentially habitable planets in the coming years. Webb’s powerful new view also shows evidence of haze and clouds that previous studies
