At the workshop “Chandra Science for the Next Decade” being held in Cambridge, Massachusetts, a new image was presented showing a supernova remnant called G11.2-0.3 obtained using NASA’s Chandra X-ray Observatory. For years these were considered the remnants of the supernova recorded by the Chinese in 386 A.D. and for this reason known as SN 386 but new exams indicate that it was a different supernova.

An article published in the journal “Nature” describes a research about the molecular cloud located behind the Orion Nebula. A group of researchers used the HAWK-I instrument installed on ESO’s Very Large Telescope (VLT) and the ALMA radio telescope, both ESO’s, to look at key moments of astrochemical phenomena, meaning the chemical reactions that take place in space and in this case in that area and one day will lead to the birth of new stars.

An article published in “The Astrophysical Journal Letters” describes a research about the dwarf galaxy DDO 68. An international team of researchers led by Francesca Annibali of the National Institute for Astrophysics (INAF), Italy, used the Large Binocular Telescope (LBT) to make observations that allowed to find evidence that even a very small galaxy can capture smaller galaxies.

An article published in the “Journal of Geophysical Research” describes a research funded by NASA on the atmosphere of Io, one of the “Galilean” moons of Jupiter. A group of scientists led by Constantine Tsang of the Southwest Research Institute detected the changes taking place in the atmosphere of Io, noting how it collapses when it enters Jupiter’s shadow and the temperature drops.

A photograph taken by the Hubble Space Telescope shows the remains of a star that died long ago. Those are wisps of ionized gas that still emit a faint glow, the last product of the immense energy generated in a Type Ia supernova. These supernova remnants called DEM L316A are located in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, about 160,000 light-years away from Earth.
