have you ever done the Hula? ]]>
about some really cool observatories in Hawaii. ]]>
distant objects look larger and nearer. ]]>
use telescopes to look out into space. ]]>
the observatory is located here on Earth. ]]>
the observatory is in outer space, ]]>
that orbits the Earth ]]>
of our universe. ]]>
all over the globe, ]]>
very special Earth-based observatories in Hawaii. ]]>
hundreds of small islands in the Pacific Ocean. ]]>
on the big island of Hawaii ]]>
that means “white mountain.” ]]>
to erupt anymore. ]]>
from several different countries ]]>
Earth-based telescopes of different kinds. ]]>
through Earth’s atmosphere. ]]>
and may appear fuzzy. ]]>
as well, making faraway light hard to see. ]]>
on Mauna Kea ]]>
from most of the pollution in the sky. ]]>
are fewer particles to scatter the light. ]]>
covering the summit. ]]>
to look into outer space ]]>
there is less light pollution. ]]>
an extremely dark sky to observe ]]>
use optical telescopes, ]]>
in many different varieties. ]]>
all the time. ]]>
of light that comes to us from the sun. ]]>
on before you go outside in the sun? ]]>
from an ultraviolet light. ]]>
a kind of light. ]]>
you might have had an X-ray done. ]]>
can actually penetrate into your body ]]>
with your bones. ]]>
are what an optical telescope would see. ]]>
more powerful. ]]>
visible light from faraway objects in space. ]]>
with our naked eyes. ]]>
like stars seem brighter ]]>
so we can look ]]>
than ever before. ]]>
really big telescopes ]]>
and link them together by computer. ]]>
is the Gemini North Telescope. ]]>
is located in Chile. ]]>
was so big ]]>
on the Earth and have it survive. ]]>
the telescopes together, ]]>
by all those miles function as one telescope. ]]>
to link them up like that, ]]>
like our eyes see. ]]>
don’t they? ]]>
and then closing the other ]]>
by a distance ]]>
with our telescope. ]]>
are getting so powerful ]]>
and stars as clear ]]>
use a mirror, ]]>
in order for the images not to come out fuzzy. ]]>
that don’t give you fuzzy pictures. ]]>
one giant mirror, ]]>
so they make one big mirror. ]]>
by a computer. ]]>
of a really big mirror, ]]>
when you are looking ]]>
the light to get rid of the fogginess ]]>
are now getting even better ]]>
that astronomers ]]>
they build these giant observatories. ]]>
like the ones in Hawaii, ]]>
that make it difficult to look into space. ]]>
looked in a grass skirt, huh? ]]>
