Astronomers identify a galaxy made of dark matter

[Barbllm]

"A team of astronomers led by David Li has recently confirmed the discovery of ten potential "dark galaxies," where starlight is so faint that it's extremely difficult to detect anything with traditional observatories. The new list also includes Candidate Dark Galaxy-2 (CDG-2), a celestial structure that might be composed of 99% dark matter and just 1% of normal matter."

 

(Dark Galaxy would be a good name for a band.  )

 

It was discovered with the Hubble telescope and the Euclid space observatory.

 

Dark matter (and dark energy) can be inferred because our observations of galactic mass don't match what Einstein's relativity equations tell us it should be.
