Radioaktivität

Bildinfo und Lizenz

Bildinfo

• Atomkerne senden kleinere Teilchen, auch Partikel genannt, mit hohen Geschwindigkeiten aus: dieses Phänomen nennt man Radioaktivität.
  

• This diagram illustrates why NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, can see radioactivity in the remains of exploded stars for the first time: One of the radioactive elements created in supernovas is titanium-44 (44 denotes the total number of protons and neutrons in an atom). Titanium-44 decays into calcium-44, and in the process, gives off high-energy X-ray photons. NuSTAR is the first telescope capable of creating detailed pictures of these high-energy X-ray photons. As a result, NuSTAR can map the radioactivity in supernova remnants for the first time, revealing new details about how massive stars explode.
