Description

Dead men tell no tales, but dead stars have plenty to say. Traces of elements left behind after stars explode can inform astronomers about how the star was ripped apart. NuSTAR, the first telescope capable of detecting high-energy X-ray signatures of radioactive elements in supernova remnants, recently captured a picture of a dying star’s last gasp. Science Bulletins is a production of the National Center for Science Literacy, Education, and Technology (NCSLET), part of the Department of Education at the American Museum of Natural History.
