ALMA Reveals Inner Web of Stellar Nursery
Recent study led at the Leiden Observatory has observed Orion with unprecedented detail. New data from the Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes have been used to create this stunning image showing a web of filaments in the Orion Nebula. These features appear red-hot…

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…

To the edge of space and time
Large telescopes can look so deep into the Universe that they can also look back billions of years in time. From 2018, the successor of the Hubble Space Telescope, the James Webb Space Telescope, will be able to see the period just after the Big Bang, when the first stars and galaxies formed. Astronomers…

Exploring the Universe
Astronomers want to understand the Universe, from the Big Bang to the present day, and what the future will hold. In Leiden they focus on two key questions: ‘How did stars and planets originate’ and ‘How were galaxies and black holes formed in the young Universe?’ A new generation of telescopes – just…

Sources of Meaning among organized non-religious ‘secular’ persons
Recently, studies have shown the similarities and differences in sources of meaning between religionists, ‘nones’ and atheists (see several studies of Schnell and others). The present study that will be conducted in three European countries tries to clarify the relationship between meaning giving and…

Chemistry between stars and planets
In the large gas clouds between the stars, chemical reactions take place under extreme conditions, giving rise to both small molecules, such as water and common salt, as well as large complex molecules that can serve as the building blocks of life. This is known as astrochemistry and it is something…

Galaxy in the early Universe contains carbon after all
In 2015, Jorryt Matthee thought he discovered an extremely distant galaxy called CR7, which lacked elements heavier than helium. Three years later, he shows with measurements using the ALMA telescope that the galaxy does have carbon after all, and even in normal concentrations. The American Astronomical…

First photo of black hole at the heart of our Galaxy
Finally we know for sure that there is a black hole at the centre of our own galaxy. Today, astronomers unveiled the first ever photo of Sagittarius A*, a super-massive object at the centre of the Milky Way. This picture could only be taken thanks to the cooperation of telescopes worldwide.

Exo-planets, star and planet formation
At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…

High-mass stars are formed not from dust disk but from debris
A Dutch-led team of astronomers has discovered that high-mass stars are formed differently from their smaller siblings. Whereas small stars are often surrounded by an orderly disk of dust and matter, the supply of matter to large stars is a chaotic mess. The researchers used the Atacama Large Millimeter/submillimeter…

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,…

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…
