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]

Quasars are Mileposts for Marking the Universe’s Expansion

  Scientists can’t travel deep space the way Columbus sailed and charted the New World or Lewis and Clark mapped the west. But, researchers at Case Western Reserve University and two partnering institutions have found a possible way to map the spread and structure of the Universe, guided by the light of quasars. This is [continue reading]

Dark Energy Exists!

  Dark energy, a mysterious substance thought to be speeding up the expansion of the Universe is really there, according to a team of astronomers at the University of Portsmouth and LMU University Munich. A visual impression of the data used in the study representing the relevant extra-galactic maps as shells of increasing distance from [continue reading]

Distant Starburst Galaxy Pinpointed... and it has Companions

  An international team of astronomers led by Fabian Walter of the Max Planck Institute for Astronomy has managed for the first time to determine the distance of the galaxy HDF850.1, well-known among astronomers as being one of the most productive star-forming galaxies in the observable universe. The galaxy is at a distance of 12.5 [continue reading]

Faintest Distant Galaxy Discovered

  Astronomers at Arizona State University have found an exceptionally distant galaxy, ranked among the top 10 most distant objects currently known in space. Light from the recently detected galaxy left the object about 800 million years after the beginning of the universe, when the universe was in its infancy. False color image of the [continue reading]

Quasars shine a new light on cosmic distances

  An international team of scientists has developed a method to determine the distances to quasars throughout the universe. This could allow quasars to be used as standard candles. The researchers found characteristic patterns in the light given off by a group of quasars and say that these regularities are directly related to the redshift [continue reading]
