APOD 3.3


After a awesome streak through the northern hemisphere, the brightest comet in decades is now in the south. This picture was taken in New Zealand and was recorded during evening twilight. The view features the bright coma, and a gorgeous sweeping tail of Comet McNaught. The 5 second long exposure came close to the real visible magnitude. This amazing spectacle is one not to be missed by any astronomers.

APOD 3.2


Wow, look at the picture. Do you see the coat hanger? I do! Shocking that some constellations actually have some resemblance to what they are names. But wait!! It's not a constellation, it's an Asterism!! This means it was named after something it looked like (makes more sense now eh?). The ultimate question is whether or not the coat hanger is a star cluster. An asterism cannot be a star cluster because of its definition. It is still debated whether or not it is one, but for posterity's sake, we'll say it is.

APOD 3.1

NGC 6960: The Witch's Broom Nebula

This light shown is a result from an exploding star in the Veil Nebula. The west end of the nebula is shown. This is not an explosion as you imagine it. It is merely an expanding ball of gas. The supernova remenant lies about 1200 light years away from earth in the constellation cygnus. It is more commonly known as the Whitch's broom.
