This scenario was suggested by Konstantin Batygin, a researcher at Caltech that deals with planetary sciences, and Gregory Laughlin of the University of California in an article appearing in this week in Proceedings of the National Academy of Sciences (PNAS). A study prepared by researchers at Caltech and the University of California at Santa Cruz
The mysterious impact results in a 400 km crater
© Afrim Constantin –
It is about a crater of 400 kilometers that doesn’t exist anymore nowadays. A group of researchers, digging for more than two miles below the earth’s crust, found traces of this violent impact that can be traced back over 300 million years ago. In central Australia were found fragments of a huge meteorite that smashed
Nexus, a solution to quantum gravity?

According to a recent study conducted by Stuart Marongwe, the way to reconcile the physical phenomena of the macroscopic and the microscopic world would pass through a new theory of quantum gravity that not only make it possible to describe the black holes but also could shed light on dark matter and on dark energy,
Supernovae – factories of dust?
© Afrim Constantin –
A study published in Science, analyzing a remnant of supernova that was found in our galaxy, suggests that the dust provided by explosion can survive the successive shock wave. This submits the fact that the dust of first galaxies may have been mainly produced by supernovae. In older galaxies, or those already in the primordial
Rosetta found molecular nitrogen

The new findings, which are published in an article in the latest issue of the journal Science, are based on 138 measurements collected by the instrument ROSINA (Rosetta Orbiter Spectrometer core Ion and Neutral Analysis) on board Rosetta between 17 and 23 October, when the spacecraft orbited about 10 km from the center of the
P / 2012 F5: an asteroid explosive
© Afrim Constantin –
A team of astronomers from the Jagiellonian University in Krakow has carried out a detailed study of P / 2012 F5, the most promising of a new class of asteroids. A team led by astronomers at the Jagiellonian University in Krakow, Poland, has recently used the WM Keck Observatory in Hawaii to observe a peculiar

Habitable planets
© Afrim Constantin –
Researchers from the Australian National University and the Niels Bohr Institute in Copenhagen have calculated the percentage of stars in the Milky Way that could host planets in the habitable zone. The results show that billions of stars may have from one to three planets in the habitable zone Thanks to the data collected by
