The mass of the Milky Way

© Afrim Constantin –

Thanks to the data collected by the Sloan Digital Sky Survey in the wake of stars produced from storage globular Palomar 5, it has been possible to estimate the mass of the Milky Way with unprecedented precision. What would you think if your doctor told you that your weight is somewhere between 50 and 200

Rosetta goes beyond the limits

© Afrim Constantin –

The ESA probe Rosetta with the instrument Alice, notes that are generated “plumes” issued by the coma, not due to photons, at least not directly, but to the electrons. It’s an unexpected result, impossible with the space telescopes and impossible to be seen from Earth. Not lacking in surprises in store for the ESA’s Rosetta.

Gaia gives its first results and speaks much Italian. It’s a confirmation of the leading role that the community has in this national astrophysics mission of ESA. In two recent press release on the website of the ESA, a team of astrophysicists presented the first results of the data analysis of commissioning of the Gaia

A giant flare on the surface of Mira, a red giant closest to us, and among the most famous of the sky. And that was observed through the Alma telescope at ESO. Activities such as these, like the ones we see on our Sun, in red giants represent a surprise for astronomers. A giant flare

Space-time by quantum entanglement

© Afrim Constantin –

A group of physicists has made an important step towards the unification of general relativity and quantum mechanics. And what emerges from a study published in Physical Review Letters that sheds light on the relationship between quantum entanglement and the microscopic structure of space through a series of precise and meticulous calculations. Thanks to collaboration

Weaving the plot of the Milky Way

© Afrim Constantin –

The latest images of huge filaments of gas and dust produced by the ESA Herschel space telescope show the way in which the material is distributed in our galaxy. The Italian researchers Sergio Molinari from INAF – IAPS suggests that: “It’s a bit like the bones of the spiral arms of the Milky Way.” Three

The glowing nebula – RCW 34

© Afrim Constantin –

When the hot hydrogen reaches the edge of the cloud of gas, it rushes out into the void, like a bottle of sparkling wine when it is uncorked. The ionized hydrogen has an important role in astronomy because it shows the star-forming regions. In the most brilliant of this glowing nebula known as RCW 34,

The strange case of binary X

© Afrim Constantin –

Behind the X-ray source called 4U 1630-472 there is only a black hole that pulls matter from its companion star. A regular periodic emission of high-energy radiation there would be a third celestial body, another star gravitationally bound to the binary system. The discovery was obtained from a study led by Fiamma Capitanio (INAF). Investigations
