How Heavy Can a Neutron Star Get?

The physics of neutron stars are almost too fantastic to believe. Something the weight of two Suns compacted to a sphere the size of a city. Each teaspoon of its material would weigh billions of tons....

🚀 Lors d'essais de qualification sur l'inter-étage du lanceur #Neutron, des fissures sont apparues. Rocket Lab a indiqué que l'inter-étage a atteint la charge de qualification (~125 % de la charge en vol) et testé jusqu’à la défaillance, testant ainsi les marges de conception. Pas d'impact sur le calendrier de lancement du nouveau lanceur.

The science of spaghetti: Neutron scattering explains why gluten-free pasta falls apart

Using small angle neutron and X-ray scattering, researchers from the European Spallation Source and RWTH Aachen University have compared the nanostructure of gluten-free and normal spaghetti, finding that the kind with gluten is much more forgiving to varied cooking conditions.
