M104 is known as the “Sombrero Galaxy” due to its visual appearance – but a deep, long-exposure image reveals its true structure. It’s a lenticular galaxy about 30 million light-years away, about 30% the size of our own Milky Way galaxy.
This galaxy is truly one of a kind, at least among that galaxies we have found. It’s a “polar ring galaxy,” probably the result of an unusual collision that left the core lenticular galaxy surrounded by the disk of another galaxy that it merged with. It’s a small, dim object, and just barely detectable from…
Hope to revisit this under better conditions in the future; but this came out OK considering a bright moon was out the night it was taken. The Pinwheel Galaxy (M101) is near the end of the handle of the Big Dipper in the sky, although physically it is tens of millions of light-years more distant.
We’re back with our live viewing of the cosmos! Join us as we view the Veil Nebula via a camera attached to our telescope – it’s a supernova remnant from a massive star that exploded 8,000 years ago, and it’s gorgeous. We’ll also talk about tonight’s expected meteor storm as the Earth passes through a…
Also in Hercules, M92 is often passed over for its larger and more dazzling neighbor, M13. But M92 is pretty in its own way! It’s also one of the oldest globular clusters in our galaxy (over 11 billion years old) and has some very interesting background galaxies around it too.
Somehow I’ve neglected to go back to one of the showcase galaxies of the spring sky with newer equipment and software: M101, the “Pinwheel Galaxy.” Located about 21 million light-years away within Ursa Major, this relatively close galaxy shows lots of active star-forming regions revealed by red HII gas. Those red spots are nebulae in…
This is IC342, located about 10 million light-years away. If it were anywhere else in the sky, it would be visible to the naked eye – but it lies behind the disk of our Milky Way galaxy, obscuring the view. This image is the result of 22 hours of total exposure time to try and…
