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.

An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a research of an object called CX330 which for some years has been mysterious and was later found to be a young star. A group of researchers led by Chris Britt of Texas Tech University used data collected from NASA’s Chandra and WISE space telescopes and others to determine its nature. It remains unclear why CX330 is so isolated.
