Astronomy Picture of the Day - Pleiades over Half Dome
NASA ^ | 27 Jan, 2025 | Image Credit & Copyright: Dheera Venkatraman

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 astrophotographer was unexpectedly rewarded by an electrical blackout, making the background sky unusually dark.

The Pleiades cluster is not the closest one to earth, but it is the brightest and most recognizable.

It's typically dark in many of the national parks, so much so many have placard signs boasting about it as great night sky viewing.

There are no lights around Half Dome in Yosemite.

So the "blackout" probably didn't have much effect.

Love how APOD throws around all these time ranges with never an explanation as to how they were arrived at.

A beautiful picture! I used to dream of climbing the Half-Dome, NOT THE FACE, mind you, but hiking up the side. I won’t get there, but what a beautiful place, they should use that picture for promos!

I thought it was Half Dome (Dome=Kamala). Look up dome in the urban dictionary.

That could be Kamala or Hunter....

..”From the expression “to the dome;” the act of ingesting an entire quantity of a substance. Normally associated with druga and alcohol, it describes the act of consuming the whole of a given substance, such as a beer, a joint but not limited to any particular substance. ..”
