Comets and life in the Universe.

Area of Science:

• Astrobiology
• Planetary Science
• Origin of Life Studies

Background:

• The hypothesis that comets provided key chemical ingredients for life's origin on early Earth has gained significant traction since 1961.
• Recent scientific meetings and symposia have focused on comets and their role in biogenesis.
• Extensive literature now addresses the contribution of cometary material to Earth's origins.

Purpose of the Study:

• To provide a concise review of the role of comets in the origin of life on Earth.
• To discuss the potential role of cometary material in the origin of life elsewhere in the universe.

Main Methods:

• Literature review of existing research on comets and origins of life.
• Synthesis of findings from recent scientific meetings and symposia.
• Analysis of recent discoveries relevant to cometary composition and delivery.

Main Results:

• The concept of cometary delivery of prebiotic molecules is well-supported by scientific discourse.
• Cometary material is considered a significant factor in Earth's chemical evolution leading to life.
• The potential for comets to facilitate life's origin extends to other celestial bodies.

Conclusions:

• Comets likely played a crucial role in supplying the necessary chemical precursors for abiogenesis on early Earth.
• The findings support further investigation into extraterrestrial organic chemistry and the universal potential for life's origins.
• This review consolidates current understanding and highlights future research directions.
