Cornell University’s Loewentheil Collection of African-American Photographs has been fully digitized: it features 645 images of black lives from the 1860s through the 1960s, all of which eschew stereotypes: “One of the goals—both the Loewentheils in putting the collection together and ours in putting the digital collection online—is to push back against the predominance of material on African-Americans as enslaved people or working in menial jobs or other stereotypical situations … We wanted to show a broader swath of people in everyday settings.”

7 Facts That Will Make You Feel Very Small
nasa:
Earth, our home planet, is the fifth largest planet in our solar system and the only planet we know of where life exists. Even though Earth seems extremely large to us, it is actually a tiny spec in the vast expanse of the universe. Here are 7 space facts that will make you feel very small.
1. Our sun is one of at least 100 BILLION stars, just in the Milky Way. Scientists calculate that there are at least 100 billion galaxies in the observable universe, each one brimming with stars. There are more stars than grains of sand on all of Earth’s beaches combined.
In 1995, the first planet beyond our solar system was discovered. Now, thousands of planets orbiting sun-like stars have been discovered, also known as exoplanets.
2. The Milky Way is a huge city of stars, so big that even at the speed of light (which is fast!), it would take 100,000 years to travel across it.
3. Roughly 70% of the universe is made of dark energy. Dark matter makes up about 25%. The rest — everything on Earth, everything ever observed with all of our instruments, all normal matter adds up to less than 5% of the universe.
4. If the sun were as tall as a typical front door, Earth would be the size of a nickel.
5. The sun accounts for almost all of the mass in our solar system. Leaving .2% for all the planets and everything else.
6. Edwin Hubble discovered that the Universe is expanding and that at one point in time (14 billion years ago) the universe was all collected in just one point of space.
7. Four American spacecraft are headed out of our solar system to what scientists call interstellar space. Voyager 1 is the farthest out — more than 11 billion miles from our sun. It was the first manmade object to leave our solar system. Voyager 2, is speeding along at more than 39,000 mph, but will still take more than 296,000 years to pass Sirius, the brightest star in our night sky.
