The traces of various molecules in the protostar's emissions seen by ALMA along with an infrared view

An article published in “The Astrophysical Journal” reports the discovery of complex organic molecules around a protostar at the edge of the Milky Way. A team of researchers led by astronomer Takashi Shimonishi of the Niigata University, Japan, used the ALMA radio telescope to examine the area around a protostar in the region cataloged as WB89-789 detecting the presence of molecules such as methanol, ethanol, methyl formate, dimethyl ether, formamide, propanenitrile, and others. This is the first time that complex organic molecules, the kind that can form prebiotic molecules, have been discovered at the edge of the Milky Way, and this suggests that they can form with an efficiency similar to that existing within the galaxy, in the Sun’s “neighborhood”.

The galaxy NGC 7727 and its pair of supermassive black holes seen by the VLT

An article published in the journal “Astronomy & Astrophysics” reports the detection of a pair of supermassive black holes in the galaxy NGC 7727. A team of researchers used ESO’s VLT to conduct the observations that led to a discovery that broke two records in this field. The two supermassive black holes are the closest pair discovered so far at about 89 million light-years from Earth and are the closest to each other, as their distance was estimated to be around 1,600 light-years.
