Though he may be gone, after 26 years, Carl Sagan is still an inspiration to many
It's been 26 years to
the day since the world lost the great Carl Sagan. A man who created
a "message to the universe” on a gold record to be carried by the Voyager Interstellar Mission, helped discover that Venus is warmed by
greenhouse gases and made turtlenecks a staple.
Though it has been over two
decades since Sagan died in 1996 from bone marrow disease, we are
still thankful for the lessons he taught us and the legacy he left behind. In a
2014 Smithsonian story, Sagan's wife, Ann Druyan, recalled a
porter from Union Station in Washington, D.C., refusing to accept
payment from Sagan, saying, "you gave me the universe." And Sagan did just that with
his 1980s series, Cosmos.
Sagan taught us many valuable
lessons about the universe and even made some uncanny predictions about the
future. Here are four things we thank him for.

Two of today's most popular
scientists, Bill Nye and Neil deGrasse Tyson, each claim Sagan as their inspiration.
How would you like to have Carl Sagan as your astronomy professor? For Nye,
this was reality. While Nye was studying at Cornell University in the late 70s, Sagan was his astronomy professor. Nye learned much about the universe from Sagan, saying that his lectures were like Cosmos episodes. At his 10-year class reunion
in 1987, Nye told Sagan about his idea for a TV show that he wanted to gear
towards children. Sagan advised him to “focus on pure science, kids resonate with

accolades (including
accolades (including 19 Emmy awards) and inspiring a generation of future

the surface of Venus ranged from 300-400°F, proving that Venus was heated due to a large amount of carbon dioxide in the atmosphere trapping the heat from the sun.
this inspired quote from Sagan:
Nye later went on to be the CEO
of The Planetary Society, an organization founded by Sagan. Now, Nye gets to
continue part of Sagan’s legacy. If you grew up loving Bill Nye’s show, you owe
much of that love to Carl Sagan.
Tyson met Sagan when he was
17, after Sagan invited him to visit Cornell one snowy Saturday in
December. December 20, 1975, to be exact. Twenty-one years before his
death. Sagan was impressed by Tyson’s application to
Cornell University and hoped to recruit him to join the
school. Sagan even gave Tyson his home phone number in case the bus couldn’t make it
through the snow. He offered up his home to Tyson. Tyson would go on to
study at Harvard, but he never forgot the impact Sagan’s gesture had on his life.
“I already knew I wanted to
become a scientist, but that afternoon I learned from Carl the kind of person I
wanted to become,” Tyson said in a interview with Insider.
Tyson is now regarded in a similar way that Sagan was. The popular astrophysicist appears regularly on late-night talk shows and even hosted Cosmos: A Spacetime Odyssey, the 2014 series a follow-up to Sagan’s own series.
Sagan Taught Us
to Cherish Our Home
In 1962, Mariner 2 made its way to Venus. Venus was once thought to have a climate similar to that of Earth’s tropical regions. But the reports from Mariner 2 determined that
Later on, as
technology advanced, it was found that the surface of Venus was closer to
900°F.
In 1985, Sagan testified in
front of Congress on the impact of climate change on Earth.
He discussed how burning fossil fuels and using aerosol led to an increase in carbon dioxide in our atmosphere. His warning was not unlike those we hear from climate scientists today, especially when it comes to the melting of the polar ice caps and the rise of sea levels. Sagan realized that the major solution, which would be cutting off the use of all fossil fuels, wasn’t something that would fly. So, he also offered alternative solutions such as solar power.
“This is an intergenerational
problem. If we don’t do the right thing now there are very serious
problems that our children and grandchildren will have to face," Sagan
predicted during his testimony. Watch his testimony here.
He Helped us Understand the Universe Like No One Had Before
When Sagan’s 13-episode Cosmos: A Personal Voyage aired on PBS in 1980 it quickly
became the network’s most-watched series and held that top spot for a
decade. Sagan co-created the series with his future wife,
Ann Druyan, among others. They wanted to create a show that could help anyone
understand the universe. They did so without having to “dumb”
anything down. Sagan and the creators respected the audience they
had, and the audience responded well to it. Perhaps the reason Cosmos performed so well was the fact that
Sagan had to work hard to understand things that seemed to come so easy
to others.
In 2013, Sagan’s papers arrived
at the Library of Congress and the archive was opened for
researchers a few months later. Among the pages was this quote:
“I think I’m able to
explain things because understanding wasn’t
entirely easy for me. Some things that the most brilliant students were able to
see instantly I had to work to understand. I can remember what I had to do to
figure it out. The very brilliant ones figure it out so fast they never see the
mechanics of understanding.”
Cosmos was an inspiration to so
many – not just people who wanted careers in science. It was meant
for all to understand the universe they live in a little bit better.
He Challenged Us to Live
Purposeful Lives
On February 14, 1990, Voyager 1, carrying the “message to the universe” on its way to interstellar travel, turned at the suggestion of Sagan took a photo of Earth. Though it was 4 billion miles away, Voyager 1 was able to capture a very faint image of our planet Earth, the famous Pale Blue Dot. From that image, we get
“That’s here. That’s home. That’s us. On
it, everyone you love, everyone you know, everyone you have ever heard of,
every human being who ever was, lived out their lives...[E]very king and
peasant, every young couple in love, every mother and father, hopeful child,
inventor and explorer, every revered teacher of morals, every corrupt
politician, every superstar, every supreme leader, every saint and sinner in
the history of our species lived there–on a mote of dust suspended in a
sunbeam.”
If Carl Sagan has taught us
anything, it’s to stay curious. It was curious minds that dared to reach into space and
explore the vast reaches of the universe. Curious minds that brought us
the realization that we as a species are only here because the stars
aligned in just the right way so that life on Earth could be possible. He was a
pioneer in modern science and inspired all of us to wonder what other
possibilities may be out there.
“Curiosity and the urge to
solve problems are the emotional hallmarks of our species.”
