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]

Green Pea Galaxies May Give Insight in the Early Universe

  The rare Green Pea galaxies discovered by the general public in 2007 could help confirm astronomers’ understanding of reionization, a pivotal stage in the evolution of the early Universe, say University of Michigan researchers. A montage of the six Green Pea galaxies that University of Michigan astronomy researchers studied. Image Credit: Anne Jaskot Reionization [continue reading]

‘Sideline Quasars’ Helped to Stifle Early Galaxy Formation

  University of Colorado Boulder astronomers targeting one of the brightest quasars glowing in the Universe some 11 billion years ago say “sideline quasars” likely teamed up with it to heat abundant helium gas billions of years ago, preventing small galaxy formation. This is an artist’s impression of a distant quasar. The dust is hiding the view [continue reading]

Astronomers Discover Galaxies Near Cosmic Dawn

  A team of astronomers led by the California Institute of Technology (Caltech) has used NASA’s Hubble Space Telescope to discover seven of the most primitive and distant galaxies ever seen. This timeline shows the evolution of the Universe since the Big Bang. The new observations, labeled “Hubble 2012,” explored the deepest reaches of the [continue reading]

Most Distant Galaxy Yet Known Discovered

  By combining the power of NASA’s Hubble Space Telescope, Spitzer Space Telescope, and one of nature’s own natural “zoom lenses” in space, astronomers have set a new distance record for finding the farthest galaxy yet seen in the Universe. In this image, astronomers use NASA’s Hubble Space Telescope and a cosmic zoom lens to [continue reading]

Explosion of Galaxy Formation Lit Up Early Universe

  New data from the South Pole Telescope indicates that the birth of the first massive galaxies that lit up the early Universe was an explosive event, happening faster and ending sooner than suspected. The South Pole Telescope recorded temperature fluctuations in the cosmic microwave background, the light left over from the Big Bang, to [continue reading]
