Exploring extraterrestrial life

  • Alien, or extraterrestrial, is known as a living organism or being from outer space. [Merriam-Webster]

  • Recent developments have many questioning the possibility of extraterrestrials.

  • The Pentagon officially confirmed the existence of the Advanced Aerospace Threat Identification Program, a top-secret program dedicated to the study of UFOs. [The New York Times]

  • President Trump announced the Pentagon will start creating a "Space Force" equal to that of the U.S. military. [National Geographic]

  • President Trump expressed a desire to establish "dominance" in space, and not fall behind other countries like China. [The Boston Globe]



Discussing the possibility of extraterrestrial life can be a polarizing topic of conversation in America.


The United States can be viewed as one of the most backward countries in the world when it comes to alien exploration. Belgium, France, the U.K., and South American countries (like Chile) can be seen as more open and willing to discuss the topic. [Newsweek]

“Our scientists are scared of being ostracized, and our media is scared of the stigma..."

Indicators of life

In 2015, NASA announced strong evidence that liquid water flows on present-day Mars. Water is critical for life. [NASA]


Some scientists are using the Drake equation to help calculate the odds of life within the Milky Way. The Drake Equation suggests we will find life by 2040. [TIME]



Trappist-1 Planetary System

This recent discovery has many excited about the possibility of life. It is located approximately 39 light years away from Earth (close by galaxy standards– the Milky Way spans 100,000 light years), and contains similar planetary structures to Earth. []



Recent ramp-up

Some believe NASA's recent ramp-up efforts, such as TESS ("planet-hunting" satellite), the work of SETI (Search for Extraterrestrial Intelligence), and even President Trump's Space Force signals that the government has found something promising.


Rushing to conclusions

Astrophysicist Sara Seager believes “not knowing the origin of an object does not mean that it’s from another planet or galaxy." [NPR] Just because we do not know what is within the Navy pilot video does not mean it is an alien spacecraft.



Hostile environment

Professor Nick Lane cites the complex and statistically unlikely creation and survival of mitochondria (a building block of life) as a reason to doubt the existence of life on other planets that are more barren and hostile than Earth. [Futurism]



Clues, not facts

When looking into the numerous "sightings," some believe there are too many conflicting facts and variables. This leads many to consider these as"clues", or even debunked, as opposed to facts.


  • NASA and SpaceX launched TESS (Transiting Exoplanet Survey Satellite), planet-hunting Mission in April 2018. [NASA]

    • This 2-year project is to search for “exoplanets.” [NASA]

    • TESS will collect 27 gigabytes per day (6,500 song files) and send those back to Earth every two weeks. [NASA]

  • The Advanced Aerospace Threat Identification Program is officially listed as shut down. Yet, parts of the program are still classified. [The New York Times]
