Few days ‘till the meeting

© Afrim Constantin –

There are now only about ten days meeting between the New Horizons probe and the Pluto system. No new moon discovery, but in the last images of the dwarf planet they arouse curiosity of the big dark and very regular spots. The presence of methane ice was confirmed. ‘All clear’, all alone on the route

The new maps of dark matter

© Afrim Constantin –

A preliminary survey of the sky, made a new room off the field installed at the Japanese Subaru Telescope, allowed astronomers to reveal well-9 concentrations of dark matter. The findings, published in the Astrophysical Journal, are comforting to understand the role of dark energy in connection with the expansion of the Universe. The next step

The film of quantum waves

Observed and “filmed” for the first time in a direct way, the wavy nature of molecules of nitrogen in rotation. The technique opens up new possibilities for molecular manipulations on the border between reality and quantum classical reality. The results are published in the journal of Science Advances. The cast is not exactly the ones

Fewer galaxies in the early Universe

© Afrim Constantin –

How many faint galaxies can we observe? It’s a tricky question that sought to answer a group of researchers at Michigan State University (MSU) through a series of numerical simulations conducted with supercomputers. Their findings, published in the Astrophysical Journal Letters, suggest that the origins of the universe might be a little crowded place, implying

Farmers in the outer space?

Instead of heavy, bulky and not very environmentally friendly light bulbs, experts believe that red and blue light emitting diodes will be the solution for growing plants (such as lettuce and tomatoes) in space, even during long-duration missions such as the one on Mars. Future astronauts destined for long-duration missions as to Mars, and, who

The cosmic expansion towards the Big Rip

© Afrim Constantin –

Three physicists from Vanderbilt University have introduced a new mathematical formulation to treat fluid dynamics relativistic. The study, published in Physical Review D, has important implications for the ultimate fate of the universe and could shed light both on the nature of dark energy. Although this is a promising approach, however, it needs further analysis

How the nucleus of a galaxy forms?

© Afrim Constantin –

A study coordinated by Wisdom (first author Manuel Arca Sedda University of Tor Vergata), investigated the formation of the core of galaxies like ours, and in particular on the relationship between supermassive black holes (SMBH) and nuclear star clusters (NSC). Galaxies like the Milky Way, which belongs to our solar system, are the focuses of

Ex-Terre born between arms powder

What prevents the grains of dust in a protoplanetary disk plunging towards the young star at its center and thus enable it to gather and maybe form rocky planets? One possible answer is given to the study of Alan Boss, of the Carnegie Institution for Science in Washington, published in the journal The Astrophysical Journal.
