Adam Riess of Johns Hopkins University is an astronomer designing experiments and devices to advance understanding of the geometry of the universe and the story of both its beginning and its end. MacArthur Fellowships offer the opportunity for Fellows to accelerate their current activities or take their work in new directions. The unusual level of independence afforded to Fellows underscores the spirit of freedom intrinsic to creative endeavors. The extraordinary creativity of ...

The longest geological cycle identified is described as about 600 million years in "Megacycles", the proceedings of a geological conference, Edited by G Williams. However Prof S Afanasiev of Moscow has determined the cycle very accurately to be 586.24 million years using his Nanocycles Method. It so happens that cosmologists, Broadhurst, T.J., Ellis, R.S., Koo, D.C. & Szalay (Nature 343, p 726) have observed regular mega-walls of galaxies at spacings that they describe as 128 Mpc/h, which...

When we see a galaxy and a quasar near each other in the sky, it might be because they are really near each other, or it might be that they are far apart and just along the same line of sight. Tests performed by Alan Stockton (Astrophysical Journal 223:747-757, "The Nature of QSO Redshifts", 1978) on a sample of such pairs have shown that some galaxy-quasar pairs have the same redshift and so are accepted as being at the same distance. Other pairs with very different redshifts however have...

Regularly spaced clouds appear in Jupiter's belts, sometimes white spots and sometimes swirling waves. A polar projection of Jupiter, made by NASA from the 2000 flyby, allows accurate testing of the hypothesis that these waves form as predicted by the Harmonics Theory. It is found that expected strong harmonics 12, 24 and 72 are present.

The NASA/ESA Hubble Space Telescope, in collaboration with several other ground- and space-based telescopes, has captured a galaxy being ripped apart by a galaxy cluster's gravitational field and harsh environment. The finding sheds light on the mysterious process by which gas-rich spiral-shaped galaxies might evolve into gas-poor irregular- or elliptical-shaped galaxies over billions of years.
