Today is June 15. #OTD in 1667, French physician Jean-Baptiste Denis attempted something no one had ever done before: a blood transfusion. He transfused blood from a sheep into a teenage boy suffering from a severe fever, fully documenting the procedure’s signs and symptoms.

CINQUE GALASSIE IN POSA, RITRATTE DA HUBBLE Buongiorno a tutti, con questa immagine che non esito a definire pazzesca, ripresa dal telescopio spaziale Hubble. Il gruppo di isole cosmiche qui ritratto è definito Hickson Compact Group 40 e comprende tre galassie a spirale, una lenticolare e una ellittica. Pensate che questa zona di cielo è così affollata che potrebbe rientrare tutta in una regione di spazio inferiore al doppio del diametro del disco stellare della Via Lattea, ovvero all'incirca 210.000 anni luce! Noto anche come Arp 321, questo bellissimo ammasso è situato nella costellazione dell'Idra, a circa 300 milioni di anni luce dalla Terra. Un'autentica ed incredibile meraviglia, non credete anche voi? 😍 Credits: NASA, Hubble.

Today June 13. #OTD in 1831 physicist James Clerk Maxwell was born. Formulated electromagnetic theory. Regarded as scientist of 19th century who had the greatest influence on 20th-century physics, and ranked with Newton and Einstein for fundamental nature of his contributions.

The prominent spiral galaxy on right side of this @NASAHubble image is NGC 1356; the two apparently smaller spiral galaxies flanking it are LEDA 467699 (above it) and LEDA 95415 (very close at its left) respectively; and finally, IC 1947 sits along the left side of the image.

I love this portrait of my home town.
New York City is 9% Muslim and has a Muslim mayor, which scares a lot of people, most of whom don't live here. This afternoon on the train ride home (air-conditioned, thank god), I see an Arab-looking girl in a headscarf and a long, conservative dress chatting animatedly with her friend, a Chinese-American girl (New York is 15% Asian) in shorts and a tank top. As far as I can tell, neither one of them mentions Sharia or jihad; instead, they seem to be looking at pictures and arguing about which boy (I assume) looks cutest. They address each other as "bro." A Caribbean woman enters the car, chatting on her phone. She is heavyset and middle-aged, with dyed orange hair. She sits down and gets off the phone as the train leaves the station. Next stop, another middle-aged black woman, more conservatively dressed, sits down next to her. She's reading "Kin" by Tayari Jones (an Oprah Book Club recommendation). (New York is 20% black, about 1/3 of those from the Caribbean.) At the same time, a white father and daughter come in. People scrunch aside so they can sit together. He starts to read a picture book to her, but after a bit, she insists she can read on her own. He pulls out his own book. (New York is 31% non-Hispanic white.) A few stops later, a Hispanic man gets on the train with a guitar. Oh no! But it turns out he's pretty good (often not the case), I enjoy his plaintive ballads about love or something. I give him a dollar, and he says "Gracias." (New York is 29% Hispanic.) There's one annoying drunk dude, an older white guy. I assume he's drunk and not crazy or homeless because his clothes are nice and he's clutching a phone, but he seems on the verge of passing out, repeatedly bending over slowly until another lurch of the train wakes him up and he straightens. The dad with the daughter looks alert and peeved. Understandably! I get out at my stop, along with the drunk guy, but I take a different set of stairs to avoid dealing with him. Then a short walk from the station in the sweltering heat, with a brief stop at my Yemeni bodega (more Muslims!). Finally, I pass a Cuban-run barbershop with no one getting a haircut, and a couple sitting outside (the owners, I assume) listening to salsa. I get home and turn on the damn AC, safe once more from assault and/or bad serenades.

Today is June 11. #OTD in 1910 oceanographer Jacques Cousteau was born. He co-invented the first successful open-circuit self-contained underwater breathing apparatus (SCUBA), called the Aqua-Lung, which assisted him in producing some of the first underwater documentaries.

Nine years ago today my colleagues and i shot what likely remains the highest resolution ground based image of Saturn ever taken. We used the 1m F/17 Cassegrain telescope at Pic du Midi Observatory nestled almost 10,000ft altitude in the French Pyrenees. Many rarely seen details were captured, such as the multiple fine ringlets within the C-ring. The narrow Encke division was captured around the entire ring system. This division is only 200 miles wide spanning less than 0.1 arc seconds in angular width. Atop the globe of the planet the famous hexagon shaped feature is clearly seen - a fast moving jet stream that encircles the polar region. Saturn's rings will not appear this open again until 2031 - perhaps by which time an even better ground based image will have been taken!

Astronomers may have found one of the closest supernova remnants to the supermassive black hole at the center of our Milky Way galaxy. It's expanding at about 3.2 million kilometers per hour (2 million mph) and is at least 1,700 years old. 💥More: s.si.edu/sgrc26

Many people (even physicists) are surprised to learn that the universe doesn’t conserve energy, as @neiltyson pointed out in a recent podcast. Even most physicists who know this don’t know who first figured it out. Her story is here: amzn.to/3YZZB4W #history #physics

I was blithely walking in Central Park, not really paying attention when this Northern Flicker hopped out of my way! She stuck around long enough for a nice profile pic! 😍😍😍 #Flicker #CentralPark #birdcpp
