Melting Pots for Life on Earth

Geochemists from Trinity College Dublin's School of Natural Sciences may have found a solution to a long-debated problem as to where - and how - life first formed on Earth.

A new study shown that meteorite impacts on ancient oceans may have created nucleobases and amino acids.

Sugars of extraterrestrial origin have been observed in the interstellar medium (ISM), in at least one comet spectrum, and in several carbonaceous chondritic meteorites that have been recovered from the surface of the Earth.

The insoluble organic matter (IOM) of an unequilibrated enstatite chondrite Sahara (SAH) 97096 has been investigated using a battery of analytical techniques.

Tales from a Martian Rock

A new analysis of a Martian rock that meteorite hunters plucked from an Antarctic ice field 30 years ago this month reveals a record of the planet's climate billions of years ago, back when water likely washed across its surface and any life that ever formed there might have emerged.

Research over the past four decades has shown a rich variety of complex organic molecular content in some meteorites.

Many aspects of planet formation are controlled by the amount of gas remaining in the natal protoplanetary disk (PPDs).

The finding of a 'cell-like' structure, which investigators now know once held water, came about as a result of collaboration between scientists in the UK and Greece. Their findings are published in the latest edition of the journal Astrobiology.

A spectral survey in the 1 mm wavelength range was undertaken in the long-period comets C/2012 F6 (Lemmon) and C/2013 R1 (Lovejoy) using the 30 m telescope of the Institut de radioastronomie millimetrique (IRAM) in April and November-December 2013.

Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis by NASA-funded researchers. The result supports a theory that the origin of life may have been assisted by a supply of key molecules created in space and brought to Earth by comet and meteor impacts.
