The beginning of another “Another Earth”?-Information Technology

An eerie, shadowy and chaotic object has entered the view of NASA’s Spitzer Space Telescope, yielding surprising data that could help Earthlings peer into the past.

A team of scientists led by Dr. George Rieke from the Steward Observatory and the University of Arizona’s Lunar and Planetary Laboratory have studied the “cosmic specter” and published surprising results.

Citing research, Sci-News reports that its nature is a young, 10 million-year-old star called HD166191.

What creates the strange and chaotic “ghost” surrounding the star is the remnants of a collision of “planetary seeds” – the first-generation planets of a star system, producing only to smash together and break apart, then these fragments will mix and coalesce into real planets.

Currently, the fragment of these planetary seeds is still forming a large dust cloud, and during Spizer’s observations, it passed in front of the star, creating an image of an opaque, airless ghost. clear shape.

To create such a large dust cloud, the planetary seeds involved in the collision must be quite large, about the size of dwarf planets like Vesta in the solar system.

Dr Kate Su from the University of Arizona’s Steward Observatory, a member of the research team, said looking at the young star system is like a way we look back into the past of the solar system itself, understanding how the stars A rocky planet like Earth was born.
