An international team of astronomers including Leiden scientists publishes the image of a young star with a surrounding dust disk that is still being fed from its surroundings. The phenomenon around the star SU Aur may explain why so many exoplanets are not neatly aligned with their star. The European Southern Observatory (ESO) has declared the image “Photo of the Week.”…

Big ideas in small packages: The seeds and worms making their way to the ISS
On Feb. 20, 2021, Northrop Grumman will launch its Cygnus cargo spacecraft aboard an Antares rocket to deliver several tons of cargo and supplies to the International Space Station for its 15th resupply mission (CRS-15). Included in these bulky supplies will be a handful of items that weigh no more than a few grams—a sampling of seeds, some microscopic proteins, and…
Ghana Scientist Tries Gene Editing To Create Healthier Sweet Potatoes
The Cornell Alliance for Science seeks to build “a significant international alliance of partners” to “correct misinformation and counter conspiracy theories” slowing progress on climate change, synthetic biology, agricultural innovations, and other issues. Slashdot reader wooloohoo shares their article about research on Ghana’s first gene-edited crop — a high-yielding sweet potato with increased beta carotone content. “For sweet potatoes, we want…

The First Black Hole Ever Discovered is More Massive Than We Thought
Neel V. Patel, writing at MIT Technology Review: Einstein first predicted the existence of black holes when he published his theory of general relativity in 1916, describing how gravity shapes the fabric of spacetime. But astronomers didn’t spot one until 1964, some 6,070 light-years away in the Cygnus constellation. Geiger counters launched into space detected cosmic x-rays coming from a region…
Astronomers publish map showing 25,000 supermassive black holes
An international team of astronomers has published a map of the sky showing over 25,000 supermassive black holes. The map, to be published in the journal Astronomy & Astrophysics, is the most detailed celestial map in the field of so-called low radio frequencies. The astronomers, including Leiden astronomers, used 52 stations with LOFAR antennas spread across nine European countries.

Facebook Blocks All News In and From Australia
Facebook said Wednesday that it would no longer allow Australian publishers to share news on Facebook or allow Australian people to view or share international news sources. From a report: The change comes as Australia prepares to pass a law that would require companies like Facebook and Google to pay news publishers to carry their stories. “The proposed law fundamentally misunderstands…
