Reposted from @nasa Tonight, count the stars and remember a trailblazer. We're saddened by the passing of celebrated mathematician Katherine Johnson. Her spirit and determination helped lead us into a new era in space exploration, and for that we are grateful. Once a "human computer", she famously calculated the flight trajectory for Alan Shepard, the first American in space. And when we began to use electronic computers for calculations, astronaut John Glenn said that he’d trust the computers only after Johnson personally checked the math. Her calculations proved as critical to the success of the Apollo Moon landing program and the start of the Space Shuttle program, as they did to those first steps on the country's journey into space. We celebrate her 101 years of life and honor her legacy of excellence that broke down racial and social barriers. What does Katherine Johnson’s legacy mean to you?

Dang Shame!
I'm about to sue the league for collusion

The holiday has since grown to a giant celebration in multiple cities internationally and celebrates religion, culture food and history. (📷 Getty Images) - #regrann - #regrann
@Regrann from @1_christ_loved - Not much of a beer man myself...but cheers to you that are 🍻🍻🍻 @Regrann from @history - It’s #InternationalBeerDay ! A day for beer lovers everywhere to raise a toast and celebrate this historic beverage! Beer has been around for possibly millennia. The world’s first fermented beverages most likely emerged alongside the development of cereal agriculture some 12,000 years ago. In fact, some anthropologists have argued that these early peoples’ insatiable thirst for hooch may have contributed to the Neolithic Revolution by inspiring new agricultural technologies. The earliest known alcoholic beverage is a 9,000-year-old Chinese concoction made from rice, honey and fruit, but the first barley beer was most likely born in the Middle East. While people were no doubt imbibing it much earlier, hard evidence of beer production dates back about 5,000 years to the Sumerians of ancient Mesopotamia. Beer consumption also flourished under the Babylonian Empire, but few ancient cultures loved knocking back a few as much as the Egyptians. Workers along the Nile were often paid with an allotment of brew, and everyone from pharaohs to peasants and even children drank beer as part of their daily diet. Many of these ancient beers were flavored with unusual additives such as mandrake, dates and olive oil. More modern-tasting libations would not arrive until the Middle Ages, when Christian monks and other artisans began brewing beers seasoned with hops. Drink up! #beer
@Regrann from @history - On #ThisDayinHistory 1967, Thurgood Marshall becomes the first African American to be confirmed as a Supreme Court justice. He would remain on the Supreme Court for 24 years before retiring for health reasons, leaving a legacy of upholding the rights of the individual as guaranteed by the U.S. Constitution. After graduating from Lincoln University in 1930, Marshall sought admission to the University of Maryland School of Law, but was turned away because of the school’s segregation policy, which effectively forbade blacks from studying with whites. Instead, Marshall attended Howard University Law School, from which he graduated magna cum laude in 1933. (Marshall later successfully sued Maryland School of Law for their unfair admissions policy.) As a lawyer, Marshall distinguished himself as one of the country’s leading advocates for individual rights, winning 29 of the 32 cases he argued in front of the Supreme Court, all of which challenged in some way the ‘separate but equal’ doctrine that had been established by the 1896 landmark case Plessy v. Ferguson. The high-water mark of Marshall’s career as a litigator came in 1954 with his victory in Brown v. Board of Education of Topeka. In that case, Marshall argued that the ‘separate but equal’ principle was unconstitutional, and designed to keep blacks “as near [slavery] as possible.” In 1961, Marshall was appointed by then-President John F. Kennedy to the U.S. Court of Appeals for the Second Circuit, a position he held until 1965, when Kennedy’s successor, Lyndon B. Johnson, named him solicitor general. Following the retirement of Justice Tom Clark in 1967, President Johnson appointed Marshall to the Supreme Court, a decision confirmed by the Senate with a 69-11 vote. #ThurgoodMarshall #SCOTUS #history #legalhistory #ushistory
Are you ready to see unprecedented, detailed views of the universe from the James Webb Space Telescope, the largest and most powerful space observatory ever made? Scroll down to see the first full-color images and data from Webb. Unfold the universe with us. ✨
This landscape of “mountains” and “valleys” speckled with glittering stars, called the Cosmic Cliffs, is the edge of the star-birthing Carina Nebula. Usually, the early phases of star formation are difficult to capture, but Webb can peer through cosmic dust—thanks to its extreme sensitivity, spatial resolution, and imaging capability. Protostellar jets clearly shoot out from some of these young stars in this new image.
The Southern Ring Nebula is a planetary nebula: it’s an expanding cloud of gas and dust surrounding a dying star. In this new image, the nebula’s second, dimmer star is brought into full view, as well as the gas and dust it’s throwing out around it. (The brighter star is in its own stage of stellar evolution and will probably eject its own planetary nebula in the future.) These kinds of details will help us better understand how stars evolve and transform their environments. Finally, you might notice points of light in the background. Those aren’t stars—they’re distant galaxies.
Stephan’s Quintet, a visual grouping of five galaxies near each other, was discovered in 1877 and is best known for being prominently featured in the holiday classic, “It’s a Wonderful Life.” This new image brings the galaxy group from the silver screen to your screen in an enormous mosaic that is Webb’s largest image to date. The mosaic covers about one-fifth of the Moon’s diameter; it contains over 150 million pixels and is constructed from almost 1,000 separate image files. Never-before-seen details are on display: sparkling clusters of millions of young stars, fresh star births, sweeping tails of gas, dust and stars, and huge shock waves paint a dramatic picture of galactic interactions.
WASP-96 b is a giant, mostly gas planet outside our solar system, discovered in 2014. Webb’s Near-Infrared Imager and Slitless Spectrograph (NIRISS) measured light from the WASP-96 system as the planet moved across the star. The light curve confirmed previous observations, but the transmission spectrum revealed new properties of the planet: an unambiguous signature of water, indications of haze, and evidence of clouds in the atmosphere. This discovery marks a giant leap forward in the quest to find potentially habitable planets beyond Earth.
This image of galaxy cluster SMACS 0723, known as Webb’s First Deep Field, looks 4.6 billion years into the past. Looking at infrared wavelengths beyond Hubble’s deepest fields, Webb’s sharp near-infrared view reveals thousands of galaxies—including the faintest objects ever observed in the infrared—in the most detailed view of the early universe to date. We can now see tiny, faint structures we’ve never seen before, like star clusters and diffuse features and soon, we’ll begin to learn more about the galaxies’ masses, ages, histories, and compositions.
These images and data are just the beginning of what the observatory will find. It will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.
