Mesmerising images from James Webb space telescope
The 'deepest and sharpest' image of the Universe to date: the first photos from the new James Webb space telescope yesterday mesmerised astronomers and the public alike. Leiden Professor of Molecular Astrophysics, Ewine van Dishoeck, spoke to various media outlets about the first images, which include…

Webb detects icy ingredients for making potential habitable worlds
An international team of astronomers, led by Will Rocha of Leiden Observatory, using the NASA/ESA/CSA James Webb Space Telescope have discovered that the key ingredients for making potentially habitable worlds are present in early-stage protostars, where planets have not yet formed.

Ewine van Dishoeck goes stargazing
From the birth of the universe to the molecules in a planet's atmosphere. The first five pictures from the James Webb Space Telescope (JWST) show the enormous range in which the space telescope can operate. Ewine van Dishoeck, professor of molecular astrophysics, took a look at the first images Tuesday…

Vici grant for research on the formation of galaxies
How do galaxies form? That is what astronomer Mariska Kriek will be researching in the coming years. She received an NWO Vici grant of 1.5 million euros to study galaxies in the early universe. ‘This research uses new and unprecedented observations from the James Webb Space Telescope (JWST). These allow…

Star birth: a slow and mysterious drama
A star does not just appear in the sky overnight. Its creation takes tens of thousands of years. Twenty years ago, astronomers took a picture of a star in its birth phase. The James Webb Space Telescope (JWST) could now capture that same star in much greater detail. This does not only provide beautiful…

Astronomers spot benzene in planet-forming disk around star for first time
An international team of astronomers including Leiden professor Ewine van Dishoeck has observed the benzene molecule (C6H6) in a planet-forming disk around a young star for the first time. The observations tell us more about the forming of planets in this disc, like our own Earth. The scientists publish…

First detailed picture of ice in planet-forming disk
An international team of astronomers led by Ardjan Sturm of the Observatory has made the first two-dimensional inventory of ice in a planet-forming disk of dust and gas surrounding a young star. The researches, including Melissa McClure, used the James Webb Space Telescope and publish their findings…

Leiden PhD student discovers thin atmosphere on exoplanet TRAPPIST-1 c with JWST
A group of astronomers led by Leiden PhD student Sebastian Zieba has discovered using the James Webb Space Telescope (JWST) that the rocky exoplanet TRAPPIST-1 c has a thin atmosphere. Although the planet is nearly identical to Venus in size and temperature, and was expected to have a thick atmosphere,…

Tracking the origin and evolution of molecules in space
How do molecules originate and evolve in space? And how does that ultimately determine the chemical composition of planets and their atmospheres? The Dutch Astrochemistry Network (DANIII) receives 1.6 million euros from NWO to find out. A large group of Leiden astronomers and chemists is contributing:…

What was there first? Water or planets?
Could water be present in planet-forming disks before the formation of rocky planets? The James Webb Space Telescope may have found evidence for that. Webb has for the first time observed water in the inner disc around young star where at greater distance, giant planets have already formed. The research…

How the speed demons of the universe tell us something about the Milky Way
They hurtle along at over a thousand kilometres per second: the fastest stars in the Milky Way. PhD candidate Fraser Evans conducted research into these elusive hypervelocity stars and discovered that they have a lot to teach us, about black holes and supernovae, for example.
