Enlightening visit to “the Dark Side” in the Gran Sasso 🇮🇹 National Laboratory deep inside an Abruzzo mountain today - meeting lots of talented scientists including many from 🇬🇧 universities researching the approx 27 per cent of the universe that is dark matter…🇮🇹🇬🇧🇮🇹🇬🇧
Hello hello 👋 #IWD2023 is nearly here, and so are companies' cut-and-paste platitudes. And once again we're bringing you the data to see whose support for #InternationalWomensDay is genuine, and who's still got work to do.
Here's a reminder of how it works ⬇️ (1/8)
#TolkienReadingDay The Black Land in "Lord of the Rings" lends its name to the north pole region of my largest moon. #Charon's distinctive red-brown cap, called Mordor, is 475 km (295 mi) in diameter & resembles the shape of Sauron's realm.😃📖#Space https://t.co/Ie4JMiP2BJ

#OTD 3-23-2178, I will complete my 1st revolution around the Sun since discovery. You are cordially invited to join the festivities as I ring in the new Plutonian year. Please RSVP by March 23, 2177. And please invite a friend - the more the merrier!🤩🥳https://t.co/Ie4JMiP2BJ
Fritz Zwicky is often credited for coining the term 'dark matter' but that's not quite true: the term had been in use for *decades* when he published his famous 1933 paper, and he was well aware of that. A #Thread on the early history of #darkmatter https://t.co/K1HT1e1SsL
Venetia's grandfather passed her name suggestion on to an astronomy professor friend of his, Herbert Hall Turner, who then sent a telegram to Lowell Observatory. It was perfect timing since everyone was consumed with the question of what to name the new planet.🤩#Pluto#Space
#WhatsInAName#OTD 3-14-1930 Venetia Burney, an 11 yr old British girl who loved planets & books, suggests the name #Pluto for the new 9th planet. The name has it all: connections to mythology, dark undertones, & the initials of Percival Lowell. Perfect!😊https://t.co/Ie4JMiP2BJ
Though Clyde Tombaugh discovered me 2-18-1930, the Lowell Observatory director, V.M. Slipher, decided to postpone announcing the discovery until #OTD 3-13-1930 so results could be verified. In this authentic memo ⬇️Slipher details the decision. Reminds me a bit of modern times😄
#TRISEP2021 features lectures by leading experts in the field of particle physics and is designed with ample time for group work, problem-solving, and discussions with the speakers.
