Astrobiology, the Emergence of Life, and Planetary Exploration

Astrobiology brings together scientific disciplines focused on deciphering the origin of life, its nature, evolution, and distribution in the universe. Exceptionally rapid progress in our

Editorial : Special issue “ Planetary evolution and life ”

Given the enormous number of stars in the universe and the number of confirmed and postulated planets in our galaxy, it is generally agreed that our home planet Earth is not likely to be unique

How common are Earth-Moon planetary systems?

Rare Earths and Life Unseen

Speculation that alien life might be found on other worlds can be traced to ancient times. Copernicus, Kepler, and Galileo fed those thoughts by showing that the Earth is not the center of the

From Earth to the Universe: Life, Intelligence, and Evolution

While the scientific discourse on astrobiology—the study of the origin, evolution, and distribution of life in the universe—leans toward optimism about the possibility of extraterrestrial life,

The Biological Universe Revisited

Cosmic Evolution has been seen as leading to two possible world views: a physical universe in which life is rare or unique to Earth, and a biological universe, in which the processes of cosmic

Search for Life in the Universe ‐ What can we Learn from our own Biosphere?

Space exploration has extended the boundaries of biological investigations beyond the Earth to other planets, moons, comets, meteorites, and space at large. This field is covered by the new

Bayesian analysis of the astrobiological implications of life’s early emergence on Earth

Although terrestrial life's early emergence provides evidence that life might be abundant in the universe if early-Earth-like conditions are common, the evidence is inconclusive and indeed is consistent with an arbitrarily low intrinsic probability of abiogenesis for plausible uninformative priors.

Impact melting of frozen oceans on the early Earth: Implications for the origin of life

It is shown that bolide impacts between about 3.6 and 4.0 billion years ago could have episodically melted an ice-covered early ocean and could have been important for the initiation of abiotic reactions that gave rise to the first living organisms.

New Views on an Old Planet

Earth Science is history, and because the earth is changing every day, earth history is being added every moment. Professor van Andel's now famous book on earth history Light from a host of snowfall

Earth's early atmosphere

  • 1993
A better understanding of past atmospheric evolution is important to understanding the evolution of life and to predicting whether Earth-like planets might exist elsewhere in the galaxy.

Planetary atmosphere evolution:Do other habitable planets exist and can we detect them?

The goal of this conference is to consider whether it is possible within the next few decades to detect Earth-like planets around other stars using telescopes or interferometers on the ground or in

Warming Early Earth and Mars

In his Perspective, Kasting reviews the background to this paradox and comments on the results of Sagan and Chyba in the same issue, which are presented as a resolution to the dilemma.

Gaia: A New Look at Life on Earth

In this classic work that continues to inspire its many readers, Jim Lovelock puts forward his idea that the life of earth functions as a single organism. Written for non-scientists, Gaia is a

Thinking of biology: asteroid impacts, microbes, and the cooling of the atmosphere.

The authors examine the cooling of the Earth's surface from 3.75 to 1 billion years ago to propose the evolutionary sequence of microbes, which is proposed to be anaerobic heterotrophs, chemoautotophs, and then photoautotrophic microbes.

Evidence for life on Earth before 3,800 million years ago

IT is unknown when life first appeared on Earth. The earliest known microfossils (˜3,500 Myr before present) are structurally complex, and if it is assumed that the associated organisms required a
