Traces of ice on 67P

From the pictures of the Rosetta’s OSIRIS camera, evolves the hypothesis that the region Hapi, located on the neck of the comet, may have traces of ice. Traces of ice are to be found on Hapi, a flat area situated on the neck of the comet 67P / Churyumov-Gerasimenko. And as suggested by the latest

Water on Jovian Moon seen by Hubble

© Afrim Constantin –

Scientists are estimating that the ocean is 100 km wide and it is located underneath 150 kilometers of crust, especially ice. In fact, this result appears to confirm a hypothesis which already existed since 1970, then repeated thanks to NASA’s Galileo spacecraft which measured the magnetic field of Ganymede in 2002. The largest of the

The disappearance of water on Mars

© Afrim Constantin –

NASA researchers have created a series of unique maps of the distribution of atmospheric water on Mars from which emerge new clues on what was to be the primitive ocean of the red planet. The results suggest that about 4.5 billion years ago, Mars had enough water to cover at least 20% of its surface

Exoplanets: where to look for signs of life

© Afrim Constantin –

If there is life out there, and it’s easy to think there is, if we can catch a glimpse (blurry and shy) of a star’s light, in the atmosphere of a distant planet, maybe we can catch also a sign of life. But bio-signatures are really the key of alien life? “Signs of life in

The shining of the Universe

© Afrim Constantin –

In the Milky Way the stars are born less than expected, considering the interstellar gas available. Researchers at MIT and Michigan State University have constructed a theoretical model that describes how galaxy clusters may regulate star formation. In their article, published last week in the journal Nature, describe this innovative model. Do the galaxies not

The insubordinate cluster of Milky Way

© Afrim Constantin –

The observations made with the Gemini Multi-Object Spectrograph (imaging mode) confirmed that the globular cluster is one of the less visible clusters ever found in our galaxy. A group of astronomers led by Dongwon Kim, Australian National University (ANU), found a small and distant cluster of stars that seems strangely out of place. Kim 2

Galactic ancestors

© Afrim Constantin –

Australian astronomers believe they have solved one of the mysteries of galactic evolution that concerns the fate of massive and compact galaxies that were present in the early Universe. A careful analysis of the galactic components has identified the missing population associated to spheroidal compact systems eliminating some issues that arose from the models of

Iron: founding life

© Afrim Constantin –

Shock waves similar to those due to the impacts of celestial bodies at the dawn of the Solar System were replicated by the “Z machine” in Albuquerque, New Mexico. The results show that, at the time of the formation of our planet, the vaporized iron was more abundant than previously thought in our days. There
