Most Distant Galaxy is Forming Stars Extremely Fast

  University of Texas at Austin astronomer Steven Finkelstein has led a team that has discovered and measured the distance to the most distant galaxy ever found. The galaxy is seen as it was at a time just 700 million years after the Big Bang. An artist’s rendition of the newly discovered most distant galaxy [continue reading]

The Universe Might Not Be Expanding After All

  Cosmologist Christof Wetterich of the University of Heidelberg has uploaded a paper to the arXiv server in which he claims it’s possible that the theory of the expansion of the Universe might be incorrect. He suggests instead that the redshift observed by researchers here on Earth might be caused by an increase in the [continue reading]

The Universe Accurately Measured

  New results pin down the distance to the galaxy next door   After nearly a decade of careful observations an international team of astronomers has measured the distance to our neighbouring galaxy, the Large Magellanic Cloud, more accurately than ever before. This new measurement also improves our knowledge of the rate of expansion of [continue reading]

Most Peculiar Supernovae Explained by Failed Explosions

  Supercomputer simulations have revealed that a type of oddly dim, exploding star is probably a class of duds—one that could nonetheless throw new light on the mysterious nature of dark energy. A collaboration led by George Jordan at the University of Chicago’s Flash Center for Computational Science has conclusively demonstrated a connection between white [continue reading]

Quasars Unveil New Era in the Expansion History of the Universe

  BOSS, the Baryon Oscillation Spectroscopic Survey, is mapping a huge volume of space to measure the role of dark energy in the evolution of the Universe. BOSS is the largest program of the third Sloan Digital Sky Survey (SDSS-III) and has just announced the first major result of a new mapping technique, based on [continue reading]

Most Distant Galaxy from the Very Early Universe Spotted

  Discovery of small, faint galaxy opens window into deepest, most remote epochs of cosmic history   With the combined power of NASA’s Spitzer and Hubble space telescopes as well as a cosmic magnification effect, a team of astronomers led by Wei Zheng of The Johns Hopkins University has spotted what could be the most distant galaxy [continue reading]
