Naked Eye Wonders NZ Time: 10:34am NZST -Monday, April 26, 2004

"Saturn will be rising around 11.30pm directly beneath the Tainui
canoe and the bright star Betelgeuse. So I hope you have a good
evenings viewing and look forward to hearing how you all get on with
finding these great sights in our skies."

The South African Astronomical Observatory - What's Up - April
http://www.saao.ac.za/sky/apr.html
Saturn is easily seen in the northwestern sky, looking like a fairly
bright yellowish star 'below' Orion. The easiest way to find it is to
locate Orion's Belt, then the bright stars Rigel (above the Belt as
you face north) and Betelgeuse. Imagine a line from Rigel through the
Belt to Betelgeuse, then extend the line further to the northeast
until you get to a yellowish bright "star" about as far from
Betelgeuse as Betelgeuse is from Rigel. The rings this year are open
about as wide as they ever appear from Earth - but catch them this
month before Saturn gets too low in the sky for easy viewing.

30 Moon near Jupiter at 5h UT (evening sky).
The Planets: Four of the brightest planets remain visible in the
evening sky this month. Venus in Taurus continues its dazzling display
in the western sky. Jupiter remains brilliant at just one month past
opposition. A small telescope will show Jupiter's clouds and its 4
brightest moons. Saturn is located about mid-way between the stars
Castor and Betelgeuse. Its magnificent rings are another easy target
for small telescopes. Mars appears as a tiny orange-colored point of
light in the constellation Taurus. Finally, elusive Mercury moves into
the morning sky.

Betelgeuse
http://www.thenakedsky.com/
It's up, it's down: Betelgeuse is the Oprah Winfrey of the night sky.
Sometimes, it's just plain XXL but then, every few years, it really
pushes the small kids off the bus.
Betelgeuse is the only red star in Orion. Not only does this make it
easy to spot, its very color tells us that we're looking at a giant.
Unlike the thousands of blue/white stars we can pick out with the
naked eye, red stars have a very low surface brightness. So when look
at a red star we can only see it, not because it's bright, but because
its radiating surface area is just so vast.
Even "at rest" Betelgeuse is 200 million times bigger than our own
sun. Every so often, however, it has a cosmic case of indigestion and
swells to truly mind-boggling proportions. Placed at the center of our
solar system, Betelgeuse's swollen girth would encompass the orbit of
Jupiter, 465 million miles out. That would put Betelgeuse at 1000
million miles in diameter?edge to edge, a billion miles. Not just a
giant, but a supergiant.
The name "Betelgeuse", by the way, comes from the Sumerian for "armpit
of the sheep". Not kidding.
Another interesting fact: Betelgeuse is rumored to be the next star in
our own galaxy to explode as a Type II Supernova.
Rigel
Compare Betelgeuse with Rigel. To the human eye both are both equally
bright, yet they have very obviously different colors. Rigel is a mere
100 times as wide as our sun, some fifteen times smaller than
Betelgeuse. It's also twice as far away from us as the red giant. Yet
Rigel maintains its position as the 7th brightest star in our night
sky by burning at 9000 degrees Kelvin three times as hot as
Betelgeuse. Rigel is a blue giant; an intensely hot, young sun.

The 10 Brightest Stars - 10 Betelgeuse
http://www.space.com/scienceastronomy/brightest_stars_030715-10.html
Betelgeuse is an ancient star approaching the end of its life cycle.
Because of its mass it might fuse elements all the way to iron and
blow up as a supernova that would be as bright as the crescent Moon,
as seen from Earth. A dense neutron star would be left behind. The
other alternative is that it might evolve into a rare neon-oxygen
dwarf.

BRIGHT STARS AND THE STARS CLOSEST TO EARTH
http://www.enchantedlearning.com/subjects/astronomy/stars/bright.shtml
(pronounced "beetle juice") Betelgeuse (alpha Orionis) is the
second-brightest star in the constellation Orion and one of the
brightest stars in the sky. It is a supergiant star, reddish in color,
and over 600 million miles in diameter (almost 1,000 times bigger than
the Sun but cooler than the Sun). If Betelgeuse were at the center of
our Solar System, it would extend beyond the orbit of Jupiter. It is
520 light-years from Earth. It is a variable star, varying in
magnitude from 0.3 to 1.2 over a period of about 7 years, averaging
about 0.70. It is the only star (other than our sun) for which we have
surface images.
