New Hubble photo shows cotton candy-like nebula in a nearby dwarf galaxy
Source: NASA The Large Magellanic Cloud (LMC), a nearby dwarf galaxy orbiting the Milky Way, has just received a stunning spotlight, thanks to the Hubble Space Telescope . Using five special filters, including ultraviolet and infrared, Hubble captured a breathtaking view of swirling gas and dust glowing in pink, blue, and green. These colorful wisps, nicknamed 'cotton candy clouds,' reveal active star-forming regions hidden to the human eye. The image is not just beautiful, it's full of important scientific data. Seen only from the Southern Hemisphere, the LMC offers a rare look into galaxy evolution and the life cycle of stars just 160,000 light-years from Earth. What are cotton candy clouds captured by Hubble telescope Hubble's Wide Field Camera 3 (WFC3) captured the scene using five filters, including ultraviolet and infrared, that isolate wavelengths invisible to our eyes. Each wavelength gets a distinct color assignment: shorter (UV) light becomes blue or purple, longer (IR) appears red. The result: shimmering gas clouds that resemble brightly coloured cotton candy The N11 Nebula: Candy Floss at Cosmic Scale The colourful filaments belong to N11 (also known as LHA 120‑N 11), the second‑largest star‑forming region in the LMC. Spanning about 1,000 light‑years, this nebula contains cavities and shells carved by young, massive stars and past supernovae. Its billowing pink gas resembles fairground candy floss, more intense and dramatic in close‑up views. Studying regions like N11 helps astronomers learn how stellar winds and radiation shape interstellar clouds and trigger new generations of stars. Where is it and why it matters The scene unfolds within the Large Magellanic Cloud, a dwarf satellite galaxy of the Milky Way, located about 160,000 light‑years away in the southern constellations Dorado and Mensa. Though small, the LMC plays a big role in understanding galaxy evolution. Alongside the Small Magellanic Cloud, it orbits the Milky Way and is connected by the Magellanic Bridge of gas. Scientists believe the LMC may interact with our galaxy in roughly 2.4 billion years, well before the predicted collision with Andromeda in about 10 billion years How Hubble turns raw data into vivid art The Hubble telescope collects data across multiple wavelengths. Experts then combine and assign colors to each filter's output, balancing aesthetics with scientific clarity. Blue or purple tones often represent ultraviolet, while reds correspond to infrared. Though the final image is visually striking, it's grounded in real measurements and helps researchers understand gas composition, density, and star‑forming activity within the nebula What makes the image special This Hubble photo stands out for its combination of scientific insight and visual beauty. It's a powerful example of how advanced space instruments can illuminate the interstellar medium, revealing stellar nurseries and the dynamic processes inside a neighbouring galaxy. For anyone curious about galaxy evolution, nebula structure, or how scientists convert invisible light into dazzling images, this view is both enlightening and inspiring.

What might look like sparkling wisps of candy floss, or cotton candy, are dusty gas clouds in the Large Magellanic Cloud, a dwarf galaxy, as imaged by the Hubble Space Telescope. The pink, blue and green colors are not only beautiful to look at but can inform the viewer about the many wavelengths that comprise this photo. A part of a nebula in a dwarf galaxy called the Large Magellanic Cloud, the photo by the Hubble Space Telescope shows a gas cloud strewn in front of a star field. This type of view is made possible by Hubble's cameras, including the Wide Field Camera 3 (WFC3) that was used to collect the observations for this image. WFC3 has a variety of filters, each of which lets through only specific wavelengths, or colors, of light. This image combines observations made with five of WFC3's different filters, including some that capture ultraviolet and infrared light that are outside the field of vision for the human eye. The Large Magellanic Cloud is located 160,000 light-years from Earth in the constellations Dorado and Mensa. It is the largest of the Milky Way's many small satellite galaxies. People often wonder if the colors depicted in photos like these match what humans would see if they were to travel to the location. The specialists who process Hubble's images combine the telescope's raw data to compose multi-colored images like this one. To do so, they assign a color to each wavelength filter. Visible-light observations are typically matched to the color that the filter allows through. As such, shorter wavelengths of light, such as ultraviolet, are usually colored in blue or purple hues, while longer wavelengths, like infrared, are typically shown in shades of red. This way, the images stay close to reality while adding in new information from the portions of the electromagnetic spectrum that humans cannot see with our eyes alone.

Hubble Space Telescope's 35th anniversary: See NASA's new out-of-this-world images
During its 35 years of orbiting the Earth, the Hubble Space Telescope has transmitted endless streams of magnificent images, confirmed the existence of "dark matter," and helped track a vagabond black hole moving through the Milky Way. To celebrate the Hubble telescope's 35th anniversary, NASA released some striking new images on Wednesday, including a bold rendition of Mars and a stunning photo of a moth-shaped nebula with a white dwarf star in the middle. Built by Lockheed Martin in Sunnyvale, California, the Hubble Space Telescope was launched on the space shuttle Discovery from Kennedy Space Center in Florida on April 24, 1990. Since it orbits above the Earth, it can capture better cosmic images than telescopes on the ground. Hubble has made more than 1.6 million observations over the course of its lifetime, NASA says. And Hubble's discoveries have spawned more than 21,000 peer-reviewed science papers. The James Webb Space Telescope, which orbits the sun, has captured much space news attention, but it certainly hasn't put Hubble out of business. The Hubble telescope was designed to be the first space-based observatory, which could be serviced and upgraded while it remained in orbit. It was named after Edwin Hubble, the astronomer who showed that other galaxies existed beyond our own and came up with a classification scheme distinguishing galaxies by shape. About the same size as a school bus, the Hubble telescope uses three types of instruments to capture images across the universe: Cameras: Hubble has two cameras – the Advanced Camera for Surveys (ACS), which is primarily used for visible-light imaging, according to NASA. The Wide Field Camera 3 (WFC3) views infrared and ultraviolet wavelengths for higher resolution, deeper images. The ACS was repaired and the WFC3 was installed during a May 2009 servicing mission involving five spacewalks by astronauts from the space shuttle Atlantis. Spectrographs: The Cosmic Origins Spectrograph is the most sensitive ultraviolet spectrograph ever, capturing light and breaking it down to assess temperature, density, chemical composition, and velocity of objects, such as stars and quasars. The Space Telescope Imaging Spectrograph, also repaired in 2009, captures many forms of light, including ultraviolet to near-infrared light. Interferometers: The telescope has three Fine Guidance Sensors used to target and measure the relative positions and brightness of stars. Mike Snider is a reporter on USA TODAY's Trending team.
