The missing 500 million: Cosmic bombardment melted Earth's first crust
New research suggests an extended period of intense asteroid bombardment prevented Earth's early crust from forming and may have influenced the origins of life.

The brief
Scientific studies indicate that a barrage of asteroid impacts kept the planet in an extremely high-temperature state during its early history. This period of bombardment effectively melted Earth's first crust for a duration of 500 million years, delaying the formation of continents.
Coverage from ScienceDaily, Universe Today, Ars Technica, Baku.ws, and Inshorts highlights the link between these cosmic impacts and the geochemical conditions of early Earth. Reports note that these conditions potentially provided the environment necessary to spark biological life.
Future developments will focus on how this period of intense bombardment shaped subsequent planetary evolution. Coverage does not yet specify the exact mechanism by which these impacts facilitated the transition to life.

Quick answers
Why was Earth unable to form a crust?
According to coverage, an extended barrage of asteroid impacts maintained temperatures too high for a stable crust to develop.
How long did this process last?
Reports identify a missing 500 million year period during which the planet's initial crust remained in a melted state.
What is the connection to the origin of life?
Scientific reports suggest that the heat and conditions caused by these asteroid impacts may have played a role in sparking life on Earth.
