This is how the universe was created: they discover a "missing link" of planetary formation

It has a radius of 1.3 kilometers. Japanese scientists announced yesterday in Nature Astronomy. It is the most distant object on Earth that has been found.

The solar system begins to unravel its mysteries. On January 1, the Nasa New Horizonsflew Ultima Thule and since then the North American space agency has spread several images about this body, the most distant and primitive already found by man.

The body without atmosphere that is in the belt Kuiper is a remnant of the formation of Solar system and its study appears as a fundamental question to discover the origin and the evolution of our planetary system.

Ultima Thule was formed there 4,500 million years and is more than 1 billion miles from Pluto. It is precisely their distance that makes their study difficult, because of their size, since these bodies are completely fragile and difficult to detect.

This is Bennu, the "death asteroid" that could collide with Earth

However, a group of Japanese astronomers managed to overcome this barrier and, with a low cost system, began exploration of the asteroid: two amateur telescopes, coupled with two commercial cameras, were sufficient to investigate it. On the terrace of a public center located on the Miyako, Okinawamore than 2000 stars between June 2016 and August 2017 in order to identify dissimulations.

The work collected 60 hours of images that occupied 50 terabytes of raw data. His analysis meant the first object to be found besides Pluto, with a radius of 1.3 km wide, and by its size and distance, the feat was doubly valuable.

According to what the magazine publishes Astronomy of Nature, Japanese astronomers had started a project called OASES, which worked through a coordinated system of several low-cost telescopes with high-speed, wide-field photometry to detect stellar occultations.
