Traces of building block of life found around infant suns
ALMA has observed stars like the Sun at a very early stage in their formation and found traces of methyl isocyanate - a chemical building block of life. This is the first ever detection of this prebiotic molecule towards solar-type protostars, the sort from which our Solar System evolved. The discovery…
‘International isolation is not an option’
Security in the broadest sense of the word was the key focus in the Interfaculty Conference on 4 April in Leiden. With almost 200 attendees and such well-known speakers as Dick Schoof, Pieter van Vollenhoven and Ad Verbrugge, the first conference was a success.
Cosmic recipe discovered for making glycerol
A team of laboratory astrophysicists from Leiden University managed to make glycerol under conditions comparable to those in dark interstellar clouds. They allowed carbon monoxide ice to react with hydrogen atoms at minus 250 degrees Celsius. The researchers publish their findings in the Astrophysical…

Freon-40 may not be a useful marker of life
Observations made with the ALMA telescope in Chile and ESA’s Rosetta mission, have detected the faint molecular fingerprint of methyl chloride in gas, a chemical commonly produced by industrial biological processes on Earth, around both an infant star and a comet. Methyl chloride, also known as Freon-40,…
