The Curiosity rover NASA has used the SAM tool to analyze xenon, a heavy noble gas that occurs naturally in nine isotopic forms, to better understand the story of the lost Martian atmosphere. While the rover Curiosity NASA carried out in recent weeks the detailed examination of the rock layers of the outcrop “Pahrump Hills”

Impacts of processes of star formation

© Afrim Constantin –

A study on the Cat’s Paw Nebula provides new clues on the physical mechanisms that influence the processes of star formation. The observations, made with the Smithsonian’s Submillimeter Array, allowed astronomers not only to measure, for the first time, the magnetic fields in spatial regions of different sizes but to find the root cause which

Ia Supernovae can help us understand dark energy?

© Afrim Constantin –

A study of one hundred galaxies has allowed a group of researchers to select a list of the best type Ia supernovae that can be used to better define the cosmic distances with an accuracy better than twice that previously obtained, and then to determine the rate of the accelerated expansion of the Universe. A

A heat map of Venus, obtained by the method of occultation, reserve two surprises: a layer mysteriously hotter than it should, and an unusually warm morning. The leader of the study is Arianna Piccialli at the French LATMOS laboratory. Credit: ESA Although Venus Express, the European probe that has scrutinized the “hot sister” of the

Non-gravitational dark matter

© Afrim Constantin –

A recent study of 72 clusters of interacting galaxies provides a test to examine the non-gravitational forces acting on dark matter. The results contradict at least one of the major theories and place limits on the nature of the particles, excluding those similar to the proton. The results are published in Science. Thanks to collaboration

A new method to determine the rotation period of Saturn was presented in an article in the latest issue of Nature. To put it in place, a group of researchers led by Ravit Helled, at Tel Aviv University made possible the measurements of Saturn’s rotation period. How long is a day on Saturn? A little

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
