Did the Big Bang exist?

© Afrim Constantin –

Published online the first results of the satellite ESA polarized dust emission at high galactic latitudes. Results, which put a heavy question mark on the detected signal to the South Pole from BICEP2, too contaminated to be the unmistakable signature of primordial gravitational waves. It was to be the signal oldest of the universe, the

Gravitational waves pulverized

© Afrim Constantin –

Contrary to what was announced last spring, there is still no firm evidence of the presence of “ways B” primordial – dating back to the Big Bang – the polarization of the CMB. This is the conclusion, after months spent side by side to analyze the data, the team of ESA’s Planck satellite and telescope

The migration of the planets from asteroids told

© Afrim Constantin –

New research on the objects orbiting in the main asteroid belt shows a wide variability in their composition and size, a sign of the great planetary upheavals during the first billion years of the Solar System. The study is published in Nature. The turbulent history of the chaotic evolution of the Solar System has left

The super Map of Dark Matter

© Afrim Constantin –

Exploiting the effect of the gravitational lens and the power of the instrumentation of the Space Telescope, a team of scientists has managed, a few years ago, to reconstruct the distribution of dark matter in the cluster of galaxies called Abell 1689 with unprecedented detail. A few years ago we had the news of the

A new particle for dark matter

© Afrim Constantin –

A group of researchers at the University of Southampton has proposed the existence of a fundamental particle to explain the nature of the enigmatic dark matter. It is a new experimental approach in space that attempts to shed light on an unknown sector where it is expected that these particles may exist. Researchers from the

Spiral galaxies

© Afrim Constantin –

In 2012, the Hubble Space Telescope took a look at a spiral galaxy in the Hydra constellation. The sharp angle clearly highlights the features, including the elongated nucleus and the bar that connects to the spiral arms. The Hubble Space Telescope for NASA and ESA has identified the spiral galaxy ESO 499-G37, catching it on

It was a star similar to the Sun but much more “dusty”, the first scientific objective LBTI interferometer installed at the Large Binocular Telescope, of which Italy with the INAF is a partner. Excellent results: the tool has allowed us to study with great accuracy the distribution of dust around the Astra. LBTI will be

The comet 67P Churyumov-Gerasimenko amazes us again

© Afrim Constantin –

A Scandinavian study guide, based on some observations of ionized gas around the comet 67P, allows for the first time to follow the development of cometary magnetosphere as the body approaches the Sun and interacts with the solar wind. Rosetta is probing the comet 67P Churyumov-Gerasimenko, robotically in every way possible, and we have already
