Cone Nebula

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…

A progression of photos taken at 15-minute intervals from 10:30 PM to 12:15 AM on the evening of Jan 20-21, 2019. Click to zoom in – there’s a lot of detail!

This is IC443, commonly known as the “Jellyfish Nebula” for obvious reasons! IC443 is a supernova remnant about 5,000 light-years away. This is a false-color, narrowband image consisting of a total of 20 hours of exposure time.

The three galaxies in the constellation Leo (M65, M66, and NGC3628) are about 31 million light-years away. Each one is being seen from a different angle; the one viewed edge-on is also known as the “Hamburger Galaxy”. Each has been interacting with each other, and distorting the shapes of these galaxies through the complex dance…

Located about 1,300 light-years away, the Iris Nebula is a reflection nebula – unlike most of the nebulas on this site, it’s not made of ionized gases emitting light of their own. It’s just starlight reflecting off clouds of dust. Reflection nebula are harder to image in light-polluted skies, since the narrowband filters we use…

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.
