Like fresh fireworks launched against a background of dissipating smoke, blue and white stars shine brilliantly against a crimson background of glowing gas in this image of stellar nursery LH 95 from NASA’s Hubble Space Telescope.
LH 95 is a region in the Large Magellanic Cloud, a dwarf galaxy that orbits the Milky Way. Low-mass infant stars live alongside massive blue giant stars in what is known as a stellar association, one of many in the Large Magellanic Cloud.
The LH 95 region’s most massive stars, possessing at least three times the mass of the Sun and visible here as the largest and brightest blue stars, expel ultraviolet radiation and stellar winds that both heat and shape the surrounding hydrogen gas. Dark filaments stand out in sharp contrast against the glowing hydrogen where denser dust lanes resist erosion.
In this image, blue indicates the shorter wavelengths that are visible light, while red depicts the longer wavelengths of visible light, as well as some near-infrared light. Colors in Hubble images are chosen based on standard image processing techniques to best represent the wavelengths of light that pass through the filters used in the observation. The gas of the nebula glows crimson due to hydrogen-alpha emissions.
Hydrogen-alpha is an excellent indicator of star formation, allowing astronomers to identify very young stars embedded in this glowing gas. Researchers found developing stars still gathering material from the disks of gas and dust around them. In fact, LH 95 is home to an extraordinary 2,500 stars that have accumulated almost all of their critical mass but have not yet “turned on” by beginning fusion reactions. These stars, called “pre-main-sequence stars,” have formed from collapsing clouds of gas and are still contracting. They will soon begin burning hydrogen in their cores to become full stars.
By studying these forming stars, researchers confirmed that the stars’ accretion rate ― the rate at which they accumulate matter ― decreased with age, as expected. However, they also learned that accretion can persist for several million years, longer than sometimes assumed. This information helps refine our understanding of how young stars keep growing and how their disks evolve.
Researchers noted that distinct generations of stars in LH 95 exist side-by-side, indicating that rather than forming stars in a single event, the region produces multiple stellar generations over an extended period.
The most massive star in LH 95 (above center, slightly left) has about 60-70 times the mass of the Sun and is about a million years younger than the rest of stars in the system, which appear to be around 4 million years old. Massive stars like these burn through their fuel quickly and die in supernova explosions.
With its rich stellar population, LH 95 is valued by astronomers for providing a way to observe forming stars at relatively close range in an environment with less obscuring dust than similar regions of the Milky Way.
As one of NASA’s flagship observatories, Hubble has produced a wealth of scientific discoveries over more than 30 years in orbit. Its observations are expanded upon and enhanced by observations with other NASA missions, including the infrared-detecting Webb Space Telescope and the upcoming Nancy Grace Roman Space Telescope, which is scheduled to launch in late summer.

More than 500,000 stars blaze red, white, and blue in this image from NASA’s Hubble Space Telescope, released in celebration of the United States’ 250th anniversary. The image showcases Messier 3 (M3), one of the Milky Way galaxy’s most massive globular clusters, or spherical collections of gravitationally bound stars. Globular clusters are made up of ancient stars that formed at roughly the same time from the same cloud of gas, giving those stars similar ages. Around 150 known globular clusters are sprinkled around the outer regions of the Milky Way.
In addition to its significant mass, M3 is unusual because it lies relatively far from the galactic center and has more than 240 RR Lyrae variable stars, the most of any globular cluster in our galaxy. RR Lyrae variables are some of the galaxy’s oldest stars and are of special interest to astronomers, due to their age and because their light fluctuates over time in a way that tells us their intrinsic brightness. This true brightness can be used to measure distances in the cosmos, just as knowing the brightness of car headlights on a dark road can help estimate the distance to an oncoming vehicle.
The M3 globular cluster also contains around 70 identified “blue straggler” candidates, which are stars that shine with a bright, blue light that makes them look like younger stars than the typical, redder residents of globular clusters. This was the first cluster in which these oddball stars were located. These stars are thought to have gravitationally pulled mass from companion stars, rejuvenating them and making them appear bluer and younger despite their true age.
The unusual characteristics of M3 may arise from its origins. The globular cluster, which contains two distinct populations of stars, may be the result of a merger of two globular clusters. These two clusters were members of the same dwarf galaxy, which was later swallowed up by the Milky Way.
Hubble has taken several images of M3, also known as NGC 5272, documenting its complicated and intriguing characteristics. In this image, blue indicates the shorter wavelengths that are visible light, while red depicts the longer wavelengths of visible light, as well as some near-infrared light. Colors in Hubble images are chosen based on standard image processing techniques to best represent the wavelengths of light that pass through the filters used in the observation. Because the color and temperature of stars are directly related, we know that the blue stars in this image are hotter and the red stars are cooler.
This image is part of a Hubble Treasury program survey designed to observe approximately half of the Milky Way’s globular clusters to construct a detailed chronology of how the Milky Way galaxy formed. With over 30 years of observations, Hubble is one of NASA’s flagship observatories and works in complement with its sibling space missions, including the infrared-detecting Webb Space Telescope and the upcoming Nancy Grace Roman Space Telescope, to weave together a comprehensive picture of our vast universe.

Moon Mascot: NASA Artemis II ZGI Design Challenge
Last year, the Moon mascot design contest received thousands of submissions from more than fifty countries for the Artemis II mission’s zero‑gravity indicator. This plush item serves a special purpose — it begins to float once the astronauts reach space, signaling the onset of zero gravity. It also provides a comforting reminder of Earth when the crew is far from home.
Ultimately, the Artemis II astronauts selected “Rise”—inspired by the iconic Earthrise photograph captured during the Apollo 8 mission and designed by Lucas Ye of Mountain View, California—as the zero‑gravity indicator that will accompany them around the Moon. “Rise” also features a small pouch that will carry an SD card containing all 5.6 million names submitted through the Send Your Name with Artemis campaign.
Send Your Name with Artemis II
NASA invited the public to join the agency’s Artemis II test flight as four astronauts ventured around the Moon and back to test the systems and hardware needed for deep space exploration. As part of the agency’s “Send Your Name with Artemis II” effort, anyone could claim their spot by signing up before Jan. 21, 2026. Participants launched their names aboard the Orion spacecraft and SLS (Space Launch System) rocket alongside NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen.

NASA’s James Webb Space Telescope has captured the infrared light of numerous features that previously were impossible to see beyond the thick dust of the FS Tau star system. In addition to myriad background galaxies that burst into view like fireworks for the United States’ 250th anniversary celebrations, this image flickers with a number of protostars, or baby stars that are formed from dense pockets of gas and dust. These hot, clumpy, and low-mass objects eventually will become full-fledged stars capable of burning hydrogen in their cores, like our Sun. The protostars of FS Tau are about 1 to 3 million years old, which is relatively young in cosmic scales. Our Sun, by contrast, is 4.6 billion years old.
Low-mass stars emit less radiation and have less energetic stellar winds than those with larger masses, which means they disrupt their environment at a much lower level. This makes the FS Tau region incredibly useful for studying low-mass star evolution without the same level of environmental interference seen near higher-mass stars. A pair of protostars that creates the largest diffraction pattern seen slightly to the left of center in the image, called FS Tau A, is about half the mass of our Sun.

Even though these objects are young and low-mass, they still can impact their surroundings, partially due to the outflows they emit. These outflows, seen as orange and red wisps and wide sheets, are theorized to come from FS Tau B, the protostar slightly to the right of center that has an orange diffraction pattern. As FS Tau B feeds on the surrounding dust and gas to grow, it ejects some of that matter outward. The wider outflows are thought to come from the interaction between the protostar’s magnetic field and superheated matter closest to the protostar within its accretion disk. The disk is seen as a dark band that cuts across at a 30-degree angle.
The gaps between the outflows, newly discovered in this Webb observation, add to growing evidence that protostars accrete matter in discrete episodes. In the periods where protostars gather material and increase in mass, they also eject superheated matter in different directions. In between these episodes, they are relatively quiet.

As protostars eject these outflows, they shape their surroundings. This is best shown by the prominent light-blue ridges of dust and gas near FS Tau B. These thicker regions were likely created as outflows struck and compressed matter together. The brightness of these light-blue ridges shows that the nearby protostar’s light is reflected. Moreover, Webb’s sensitivity reveals the varying textures of dust and gas across the entire region.
The range of colors seen in this observation also provides a wealth of information, specifically about where dust is and how much of it obscures the region. Light with bluer wavelengths is absorbed and scattered by dust, while redder-wavelength light is able to slip through. Therefore, background galaxies behind thicker foreground dust appear redder. Alternatively, yellow galaxies have much less dust obscuring them. The few white stars visible in this image are likely in the foreground.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).
