🧊 Lensing isn’t just mass.

🌌 χ drift ↑
⭐ mid-epoch smoothness
🔭 ring symmetry = stage contrast

Max signal when |χs − χl| ↑
If χs ≈ χl → drift fades.

The shape of this galaxy admittedly appears to be somewhat bizarre, so confusion would be forgiven. This is due to a cosmic phenomenon called #Gravitational #Lensing.

This could be the smallest clump of dark matter ever found October 14, 2025 ### Imma Perfetto Cosmos science journalist By Imma Perfetto The black ring and central dot show infrared image of a distant galaxy distorted by a gravitation lens. Orange/red shows radio waves from the same object. The inset shows a pinch caused by another, much smaller, dark gravitational lens (white blob). Credit: Devon Powell, Max Planck Institute for Astrophysics Astronomers may have detected a clump of dark matter 100 times smaller than any found so far. Alternatively, they suggest it could also be an ultracompact, inactive dwarf galaxy. The mysterious object, which has a mass of about 1 million times that of the Sun, was detected by the way its gravity distorts light passing through or near it in a phenomenon called ‘gravitational lensing’. This caused a small pinch to occur in the gravitational lensing caused by a much larger, distant galaxy. “It’s an impressive achievement to detect such a low mass object at such a large distance from us,” says Chris Fassnacht, professor in the department of physics and astronomy at the University of California Davis in the US.

According to this model, ordinary matter only makes up about 5% of the Universe. Dark matter, which doesn’t absorb, emit or reflect light, but does have gravity, should make up about 27% of the Universe to explain the way gravity clumps together galaxies and galaxy clusters. “Given the sensitivity of our data, we were expecting to find at least one dark object, so our discovery is consistent with the so-called ‘cold dark matter theory’ on which much of our understanding of how galaxies form is based,” says Devon Powell from the Max Planck Institute for Astrophysics (MPA), Germany. “Having found one, the question now is whether we can find more and whether the numbers will still agree with the models.” The research is described in 2 papers published in _Nature Astronomy_ and _Monthly Notices of the Royal Astronomical Society_ _._ Originally published by Cosmos as This could be the smallest clump of dark matter ever found * *

Einstein Ring Did you know about 'Einstein Ring'?

HerS 020941.1+001557 is the designation for a very distant galaxy that appears as a dramatic #Einstein #Ring due to a phenomenon called #Gravitational #Lensing.

Its light, emitted 11 billion years ago, has been bent and magnified by the gravitational field.
