The dense white dwarf absorbs hydrogen gas shed from the red giant's outer later, eventually acquiring so much material that the white dwarf overheats and erupts in a massive thermonuclear explosion called a nova. This occurs cyclically in recurrent nova systems, and for RS Ophiuchi, a cycle lasts approximately 15 years.<br><br>The team of astronomers observed RS Ophiuchi's most recent nova using the dual Major Atmospheric Gamma Imaging Cherenkov (MAGIC) telescopes in Spain's Canary Islands, which revealed the presence of highly energetic gamma-rays with a value of 250 gigaelectronvolts (GeV) — among the highest energies ever recorded for a nova.<br><br>The explosion created shock waves that accelerated particles to nearly the speed of light. Based on these observations, scientists now theorize that "gamma-rays emanate from energetic protons, nuclei of hydrogen atoms," the researchers said in a statement. <br></p>
