Thor’s Helmet

Taken just prior to Halloween in 2018, the southeastern knot of the Eastern Veil Nebula takes on a ghostly appearance when imaged in the Hubble palette with narrowband filters.

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.

Highlighted here is a recently discovered supernova in the galaxy M61, over 50 million light-years away! This exploding star outshines the entire core of its own galaxy, and many of the much closer stars seen within our Milky Way. The sheer power of this stellar explosion is unfathomable. It’s 50 million light-years away, which means…

This edge-on spiral is around 40 million light-years away within the constellation Coma Berenices. Lots of satellite and background galaxies to explore around it! Zoom in, and travel back in time – hundreds of millions of years.

This is the Tulip Nebula in Cygnus, but see that shell-like structure just above it, to the right a little? That’s the bow shock wave of Cygnus X-1, a stellar-mass black hole! It’s one of the most powerful X-ray sources in the sky – but don’t worry, our atmosphere protects you from it. 20 hours…

Another revisit of an old target, with better gear and better conditions. This is the Pelican Nebula in the constellation Cygnus. Shot in narrowband over one night, and presented in the “Hubble palette”. Two takes – one wider field, and one close-up with the stars removed. In both cases the image is rotated and mirrored…
