This pair of galaxies gets its name from their shapes. Both are viewed edge-on, and from this perspective we can see how a past interaction between the two warped them both. About 6 hours of exposure time from the backyard observatory.
Part of our Local Group of galaxies, the Triangulum Galaxy (M33) is about 3 million light years away and the most distant object visible to the naked eye under dark skies.
These past couple of nights, I revisited the Wizard Nebula – home of a star cluster about 7,000 light-years away within the constellation Cepheus. This is a false-color image in the “Hubble Palette” where red, green, and blue represent ionized Sulphur, Hydrogen, and Oxygen emissions respectively. Can you see the “wizard”? Hint: he’s lying on…
Technically this nebula is called IC63, but its common name “The Ghost of Cassiopeia” seems much more timely, given Halloween is just around the corner! Imaged all night last night, mostly in true colors with some Hydrogen emissions added in to enhance it.
Somewhere between 30 and 50 million light-years away, within the constellation Coma Berenices, lies NGC4565 – commonly known as the “Needle Galaxy”. It’s a spiral galaxy, but viewed edge-on – so we see its central bulge and the edge of the galaxy’s disc extending from it. Clouds of dust within the galaxy obscure the middle…
This is M27, the “Dumbbell Nebula,” about 1600 light-years away. It’s what’s called a planetary nebula – not because it has anything to do with planets, but because early observers confused them for planets. In reality it’s far more interesting. This is what’s left over when a medium-sized star runs out of Hydrogen to fuse,…
You’re looking at about 500,000 stars, balled up just outside of our galaxy. They are ancient; about 8 billion years old.
