Beyond the borders of the Milky Way, scientists have discovered molecular oxygen, which is approximately five hundred million light years from us.
Astronomers previously observed oxygen molecules outside The solar system, now, thanks to the powerful 30-meter IRAM and NOEMA telescope, oxygen was detected near our galaxies.
Interestingly, oxygen is the third among the most common elements in space after hydrogen and helium, but its almost none in the solar system (in the interplanetary space).
Oxygen is also found in the constellation Orion, where this element in compound with hydrogen is present in the form of steam, which mixes up with dust particles.
Astronomers speculate that in the Markaryan galaxy 231 oxygen could result from a powerful explosion. Structure of this galaxies are significantly different from the structure of the Milky Way: this galaxy is powered by a quasar emitting light from the nucleus of a galaxy in the central region of which several black holes. Theoretically, the outflow of molecules in the galactic nucleus leads to explosions and subsequent release of oxygen.
