Time is T + 500,000,000 years. Stars - Go, Galaxies - Go. Keck, De-ionization is underway
Published July 10th, 2007 in Science, Time and Space. 5 CommentsIn what is to me the most scientifically important paper of the year, astronomers today announced the discovery of 2 galaxies at redshifts > 10 and 4 galaxies with redshifts >7.7. The most distant of these galaxies was forming stars just 500,000,000 years after the Big Bang, and contributed to the re-ionizing the universe after […]

If you play close attention to space exploration programs you may have noticed that we only fling things at Mars ever two or so years. In 2003, the year of the rovers, NASA launched Spirit and Opportunity and ESA launched Mars Express […]
All good things come from the Cosmic Microwave Background
Published July 3rd, 2007 in Science and Space. 2 CommentsAll good things come from the Cosmic Microwave Background. The geometry of universe is defined as flat from studies of the CMB using WMAP. The age of the universe is defined as 13.7 +/- 0.2 billion years from studies of the CMB using WMAP. Even the expansion rate of the universe is defined as 71 […]
