https://doi.org/10.1007/978-3-322-84328-9Aromatic material extracted from the Murchison meteorite shows an absorption at λ2 200 Å similar to the well-known interstellar absorption feature at this wavelength. This suggests a link between interstellar grain clumps containing organics and the presolar component of carbonaceous chondrites.

Panspermia 2000The idea that life is a cosmic phenomenon has a history spanning many centuries and many cultures. In most ancient philosophies of the Orient - for instance in Vedhic and Buddhist writings - the cosmic nature of life is taken for granted: It is regarded as an inherent property of a Universe that is itself infinite, timeless and eternal.

Metallic Particles in AstronomyWe discuss some implications of iron whiskers condensing in supernova ejecta and being expelled into interstellar and intergalactic space. The supposition that the universal microwave background is a relic from an early hot state of the Universe is shown to be not as secure as is commonly supposed.

The Universe and Life: Deductions from the Weak Anthropic PrincipleThe existence of life in the Universe is interpreted in terms of the’ Weak Anthropic Principle’. It is shown that cosmological models are constrained to a class that involves an open timescale and access to infinite quantities of carbonaceous material.
