Pulsars make a GPS for the cosmos

CSIRO scientists have written software that could guide spacecraft to Alpha Centauri, show that the planet Nibiru doesn't exist... and prove that the Earth goes around the Sun.

Spaceflight alters bacterial social networks

In two NASA-funded studies biofilms grown aboard the International Space Station bound space shuttle were compared with those grown on the ground. The study results show for the first time that spaceflight changes the behavior of bacterial communities.

Cosmic turbulences result in star and black hole formation

Just how stars and black holes in the Universe are able to form from rotating matter is one of the big questions of astrophysics. Now, a new publication by HZDR physicists in Physical Review Letters shows how magnetic fields can also cause turbulences within "dead zones," thus making an important contribution to our current understanding of just how compact objects form in the cosmos.

Dwarf galaxy caught ramming into a large spiral

Observations with NASA's Chandra X-ray Observatory have revealed a massive cloud of multimillion-degree gas in a galaxy about 60 million light years from Earth. The hot gas cloud is likely caused by a collision between a dwarf galaxy and a much larger galaxy called NGC 1232.

Cosmology in the lab using laser-cooled ions

Scientists used laser-cooled ions in so-called 'ion Coulomb crystals'. They were able to show for the first time how symmetry breaking can be generated in a controlled manner and how the occurrence of defects can then be observed.

Hubble finds source of Magellanic stream

Astronomers using NASA's Hubble Space Telescope have solved a 40-year mystery on the origin of the Magellanic Stream, a long ribbon of gas stretching nearly halfway around our Milky Way galaxy.

Quasar observed in 6 separate light reflections

Quasars are active black holes -- primarily from the early universe. Using a special method where you observe light that has been bent by gravity on its way through the universe, a group of physics students from the Niels Bohr Institute have observed a quasar whose light has been deflected and reflected in six separate images. This is the first time a quasar has been observed with so many light reflections.

First hundred thousand years of our Universe

A new analysis of cosmic microwave background radiation data by researchers with the Lawrence Berkeley National Laboratory has taken the furthest look back through time yet - 100 years to 300,000 years after the Big Bang - and provided tantalizing new hints of clues as to what might have happened.

The odd couple - two very different gas clouds in the galaxy next door

ESO's Very Large Telescope has captured an intriguing star-forming region in the Large Magellanic Cloud - one of the Milky Way's satellite galaxies. This sharp image reveals two distinctive glowing clouds of gas: Red-hued NGC 2014, and its blue neighbour NGC 2020. While they are very different, they were both sculpted by powerful stellar winds from extremely hot newborn stars that also radiate into the gas, causing it to glow brightly.
