THE formation of the planets may have been less violent than we think. It is a small revolution in astrophysics that scientists have presented to the meetong of the American Association for the Advancement of Science in Seattle, presenting the data collected by the probe New Horizons. Clumps of matter would not be the result of collisions and catastrophic impacts, argue experts, because of the groupings progressive. A hypothesis that the research coordinator, Alan Stern , has defined a “discovery of stupendous magnitude” in an interview for the Bbc.

To clarify this hypothesis was the observation of Arrokoth (which means “heaven” in the language of the native american Powhatan / Algonquian), an element that is located at a distance of more than six billion kilometers from the Sun, in a region called the Kuiper belt, and has been observed thanks to the images of the probe Nasa, passed close to the object about a year ago.
