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

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

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

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.

It’s still early to say, but maybe it was discovered the first example of a “rejuvenated” planet. In the case, it would be a giant planet survived the red giant phase of its parent star and rekindled by matter lost by the dying star. As in a hypothetical sequel science fiction film Youth of Paolo

The active galactic nuclei (AGN) are not ‘shining’ perpetually. And the result of a study conducted by researchers in Zurich that the average life of an AGN lasts 200,000 years. The results, published in Monthly Notices of the Royal Astronomical Society, provide new clues about how these objects can influence the formation and evolution of

The astronomers used a method that exploits the geometry of the echoes light products following an outburst of a neutron star in a binary system. The results of this study, reported in the Astrophysical Journal, allow us to experiment with a technique that could be used to estimate distances sources X. Now astronomers know that
