‘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]

An Almost Perfect Universe Revealed by Planck

  Acquired by ESA’s Planck space telescope, the most detailed map ever created of the cosmic microwave background – the relic radiation from the Big Bang – was released today revealing the existence of features that challenge the foundations of our current understanding of the Universe. The anisotropies of the cosmic microwave background (CMB) as [continue reading]

The Age of Oldest Known Star Determined

  A team of astronomers using NASA’s Hubble Space Telescope has taken an important step closer to finding the birth certificate of a star that’s been around for a very long time. This is an illustration of the oldest star ever found in our solar neighborhood. The aging star, cataloged as HD 140283, lies 190.1 [continue reading]

Possible Birth Of A Quasar Witnessed

  Sighting may help improve understanding of the early Universe   Scientists in Australia believe they’ve identified a quasar in the process of lighting up, for the very first time. This discovery could help scientists answer lingering questions about how these exceptionally bright celestial bodies form, and how they helped the ancient Universe shape today’s galaxies. [continue reading]

New Revolutionary Theory of Dark Matter

  The Universe abounds with dark matter. Nobody knows what it consists of. Physicists from the University of Oslo have now launched a very hard mathematical explanation that could solve the mystery once and for all. SIGNS OF DARK MATTER: The image shows all the gamma rays recorded by the Fermi-LAT space probe as a map [continue reading]
