New Radio Telescope Predicted to Find 700,000 New Galaxies!

  Australia’s newest radio telescope is predicted to find an unprecedented 700,000 new galaxies, say scientists planning for CSIRO’s (1) next-generation Australian Square Kilometre Array Pathfinder (ASKAP). The simulated galaxies ASKAP surveys WALLABY and DINGO.  WALLABY will survey a large portion of the sky and is predicted to find 600,000 new galaxies. DINGO will survey a smaller section [continue reading]

Telescope Network Zooms in on the Heart of a Distant Quasar

  An international team led by scientists from the Max-Planck-Institute for Radio Astronomy has succeeded in observing the heart of a distant quasar with unprecedented sharpness, or angular resolution. The observations, made by connecting radio telescopes on different continents, are a crucial step towards a dramatic scientific goal: to depict the supermassive black hole at [continue reading]

The Sharpest-Ever View of Black Hole Jets

  An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy. Left: The giant elliptical galaxy NGC 5128 is the radio source known as Centaurus A. Vast radio-emitting lobes (shown as orange [continue reading]

SETI Finds No Signs of Extraterrestrial Intelligence... Yet

  Astronomers have completed the first search for extraterrestrial intelligence on nearby exoplanets using very long baseline interferometry. A telescope’s angular resolution is its ability to distinguish small details of a distant object. The Hubble Space telescope, for example, has an angular resolution of about 100 milliarcseconds. That’s good but by no means the best. [continue reading]
