Analysis of galaxies shows local supercluster to be 100 times larger than previously thought. The supercluster of galaxies that includes the Milky Way has been found to be 100 times bigger in volume and mass than previously thought. The enormous region near the Milky Way has been mapped with newer precion and found that …
HZDR’s Michael Anders at the LUNA accelerator in Gran Sasso, Italy. (Courtesy: HZDR/M Anders). The only three elements created in the early universe, long before stars and galaxies began to form, were hydrogen, helium and lithium. According to Big Bang nucleosynthesis (BBN) theory, protons and neutrons combined to form these three elements just a …

The most significant news of late is the BICEP2 results – if you are unfamiliar with the result, let me first summarize the results and then offer feedback and alternative viewpoints. BICEP2 was the second generation BICEP (Background Imaging of Cosmic Extragalactic Polarization) instrument for astronomy located at Earth’s south pole. Possessing a greatly improved …
Christof Wetterich, a theoretical physicist at the University of Heidelberg in Germany, posted a paper on the arXiv preprint server, that offers a different cosmology in which the Universe is not expanding but the mass of everything has been increasing over time. Although the paper has yet to be peer-reviewed, none of the experts contacted …

In November 2012, a new distance record breaker has been weighed in with a photometric redshift of z ~ 10.8 which is roughtly 420 million years after the big bang. This is pretty significant. The Cluster Lensing and Supernova survey with Hubble (CLASH), and the Spitzer/IRAC has measured the photometric redshift and with the help …
This is a Digitized Sky Survey image of the oldest star with a well-determined age in our galaxy. The aging star, cataloged as HD 140283, lies 190.1 light-years away. The Anglo-Australian Observatory (AAO) UK Schmidt telescope photographed the star in blue light. Credit: Digitized Sky Survey (DSS), STScI/AURA, Palomar/Caltech, and UKSTU/AAO A team of astronomers using NASA’s …
Monday, 26 September 2011 by Estelle Asmodelle Cosmos Online This image shows the two hemispheres of a spherical mapping of the cosmic microwave background. New research examining the velocities of Type Ia supernovae suggests faster expansion in the northern hemisphere of the universe, challenging the cosmological principle that the universe is expanding uniformly in all …
Monday, 18 July 2011 by Estelle Asmodelle Cosmos Online An image of a barred-spiral galaxy (NGC1300) where you can clearly see the bar structure in the thin disk of the galaxy (the line through the middle of the galaxy which the spiral arms start from). The Milky Way is thought to have a bar like …
NEW METHOD OF MAPPING THE UNIVERSE USING QUASARS -BOSS. The biggest 3-D map of the distant universe ever made, using light from 14,000 quasars – supermassive black holes at the centers of galaxies billions of light years away – has been constructed by scientists with the third Sloan Digital Sky Survey (SDSS-III). See the Phyorg …
Planck’s version of the CIB is quite startling as well – as I am sure many of you have seen some of the photos by now, for there is more information as Planck looks through voids in the milky way to see deeper… Every spot in these images of the sky represents a point of …
