Chondrules – the origin of planets?

© Afrim Constantin –

Collisions between planetary embryos, the “seeds” of the primordial planets of the solar system, would be the process that gave birth to the mysterious chondrules – drops of molten rock before they solidified – present in meteorites. The research is published in Nature. If confirmed, it is one of those discoveries that will force to

How quasars influence the evolution of galaxies

© Afrim Constantin –

Astronomers have explored the most remote regions of space to study how quasars, among the brightest sources of the Universe, influence the evolution of galaxies. The numerical simulations relating to the dynamics of the gas which is ejected at high speed from the central regions of the quasar are consistent with observations obtained, in particular,

The focus is on Pluto

Two or more planets yet unknown beyond the orbit of Pluto could be responsible for that shaped in a particular way the trajectories of some remote celestial objects, known as ETNO (Extreme Trans-Neptunian Objects). These are the results of a study just published in the Monthly Notices of the Royal Astronomical Society journal. The caution

Spiral arms of Milky Way

© Afrim Constantin –

According to a study conducted by a group of Chinese astronomers, one of the spiral arms of the Milky Way, known as Shield-Centaur arm, could extend much further than assumed, wrapping all the way around our galaxy. It would hold a rare event ever observed in other spiral galaxies nearby. Since our solar system resides

The tools and MIDAS COSIMA aboard the ESA spacecraft have captured the first grains of dust from the comet Churyumov-Gerasimenko and have analyzed the shape and composition. Meanwhile it reduces the distance between the probe and the comet: engineers hope to get to 4 km in February. Credit: ESA/Rosetta/NAVCAM At a speed of 20.9 km

The results of the team led by Monaco and Murante, in publication of Monthly Notices of the Royal Astronomical Society, are at the forefront in Italy and put the group in a very small elite international Trieste. How do you rebuild on the computer the evolution of spiral galaxies? It was the question asked by

Everything through a 2.5 meters telescope

© Afrim Constantin –

Everything presented through a 2.5 meters telescope to the public and put online the twelfth and final release of the SDSS-III. Consulted by anyone using the “Sky Server”, the observations and spectroscopic measurements of the Sloan Digital Sky Survey are one among the richest and most impressive astronomical archives ever made. Half a billion stars
