WebApr 7, 2024 · A new study by NASA-supported scientists has shown that differentiated planetesimals may not have been a likely source of water for the early Earth. The timing and delivery of water to the early Earth is an important aspect in understanding how our planet became habitable for life. WebIn the inner, hotter part of the solar nebula, planetesimals were composed mostly of silicates and metals. In the outer, cooler portion of the nebula, water ice was the dominant component. The Sun's light warmed the objects in our solar system, especially those in the inner solar system.
