Our Galaxy
Distance from the Sun to the Galactic Center: 25,000 light years
We live in the disk of the Milky Way Galaxy which has a
diameter of about 100,000 light years. The Galaxy
Garden in Kona is an outdoor scale model of the Milky
Way, mapped in living plants and flowers and based on
current astrophysical data. It is 100 feet (30 meters) in
diameter.

Not all galaxies look pretty and symmetric. When they
do not, astronomers use the term “irregular" to describe
them. IC 10 is one such galaxy. Astronomers study it in
order to understand how stars evolve. IC 10 is also a
member of a cluster of galaxies called the Local Group,
which includes the Milky Way and Andromeda Galaxies.

MGC 2403 is a spiral galaxy whose mass is about half
of our Milky Way Galaxy. In the spiral arms we see
active star-forming regions in pink, clusters of young
stars in blue, and gas and dust within the galaxy in dark
regions.

Supernova 1993J located in M81 galaxy was discovered
March 28, 1993, by an amateur astronomer in Spain.
Astronomers observed the supernova from May 17,
1993 (top-left) to February 25, 2000 (bottom-right). We
can see a shell-like radio structure which has expanded
for seven years with circular symmetry.
