An article published in the “Astrophysical Journal” describes the discovery of the remnants of a galaxy of which only a small core remained after passing through a larger galaxy. A team of astronomers used the VLBA radio telescope to find this unique object cataloged as B3 1715+425 with a diameter that is now only 3,000 light-years and a supermassive black hole at its center.

An article accepted for publication in the journal “Monthly Notices of the Royal Astronomical Society” describes a research on the large columnar structures in the Carina Nebula. A team led by Anna McLeod, a PhD student at ESO, used the MUSE instrument installed on ESO’s VLT (Very Large Telescope) to examine these structures that have been nicknamed “pillars of destruction” for certain similarities with the “Pillars of Creation” photographed by the Hubble space telescope.

An article published in the journal “Nature” describes the discovery of a triple system in formation. An international team of scientists used the Atacama Large Millimeter / submillimeter Array (ALMA) and Karl G. Jansky Very Large Array (VLA) radio telescopes to observe the system called L1448 IRS3B, where a disk of dust and gas is fragmenting into a multiple star system.

Two articles published in the journal “Science” provide new information about the birth of Mare Orientale, a big impact basin on the Moon. Researchers used data collected by NASA’s GRAIL mission to reconstruct the formation of Mare Orientale, helping to better understand how impact craters with concentric circular structures form.
