A binary star system, 5,000 light-years from Earth, 식물 엑소즘 that explodes in a dramatic nova every 15 years has been seen by a pair of MAGIC telescopes.

RS Ophiuchi (RS Oph) is in the constellation of the Serpent Bearer and is made up of a white dwarf and 식물 엑소즘 a red giant that is on the cusp of burning up in a supernova.

Astronomers from the Max Planck Institute in studied the binary pair using the MAGIC telescope, a system of two Imaging Atmospheric Cherenkov telescopes at the Roque de los Muchachos Observatory on Palma, Canary Islands.

Every 15 yeas a dramatic explosion comes from this binary pair, as the red giant sheds its material, pulled on to the surface of the White Dwarf, a dead star.  

Birthplaces of a nova are systems in which two very different stars live in a parasitic relationship, usually a smaller and a larger star.

In this case a white dwarf, which is a small, burned-out and dense star , where a teaspoon of matter weighs 1 ton, 식물 엑소즘 orbits a red giant, an old star that will soon burn up.

The dying giant star feeds the white dwarf with matter shedding its outer hydrogen layer as the gas flows onto the nearby white dwarf. This flow of matter continues, until the white dwarf overeats itself and explodes.

The temperature and pressure in the newly gained stellar shells become too large and are flung away in a gigantic thermonuclear explosion. The dwarf star remains intact and the cycle begins again – until the spectacle repeats itself.

It had been speculated that such explosions involve high energies, but the exact details were unclear – especially for this particular nova.

The two MAGIC telescopes recorded gamma rays with the value of 250 gigaelectronvolts (GeV), among the highest energies ever measured in a nova.

In comparison, radiation is a hundred billion times more energetic than visible light.
