About a quarter of a bajillion years ago, I featured American astronomer Maria Mitchell.
Today's famous birthday, born on this date in 1847, was another American astronomer. Like Mitchell, Mary Watson Whitney was a woman who managed to get a much better education than most women and who managed to do valuable work in a field completely and almost totally dominated by men: astronomy.
It turns out, Whitney met and was taught by and worked with Mitchell!
Born in Massachusetts, Mary Whitney had a father with enough wealth that she was able to get a great education compared with most girls and women. After attending a local school, Whitney had a private tutor for a year and then went to Vassar College, where Mitchell was a professor.
Whitey obtained Bachelor's and Master's degrees from Vassar, and she was able to attend some courses in Harvard (only as a guest - women weren't allowed to attend Harvard for credits then!). She went to Switzerland for three more years of study, although she apparently didn't obtain a PhD.
When Whitney returned to the U.S., she became a high school teacher. However, she soon became an assistant to Mitchell at Vassar and, when Mitchell retired, became a professor and the director of the observatory.
Whitney's astronomical research dealt with double stars, variable stars, asteroids, and comets; and under her direction more than 100 articles were published at the observatory.

| Double stars are stars that circle around one another. |
 |
| Variable stars change in brightness. Some variables change in cycle through expansion and contractions, swelling and shrinking, with the temperatures and brightness cycling along with the size. |
 |
| Asteroids are chunks of rock ranging in size from 600 miles (1,000 km) across to particles of dust; they circle the Sun, many of them in the "asteroid belt" located between Jupiter and Mars. |
 |
| Comets are bodies made of ice and dust that circle the Sun in long elliptical orbits; when near the Sun, a "tail" of gas and dust particles point away from the Sun. |
