Does Life Exist On Other Planets?

Science fiction writers continue to chip away at the secrets contained within the universe and often speculate on the possibility of life on other worlds and what it might look like. So who—among us Earthlings—thinks life on other planets exists?

Chances of finding life on other planets remains unknown, but research astronomer, Shawn Domagal-Goldman, said, “I want it to be there. I’ll be planning a party if we find it.” He works at  NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and co-leads a team of exoplanet hunters.

Another NASA representative said,  

Unless we get lucky, the search for signs of life could take decades. Discovering another blue-white marble hidden in the star field, like a sand grain on the beach, will probably require an even larger imaging telescope. Designs are already underway for that next-generation planet finder, to be sent aloft in the 2030s or 2040s.

Earth’s Past

Scientists are constantly searching for a planet like Earth. However, Earth as we know it today looks far different from outer space than it did billions of years ago.

Therefore, it is possible life does exist on other planets, but as grand as our telescopes are they might not be sufficient enough to detect life. And though some of the exoplanets found look promising, just like the artwork of Earth, from a distance these ever changing exoplanets—if not now perhaps in the future—may become capable of producing life.


On Earth to sustain life, we must have water and elements such as carbon, nitrogen, oxygen, phosphorous, and sulfur. We also need sources of energy. Surprisingly, these ingredients for life appear to be almost everywhere scientists have looked in outer space. But even with our advanced technology and even bigger, far-reaching telescopes like the James Webb, the cosmos remains silent. 

Our question, does life exist on other planets, remains unanswered. And we’re not talking about intelligent life but any type of life down to the smallest unit of life—a single cell.

A Poll

When I polled the sci-fi google+ community, 380 science fiction lovers responded to the following question.

QUESTION: What is your vote for existence of life on other planets?


  • Definitely 79%
  • Maybe 13%
  • Looking is a waste of time and money 5%
  • Don’t think so 4%

An overwhelming majority of sci-fiers believe in the existence of life on other planets. Not a surprise. What is surprising is that 5% think it’s a waste to look and another 4% don’t think there is even the slightest possibility of life outside Earth.

What Experts Say

If we do find life, what will it be?

In 2017, the then NASA’s chief scientist, Dr. Ellen Stofan predicted, we’ll find signs of alien life within 10 years.

Dr. Ellen Stofan, Chief Scientist, National Aeronautics and Space Administration at National Air and Space Museum.

“I think we’re going to have strong indications of life beyond Earth within a decade, and I think we’re going to have definitive evidence within 20 to 30 years,” she said on April 7, 2015 in Washington during a panel discussion focused on the space agency’s efforts to search for habitable worlds and alien life.

Jeffrey Newmark, NASA’s interim director of heliophysics, agrees with Stofan.  “It’s definitely not an if, it’s a when,” he says.

Both of these statements echo remarks made by NASA astronomer Kevin Hand, who a year earlier in a panel discussion said. “I think in the next 20 years we will find out we are not alone in the universe.” 

The passing of those 20 to 30 years since 2015, approaches faster than any of us wanted or expected. As time races forward, perhaps we will have answers in the near future.

4 Reasons Why Life on Other Planets Is Possible

  • Water is turning up on more planets.
  • The sheer vastness of the universe. “It’s highly improbable in the limitless vastness of the universe that we humans stand alone,” Charles Bolden, NASA Administrator,  said.
  • The discovery of more Earth-like planets gives us the prospect that life elsewhere is possible.
  • The existence of extremophiles on Earth proves life finds a way.

What is your vote? Do you think there’s life on other planets—any kind of life even microbial?

Life finds a way huh? I think you’ve been at the Jurassic park again, or maybe just having coffee with Mr Goldblum. Also I’m thinking that the 4% might be the same guys who think God buried dinosaur bones to mess with us.
Got lost down the rabbit hole of googling water bears last week after one of your tweets, got them on the brain now, so thanks 😉
I take it that you’re also pro Pacific Rim 2?
Loving the mission statement 🙂

Myk, what can I say. For someone like me, whose first exposure to sci-fi was Godzilla, Jurassic is just so…so…mind exploding. Yes. Love it! And Pacific Rim and Battleship. PR and B are two movies that never received the accolades they deserved.

Go Tardigrades!
Wait God didn’t bury the dino bones??
Seriously, He didn’t?

Thank you for the fly-by and comment. Think I’ll toggle on over to and see what you are up to.

(Glad you like the mission statement.)
