Astronomy Week 3 : Aliens

Astronomy Week 3:
Aliens

​Do you believe in 'aliens'?

​Yes!

​No....

'Extraterrestrial beings from another planet or star system'

The term "alien" in a scientific context refers to hypothetical life forms that could exist outside of Earth and did not originate on our planet

​What are aliens?

​So if aliens do/don't exist...what about UFO's?

To summarise...

​What is a UFO?

• UFO stands for 'Unidentified flying object'.

• However, the term UFO is not used by scientists anymore due to its association with 'extraterrestrials' or 'aliens'.

• The new term is 'UAP' which stands for Unidentified anomalous phenomena.

• UFO's are almost always explainable!

​Do you still believe in 'aliens'?

​Yes!

​No....

So what evidence is there? Really?

There are ongoing studies that suggest that 'life' in the form of bacteria or microbes might have existed at some point on other planets in our solar system.

​Basic Life forms

According to Nasa - there is absoluely ZERO evidence of 'aliens' or any intelligent life forms other than humans ever existing within our solar system.

​Intelligent Life

Basically...none

What about outside of our solar system?

The simple answer: We just don't know!


But have a listen to this...

Should we believe in aliens?

Maybe? Maybe not?

The answer is still unclear to science and astronomy. Whether you believe or not, there is no right answer - at the moment!
