"Nothing quite like the chaotic beauty of colliding
Observations last year with the Very Large Array, a network of radio telescopes in Socorro, N.M., indicated that a region near the center of one of the colliding
galaxies was producing stars at a furious rate.
Rahae helped prepare a report for Congress on the probability of objects from space colliding
In one scenario, if energetic quarks collide at a fireball's edge, the quark heading away from the collision's center might get away while its partner bogs down in the soup of still agitated, colliding
particles--the quark-gluon plasma.
Those results have made the idea of colliding
black holes seem less realistic.
Astronomers have discovered a pair of colliding
galaxies connected by a bridge of high-speed electrons and elongated magnetic fields.
This glow probably arises from electrons colliding
with sulfur dioxide gas spewed by the volcanoes.
In contrast, electrons colliding
with protons at much higher energies reveal that, in this range, gluons act much more like particles than strings (SN: 9/6/97, p.
Astronomers have for the first time caught supernova remnants in the act of colliding
. Although observers had seen evidence of past interactions between these shells of gas and dust blown off by exploded stars, the new images offer a rare glimpse of them "actually pounding into each other," says William P.
Because they are most often produced in that initial contact between colliding
nuclei, J/y particles end up moving through the remainder of the merged nuclear matter, or blob.
