First Direct Evidence of Cosmic Inflation and the Big Bang

  Almost 14 billion years ago, the Universe we inhabit burst into existence in an extraordinary event that initiated the Big Bang. In the first fleeting fraction of a second, the Universe expanded exponentially, stretching far beyond the view of our best telescopes. All this, of course, was just theory.  Image Credit: NASA Researchers from [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]

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]

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]
