The very first stars likely formed when the Universe was only 100 million years old. Known as Population III stars, these stellar objects were so massive that when they exploded as supernovae they tore themselves apart, seeding interstellar space with a distinctive blend of heavy elements. By analyzing ULAS J1342+0928, one of the most distant known quasars, astronomers have now identified the remnant material of the explosion of a first-generation...

This Hubble image shows NGC 5495, a spiral galaxy some 319 million light-years away in the constellation of Hydra. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Five filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
