Found the fuel of star formation?

© Afrim Constantin –

A new study reports the observation of a river never seen before of cold hydrogen flowing into the space between the galaxies. This tenuous strand of gas detected in the vicinity of the nearby galaxy NGC 6946, may help to explain how some spiral galaxies are able to keep their constant rate of star formation.

Triggered black hole in M83

A microquasar hyperactive challenges every model of emission. Baptized MQ1, could send in the attic theories that postulate the existence of the black holes of intermediate mass. First author of the study, that was published today in Science Express, is Piedmont Roberto Soria. Artistic representation of a microquasar as MQ1, the black hole discovered in

Some Australian astronomers are going to publish in the journal The Astrophysical Journal, the more detailed study of the relationship between the speed of rotation of spiral galaxies and their shape, which varies from nearly flat discs to real balls.

The universe was born from a thawing

A German theoretical physicist has proposed a non-standard model of the creation of the universe: its origin has not been an extremely hot and dense phase, but a phase of slow and cold processing . The model also denies that the universe is expanding. In this map of the cosmic background radiation, the white bars

No stars? Blame the black holes

© Afrim Constantin –

Contrary to what was believed until now, astronomers have discovered that despite the complete absence of star formation some giant elliptical galaxies contain large amounts of cold gas. The lack of production of new stars in them would then be attributed to the activity of the jets of their central black holes. The elliptical galaxy

Using the microgravity environment aboard the International Space Station, scientists have designed a process of microencapsulation of concentrated anti-cancer drugs . With specific delivery systems could ensure a slow and localized release. A type of therapy that could potentially revolutionize the treatment of cancer.

If the space damages the immune system

© Afrim Constantin –

A group of researchers at the University of California Davis has studied the effects of microgravity space on the immune system of insects Drosophila, showing that the conditions in space can be harmful to the immune response. The results of the study can be found in PLOS ONE. An insect Drosophila infected with a fungus.

Galaxies merged supermassive black holes

Experts have obtained with the Subaru telescope, high-resolution images that allow us to study the emission originating from supermassive black holes ( SMBH ) in the central regions of gas-rich and bright galaxies. Examples of K-band images of bright and gas-rich galaxies colliding. The image size is 10 arc seconds. The individual shots clearly show

Brighter and Faster

A research group at UC Berkeley has made new studies of the supernova SN 2014J, photographed for the first time last month by Hubble. Finding that not only the celestial object is brighter than expected, but it also exploded at a rate much higher than average. These Swift UVOT images show M82 before (left) and
