APOD: Pleiades over Half Dome (2022 Jul 19)

Image Pleiades over Half Dome

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.

WOW!!! :shock:

Are those Pleiades blue, or are they blue?

They are... blue. Even to me.

But there is not a lot of color in the rest of the picture, neither on the Earth nor in the sky.

With just a tiny bit of imagination, the Pleiades seem to be “mirrored” (sort of) in Half Dome’s monochromatic topology.
