Drilling means learning

The Curiosity rover has collected and started the analysis of her second sample of Martian rock that seems to have formed in a lake environment more acidic than the previous site. Because of the fragility of the rock, has been used a technique of drilling hammer with less energetic. Credit: NASA/JPL-Caltech/MSSS If the first bite
The eyes on the Lobster Nebula

The set of gas clouds visible in this image form huge stellar incubator named Lobster Nebula, known as Gum56 and it shows piles of just born hot stars. Obtained with the VLT Survey Telescope, this could be the sharpest picture ever produced of this object. The brilliant tangle of clouds of gas that can be
GMRT joins the team SKA

Giant Metrewave Radio Telescope (GMRT), located near Pune in India, is an array of radio telescopes at metre wavelengths. It is operated by the National Centre for Radio Astrophysics, a part of the Tata Institute of Fundamental Research, Mumbai. At the time it was built, it was the world’s largest interferometric array. The Giant MeterWave
Submarine behemoths: Volcanoes

A study at the Earth Institute at Columbia University explains how the phenomenon of submarine eruptions follows surprisingly regular cycles: from two weeks to tens of thousands of years, and almost exclusively between January and July of each year. Possible relationships with the global climate. There are more than 10 thousand, hidden under the water.
Gravitational waves: tightening the circle

It is more of a hope, is almost a promise. INAF two astronomers, who study the elusive radiation predicted by the theory of general relativity of Einstein, explain why they are confident that it will be soon revealed the signal. Thanks to Planck and interferometers new generation, on Earth and in space “The take.” Luigi

Did the Big Bang exist?

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

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

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
