Universe Awareness (UNAWE) started a crowdfunding campaign together with Design & Data GmbH, with a central role for the plush 'astronaut' Rosetta. This stuffed toy is used for interactive classes, in order to teach pupils across the world about astronomy and space sciences.

All comets might share their place of birth, new research says. For the first time ever, astronomer Christian Eistrup applied chemical models to fourteen well-known comets, surprisingly finding a clear pattern. His publication has been accepted in the journal Astronomy & Astrophysics.

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,…

An international team of researchers with Pascale Ehrenfreund from Leiden University has discovered that the dust particles of comet 67P/Churyumov–Gerasimenko are made up of even smaller particles. This discovery confirms that clumps of dust form the basis for comets and planets.

Amino acids are the building blocks for life on earth. They may originate in space and reach the Earth via comets and meteorites. Daniël Paardekooper examined part of this hypothesis. PhD defence on 5 July.

More than 100 teachers, educators and policymakers from 25 countries gathered in Leiden from 18 October for the Space Education International Workshop. Their goal is to inspire children using astronomy and space sciences.
