Here we have another globular cluster: M53. You don’t see this one imaged too often, but it’s still quite pretty. I’ve never met a globular cluster I didn’t like.
It’s one of the more distant globular clusters in our galaxy, about 60,000 light-years away.
In these short summer nights, I want to take advantage of every moment of darkness. Right now, the galaxy M100 is up in the hours before midnight, and the “Tulip Nebula” – formally SH2-101 – rises just as M100 sets. So for this past week, I’ve been imaging both objects. But no more clear skies…
The main galaxies in this image go by the unassuming names of NGC5033 and NGC5005 (5033 is the larger spiral galaxy.) They’re within a constellation named Canes Venatici, or “the hunting dogs.” Look closely, and you’ll spot a few other galaxies – some large but more distant, and some that are just really small and…
Formally this nebula is called vdB93, but more commonly it is a part of the “seagull nebula.” The larger nebula really does look like a flying bird, but it’s a little too big to fit in the field of view of my telescope – so I focused instead on its “head” where most of the…
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.
Globular clusters are mysterious objects – they are dense clusters of stars, some containing hundreds of thousands of them. And they’re not within the plane of the Milky Way galaxy; they are scattered around it. How they formed is a bit of a mystery. Did they form with our galaxy, or are they the cores…
Like the Bubble Nebula, and Thor’s Helmet, this is formed by the fast stellar wind of the extremely hot star at its heart – which interacts in complex ways from the wind left over from when this star was a red giant. This is roughly 5,000 light-years away. These images were taken over the span…
