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.
A research conducted by a team led by astronomer Peter A. Milne of the University of Arizona published in two articles in the “Astrophysical Journal” shows that Type Ia supernovae can be divided into two groups with different characteristics. For years, astronomers had thought that their brightness depended almost exclusively on their distance. This can have consequences on our knowledge of the universe expansion, also calculated based on this type of supernovae.
