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 (exoplanets). They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems. This way they address…

Experience one hundred years of astronomy at the Old Observatory
How big is the universe? How do stars form and evolve? And does life exist elsewhere in the Universe? These main questions in astronomy are the themes of the new exhibition Above & Beyond, which was created in honour of the hundredth anniversary of the International Astronomical Union (IAU). The exhibition…

Black holes like to eat, but have a variety of table manners
All supermassive black holes in the centres of galaxies appear to have periods when they swallow matter from their close surroundings. But that is about as far as the similarities go. That's the conclusion reached by British and Dutch astronomers from their research with ultra-sensitive radio telescopes…

Scientists discover the largest stellar black hole in the Milky Way
A European team of astronomers has discovered the largest stellar black hole in the Milky Way. It is more than thirty times as massive as our sun and is located in the constellation of Aquila, about two thousand light-years from Earth. The astronomers stumbled upon the black hole by chance while preparing…

Here is how you can help astronomers to identify black holes
Scientists are asking your help to find the origin of hundreds of thousands of galaxies that have been discovered by the largest radio telescope ever built: LOFAR. Where do these mysterious objects, which extend for thousands of light-years, come from? A new citizen science project called LOFAR Radio…

Astronomers discover furthest radio galaxy ever
After almost twenty years the record for the most distant radio galaxy has been broken. A team of astronomers led by Leiden PhD candidate Aayush Saxena has discovered a radio galaxy from the time when the universe was just one billion years old. The galaxy is at a distance of 12 billion light years…

Astronomers capture first image of a black hole
For the first time, astronomers have managed to take a photo of a supermassive black hole and its shadow. They used the Event Horizon Telescope (EHT), a worldwide network of eight radio telescopes that together form a virtual telescope the size of the earth. The news was presented in six press conferences…

Clashing galaxy clusters and extreme energies
A galaxy is already incredibly large, but it can get even bigger. Astronomer Reinout van Weeren investigates clusters of galaxies, one of the largest structures in the universe. For his research into the origins and evolution of these clusters, he obtained an ERC Starting Grant of 1.5 million euros.…

Auroras on nineteen stars hint at hidden exoplanets
An international team of scientists including Leiden's Joe Callingham has discovered nineteen red dwarf stars that unexpectedly emit radio waves. The outbursts possibly originate from interaction with exoplanets. The results of the research appear in two scientific publications.

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…

Astronomers see whirlwind around possible exoplanet-in-the-making
An international team of astronomers led by researchers from the Leiden University has discovered a whirlwind of dust and pebbles in orbit around a young star. It is possible that a planet is forming in the pebbles. The team of scientists made the discovery during the time that designers and developers…

Exhibition 'The Drake Equation' - online
In Green Bank, Virginia are some giant radio telescopes which astronomers use to study objects deep in space. Because these telescopes are built to capture very faint redio signals, the area around the observatory is officially a 'radio-quiet' zone, without WiFi, radio or Cell signal. Photographers…

Football molecule explains 100-year-old astronomical problem
Exactly a century ago, astronomers observed the first two diffuse interstellar bands (DIBs) in space. A DIB manifests itself as a colour of light that is missing in the radiation from stars behind an interstellar cloud. Although about 500 DIBs are yet discovered, they remained inexplicable until recently.…
