The giant halo of Andromeda

© Afrim Constantin –

Thanks to the data collected by Hubble a team of scientists was able to accurately estimate the size of the halo of Andromeda gas: about half of the contents of the stars in the same galaxy. This discovery allows us to learn more on the evolution and the structure of one of the most common

Mercury – magnetic field

© Afrim Constantin –

Thanks to NASA orbiter flybys made in the months close to the crash site, traces of magnetization in the crust of the planet were found. This was based on a core of molten iron that in ancient times, that would act as a dynamo. The study was published in Science. The investigation of MESSENGER orbiter

The shot was taken in October 2014 when the Atacama Large Millimeter / submillimeter Array in Chile showed excellent and never before seen details in the protoplanetary disk of this young system. An animated debate has always been encountered between astronomers because around the concentric circles dark, it would hide planets in formation. A group

55 Cancri, also cataloged Rho1 Cancri or abbreviated 55 Cnc, is a binary star approximately 41 light-years away from Earth in the constellation of Cancer. The system consists of a G-type star and a smaller red dwarf, separated by over 1,000 AU (one thousand times the distance from the Earth to the Sun). Astronomers have

The most distant galaxy ever observed

© Afrim Constantin –

It’s called EGS-zs8-1 and it is a particularly bright object that existed at a time when the Universe was only 670 million years after the Big Bang. The results of this study, obtained with the spectrometer MOSFIRE installed at the telescope Keck-I and published in Astrophysical Journal Letters, provide new clues about the massive primordial

Quasars are “eating” a huge amount of matter

© Afrim Constantin –

Astronomers have found a population of black holes characterized by a thick accretion disk. Analysis of the data suggests that these objects, called quasars, are consuming a huge amount of matter at an extraordinary rate. The results of this study, published in the Astrophysical Journal, will provide new clues on the evolution of supermassive black

Killer asteroids and volcanic eruptions

© Afrim Constantin –

A study led by scientists at the University of California suggests that the impact occurred 60 million years ago off the Yucatan peninsula might have triggered the massive eruptions of lava of the Deccan, India. The asteroid that crashed into the ocean off the coast of Mexico 66 million years ago causing the extinction of
