Data from Fermi space telescope indicate, that something is having an influence on cosmic rays going through center region of Milky Way. Astronomers are still not sure what it is. One of the possible culprits is definitely the supermassive black hole Sagittarius A*, but there are other possibilities as well. Among them supernova remnants or windy nebulae.

Astronomers detected gamma radiation coming from the binary system RS Ophiuchi for a month after the thermonuclear explosion. This star system contains a small white dwarf and a red giant. According to a new study the radiation was emitted from winds of the secondary red giant star accelerated by the nova explosion.
