Clusters Exhibiting Strong Evidence of Dark Matter
| Galaxy cluster | Notes |
|---|---|
| Bullet Cluster | This collision between two galaxy clusters seems to have left a dark matter cluster in the space between them. |
| Abell 520 | This is actually a collision between two galaxy clusters. The galaxies and the dark matter seems to have separated out into separate dark and light cores. |
| Abell 2142 | A collision between two massive, X-ray luminous galaxy clusters. |
| Cl 0024+17 (ClG 0024+16, ZwCl 0024+1652) |
This is a recently coalesced merger of galaxy clusters, which has resulted in a ring of dark matter around the galaxies, yet to be redistributed. |

Famous quotes containing the words clusters, exhibiting, strong, evidence, dark and/or matter:
“What wondrous life in this I lead!
Ripe apples drop about my head;
The luscious clusters of the vine
Upon my mouth do crush their wine;
The nectarine and curious peach
Into my hands themselves do reach;
Stumbling on melons, as I pass,
Ensnared with flowers, I fall on grass.”
—Andrew Marvell (1621–1678)
“To a first approximation, the intentional strategy consists of treating the object whose behavior you want to predict as a rational agent with beliefs and desires and other mental states exhibiting what Brentano and others call intentionality.”
—Daniel Clement Dennett (b. 1942)
“One of the most important findings to come out of our research is that being where you want to be is good for you. We found a very strong correlation between preferring the role you are in and well-being. The homemaker who is at home because she likes that “job,” because it meets her own desires and needs, tends to feel good about her life. The woman at work who wants to be there also rates high in well-being.”
—Grace Baruch (20th century)
“Generally there is no consistent evidence of significant differences in school achievement between children of working and nonworking mothers, but differences that do appear are often related to maternal satisfaction with her chosen role, and the quality of substitute care.”
—Ruth E. Zambrana, U.S. researcher, M. Hurst, and R.L. Hite. “The Working Mother in Contemporary Perspectives: A Review of Literature,” Pediatrics (December 1979)
“and as you read
the sea is turning its dark pages,
turning
its dark pages.”
—Denise Levertov (b. 1923)
“As to the rout that is made about people who are ruined by extravagance, it is no matter to the nation that some individuals suffer. When so much general productive exertion is the consequence of luxury, the nation does not care though there are debtors in gaol; nay, they would not care though their creditors were there too.”
—Samuel Johnson (1709–1784)
