Pls don't DM me unless we've chatted before on here. Interests: cosmology, astronomy, other sciences, history, wildlife. Rusty polyglot. GRB090423 was the most distant gamma ray burst known when I first started on socmed. Profile (Sputnik 1) and banner (the Sun) photos are by me. I rarely boost images that don't have Alt Text. I boost The Vagina Museum posts; please don't be offended - it's good to learn. I check your bio & TL to decide whether I follow back.
