How do you feed a hungry quasar? With a ‘super boost,’ scientists say

This graphic shows the center of a newly formed star cluster (stars are in yellow), within which the seed black hole gets its super boost of gas (shown in blue). (Credit: Natarajan, Alexander, Yale)

Colliding galaxies left a stream of gas 2.6 million light years long

The bridge of gas (shown in green) stretches from the large galaxy at the bottom left to the group of galaxies at the top. A third nearby galaxy to the right also has a shorter stream of gas attached to it. (Credit: Rhys Taylor / Arecibo Galaxy Environment Survey / The Sloan Digital Sky Survey Collaboration.)

Physicists use lasers to collect weak signals

 Professor Howard Milchberg.  University physicists working in the Intense Laser Matter Interactions group have made two breakthroughs in recent months: One allows them to send high-powered lasers through atmosphere, and another uses this technology to collect weak signals from a distance.

Optical fibres from thin air

An “air waveguide” has been used to enhance light signals collected from distant sources. A single waveguide could be used to send out a laser and collect a signal. (Credit: Howard Milchberg)

Hubble traces the halo of a galaxy more accurately than ever before

This image shows the stunning elliptical galaxy Centaurus A. Recently, astronomers have used the NASA/ESA Hubble Space Telescope to probe the outskirts of this galaxy to learn more about its dim halo of stars. (Credit: ESA/Hubble)/NASA/Digitized Sky Survey/MPG/ESO

‘Transformer’ pulsar is more than meets the eye

These artist's renderings show one model of pulsar J1023 before (top) and after (bottom) its radio beacon (green) vanished. Normally, the pulsar's wind staves off the companion's gas stream. When the stream surges, an accretion disk forms and gamma-ray particle jets (magenta) obscure the radio beam. NASA's Goddard Space Flight Center

Massive neutrinos and new standard cosmological model: No concordance yet

 The research group demonstrates that adding such massive neutrinos to the standard model does not really explain all datasets. Credit: The Milky Way, NASA. Read more at: http://phys.org/news/2014-07-massive-neutrinos-standard-cosmological-concordance.html#jCp

Update: Einstein is still full of surprises

What is the view of time that Albert Einstein presents to us in special relativity? Einstein tells us that there is no separate ‘time’ or ‘space.’ ‘Time’ and ‘space’ cannot be separated; they are a united whole.
