Hubble Captures Cotton Candy Clouds
This NASA/ESA Hubble Space Telescope image features a cloudscape in the Large Magellanic Cloud., a dwarf satellite galaxy of the Milky Way. ESA/Hubble & NASA, C. Murray This NASA/ESA Hubble Space Telescope image features a sparkling cloudscape from one of the Milky Way’s galactic neighbors, a dwarf galaxy called the Large Magellanic Cloud. Located 160,000 light-years away in the constellations Dorado and Mensa, the Large Magellanic Cloud is the largest of the Milky Way’s many small satellite galaxies.
This view of dusty gas clouds in the Large Magellanic Cloud is possible thanks to Hubble’s cameras, such as the Wide Field Camera 3 (WFC3) that collected the observations for this image. WFC3 holds a variety of filters, and each lets through specific wavelengths, or colors, of light. This image combines observations made with five different filters, including some that capture ultraviolet and infrared light that the human eye cannot see.
The wispy gas clouds in this image resemble brightly colored cotton candy. When viewing such a vividly colored cosmic scene, it is natural to wonder whether the colors are ‘real’. After all, Hubble, with its 7.8-foot-wide (2.4 m) mirror and advanced scientific instruments, doesn’t bear resemblance to a typical camera! When image-processing specialists combine raw filtered data into a multi-colored image like this one, they assign a color to each filter. Visible-light observations typically correspond to the color that the filter allows through. Shorter wavelengths of light such as ultraviolet are usually assigned blue or purple, while longer wavelengths like infrared are typically red.
This color scheme closely represents reality while adding new information from the portions of the electromagnetic spectrum that humans cannot see. However, there are endless possible color combinations that can be employed to achieve an especially aesthetically pleasing or scientifically insightful image.

Hubble Pinpoints Young Stars in Spiral Galaxy
This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 1317. ESA/Hubble & NASA, J. Lee and the PHANGS-HST Team In this image, the NASA/ESA Hubble Space Telescope peers into the spiral galaxy NGC 1317 in the constellation Fornax, located more than 50 million light-years from Earth. Visible in this galaxy image is a bright blue ring that hosts hot, young stars. NGC 1317 is one of a pair, but its rowdy larger neighbor, NGC 1316, lies outside Hubble’s field of view. Despite the absence of its neighboring galaxy, this image finds NGC 1317 accompanied by two objects from very different parts of the universe. The bright point ringed with a crisscross pattern is a star from our own galaxy surrounded by diffraction spikes, whereas the redder elongated smudge is a distant galaxy lying far beyond NGC 1317.
The data presented in this image are from a vast observing campaign of hundreds of observations from Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys. Combined with data from the ALMA array in the Atacama Desert, these observations help astronomers chart the connections between vast clouds of cold gas and the fiercely hot, young stars that form within them. ALMA’s unparalleled sensitivity at long wavelengths identified vast reservoirs of cold gas throughout the local universe, and Hubble’s sharp vision pinpointed clusters of young stars, as well as measuring their ages and masses.
Often the most exciting astronomical discoveries require this kind of telescope teamwork, with cutting-edge facilities working together to provide astronomers with information across the electromagnetic spectrum. The same applies to Hubble’s observations that laid the groundwork for the NASA/ESA/CSA James Webb Space Telescope’s scientific observations.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
When most people think of NASA, they picture rockets, astronauts, and the Moon. But behind the scenes, a group of inventors is quietly rewriting the rules of what’s possible — on Earth, in orbit, and beyond. Their groundbreaking inventions eventually become technology available for industry, helping to shape new products and services that improve life around the globe. For their contributions to NASA technology, we welcome four new inductees into the 2024-2025 NASA Inventors Hall of Fame
A robot for space and the workplace
Myron (Ron) Diftler led the team behind Robonaut 2 (R2), a humanoid robot developed with General Motors. The goal was to create a robot that could help humans both in space and on the factory floor. The R2 robot became the first humanoid robot in space aboard the International Space Station, and part of its technology was licensed for use on Earth, leading to a grip-strengthening robotic glove to help humans with strenuous, repetitive tasks. From factories to space exploration, Diftler’s work has real-world impact.
Some of the toughest electronic chips on and off Earth
Technology developed to one day explore the surface of Venus has to be tough enough to survive the planet where temperatures hit 860°F and the atmosphere is akin to battery acid. Philip Neudeck’s silicon carbide integrated circuits don’t just work — they ran for over 60 days in simulated Venus-like conditions. On Earth, these chips can boost efficiency in wireless communication systems, help make drilling for oil safer, and enable more practical electric vehicles.
From developing harder chip materials to unlocking new planetary missions, Neudeck is proving that the future of electronics isn’t just about speed — it’s about survival.
Hydrogen sensors that could go the distance on other worlds
Gary Hunter helped develop a hydrogen sensor so advanced it’s being considered for a future mission to Titan, Saturn’s icy moon. These and a range of other sensors he’s helped developed have applications that go beyond space exploration, such as factory floors here on Earth.
With new missions on the horizon and smarter sensors in development, Hunter is still pushing the boundaries of what NASA technology can do. Whether it’s Titan, the surface of Venus, or somewhere we haven’t dreamed of yet, this work could help shape the way to get there.
Advanced materials research to make travel safer
Advanced materials, such as foams and composites, are key to unlocking the next generation of manufacturing. From space exploration to industry, Erik Weiser spent years contributing his expertise to the development of polymers, ceramics, metals, nanomaterials, and more. He is named on more than 20 patents. During this time, he provided his foam expertise to the Space Shuttle Columbia accident investigation, the Shuttle Discovery Return-to-Flight Investigation and numerous teams geared toward improving the safety of the shuttle.
Today, Weiser serves as director of the Facilities and Real Estate Division at NASA Headquarters, overseeing the foundation of NASA’s missions. Whether it’s advancing research or optimizing real estate across the agency, he’s helping launch the future, one facility at a time.

Hubble Comes Face-to-Face with Spiral’s Arms
This Hubble Space Telescope image showcases the spiral galaxy NGC 3596. ESA/Hubble & NASA, D. Thilker The spiral galaxy NGC 3596 is on display in this NASA/ESA Hubble Space Telescope image that incorporates six different wavelengths of light. NGC 3596 is situated 90 million light-years from Earth in the constellation Leo, the Lion. British astronomer Sir William Herschel first documented the galaxy in 1784.
NGC 3596 appears almost perfectly face-on when viewed from Earth, showcasing the galaxy’s neatly wound spiral arms. These bright arms hold concentrations of stars, gas, and dust that mark the area where star formation is most active, illustrated by the brilliant pink star-forming regions and young blue stars tracing NGC 3596’s arms.
What causes these spiral arms to form? It’s a surprisingly difficult question to answer, partly because spiral galaxies are so diverse. Some have clear spiral arms, while others have patchy, feathery arms. Some have prominent bars across their centers, while others have compact, circular nuclei. Some have close neighbors, while others are isolated.
Early ideas of how spiral arms formed stumped astronomers with the ‘winding problem’. If a galaxy’s spiral arms are coherent structures, its arms would wind tighter and tighter as the galaxy spins, until the arms are no longer visible. Now, researchers believe that spiral arms represent a pattern of high-density and low-density areas rather than a physical structure. As stars, gas, and dust orbit within a galaxy’s disk, they pass in and out of the spiral arms. Much like cars moving through a traffic jam, these materials slow down and bunch up as they enter a spiral arm, before emerging and continuing their journey through the galaxy.
