Young suns and infant planets: Probing the origins of solar systems
Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

Leiden astronomers find building blocks for life in the darkest spots of star-forming cloud
An international team led by Leiden astronomers has discovered diverse ices in the darkest, coldest regions of a molecular cloud. To do so, they used the James Webb Space Telescope. This discovery allows astronomers to examine the simple icy molecules that will be incorporated into future exoplanets,…

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…

How do you recognise the atmosphere of extraterrestrial lava worlds?
In the past 30 years, over 5,000 planets have been discovered outside our solar system. One common exoplanet is the lava world, a hot super-Earth with oceans of liquid lava. Mantas Zilinskas developed models to simulate possible atmospheres of these. Those simulations provide guidance for astronomers…

Oort Lecturer 2018: James Kasting about the search for life on planets around other stars
If there is life outside our galaxy, how could we find it? In his Oort Lecture, James Kasting talks about his search for simple life on other planets. Kasting was in the Netherlands for two weeks, because he was invited as the Oort Professor 2018.

First direct detection of a brown dwarf with a radio telescope
Astronomers at ASTRON and Leiden University have used the LOFAR radio telescope to discover a 'brown dwarf' – a faint object more massive than Jupiter, but significantly less massive than the Sun. The discovery of the object dubbed Elegast, opens up a new path that uses radio telescopes to discover…

Uncovering galaxy evolution and the nature of dark matter
Dark matter represents around eighty per cent of the total mass in the Universe. Yet, we still don't really know what it's made of. Astronomer Pavel Mancera Piña is looking for answers. With a Veni grant from NWO and the most advanced telescopes, such as the James Webb Space Telescope, he will investigate…

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…

Shopping City: Public Planning and Private Redevelopment in Britain since 1945
How have British cities changed in the years since the Second World War? And what drove this transformation? This innovative new history traces the development of the post-war British city, from the 1940s era of reconstruction, through the rise and fall of modernist urban renewal, up to the present-day…

Astronomers see disk around young super-Jupiter which may form moons
An international team of astronomers led by scientists from Leiden Observatory has for the first time characterised a dust disk surrounding a young super-Jupiter, which is either a giant planet or brown dwarf. They detected infrared emission from the disk which might indicate that moons may have formed.…
