Last October a picture of the system HL Tauri captured by ESO’s ALMA (Atacama Large Millimeter / submillimeter Array) telescope was published. It showed a disk of dust that is slowly coalescing and was one of the sharpest images ever made at sumbillimetric wavelengths. According to many scientists there are planets that are forming in the system but others were skeptical and that created a debate. Now a team of astrophysicists from the University of Toronto led by Daniel Tamayo brought new evidence that there really are planets forming, published in the journal “Astrophysical Journal”.
Between April 28 and 29, 2015 a solar flare produced a filament that spread to a really huge distance. The result is that the images of the space probe SOHO (Solar and Heliospheric Observatory) that captured the filament, to include it cover a wide area of 45 million kilometers (about 30 million miles).
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.
An article published in “Astrophysical Journal” describes the diskovery made by a group of astronomers led by Sayan Chakraborti of the Harvard-Smithsonian Center for Astrophysics (CfA). They studied a supernova called 2012ap (SN 2012ap) which is a missing link between ordinary ones and the ones that cause the emission of a gamma-ray burst.
For many years, scientists have known that complex molecules can form in space, including some important in the birth of life forms. This month, two studies have been published that prove the presence of various molecules of this type in an infant solar system and even in protostellar clouds in which Sun-like stars are formed together with their planets.
