Punch Mission Instruments collects the first image
On April 14, 2025, the SWRI-led Punch Mission opened the doors of two instruments, collecting this first light image, showing that the camera was focusing, working properly, and capturing the universe’s glare in space deep in the “night” sky. You can see several familiar constellations, such as Taurus (right side of the top center) and Pleiades (top right). The soft…

Image: Lupus Chance Alignment
Credit: ESA/Hubble & NASA, D. Thilker The subject of this week’s NASA/ESA Hubble Space Telescope photography is the stunning Spiral Galaxy NGC 5530. The NGC5530 is located 40 million light years away from Constellation Lupus. This galaxy is classified as a “flocculant” spiral. In other words, the spiral arm is patchy and obscure. Some galaxies have a very bright center,…

Quantum imaging methods developed to enhance image clarity
Credit: Applied Physics Review (2025). doi:10.1063/5.0234062 For decades, quantum imaging has promised sharper images and greater light sensitivity than classical methods by exploiting the unique properties of quantum light, such as photon entanglement. However, the approach to doing so relies on delicate, specially designed light sources that are easily overwhelmed by real-world noise, making it difficult to produce quantum light…

Image: Milky Way on the horizon
Credit: NASA/Don Pettit NASA astronaut Dom Petitt used a camera with low light and long-term settings to capture images of the Milky Way appearing across the Earth’s horizon on January 29, 2025. At the time, the International Space Station orbited 265 miles above the Pacific Ocean off Chile just before sunrise. Pettit is part of the crew of the Expedition…

Fiber image transmission technology has been developed for minimal invasive endoscopes
Schematic diagram of a fiber-integrated miniature DN2 for all optical image transport via MMF. Credit: Nature Photonics (2025). doi:10.1038/s41566-025-01621-4 Optical fibers are fundamental components of modern science and technology due to their inherent advantages, providing efficient and secure media for applications such as Internet communication and big data transmission. Compared to single mode fiber (SMF), multimode fiber (MMFS) can support…

Image: Earth in far ultraviolet light
Credit: NASA On April 21, 1972, NASA astronaut John W. Young, commander of the Apollo 16 mission, took a deep-ultraviolet photo of Earth with an ultraviolet camera. Young’s original black and white photograph was printed three times on Agfacontour professional film, recording only one light level at each exposure. The three light levels are then colored blue (darkest), green (next…

Researchers improve chaotic mapping for super-resolution image reconstruction
Illustration of the proposed model. Credit: Sensor (2024). DOI: 10.3390/s24217030 Super-resolution (SR) technology plays a vital role in improving image quality. SR reconstruction aims to generate high-resolution images from low-resolution images. Traditional methods often result in blurry or distorted images. Although advanced techniques such as sparse representations and deep learning-based methods have shown promising results, they still face limitations in…

Image: NASA’s Terra satellite captured the shadow of the 2015 solar eclipse.
Credit: NASA Goddard MODIS Rapid Response Team On the morning of March 20, 2015, a total solar eclipse was visible in parts of Europe, and a partial solar eclipse was visible in North Africa and northern Asia. NASA’s Terra satellite passed over the Arctic Ocean on March 20 at 10:45 a.m. UTC (6:45 a.m. EDT), capturing the shadow of the…

Image processing method to enhance visualization of electron microscope images of rubber materials
Provided by: University of Tsukuba Researchers at the University of Tsukuba have developed a new imaging method to clearly visualize nanoscale structures within rubber materials. The research is published in the journal ACS Applied Nano Materials. Traditional electron microscopy often produces noisy images that obscure the internal contours of the rubber. The proposed method succeeded in capturing the reticular molecular…
