Beads of Glass in Meteorites help scientists piece together how Solar System formed

Scientists reveal conditions in early solar system. Ever since scientists started looking at meteorites with microscopes, they’ve been puzzled — and fascinated — by what’s inside. Most meteorites are made of tiny beads of glass that date back to the earliest days of the solar system, before the planets were even formed.

Scientists find evidence the Early Solar System Harbored a Gap between its Inner and Outer regions

The cosmic boundary, perhaps caused by a young Jupiter or a wind from the solar system emerging, likely shaped the composition of infant planets. In the early solar system, a “protoplanetary disk” of dust and gas rotated around the sun and eventually coalesced into the planets we know today.

A new analysis of ancient meteorites by scientists at MIT and elsewhere suggests that a mysterious gap existed within this disk around 4...
