Habitable planets around pulsars theoretically possible
It is theoretically possible that habitable planets exist around pulsars, rotating neutron stars. Such planets must have an enormous atmosphere that convert the deadly X-rays and high energy particles of the pulsar into heat. That is stated in a scientific paper by astronomers Alessandro Patruno and…

Planet formation starts before a star is fully grown
A team of European astronomers under Leiden leadership has discovered that dust particles around a star already coagulate before the star is fully grown. These agglomerated dust particles are the first step in the formation of planets. The research publish their discovery in the journal of Nature As…

Colliding magnetic fields reveal unknown planets
Northern lights, stellar winds and exoplanets. This is what astronomer's PhD research revolved around.

Netherlands Veganland: a good idea? These are the outcomes of the thought experiment!
Less meat and dairy means more space for nature, leisure, climate, biodiversity, more justice, and it's good news for the economy. That's according to the thought experiment conducted by Strootman Landscape Architects and Leiden environmental scientists. They presented their findings on 11 April.

Widespread cultural diffusion of knowledge started 400,000 years ago
Different groups of hominins probably learned from one another much earlier than was previously thought, and that knowledge was also distributed much further. A study by archaeologists at Leiden University on the use of fire shows that 400,000 years ago knowledge and skills must already have been exchanged…

CO2-reduction and economic growth: can they go hand-in-hand?
Fearing a trade-off with economic growth, countries feel discouraged to cut their CO2 emissions. But do the two really not go together? Environmental scientist Ranran Wang and her colleagues investigated the relationship between economic growth and CO2 emissions in 73 countries from 1970 to 2016. Wang:…

Astronomers see two planets vacuuming around young star
Astronomers led by Leiden astronomer Sebastiaan Haffert have directly imaged two planets that are gravitationally carving out a wide gap within a planet-forming disk surrounding a young star. While over a dozen exoplanets have been directly imaged, this is only the second multi-planet system to be p…

Report: Tracking down green spaces in The Hague in places you don't always want to be
Although there is considerable evidence that nature in the city is beneficial to both people and animals, we still do not have an overall picture of those benefits. To rectify that, a Leiden PhD candidate and a student – armed with a cargo bike – are using The Hague as a life-size laboratory.

Freedom is important, commitment too
Professor Jan Willem Erisman is happy with the freedom at our University. But frameworks are needed, he believes. That is why he makes a proposal for such a framework from the perspective of his own profession. In fact, he makes a proposal for a wonderful ambition for Leiden University.

Giant planet at large distance from sun-like star puzzles astronomers
A team of astronomers led by Dutch scientists have directly imaged a giant planet orbiting at a large distance around a sun-like star. Why this planet is so massive, and how it got to be there, is still a mystery. The researchers will publish their findings in the journal Astronomy & Astrophysics.

First discovery of methanol in a warm planet-forming disk
An international team of researchers led by Alice Booth (Leiden University, the Netherlands) have discovered methanol in the warm part of a planet-forming disk. The methanol cannot have been produced there and must have originated in the cold gas clouds from which the star and the disk formed. Thus,…

'Better to take action today, than to deal with the damage tomorrow'
It’s better to cut our nitrogen emissions now than to solve the consequences later at great expense. That’s the lesson we can learn from the Dutch nitrogen crisis, according to nitrogen expert Jan Willem Erisman. In Science, he shares this lesson with other countries. According to Erisman, we should…
