The environment around our planet

© Afrim Constantin –

700 satellites are stacked in a more or less orderly orbit the Earth. Few fall to the base, as expected, at the end of the mission. Most continue to wander over our heads, out of control. To date there is only a catalog of this complicated traffic pollution. It’s called JSpOC and is in the

Gaia -ESO, the public spectroscopic survey carried out in one of the four telescopes at ESO VLT, has successfully completed its first two years of observations, for a total of 135 nights on the 300 planned. More than 5,000 high-resolution stellar spectra have been made available since last November to the international scientific community. Source: NASA/ESO/INAF

Found the fuel of star formation?

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

© Afrim Constantin –

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.
