Looking up at the night sky, you won’t see the sun
and all the planets that belong to our solar system,
but you may see the moon and some stars. Long ago,
people thought the stars made patterns in the sky that
looked like people, animals, and other things. These
groups of stars were called constellations.
Today there are 88 constellations.
Ursa Major or the “Great Bear”
is easily one of the best-known
constellations. Many ancient
peoples saw a bear in this
group of stars.
Some Native American legends say
that “the giant bear has three hunters
chasing it.” Inside Ursa Major, you can
find the Big Dipper. The Big Dipper is
a group of stars that looks like a cup
with a long handle.
Like Ursa Major, Orion is also
a famous constellation. In a Greek
myth, Orion was a great hunter.
He was killed when he stepped on
a scorpion.
The Greek gods felt sorry for Orion.
They put him and his dogs in the
sky as constellations. Then they put
all the animals he hunted near him.
They placed the scorpion farther away
so Orion wouldn’t be hurt by it again.
The main star of this constellation
marks Orion’s left shoulder and is
called Betelgeuse ( BEE – tuhl – jewz ).
Compared to Betelgeuse, most stars
look dim.
How bright stars appear depends on their distance
from Earth, how large they are, and their different
temperatures, or how hot they burn.
Scientists can use powerful telescopes to observe
the stars closely and find out more about them.
Scientists know that Betelgeuse
is 630 times larger than our sun
and shines 60,000 times brighter.
It is one of the largest stars anywhere
in the night sky, and probably one of
the most fascinating to study.
