How has Twitter
affected my enthusiasm for Space?  That is a really good question,
especially for those of us who thought we couldn’t be any more

Twitter does something that no astronomy/Space forum, chatroom,
website, or club can ever do with such efficiency; and that is to bring
a diverse global community together with both immediacy and personal
selectivity.  With Twitter, we are able to find specifically those
people who share our passion and we can spontaneously share whatever we
want, whenever and from wherever we want.  For space enthusiasts, this
means a wealth of new knowledge as we share resources, catching the
latest press briefings and conferences as they occur, and even communicating directly
with various Space missions.  We are not limited by profession,
location, or experience; rather, we are drawn together for our
diversity of those very things.

Though this certainly is enough, it is not the whole of how Twitter
has affected my enthusiasm for Space.  The whole comes in an outreach
potential like none that has ever before been known – and outreach is
exactly what most excites me about Space and astronomy.  I want every
person on this planet to look up and to know that we are but one part
of something much greater; to consider the possibilities that exist
only in reaching beyond this world to explore that science which
defines our very existence; and to realize that it is through that
exploration, that greater understanding of our place in the Universe,
that we can best answer the questions about bettering the world we live
in, right here, right now.

Once upon a time, distance shrouded the Universe from our view. 
Galileo’s telescope took those first steps in shortening that
distance.  Today, that very distance is not only shortened, it is
brought down to Earth by Space-based observatories, like Hubble and
Kepler.  Twitter is the Hubble of global communication, not only in
drawing together a worldwide Space community, but in bringing Space to
that community and more.

When I share some Space-related news on Twitter, when I retweet some
the time of an astronomy conference, when I post links for my humble
images of the night sky, I’m not simply sharing with my Twitter
friends.  I’m hoping that someone else out there, some one who never
realized that they can see the planet Jupiter from their backyard, or
never even knew that we have discovered planets beyond our solar
system, will somehow see my tweet, walk outside, and Look Up.  And that
is how Twitter has affected my enthusiasm for Space.
