(ORDO NEWS) — Japanese astronomers have found in the composition of matter from the asteroid Ryugu, extracted by the Hayabusa-2 probe, samples of gas that arose before the formation of the solar system 4.6 billion years ago, writes Yomiuri.
For this, 16 particles of the asteroid had to be heated to 1.8 thousand degrees Celsius. In this way, helium, neon and argon were obtained.
Their analysis showed that these substances may be older than the solar system.
As the researchers explained, initially the gas samples were stored as particles of diamonds and graphites scattered in space.
Subsequently, they served as material for the formation of a large asteroid, from which Ryugu then broke away.
