ATV: a very special delivery

submitted by: cristina
Early in 2008, an Ariane 5 rocket blasted off from Europe’s spaceport in French Guiana. The rocked carried the most sophisticated lorry ever built – the European Space Agency’s Automated Transfer Vehicle, the ATV. From its first flight, ATV will play a vital role in International Space Station (ISS) servicing. Every 12 months or so, the ATV will haul 7.5 tonnes of cargo to the ISS, 400 km above the Earth. The video - addressed mostly to the youngsters- tells the story of a very...

Earth's Outlook from Above

Fifty years after Sputnik, satellites peering down on Earth have become valuable scientific tools to study the global environment and offer much needed insight into the future of our planet.

Resonance: Radio, Wineglasses, Opera Singers and Cycles

submitted by: RayTomes
Resonance is the quality of transmitting even tiny signals between systems that are tuned to the same frequency. Given that cycles of common period are found pervading many different disciplines, perhaps an explanation may be found in resonance. An example is the 160 minute (and associated 80 minute cycle) cycle, found in biological systems, outer planetary spacings, the rotation rates of planets, asteroids and binary stars, solar oscillation and flux and galactic cores. A cosmic pervading...

586 Million Year Cycle in Geology Matches Galactic Super-Cluster Spacings

submitted by: RayTomes
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,...

Galaxy-Quasar Associations: Is the Big Bang Bung?

submitted by: RayTomes
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...
