Astronomy Picture of the Day - Rubin's COSMOS field

Explanation: There are more than half a million galaxies in the central panel of this image from the NSF-DOE Vera C. Rubin Observatory in Chile. This is the COSMOS field, a patch of sky several times larger than the full moon, first observed by Hubble. It has also been observed by Webb and other telescopes because it contains comparatively few bright stars from our own galaxy, offering a relatively unimpeded view of other galaxies outside the Milky Way. The outer panels, numbered 1-10, show zoomed-in views of the corresponding small regions highlighted in the central panel. The variety of galaxy shapes and sizes is astonishing. Some of them are so far away that their light has traveled for billions of years before reaching Earth. Rubin will come back every couple of days to the COSMOS field as part of its ten-year Legacy Survey of Space and Time. It will allow a dynamic view of the COSMOS field and how the sky changes over time.

Will Rubin’s cosmos field be followed by the sandwich?

The ultimate goal of this project is to make a movie of the motions of all the objects that make up the cosmos. It will take a decade or more of continuous nightly observations to accomplish this......................

Half a million galaxies. Trillions of stars. Perhaps trillions of planets. But not a single planet with chocolate, Wi-fi, or a good five cent cigar.

I’m in awe. That’s just one small section of sky, a few lunar diameters wide. It’s a little mind- numbing….

That's my field. I thought it would be larger.

Nostalgic.

I had that LP, of course.

Saw the Mothers of Invention in person. Highly professional and well rehearsed.

I saw the MOI a couple of times. Pretty good.
