ESO’s telescope ALMA (Atacama Large Millimeter / submillimeter Array) in Chile allowed to take the most detailed images ever obtained of a galaxy called HATLAS J090311.6+003906 or SDP.81. It’s about 11.4 billion light years from Earth and its light is distorted by the phenomenon called gravitational lensing. A galaxy between it and the Earth distorts its light with its huge gravity and the result is that we see an almost perfect ring, called an Einstein ring.
An article published in the journal “Astrophysical Journal” describes a study that established a link between the presence of supermassive black holes that emit jets of materials to nearly the speed of light but also radio waves and galaxy mergers. An international team of astronomers led by Italian INAF researcher Marco Chiaberge used the Hubble Space Telescope in the most extensive survey of the kind ever conducted.
An article published in the journal “Astrophysical Journal” describes the discovery of the brightest galaxy of the universe made using data from NASA’s space telescope WISE. Known as WISE J224607.57-052635.0, it emits light equivalent to that of over 300 trillion suns. It belongs to the ELIRG (Extremely Luminous Infrared Galaxy) class recently identified thanks to WISE.
A team of scientists used the Hubble Space Telescope to measure the extent of the halo of the gas surrounds the Andromeda galaxy. It turned out to be much larger than expected stretching for about a million light-years from the galaxy. This means it reaches out to about half the distance that separates it from the Milky Way so if it was visible to the naked eye its size would be about a hundred times that of the full Moon. The results of this research were published in “Astrophysical Journal”.
An article published in the journal “Nature” describes a research carried out using NASA’s space telescope NuSTAR (Nuclear Spectroscopic Telescope Array) to examine the central area of the Milky Way. A mysterious glow shows an amount of X-rays higher than expected and could be caused by emissions from zombies stars.
