Astrofysici bieden verklaring voor de oorsprong van een van de grootste satellieten van de Melkweg
Het satellietstelsel Crater II van de Melkweg bevindt zich op ongeveer 380.000 lichtjaar afstand van de Aarde in de richting van het sterrenbeeld Crater

#Darkmatter might be keeping an even darker secret
The prevailing idea regarding dark matter is the #colddarkmatter theory (CDM), which posits that dark matter is made up of low-velocity particles that do not interact with each other. Researchers compare a theorized behavior of dark matter to actual galaxies. Yu and his colleagues suggest that some dark force causes dark matter particles to smash into each other. This is Self-Interacting Dark Matter, or #SIDM.

暗黒物質が新しい理論で提案され、その存在についての説明が進展。自己相互作用暗黒物質(SIDM)理論が注目される。宇宙の観測データを用いた高解像度シミュレーション結果も取り上げられた。 #暗黒物質 #SIDM #理論
A #theory called "self-interacting dark matter," or #SIDM, proposes that #darkmatter #particles self-interact through a dark force, strongly colliding with one another close to the center of a #galaxy.
