Preliminary results from ESA's Planck mission to study the early Universe indicate that the data quality is excellent. This bodes well for the full sky survey that has just begun. Planck started surveying the sky regularly from its vantage point at the second Lagrange point of the Sun-Earth system, L2, on 13 August. The instruments were fine-tuned for optimum performance in the period preceding this date. ESA's Planck microwave observatory is the first European mission designed to study the...

Two astronomers at the Space Telescope Science Institute (STScI) in Baltimore, Md., Dr. Marc Postman and Dr. Ken Sembach, have been selected among 19 science teams to conduct year-long studies of new concepts for NASA's next generation of major observatories. The studies will help the agency make decisions about how it explores the heavens in the future, following the Astronomy and Astrophysics Decadal Survey. Postman's group will study the feasibility of building the Advanced Technology...

NASA -- You don't get much closer to the big bang than this. Scientists peering back to the oldest light in the universe have evidence to support the concept of inflation, which poses that the universe expanded many trillion times its size faster than a snap of the fingers at the outset of the big bang. We're talking about when the universe was less than a trillionth of a trillionth of a second old. In that crucial split second, changes occurred that allowed for the creation of stars and...

Large Population of Galaxies Found in the Young Universe with ESO's VLT ESO -- It is one of the major goals of observational cosmology to trace the way galaxies formed and evolved and to compare it to predictions from theoretical models. It is therefore essential to know as precisely as possible how many galaxies were present in the Universe at different epochs. This is easier to say than to do. Indeed, if counting galaxies from deep astronomical images is relatively straightforward,...

  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
