My first astro-photo! The brightest of all nebulae visible in the night sky and a real gem for southern hemisphere astronomers, The Keyhole Nebula NGC 3372 reflects the UV light of the surrounding stars creating the wonderful reddish-pink nebulosity as seen in this image. The large orange coloured star bottom centre of the photo is Eta Carina. A super massive star that is nearing the end of its life and estimated to be 100 times larger than the sun and 16 Billion kilometers across! Astronomers now believe that it's supernova explosion may be so large that it will collapse in on itself, dragging its companion star along for the ride. The resulting black hole and gamma ray brust could potentially be so great that it will wipe out any planet or star in its beam.

The chart shows the The Keyhole Nebulae in relation to the Southern Cross "Crux" as seen during the winter months.
To find the keyhole nebula, find Hadar (second pointer) then make a line to Acrux. Project that same distance across and about 1 finger width with up and you should notice a bright fuzzy area in the night sky. This is the Keyhole Nebula.
I have only listed Eta Carina in the star table. m is the apparent visual magnitude and spectral type as indicated. |
