Graphic in two, stacked parts. The top part shows a roughly circular, wreath-like area of red, orange, beige, brown, and green clouds with many wisps and filaments. In the center of this wreath-like structure is a dark cavity filled with hundreds of sparkling, blue stars. The stars are not evenly distributed, with more on the right half of the image. Some blue stars also appear on top of the surrounding, wispy clouds. The bottom part of the graphic shows a yellowish-white star encircled by concentric, cloudy rings of increasing size. These rings are yellowish-white closest to the star, and they become darker the farther out they go. The farthest rings from the star appear fiery orange, and then become translucent as they trail off into the black background.
The ULLYSES program studied two types of young stars: super-hot, massive, blue stars and cooler, redder, less massive stars than our Sun. The top panel is a Hubble Space Telescope image of a star-forming region containing massive, young, blue stars in 30 Doradus, the Tarantula Nebula. Located within the Large Magellanic Cloud, this is one of the regions observed by ULLYSES. The bottom panel shows an artist’s concept of a cooler, redder, young star that less massive than our Sun. This type of star is still gathering material from its surrounding, planet-forming disk.

      A still image of a video that shows a plastic rod and cotton-fiberglass fabric being burned during a ground test of the Lunar-g Combustion Investigation (LUCI) experiment.Credit: Voyager Technologies An experiment studying how solid materials catch fire and burn in the Moon’s gravity was launched on Blue Origin’s New Shepard suborbital flight this month. 
      Developed by NASA’s Glenn Research Center in Cleveland together with Voyager Technologies, the Lunar-g Combustion Investigation (LUCI) will help researchers determine if conditions on the Moon – with reduced gravity – might be a more hazardous environment for fire safety. 
      The video shows a plastic rod and cotton-fiberglass fabric being burned during a ground test of the Lunar-g Combustion Investigation (LUCI) experiment. Scientists will compare the ground test video to the video recorded on the Blue Origin flight. 
      Credit: Voyager Technologies On this flight, LUCI tested flammability of cotton-fiberglass fabric and plastic rods, and once launched, the payload capsule rotated at a speed to simulate lunar gravity. NASA Glenn researchers will analyze data post-flight.

New, unburned samples were lit on fire during the flight. Credit: Voyager Technologies  LUCI’s findings will help NASA and its partners design safe spacecraft and spacesuits for future Moon and Mars missions.
