Webb telescope captures images of new stars forming in Cat's Paw Nebula
The Cat's Paw Nebula is named after its resemblance to a feline footprint: The nebula appears to have three toes, colloquially called "toe beans," and a wider heel. The nebula is near the Scorpius constellation and is about 4,000 light-years from Earth, NASA said in a news release. The James Webb Telescope focused its Near-Infrared Camera on one of the "toe beans" to look through the gas and dust that make up the nebula.
The telescope found an "active star-forming region." The young stars, shown in yellow, appear to be "carving away at nearby gas and dust," NASA said.
The stars are also emitting bright light, represented in blue in the Webb images. Glowing red spots in the Webb images show areas where star formation is underway, NASA said. Other stars look blue-white. These ones have no radiation between themselves and Webb's camera, NASA said. At the bottom of the "toe bean" are small, dense filaments of dust that may be dense enough to collapse in on themselves and begin the process of becoming stars. The dust itself is imaged in brown.
The colorful scene is temporary, NASA said, but will shape the area's future.
"As a consequence of these massive stars' lively behavior, the local star formation process will eventually come to a stop," NASA said.
The images were released to celebrate the third anniversary of the telescope, which launched in July 2022. Since then, it has made a number of discoveries, including showing that the universe evolved faster than astronomers believed, NASA said. The telescope has also imaged a number of stars and planets, and identified asteroids that might come near Earth.
"Three years into its mission, Webb continues to deliver on its design – revealing previously hidden aspects of the universe, from the star formation process to some of the earliest galaxies," said Shawn Domagal-Goldman, acting director of the Astrophysics Division at NASA Headquarters in Washington. "... The questions Webb has raised are just as exciting as the answers it's giving us."

Deepest-Ever Field Image of Giant Galaxy Cluster Is a Brutal Reminder of Your Cosmic Insignificance
When it comes to deep space observations, our cosmological insignificance seems to grow with the resolution of our telescopes' cameras. In the latest advance, astronomers constructed the deepest-ever images of Abell 3667, a massive galaxy cluster located 700 million light-years from Earth—and most of the tiny dots you see represent entire galaxies. But the latest images of Abell 3667 also offer 'whispering evidence of past galactic interactions,' which astronomers document in detail in a paper published today in The Astrophysical Journal Letters. The team, led by astronomers from Brown University, caught Abell 3677 at a particularly lustrous moment in space-time, during a merger of two of the clusters' brightest galaxies. The stellar union, resembling a starry bridge stretching across the cluster, generated powerful gravitational bursts that yanked away the occasional stray star from other galaxies. Together, these lone stars emit a faint glow known as intracluster light (ICL)—and it's this phenomenon that researchers are investigating to explore Abell 3677's past. Specifically, it appears likely that Abell 3667 also formed from the rapid merger of two galaxy clusters, which previous X-ray and radio observations had predicted. This latest observation, however, represents the first ever optical evidence to support this idea. 'This is the first time a feature of this scale and size has been found in a local galaxy cluster,' Anthony Englert, study lead author, said in a statement. 'We knew that it was possible for a bridge like this to form between two galaxies, but it hadn't been documented anywhere before now. It was a huge surprise that we were able to image such a faint feature.' The team had an unusually long observation period for this project, which partly enabled them to construct such a detailed image. In addition to the intracluster light, the researchers captured faint, wispy puffs of cosmic dust called integrated flux nebulae, seen as bluish ribbons of light streaking across the image. 'It was just a happy coincidence that so many people had imaged Abell 3667 over the years, and we were able to stack all of those observations together,' Englert noted. The researchers have some outstanding questions about Abell 3677 and, more importantly, intracluster light. Fortunately, their timing couldn't have been more impeccable; with the Rubin Telescope officially up and running, astronomers are now better equipped to further probe these questions. 'Rubin is going to be able to image ICL in much the same way as we did here, but it's going to do it for every single local galaxy cluster in the southern sky,' Englert said. 'What we did is just a small sliver of what Rubin is going to be able to do. It's really going to blow the study of the ICL wide open.' Essentially, if this new image doesn't make you feel small, you might want to wait for the soon-to-come Rubin versions of this image. In fact, if Englert is right, we'll be seeing multiple versions of this image, and in higher resolution, too. So, for better or worse, we humans will only get smaller from here.

Interlune will team up with Astrolab to send a camera to the moon for helium-3 survey

(Astrolab Illustration) Seattle-based Interlune says it's struck a deal with California-based Astrolab to send a multispectral camera to the moon to estimate how much helium-3 is present in lunar soil. Interlune's camera will be one of the payloads aboard Astrolab's FLEX Lunar Innovation Platform rover, or FLIP for short. The FLIP rover is scheduled to take a piggyback ride to the moon's south polar region aboard Astrobotics' Griffin lander as soon as late 2025. The mission will mark Interlune's first off-Earth step in its campaign to identify and extract helium-3 from the moon and return it to Earth. Helium-3 can be used for applications ranging from quantum computing to security screening to fusion energy production. But it's rare on Earth: Interlune has pegged the commercial price of helium-3 at as much as $20 million per kilogram. Interlune is betting that lunar helium-3, which is produced when charged particles from the sun hit moon dirt, will become a cheaper source — and a source of revenue for the startup. The multispectral camera that Interlune has developed in partnership with NASA's Ames Research Center will be used to estimate helium-3 quantities and concentration around Griffin's landing site, without having to bring samples back to Earth. 'This is our first lunar mission and a seminal milestone toward being the first company to harvest natural resources from space,' Interlune's co-founder and CEO, Rob Meyerson, said today in a news release. 'Astrolab's ability to provide reliable mobility on the moon to partners like Interlune is the quintessential example of the collaboration and innovation building the lunar economy.' Astrolab's founder and CEO, Jaret Matthews, said his company was 'thrilled to be carrying Interlune's multispectral camera to the moon.' 'This is exactly the kind of mission we built Astrolab for — delivering breakthrough science to the lunar surface,' Matthews said. Interlune was founded in 2020 and raised $18 million in seed capital last year. In May, the startup announced that the U.S. Department of Energy and Maybell Quantum Industries would be among its first customers. At the time that announcement was made, Interlune said it would start delivering helium-3 in 2029.
