![]() Meanwhile, other gleaming features in the image include older stars and distant background galaxies.ĭwarf galaxies were common early in the history of the universe and eventually merged to create larger, more structured galaxies. The blue light revealed in a composite image from these observations comes from newborn stars, while the glowing pink-red splotches may be hydrogen molecules that have heated after interacting with the light from the young, energetic stars. Hubble’s Wide Field Camera 3 and the Advanced Camera for Surveys observed UGC 8091 in different wavelengths of light. An irregular galaxy’s shape can be the result of interactions with other galaxies, as well as internal turbulence caused by celestial objects such as exploding stars. No two irregular galaxies look the same, and they appear in a range of sizes and shapes. The disorder is a result of UGC 8091 being an irregular galaxy that lacks the structured appearance of a spiral or elliptical galaxy. The galactic arrangement of the stars looks a bit like hopelessly tangled strings of lights that were hastily put away at the end of a holiday season. Hubble observed the billion stars that sparkle within a dwarf galaxy named UGC 8091, which is 7 million light-years from Earth in the Virgo constellation. The Hubble Space Telescope had to search a little farther to find a celestial winter wonderland. Young stars can release strong flares more powerful than those of our sun, and astronomers are still investigating the phenomena. Studying young stars such as those within the Christmas Tree Cluster offers insight into their volatile nature. ![]() White stars gleaming throughout the image were revealed by observations in infrared light with the Two Micron All Sky Survey, which operated between 19. Meanwhile, the cloud of gas resembling the festive tree glows in green optical light, as seen with the National Science Foundation’s WIYN 0.9-meter telescope on Kitt Peak in the Arizona-Sonoran Desert. ![]() In an animated version of the image, blinking blue and white lights represent the X-ray light from young stars detected by Chandra.
