Defining the Habitable Zone
What makes Earth the perfect home for life
as we know it? Students in this activity
explore the orbital characteristics a
planetary home needs to support Earth-like
life forms

What is Astrobiology?
Astrobiology is the study of
life in the universe. It
provides a biological
perspective to many areas of
NASA research, linking
such endeavors as the search
for habitable planets,
exploration missions to
Mars and Europa, efforts to
understand the origin of life,
and planning for the future
of life beyond Earth.
Astrobiology Goals:
Astrobiology addresses three basic questions,
which have been asked in some form for
generations. Astrobiology is exciting today
because we have the technology to begin to
answer these fundamental questions:
• How does life begin and develop?
• Does life exist elsewhere in the universe?
• What is life's future on Earth and beyond?

Activity: Stellar Sorting
Sort your star cards by:
 Distance from Earth
 Temperature
What pattern emerges?
Which stars will support
Earth-like life?
How is the habitable
zone effected by star
type?
Activity: Extra Solar Planets
In addition to having just the
right kind of star, a planet
must also have just the
right mass and be just the
right size to support life!
 Mass - .5 - 10 Me
 Radius - .8 - 2.2 Re
Which extra solar planets
might be JUST RIGHT?
