This particular gamma-ray burst’s redshift of 8.2 corresponds to such a large distance that it indicates the presence of stars a mere 630 million years after the Big Bang—when the universe was just 5 percent of its current...
...three principal artists of Splashdown clearly have varied musical tastes, experimenting with everything from acid jazz to ambient trip-hop and hard-core guitar riffs. On their Redshift EP, sometimes these diverse elements come together in an interesting mesh, but often the combinations are jarringly incoherent. "Waterbead" incorporates ethereal vocals, jungle beats and one heavy metal interlude in a disconcerting jumble that misses the mark. The jungle beats sound particularly strange, as they sit on top of the melody, instead of forming the undercurrent of the song. In contrast, "The Archer" is a smoother ambient track, reminiscent of Luscious Jackson...
What impressed the research team was not just the fact that the gas was moving but how fast it was moving--6.5 million m.p.h., judging by the redshift. This is exactly the kind of searing speed a black hole ought to produce. While the Goddard scientists may not have the distinction of being the first to see a black hole itself, they are thus the first direct witnesses of its extraordinary power...
Molecular Line Emission at High Redshift--by Robert Brown, National Radio Astronomy Observatory. Phillips Auditorium, 60 Garden St. Tea at 3:30 p.m.; lecture...
Gunn, a Caltech astronomer, made no direct observations. In collaboration with three associates, he spent six years studying a wide variety of evidence-including Sandage's redshift measurements. For one thing, he examined the galaxies' brightness and movement, which offer clues to their mass. He also estimated the probable incidence of "black holes," small but extremely massive bodies that are invisible to astronomers. From these and other clues, Gunn's group concluded that the universe has no more than a tenth of the mass-and probably less -needed to close it. "Pulling all the arguments together," says...
