Explanation: Stars come in bunches. The most famous bunch of stars on the sky is the Pleiades, a bright cluster that can be easily seen with the unaided eye. The Pleiades lies only about 450 light years away, formed about 100 million years ago, and will likely last about another 250 million years. Our Sun was likely born in a star cluster, but now, being about 4.5 billion years old, its stellar birth companions have long since dispersed. The Pleiades star cluster is pictured over Half Dome, a famous rock structure in Yosemite National Park in California, USA. The featured image is a composite of 28 foreground exposures and 174 images of the stellar background, all taken from the same location and by the same camera on the same night in October 2019. After calculating the timing of a future juxtaposition of the Pleiades and Half Dome, the astrophotrographer was unexpectedly rewarded by an electrical blackout, making the background sky unusually dark.

This is the first time I have ever impressed by a Subaru.

Has anyone stood at that massive door on the left and said “Friend” in Elvish?

Always take a half dome for granite.

I’d give it a try but you have to travel through Morder on the Pacific to get there.

It look like the other half was sheared-off.

I tried it and they handed me a Honeydew. I think my accent is bad.

You have some nice pictures on your Profile Page.

Too bad they have “Photobucket” across them all.

I loved discovering the Pleiades as a 12 year old astronomy nerd, but seeing it rise earlier and earlier in the western sky during the fall made me depressed because I knew Winter was just around the corner. Even though the winter sky is brilliant it was still winter, and well, school was in session which I hated.

What I like about The Pleiades is it’s easy visibility. Naked eye, binoculars, or even small telescopes show it really well. If
I’m ever blessed to go to a dark enough site maybe see some nebulosity.
Another favorite is the Double Cluster, but that’s for another time🙂🔭

Shows how big the valley is where Half Dome is.
The glacier was bigger and stronger!!
