Quasars Influence Galaxy Growth

  Quasars are among the brightest, oldest, most distant, and most powerful objects in the Universe. Powered by massive black holes at the center of most known galaxies, quasars can emit enormous amounts of energy, up to a thousand times the total output of the hundreds of billions of stars in our entire Milky Way.

The 3D Fireworks of an Exploded Star

  In 1901 the star GK Persei gave off a powerful explosion that has not stopped growing and astonishing ever since. Now a team of Spanish and Estonian astronomers has reconstructed the journey of the emitted gas in 3D which, contrary to predictions, has hardly slowed down its speed of up to 1,000 km/s after [continue reading]

Telescope Takes Temperature of the Universe

  Astronomers using a CSIRO radio telescope have taken the Universe’s temperature, and have found that it has cooled down just the way the Big Bang theory predicts.

How a Middleweight Black Hole is Created

  A new model co-developed by BMCC Science Professors Saavik Ford and Barry McKernan shows how an elusive type of black hole can be formed in the gas surrounding their supermassive counterparts. This simulated image shows the interaction between a massive gas giant planet (comparable in mass to Jupiter) and a surrounding protoplanetary disk of [continue reading]
