At the turn of the 20th century, astronomy got a serious glow-up. An influx of money and scientific advancements led to building bigger, better telescopes at newly-founded observatories across the country. Astronomers could see farther than ever before, and this led to a debate about exactly what they were seeing. Were these nebulous, fuzzy-looking discs in the sky part of the Milky Way? How big is our universe? On today’s episode, we’re telling the story of how the work of many astronomers contributed to a complete redesign of how big we know our universe to be and what we think it looks like.

Society & Culture

AirSpace will be back in two weeks with brand new epsiodes. In the meantime, enjoy this episode from our friends at the podcast, This is Love.

When twin rovers named Spirit and Opportunity landed on Mars twenty years ago, they were only supposed to last 90 Martian days. But years passed, they were still alive, and engineers kept taking care of them. “I remember telling myself, ‘Please don’t die, Opportunity. Please don’t die.’”

While we get Season Nine ready for you, we turned to our friends at Sidedoor to bring you a story of running and running and running and running…in Space! We’ll let them take it from here:

Until the 1970s, women were barred from competing in U.S. marathons because of the belief that the "violent movements" of running would wreak havoc on their reproductive system, "thus defeating a woman’s true purpose in life, i.e., the bringing forth of strong children." Through a series of steps, stumbles—and one epic tackle—running pioneers like Roberta "Bobbi" Gibb and Kathrine Switzer blazed the trail for women marathoners who followed, including Sunita Williams—the first person to run the Boston Marathon in space!

You’ll have new AirSpace episodes soon, but since they may have found Amelia Earhart’s plane(!!!) we thought we’d revisit our episode on her and Eleanor Roosevelt’s somewhat unlikely friendship.

On a spring evening in 1933, Amelia Earhart took first lady Eleanor Roosevelt on a joyride. Imagine two women—dressed for dinner at the White House (white gloves and all)—stealing away from 1600 Pennsylvania Ave to pilot and co-pilot a nighttime flight to Baltimore. On this episode of AirSpace, we’re detailing the high-flying friendship of these two women – from their shared background as social workers to their mutual love of flight and advocacy of women’s empowerment and social justice. Amelia and Elanor took the business of being role models seriously, leading by example and using their influence to elevate important societal issues. Talk about an influencer power couple!

Thanks to our guests who helped us contextualize their history and friendship – biographers Allida Black and Susan Butler.

AirSpace Revisited - With a Little Help From My Friends

As we look forward to the upcoming total solar eclipse over North America, AirSpace is looking back in time to a much much older eclipse. In 1142 a total solar eclipse with much the same path as the one coming up April 8. It was also the sign in the sky the Seneca needed to join the Haudenosaunee Confederacy, a representative democracy that would govern six tribes below Lakes Erie and Ontario. Before a 1997 journal article, Western Historians insisted the eclipse that decided the Seneca happened much later in the 15th or 16th century. We talk to one of the authors of the paper about the tradition, evidence, and astronomy behind the more accurate date.

When the Sun Went Out

Did you know that it takes the Earth 365-ish days to orbit the sun? It’s that ‘ish’ that makes February 29 a thing every four years. We talk to one of the Museum’s astronomy educators to get the low down on Leap Day.

Thanks to Astronomy Educator Shauna Brandt Edson for joining Emily for this episode.
